This article is written for automobile owners who have noticed that their water pump leaks even when the motor is turned off.

Does A Bad Water Pump Leak When The Engine Is Off?

You must determine whether or not your car is leaking water and whether or not it is water. It is possible that there is a leak in any of these places. Coolant and oil are both possibilities. You must determine whether or not the liquid is water. You might place a piece of paper beneath the suspected leak. If there is only a little amount of fluid, you must examine for the density and color of the fluid. It is possible that the coolant will become blue. Oil has a distinct smell that is easy to identify.

One of the causes for water leaking from your vehicle’s air conditioner is that it is not functioning properly.

The moisture in the air can cause the water to condense on the air conditioner, which might cause it to malfunction.

When your air conditioner is running, you may prevent water from leaking into your car by turning on the recirculation feature on the unit.

Why Does My Car Leak Water When I Turn It Off?

The majority of the time, the water pouring from under your car is caused by condensation from the air conditioning system or the exhaust. Most likely, the water surrounding the rear of your engine compartment is condensation from your air conditioning system. This, on the other hand, is typical and does not indicate a serious concern. Exhaust condensation is indicated by the presence of water surrounding your exhaust. Most of the time, exhaust condensation is not a problem unless you notice massive clouds of white condensation coming from the exhaust.

  1. As a result, it is possible that your head gasket has been blown.
  2. When the air conditioning is switched off in your vehicle, it is possible that the vehicle will leak.
  3. Within your air conditioner’s pool of condensation lies a buildup of moisture.
  4. After that, you should inspect your exhaust.
  5. The combustion process of the fuel might result in a system that is propelling a little amount of water out of the system.
  6. It is also necessary to inspect the cooling system.

A problem with your windshield washer system might potentially be the cause of your problem. It’s possible that the water is coming from your windshield washer system. Additionally, there may be some bodily harm caused.

How Do You Know If Your Water Pump Is Leaking?

There are a variety of factors that contribute to your vehicle’s water leakage. First and foremost, you must consider whether or not your car is leaking water. It should be checked completely, and then the color should be examined closely. If the liquid is yellow, green, or blue in color, it is possible that it is a coolant rather than water. If the water is clear, it is possible that there is water in the cooling system. After that, you’ll need to figure out where the leak is. Locate the spot where the puddle has formed for the location.

If the puddle is located near the muffler or tailpipe, it is possible that condensation from the exhaust has formed.

If you notice that there is a slight amount of condensation developing when the air conditioner is running, this is rather common.

Does A Water Pump Only Leak When Running?

Many factors might contribute to the leakage of water from your car. First and foremost, you must consider whether or not your car is leaking liquid. It should be checked properly, and then the color should be carefully observed. Water can be confused with coolants if the liquid is yellow, green, or blue. The presence of water in the cooling system is possible if the fluid is transparent. In order to locate the leak, you must first determine its location on the pipe system. Locate the spot where the puddle has formed for the purpose of determining the location.

There may be condensation from the exhaust if the puddle is located near the muffler or tailpipe.

In most cases, if the air conditioner is running, you will notice a slight amount of condensation on the windows and doors.

How Long Will A Water Pump Last After It Starts Leaking?

This means that the typical lifespan of your water pump will be the same as that of your timing belt. A water pump has a typical lifespan of sixty thousand miles (60,000 kilometres) to nine thousand miles (90,000 km) (90,000 miles). This is with a high-quality vehicle. You must take good care of your vehicle, and you must change your coolant on a regular schedule. Your car’s water pump’s lifespan may be shortened if the coolant in your vehicle is contaminated.

What Will Stop A Water Pump From Leaking?

It is necessary to pour a liquid radiator or water pump stop leak product into the radiator of your automobile. In the front of the engine, you’ll find your radiator. The stop leak product will be poured into the radiator, where it will run into the water pump seal, where it will either completely seal or significantly slow the leak. You must make certain that your radiator is not too hot to touch. Before you may pour the solution into your radiator, your car must be running. The stop leak product is not intended to be a long-term solution, but rather a temporary one.

You must be aware of the specific make, year, and model of your car in order to acquire the appropriate water pump for it.

Purchase the repair handbook for the exact car. Every car is unique, and you will need to consult the owner’s handbook for your vehicle in order to replace the water pump correctly.

Will Water Pump Leak If Engine Is Off? – McNally Institute

During this test, you will switch off your engine to avoid any engine noise, but the cooling fan will not be able to circulate any air because the engine is not running. Leaks in the cooling system can be quickly found as a result of this. Because it appears to be leaking, there is a fair chance that the top hose has dripped into the shaft and caused the leak.

Will A Water Pump Leak When Not Running?

When the automobile is not running, how high will the coolant leak rise if the ntopment leaks out? It is possible for your car’s coolant system to leak when it is parked. It’s possible that a faulty component in your vehicle’s cooling system is causing this problem. Additionally, a malfunctioning radiator, an ineffective fan, or a warped head gasket may be to blame for this problem.

Can Coolant Leak When Car Is Off?

During the cooling time that follows the turn-off of the engine, the automobile loses its coolant. Specifically, it refers to the process by which the engine releases pressure from the cold coolant by allowing pressure from the hot coolant to build up inside the machine when the hot engine is turned off. When the hot engine is turned off, pressure built up by the expansion of the hot coolant is forced out of the radiator through the radiator cap and return hose.

How Long Will A Water Pump Last After It Starts Leaking?

Water pumps can fail for a variety of causes. Water pumps have a lifespan of 60,000 to 90,000 miles if they are maintained properly, which is comparable to the lifespan of timing belts. Most low-cost water pumps will leak for up to 30,000 miles in the first few years of operation, if not more.

How Do You Know If Your Water Pump Is Leaking?

  • If you smell yellow/green antifreeze (also known as radiator fluid) pouring beneath your automobile, you may have a leak under your car’s foundation. How loud is the whining coming from your engine compartment? A whine may be heard coming from this location if you’re driving
  • It’s possible that this engine is overheating.

Why Is My Car Leaking Water When Parked?

Water leaking from beneath a car is rather frequent, and it is usually caused by condensation from the air conditioning system or from the exhaust pipes. Condensation on your air conditioning system might be the source of any water you detect at the back of the engine compartment. The fact that this is happening is not exceptional, nor does it have any significance.

How Long Will Water Pump Last If Leaking?

They have a useful life of 60,000 to 90,000 kilometers when kept in great condition. Water pumps that are less than $30k in price, on the other hand, are more prone to leaking. The most effective strategy to ensure that your water pump operates correctly is to get your coolant replaced on a regular basis.

Can A Water Pump Leak And Still Work?

If you fill the reservoirs completely with coolant, you may be able to drive your car for a short period of time while the coolant is being absorbed into the system. If the repair is not made as quickly as feasible, the engine leak may become more severe. Make contact with a repair business and, if required, go immediately to them.

Why Does My Radiator Leak When Car Is Off?

This may have been caused by an improperly functioning water control valve, which prevented a smooth flow of coolant from the heater core to the motors, resulting in the problem being remedied.

The heater may not be working properly, or the coolant may need to be replenished, as may be noted.

Is It Normal For Coolant To Leak From The Bottom?

The quantity of water hoses or pipes in a cooling system is a sufficient number of connections. Over time, the hose has grown brittle or cracked as a result of its breakdown tendencies or the tremendous heat it has been subjected to. It is possible that leak spots will form if the fractures continue to expand. When coolant leaks occur, they are frequently attributed to ruptured hoses located at the engine’s foundation.

What Happens If Your Water Pump Is Leaking?

In a cooling system, a suitable amount of water hoses or pipes is provided for. In the long run, the hose has become brittle or cracked as a result of its breaking down qualities or the tremendous heat it has been exposed to. When fractures continue to grow, it is possible that leak spots will form. Coolant leaks are frequently caused by leaks in the engine base that are the result of worn out hoses.

Watch Will Water Pump Leak If Engine Is Off Video

There are occasions when it might be difficult to locate the cause of a coolant leak from your car. The situation might be made much more challenging if the coolant leak only happens when the automobile is not in motion. So, you might wonder, why would coolant leak from a car that is not running? Coolant can leak from a vehicle that is not in motion because, when the engine is turned off, the coolant is no longer under pressure and can pool in various locations around the engine, eventually causing the car to leak coolant.

How Can Coolant Leak From A Car That Isn’t Running?

You might believe that a hot engine operating under pressure is more prone to lose coolant than a cold engine running under pressure. This is true in some cases, particularly when a component, such as a water pump or a ruptured hose, has completely failed and cannot be repaired. In reality, when the engine is switched off and the car is parked, it is more probable that coolant will leak from the engine block. As a result, when the engine is running, the water pump is transferring the coolant throughout the cooling system under pressure, and in most situations, the coolant will not have a chance to collect in a spot where it may leak.

Where Can Coolant Leak From When The Car Is Not Running?

As soon as your vehicle is shut off, the coolant ceases to circulate and tends to pool in various spots around the engine until the vehicle is turned on again. If they are broken or cracked, the following are some of the places where coolant will leak.

1. From A Leaky Heater Core

The indications of a faulty, leaking heater core are as follows: such as a foul odor in the car, wet carpet caused by fluid seeping from beneath the dashboard, windows that are continually fogged up, and a car heating system that does not function properly. When it’s chilly outside, the heater core is in charge of keeping the inside of your car warm while driving. The air that comes out of the vents in the automobile will not be as hot as it should be if the heater core in the vehicle is not functioning correctly.

See also:  How To Turn Up Hot Water Heater

When the automobile is turned off, it is common for fluid to leak from a damaged heater core.

There is a good likelihood that your car’s carpet is damp and that the interior smells like an engine compartment. This indicates that the heater core is leaking.

2. From A Loose Coolant Hose Clamp

Sometimes a coolant leak may be traced back to one of the several hoses that make up the vehicle’s whole coolant system. If the leak is only apparent while the car is not running, it is possible that the source of the leak is the junction where the hose is fastened to the engine’s cooling system. As the engine heats up, the clamps that keep the coolant hoses in place might occasionally expand a tiny bit. This is normal. This has the potential to cause the hose to loosen somewhat, which might result in leaking.

3. From A Leaking Radiator

This can frequently be the source of a coolant leak if the radiator is broken or otherwise damaged, especially while the automobile is not in use. When the engine is operating, the coolant in the hoses and radiator is being pushed around the engine at a rapid rate and at a constant temperature. Coolant is drawn from the hot sections of the engine and directed through the radiator, where it is cooled before being returned to the engine’s hot parts again. It is possible that a minor fracture or hole in one of the radiator fins, or where the feeder hoses connect to the radiator, will allow a little quantity of coolant to escape while the engine is operating.

4. From A Loose Or Faulty Radiator Drain Valve

When draining and cleansing the coolant system, certain car radiators are equipped with a drain valve that must be removed in order to do so. If it becomes loose or if the rubber seals fail, this can also become a source of coolant leakage. Just as with a leaking radiator, when the engine is shut off, the coolant can escape via the drain valve into the atmosphere. Typically, drain valves are positioned near the bottom of the radiator, making it easier for coolant in the radiator to escape if the valve becomes faulty.

When doing a coolant service, it’s always a good idea to replace the valve in the engine.

5. From A Failing Water Pump

A frequent symptom of a failed water pump is fluid loss from the coolant system or leakage from the water pump. When a water pump fails, it has a built-in safety device called a weep hole, which can alert you of the oncoming failure of the pump. When one of the internal seals on the water pump fails, this small, unplugged hole on the water pump enables coolant or oil to leak from the inside of the water pump. This indicates that the internal oil seal has failed and oil is pouring from the opening.

The vehicle’s engine cooling system was disconnected due to a faulty water pump.

It is possible that a failing water pump sealing gasket is responsible for a substantial volume of coolant escaping from the water pump when the automobile is switched off. The gasket between the water pump and the engine block is referred to as the water pump gasket.

How To Locate The Source Of A Coolant Leak That Only Occurs When The Car Is Turned Off

The procedure for locating a coolant leak that only occurs while the engine is turned off is quite similar to the procedure for locating any other type of coolant leak. Pressure testing the coolant system is the most effective method of locating a coolant leak rapidly. Pressure testing the technology allows you to mimic coolant pressure without the need to start the engine beforehand. It is also simpler to check for leaks at various coolant pressures, as well as leaks that only occur when there is no coolant pressure applied.

How To Pressure Check A Car For Coolant Leak When Turned Off

The first step is to check the level of coolant in the coolant reservoir and, if required, top it up with water before you begin. Avoid topping it off with coolant since you’ll only waste coolant if there’s a leak in the system, which is quite unlikely. Step 2– In order to pressurize the system, you’ll need a portable pressure tester. The purchase of a large, expensive equipment is unnecessary; a simple pressure tester with many adapters, such as thisMityvac kit would suffice (Amazon.com link).

  1. (This information should be printed on the cap.) It is possible that you may need to use an adapter to attach the pressure tester to the coolant reservoir.
  2. It is possible to hear coolant pouring from the system as the pressure in the system is increased if a leak exists in it.
  3. 4.
  4. Licking is common near hose connections, at the bottom of radiators, around the water pump, and at the base of coolant reservoirs.
  5. Continue this procedure until the system has been completely de-pressurized.
  6. Allow 30 minutes for the engine to cool before inspecting it again.
  7. By employing this procedure, you will be able to determine if there is a leak someplace in the engine compartment.

It is possible that you may need to unscrew the dashboard in order to access the heater core and check for leaks. How to Perform a Pressure Test on Your Vehicle’s Cooling System

5 Signs Your Water Pump May Be Failing

The fact that you need to replace your oil and check the oil level in your car on a regular basis to ensure that it runs smoothly is common information, but did you know that the water pump is just as critical to the smooth operation of your automobile as the oil pump? While it may not be as evident as the engine or brakes, your car’s water pump is extremely important in keeping you and your passengers safe on the road. Your car’s engine contains a plethora of components that, while in operation, generate an enormous amount of heat and friction.

The absence of a properly functioning water pump may cause your engine to overheat during the summer and freeze during the winter months.

Maintaining your water pump with the same level of care that you do your vehicle’s oil can help you prevent these types of big and expensive repairs down the road.

5 Symptoms of a Failing Water Pump

It’s critical to get familiar with the telltale indicators of a failing water pump in your home. If you don’t do something, you might not notice the problem until it’s too late. If your water pump malfunctions, you run the danger of causing irreversible damage to your engine, which is a costly issue that should be avoided at all costs. These five indicators might assist you in determining whether it is necessary to bring your vehicle in for an examination and possibly water pump repair.

1. Coolant Leaking

Having a puddle of coolant on the ground where you’ve parked your car is one of the first symptoms that your water pump may be malfunctioning. The pump is comprised of a number of different gaskets and seals, all of which will ultimately dry up, crack, or fail over time. When this occurs, the coolant will leak from the pump’s reservoir. Immediately take your vehicle to a repair shop if you see an orange, green, pink, or blue pool of liquid after pulling out of your driveway after it has been sitting for a long period of time.

2. Rust or Deposit Build-Up

When there is a little leak in the water pump, there will be a progressive buildup of muck or rust on the pump’s internal parts. Use of incompatible coolant or a faulty pressure cap that enables air to enter the system can both result in this condition occurring in the engine. In either case, your pump’s efficiency in moving coolant through the engine will deteriorate, eventually leading to full failure of the system. An excellent routine involves lifting your hood and inspecting the inside of your engine.

You’ll be able to identify issues as they arise, rather than having to wait for the dreaded “check engine” light to illuminate. The water pump in your automobile should be changed if you see any corrosion, pitted spots, or build-up surrounding it. Bring your car in to get it checked out.

3. Noise

Is your automobile making a whining sound as you accelerate? This irritating, high-pitched sound might be created by a loose accessory belt, which could be the source of the problem. Loose belts are frequently the consequence of a misaligned pulley or worn out bearings, which must be repaired or replaced. It’s important to get your car checked out if you hear a whining sound coming from the front of the engine to prevent the possibility of a failing water pump and a much more expensive replacement.

There are various belts in your engine, including a serpentine belt, that can cause catastrophic damage to your engine if they slip, break, or snap.

It will save you from being stranded on the side of the road if you have your belts replaced according to the maintenance plan for your car.

4. Overheating

Is the temperature gauge in your vehicle increasing in temperature? It’s possible that your water pump is on its way out of commission. Overheating your automobile poses a threat to you and other drivers since it increases the likelihood of engine failure. Whenever you detect that your vehicle is overheating, take it to your technician for a check right away. If you find yourself in an automobile emergency, it’s crucial to know what measures to take in order to reduce the danger of injury to yourself and other drivers, as well as to your vehicle.

Pull over, contact for a tow truck, and get your car diagnosed as soon as possible.

5. Steam

In the event that you notice steam coming from beneath your hood, it is a warning that something major has gone wrong with your vehicle. When a water pump breaks fully, it is no longer able to flow coolant through the engine, resulting in the engine overheating as a result. If you notice steam coming from your engine, pull over immediately and contact your technician for assistance. Continuing to drive with an overheated engine can cause significant damage to the engine, which may necessitate a total engine replacement.

How to Tell if my Water Pump is Bad

Having a faulty water pump might result in a variety of issues with your automobile.

If you’re wondering “how to tell if my water pump is faulty,” it’s likely that you’re already experiencing some of the issues that come with it.

What does a water pump do?

In order for a car’s cooling system to function properly, the water pump is the primary driving force behind it. All modern automobiles are equipped with a radiator located at the front of the vehicle, which is responsible for cooling the antifreeze in your vehicle. Water pumps are found in most cars and are responsible for drawing coolant from the radiator and pumping it into your engine block, cylinder heads, and any other components that need to be cooled such as an oil cooler, throttle body, and/or turbocharger, if your vehicle is equipped with one.

  1. If the water pump in your automobile breaks, the driving power for the coolant is quickly depleted, causing the water in the engine to heat up extremely quickly and your engine to overheat, perhaps causing serious damage.
  2. First and foremost, a catastrophic failure of your water pump is possible, but not probable.
  3. This form of water pump failure is the most hazardous, despite the fact that it is quite unlikely.
  4. A damaged motor belt or engine noise might accompany this situation in your car, but your engine temperature gauge will almost certainly rise swiftly as a result of this.
  5. The failure of a bearing in your engine’s water pump is a more likely cause of water pump failure.
  6. Due to the fact that your water pump bearing is either a sealed bearing or is lubricated solely by coolant, it has the potential to wear out far more quickly than the oil-lubricated bearings in your engine.
  7. Occasionally, you may be able to see the pump pulley or belt swaying when your engine idles in the most extreme situations.

If this is the case, the most straightforward solution is to just replace your water pump.

This might comprise the shaft seal as well as the seal connecting the water pump to the block.

If the shaft seal on your water pump has become worn and is leaking, the most cost-effective solution is to replace the pump entirely.

Significant amounts of stress are placed on the region around your water pump as a result of the heating and cooling of your engine in that area, and it is therefore susceptible to cracking.

You may quickly and simply repair any leaks caused by broken blocks near your water pump by using BlueDevil Radiator and Block Sealer, which is available at most hardware stores.

Or, even worse, experiencing the effects of a faulty water pump while on the road and in the driver’s seat. It’s a good idea to be aware of how to detect whether the water pump is malfunctioning and to inspect and repair it before the relocation, if required. During this lesson, we’ll go over the symptoms and indicators of a failed pump.

Can a Bad Water Pump Cause a Blown Head Gasket?

The water pump, despite the fact that it is buried deep within the engine and that we don’t tend to think about it, is an essential component of the engine and of the vehicle in general. In this case, failure to diagnose and cure the problem might result in irreversible damage to the engine and the vehicle. Failure to repair or replace the malfunctioning water pump on your vehicle in a timely manner may result in the damage to your vehicle becoming more serious over time. As a consequence, you may expect to see scorched pistons, fractured cylinder heads, and even a burst head gasket, which will result in thousands of dollars in repairs, and even more for some of the most costly automobiles on the market today.

Coolant Leak After Engine is shut off and at operating temperature.

After that, there was a coolant leak. The engine has been turned off and is at working temperature. As is customary, I drove the shark to work this morning, but this time I was greeted with the lovely fragrance of burning coolant as I pulled into the parking lot. So I did a brief inspection of the underneath of the car as I parked it, but there were no leaks to be discovered, so I carried on to my place of employment. When I got outside after approximately 4 hours, there was a 6 inch wide pool of green water seeping from the front of the vehicle.

  • a little closer to the center of the oil pan.
  • I started the car and cranked it up.
  • I reasoned that it could be necessary to have it at working temperature.
  • There are still no leaks.
  • If it was the WP, I am not sure what happened, because it did not spill out in any way.
  • Another green puddle had formed right beneath the front of the oil pan, and when I returned, I discovered another one there.
  • I double-checked all of the hoses, as well as the resevoir and radiator.
  • The only item that comes to mind that may be causing the problem without jacking up the car is the water pump.

I’m simply puzzled as to why the puddle doesn’t appear until the car has cooled down a little bit. I sat and observed it after it had reached its maximum temperature and shut off. Any assistance would be greatly appreciated. 83 928S Automatic Transmission,

Coolant leaks after the engine is turned off, why?

On July 17, 2005, at 11:16 p.m., Burning BrakesThread Starter is a thread starter that burns brakes. Date of joining: September 2002 Location: Canada, in the greater Vancouver region Posted 1,155 times, received 0 likes, and received 1 like on a single post. What causes coolant to leak after the engine has been shut off? It began a little more than a week ago. When I switch off the vehicle after driving it for a period of time (e.g., 1/2 hour), it loses a significant volume of coolant via the overflow tube in the reserve coolant tank.

  • Is there anyone who can tell me what the problem is?
  • I don’t believe it occurs while I drive (i.e., when the water pump operates), because the car does not overheat, and I have never noticed it when the car is stopped but the engine is still running.

If you have the six-bladed fans, one of them will remain on until the water temperature decreases to prevent hoses from being damaged, like on the later cars.

As a result, I felt I had a defective cap on my 84 and installed one rated at 13 pounds per square inch.

It’s just that there’s too much pressure piling up.

According to the information provided above, this is incorrect.

As of right now, I do not have any leaks, but I will replace the cap if necessary.

Thanks in advance.

It appears to happen everytime something goes wrong with my automobile.

Will an autozone/advance auto radiator cap suffice in this situation?

Is it possible for a malfunctioning radiator cap to result in overpressurization of the cooling system?

If the cap is not properly sealing, there is a leak.

The checker displays a 13 for the 84 and a 16 for the 87.87951 in the example. It appears that my 13psi cap will be plenty for 1983. Thanks. The annoyance of the leak has been eliminated. 944,car,coolant,engine,large,leak,leaking,leaks,passat,radiator,run,somethings,sounds,turn,turned,vw

Coolant leaks out AFTER shutting car off?

HalfDork 26th of May, 2008, 6:35 p.m. So, over the weekend, I took the Lotus out for a short trip (about 100 kilometers) with the German Lotus Club. It was the first time I’d actually taken the vehicle out for a proper boot, and it had been pretty cooperative throughout the process. After leaving it (in the warmth) for a bit, I returned to see a large puddle beneath. It’s possible that a litre of coolant had leaked from somewhere after I’d turned off the automobile. It was the first time I’d ever witnessed something like this.

  1. (Before anybody asks, no, it is not condensation from the A/C; it is instead antifreeze.) No drips or squirts occur while the motor is operating, and although it did not come out straight away, I sat and observed for a few minutes after it was turned off.
  2. Driving at a regular speed, the temperature is OK (according to the gauge, which may or may not be true – some of my other gauges aren’t working properly right now), the fans turn on as they should, and I don’t HEAR the coolant boiling or anything else that would suggest that I’m overheating.
  3. Some recommendations for topics to check into would be much appreciated!: J Check the hose clamps for tightness.
  4. When the coolant warmed up (was there too much pressure in the system?
  5. It was resolved with the use of a genuine hose clamp.
  6. It happens that they leak while they are not spinning or when they are in specific locations.
  7. Remove, or at the very least loosen, the belt till you are able to turn the shaft of the pump.

If you’re able to get in there without burning your arm, try it with the engine still heated.

I’d already had this problem.

Is there a tank to catch the overflow?

After stopping, the coolant becomes significantly hotter and expands.

When there isn’t enough area for the expansion of the tank, it will overflow even if there is an overflow tank in place.

I experienced a problem with coolant leaking from the front of the engine around a year ago.

I’m going to have to ask the identical question that Jack did.

I despise those automobiles because they constantly appear to “barf” coolant after a run.

I’m assuming there isn’t a catch can or an overflow tank in there.

on May 27, 2008 It does, in fact, have an overflow tank with a sealer cap and a pressurizer, which is pressurized.

Jjoshx99 Introducing a New Reader 10:47 a.m.

It turned out to be a fracture in the radiator, which caused the car to begin dripping immediately after it was switched off.

on May 27, 2008 Now, I believe you should take it for a short drive, crack open the bonnet, and keep an eye out for a drop.

On the other hand, given that it’s British, isn’t it expected to leak something?

As long as the cables are not spewing smoke, everything is OK.

I’m having the exact same problem in my car.

This happened to my girlfriend’s ’93 900S over the weekend.

Since then, not a single drop has been lost.

JayDorkPosted on 5/18/10 at 2:29 p.m.

Nope, I didn’t come across any evident problems.

The overflow cap performs admirably (I have a pressurized reservoir anyway, no rad cap, like a 944.) I did had to repair a few of faulty hoses, but they weren’t too terrible over the area where I’d periodically come across standing water.

kb58Reader5/18/10 4:46 p.m.

That actually happened to me.

NGTDHalfDork 18th of May, 2010, 8:34 p.m.

It appears to be emanating from the water pump itself.

This happened lately with the Trooper’s water pump.

When I woke up in the morning, there would be a 4 or 5 inch puddle in the garage.

I’ve also seen hoses behave in this manner.

Screw type clamps must be retorqued, but spring and Oetiker type clamps need not.

The plastic tanks are sealed with a gasket, and then there are tabs on the radiator core that are crimped together to secure the tank to the radiator core.

A difficulty that VW had with hoses having a porous inner liner was that coolant would make its way through the liner and then follow the reinforcing threads to the end of the hose, where it would drop out.

The amusing part is that VW was aware of the problem for a while since the bad hoses were marked with a yellow paint dot and the good hoses were marked with a white paint dot.

I drove it for around 30 minutes before stopping it, and there was no leak.

It’s also coming from the back passenger side of the engine area, according to the witness. Doe this not imply that there is a leaky heater core? The back bottom side of the engine area, maybe below the automobile, has been edited. Bump?

Five Signs Your Water Pump Is Failing

HalfDork 6:35 p.m. on Friday, May 26th I took the Lotus out for a short cruise with the German Lotus Club this past weekend (about 100 kilometers). It was the first time I’d taken the vehicle out for a proper boot, and it had been generally cooperative. I returned to find a large puddle underneath the vehicle after parking it (in the warmth). Possibly a litre of coolant had leaked from some unseen source after I’d turned off the ignition. I’d never seen anything like it before. It did the same thing when I returned home after an hour of driving because I couldn’t find anything wrong with it immediately.

  1. Because the whole crossmember was moist below, it appears as though it all came out in one fell swoop!
  2. Nothing makes sense to me at this point.
  3. Type of spring that was originally used.
  4. ), I discovered a leak there.
  5. Verify that the water pump is working correctly.
  6. Use a pressure tester to pressurize the system and see how it works.
  7. Check to see whether it leaks when you turn the shaft from side to side.

nice: Something about the radiator cap, according to my intuition, but I can’t remember what the issue was.

JackSuperDork 10:10 p.m.

What percentage of the space was taken up by it?

– In the event that I completely fill my TR3 radiator (with no overflow tank), it will discharge coolant the first few times it is used.

There may be something else going on here.

on May 26, 2008 When the system is under strain, a crack in your radiator may get enlarged and seal itself shut.

It was about a year ago that I noticed coolant seeping from the engine’s front.

My inquiry is the same as Jack’s, and I must ask it as well.

I despise those automobiles because they constantly appear to “barf” coolant after a run, which is frustrating.

The catch can/overflow tank, if there is one, is not visible.

As a matter of fact, it is not equipped with a radiator cap since the customary method of topping up the coolant is to fill it up through the overflow tank.

When the automobile was switched off, the leak revealed out to be a crack in the radiator, which began to drip.

Many different factors might be the cause of the problem.

Jack the 38th TR’s As long as the wires are not emitting smoke, everything is OK.

I’m having the exact same problem in my car right now!

This happened last weekend with my girlfriend’s 1993 900S.

Not a drop of blood has been shed in the meanwhile.

JayDork, at 2:29 p.m.

Not a single clear issue was discovered.

The overflow lid closes tightly and effectively (I have a pressurized reservoir anyway, no rad cap, like a 944.) Even though I had to repair a few of frayed hoses, the situation wasn’t too terrible over the area where I’d periodically come across standing water.

18/10 4:46 p.m.

When I first noticed the leak, it was only after I had shut off the water for about a minute that it became apparent.

on May 18, 2010 – It’s now happening in my Passat.

This occurred lately with the Trooper’s water pump.

As soon as I walked into the garage, there would be a puddle about 4 or 5 inches in diameter.

Similarly, I’ve observed hoses behave in this manner.

Unlike spring and Oetiker clamps, which do not require retorquing, screw type clamps do.

Radiators made of plastic and metal have also been shown to accomplish this.

It is possible for a cold coolant leak to occur as a result of the gasket extruding away from its seam region over time.

It would need new hoses to correct this problem, not more clamp torquing.

I’m resurrecting an old post since my friend’s 2003 Dodge Caravan van is leaking coolant, and when I arrived, the vehicle was completely devoid of liquid.

If it is just water from when he is running the air conditioner, I am concerned, but he insists that it is coolant that is dripping from the car’s radiator.

It’s also coming from the back passenger side of the engine bay, according to the driver. It seems to imply, then, that the heater core is leaking. The back lower side of the engine bay, and maybe underneath the car, has been revised to read: Bump?

Overheating

A water pump that is dead or dying will be unable to circulate coolant through your vehicle’s engine, resulting in the engine overheating. The higher the temperature of the engine, the greater the likelihood of catastrophic damage, which can include a broken engine block as well as damage to the cylinders, pistons, and head gaskets. If your car is running excessively hot and/or if you notice steam coming out from below the hood, you should not continue driving it.

Coolant Leaks

It is typical to see coolant leaks from the water pump, which is a strong indication that it is time to replace the pump. A set of gaskets and seals hold the coolant in place inside the water pump, preventing it from leaking out. Once these components begin to wear out, become loose, or break, you may see radiator fluid flowing from the front of your vehicle toward the center. The color of the coolant is often green, orange, or red. It’s possible that the orange coolant contains rust.

Corroded Water Pump

Air leaking via a faulty pressure cap, non-compatible or unclean engine coolant, mineral buildup, and simply the passage of time can all cause your vehicle’s water pump to rust and break down. By opening the hood of your automobile, you may be able to notice corrosion or small holes on either the inside or outside of the fuel pump. Then it’s definitely time to repair your vehicle’s water pump, because a corroded or broken water pump cannot function properly.

Whining Noises

Your vehicle’s water pump can be corroded by a variety of factors including air leaking through the pressure cap, non-compatible or unclean engine coolant, mineral accumulation, and even the passage of time. By opening the hood of your automobile, you may be able to notice corrosion or small holes on each side of the fuel pump’s surface. A rusted or broken water pump in your car will not function properly, thus it is imperative that you have it replaced as soon as possible!

6 Signs You May Have a Bad Water Pump On Your Hands

Air leaking via a faulty pressure cap, non-compatible or unclean engine coolant, mineral buildup, and simply the passage of time can all cause your vehicle’s water pump to corrode and fail. If you open the hood of your automobile, you may notice corrosion or small holes on the outside of the fuel pump. Then it’s certainly time to repair your vehicle’s water pump, since a corroded or broken water pump will not function properly.

Unhealthy Circulation

The water pump circulates coolant through the radiator and around the engine, dissipating heat that has accumulated. Metal pieces that are rapidly moving and closely coupled create a great deal of friction and, as a result, heat. Overheating can result in components that are twisted, melted, fused together, shattered or otherwise structurally damaged (see illustration). The auxiliary drive belt, serpentine belt, or timing belt is typically used to operate the water pump, which is a pulley-driven device.

An impeller is located within the system, and it is responsible for keeping the system circulating.

In certain cases, impurities in the coolant might cause the impeller to actually wear down over time. Cavitation can also cause the impeller to deteriorate, resulting in the impeller’s inability to effectively pump coolant.

Leakage

Water pump failure can be detected by a noticeable coolant leak that is directed toward the front end of the car, among other things. If you leave your car parked overnight and observe an orange or green puddle on the ground (depending on the type of coolant you’re using), you should question the pump. However, don’t make the mistake of assuming that a lack of coolant on the ground means you don’t have a water pump leak. The oil dipstick should be checked if the coolant reservoir is running low but there is no obvious coolant leak.

Some Ford Duratec V6 engines, particularly those with a timing chain cover, are susceptible to coolant leaks inside.

Ick

Over time, a gradual leak will develop a buildup of muck around the pump’s internal components. Look for coolant trails running down from the pump, as well as a type of gelled coolant deposit around the outside of the vehicle. The presence of a “weep hole” beneath the pump’s shaft indicates that the internal seals have worn out, which is a solid symptom of a defective water pump, and that the pump is malfunctioning. You may also see a significant amount of rust surrounding the pump, as well as pitting (corrosion that causes microscopic holes in the metal) or cavitation (creation of cavities in a liquid) on the mounting surface if you examine carefully enough.

While this may not result in an instant failure, it will cause a low-coolant state (which is extremely dangerous) and enable the lubricant protecting the moving components within the pump to escape, both of which are extremely dangerous (which will ruin the bearing).

Noise

A slack auxiliary belt will make a whining noise that will become louder as the vehicle accelerates. It may be as easy as tightening the belt, changing the belt, or replacing the belt tensioner to correct the situation. If, on the other hand, you hear a grinding or growling sounds coming from the front of the engine, this suggests a faulty bearing. There are other bearings on the front of the engine that might fail, but in any event, you should take it to a technician as soon as possible to have the problem diagnosed and repaired as soon as possible.

Overheating

As soon as the pump fails, your engine will begin to overheat. If you haven’t detected any other symptoms of approaching failure, this is one to keep an eye out for. Add coolant immediately if the ” Low Coolant ” light illuminates, and check for a severe leak if the light does not illuminate. If the temperature gauge begins to climb over normal or if the temperature warning light illuminates, pull over and contact a tow truck for assistance. Once the water pumps fail, there is no safe period of time that you can keep the engine running without risking catastrophic damage to the engine.

However, without a pump to circulate the coolant, turning on the heater to cool down an engine with radiator problems would not be effective in this situation. The best course of action is to park it.

Steam

Smoke or steam coming from your radiator or from under the hood indicates that your engine is overheating and has likely already sustained significant damage to the internal combustion engine. Pull aside and ask for assistance as soon as possible. Keep your hands away from the engine until it has cooled down before digging about. You’ll be dealing with scalding-hot coolant and other potentially dangerous situations. Apart from being overheated, your cooling system is also under considerable pressure.

Near other cases, accessing a broken water pump may need extensive engine disassembly since it is positioned in the front of the engine, behind the fan, or squeezed close to a strut tower.

Prevent your engine from being damaged by paying close attention to the warning indications when they appear.

Consult with a trained specialist at your local NAPA AUTO PARTS shop for further information on whether you have a faulty water pump.
