Answered 43w ago Author has 175 answers and 41.1k answer views How do you know if your water pump is going bad? The following signs indicate that a water pump needs to be replaced: When a water pump is new, some seepage from the weep hole is normal as it takes about ten minutes of operation for the mechanical seal to properly seat itself. Cause: Contaminated coolant is the main cause of weep hole leakage. Solution: Thoroughly flush the cooling system before installing the new pump and refill the system with the correct vehicles coolant . Seepage drips or large coolant bleed marks on or around the mounting surface. Cause: Improper water pump installation or improper use of seals/gaskets . Solution: In case of recently installed new water pump : carefully remove, check and re-install the water pump. If the leakage is not the consequence of an improperly installed new water pump , the pump must be replaced immediately. Rust and corrosion on the surfaces of the water pump which makes the pump ineffective in moving the coolant . Cause: Contaminated coolant , non-compatible coolant or mixing coolants of different chemistries. Solution: Replace the water pump . Thoroughly flush the cooling system before installing the new pump and refill the system with the correct vehicle manufacturers recommended coolant. Inspect the pressure cap and replace if defective. With the engine off, check the condition of the bearing by looking for any side-to-side play at the shaft. Apply hand pressure; there should be no play at all. Cause: A misaligned belt causes excessive wear. An over-tensioned belt causes overload on the bearing, accelerating wear. A damaged mechanical seal allows coolant to leak through the bearings and wash away the lubricator. Solution: Replace the water pump and make su Continue reading >>
Symptoms Of A Bad Or Failing Water Pump
Common signs include coolant leaks at the front-center of the car, loose water pump pulley, overheating engine, and steam coming from the radiator. by a top-rated mechanic at your home or office In order to run cool on those hot summer days, your engine needs to have a consistent flow of coolant supplied from the radiator throughout the engine. The water pump is the primary component responsible for maintaining this flow. When it works properly, your car will maintain a consistent operating temperature, run smoothly, and take you anywhere you need to travel. When the water pump fails or is beginning to wear out, it can lead to complete engine failure. When the water cooled (as opposed to air cooled) engine was introduced, many automotive experts believed that the water pump circulating coolant through the engine block was just as critical to engine protection as oil. This philosophy holds true even as technology has improved over the years to create more efficient cooling systems in today's modern cars. Your cars water pump is the key to making the entire system work. It is an impeller pump and is usually buried under the timing belt cover on the side of the engine. The pump is operated by the engines drive belt as the belt turns, the pump turns. Blades on the pump force coolant to flow through the engine and back to the radiator to be cooled by a forced air cooling fan. Although the water pumps in most modern cars, trucks, and SUVs will last a long time, they are by no means indestructible. Like any other mechanical device, they will produce a few warning signs that they are wearing out , so that car owners can contact a local ASE certified mechanic to replace the water pump before additional engine components are damaged. Here are some common symptoms that hint towar Continue reading >>
3 Parts That Commonly Fail After The Radiator Goes Bad - Meineke
3 PARTS THAT COMMONLY FAIL AFTER THE RADIATOR GOES BAD 3 Parts That Commonly Fail After the Radiator Goes Bad As you look at your vehicle's engine bay, you may find yourself wondering, "How does a radiator work?" The radiator in your car actively dissipates heat that builds up in the cooling system. As coolant runs through the radiator, the walls of the internal passageways start to develop a thick layer of scale. Debris running through the cooling system may also cause a blockage to develop in those tight radiator tubes. When this happens, the radiator's cooling abilities drastically decrease. When one component fails to work properly, other parts throughout the cooling system also run the risk of failure. The three parts that commonly cease working after the radiator goes bad are the thermostat, water pump, and heater core. Here is a breakdown of what each of these parts do and what happens when they fail. Each engine size and configuration has a specific ideal operating temperature. To control the temperature, the thermostat sits at the end of the bottom radiator hose and directly regulates the flow of water through the cooling system. When the engine reaches ideal operating temperature, the thermostat opens and allows the cooling system to flow freely. When the radiator stops working correctly, too much pressure is put on the thermostat, often causing it to stop working. When the thermostat fails, the valve inside gets stuck either open or closed. With a closed thermostat, your engine will immediately start to overheat. You can tell the thermostat is stuck closed by carefully touching the radiator hoses. The top one will feel hot, yet the bottom hose will remain cold. When the thermostat sticks open, the engine will never reach operating temperature, which negative Continue reading >>
Water Pump Failure Points
Leaks are the most common sign of water pump failure, but what type of seepage are you seeing and what does it mean? A coolant leak coming from the weep hole is a sign of water pump bearing or seal failure. This weep hole often resides between seals that separate the oil side from the coolant side. A small amount of dry seepage around the hole can be considered normal, but its only a matter of time before a seal becomes defective and the seep turns into a drip. A coolant leak into the front cover area, connected to the oil sump, means the outer O-ring has failed. This could mimic a head gasket leak. Adding cold coolant to an overheated engine can cause thermal shock and create a seal leak even in a new water pump. Starting an engine during a water pump replacement before adding coolant could have the same effect. Look for a crack across either the seal face or the mating ring as evidence. Allow an overheated engine to sit and cool before adding coolant. Then, restart the engine and allow it to run while slowly adding the remainder. Abrasive particles accelerate water pump seal wear. For example, systems that are not properly pressurized allow air to enter and foster the build up of rust. Or, if water with a high mineral content is added to the system and is heated, it will begin to form deposits that will accumulate and cause passage restrictions. Both of these are harmful to seals. Although rust is difficult to remove, it should be flushed from the system as thoroughly as possible before the old water pump is removed. When replacing the pump, O-rings need to be lubricated with either oil or coolant. Do not use silicone or other sealants that can block the weep hole. Cavitation is the formation of vapor cavities in a liquid as a result of forces acting upon the liquid, Continue reading >>
How To Tell If My Water Pump Is Bad
Having a bad water pump can cause a lot of problems with your vehicle. If youre asking how to tell if my water pump is bad, then youre probably already experiencing some of the problems associated with it. The water pump in your car is the motive force behind the cooling system. Every vehicle on the road today is equipped with a radiator at the front of the car to cool the antifreeze in your vehicle. In most vehicles, the water pump draws the coolant out of the radiator and pushes it into your engine block, cylinder heads and any other components that need to be cooled like an oil cooler, the throttle body or turbocharger if your engine is equipped. From there, your engine coolant is pushed, still by the pressure of your engines water pump, back into your radiator to be cooled and start the journey again. If the water pump in your car fails, the motive force for the coolant quickly goes away allowing the water in the engine to heat up very quickly and your engine to overheat, possibly causing damage. There are really 3 main ways your water pump can fail, catastrophic failure, bearing failure or seal failure. First, catastrophic failure to your water pump is possible but unlikely. This would include things like the actual pump impeller coming off the shaft, pump blades chipping or falling off or other damage that would cause water to stop flowing. Although unlikely, this type of water pump failure is the most dangerous. Catastrophic failure of your water pump will cause either a complete or partial loss of coolant flow and rapid overheating. If this happens to your vehicle, it may be accompanied by engine noise or a broken engine belt, but will definitely result in your engine temperature gauge rising quickly. If this happens to you, quickly pull over and shut down your Continue reading >>
How Long Does A Water Pump Last?
NEXT Small parts on a car's engine are often easy to overlook, but those components are often some of the most important to keep everything running properly. In the case of keeping your engine cool, the water pump is an effective and integral part of the process. But how long can you expect it to last? The water pump endures constant use inside an engine and allows the engine to endure the intense heat that internal combustion produces. When your engine is on, the water pump circulates coolant, or antifreeze, in the cylinder head and the engine block to cool the engine down. After the coolant passes through the engine it's sent back into the radiator to be cooled before entering the engine again. When it comes to water pump longevity, they actually tend to last a long time. It's recommended that your engine's water pump be replaced when the timing belt is serviced. Water pumps are driven by the timing belt, or an accessory drive belt that spins a pulley outside of the pump which turns the internal impeller. On different makes and models of cars, these belts can last anywhere between 60,000 and 90,000 miles (96,561 to 144,841 kilometers), so you can expect your water pump to last about that long, too. Of course, some water pumps may not last quite that long, but manufacturers make efforts to ensure water pumps last a long time due to negative effects on the engine if they fail. To avoid running into the problem of a failed water pump, there are a couple warning signs that you can look for. The first is if coolant is leaking around the water pump. Weep holes located on the casing of the water pump will leak coolant when the pump is failing. The second red flag is if the water pump is making more noise than usual. This may be from a defective impeller or an impeller that's Continue reading >>
Water Pump Failure-what Are The Symptoms
Although the water pump in most vehicles will last a long time, they are by no means indestructible. Like any other mechanical device, they will produce a few warning signs that they are wearing out. To start with, Water Pump Failure is extremely hard to diagnose. This info is only meant to help reduce the time in finding the actual problem. Water Pump Failure-What are the Symptoms. Your cars water pump is the key to keeping the entire system cool. Usually one of the drive belts on your engine is what turns your water pump. Impeller blades on the pump force the coolant to flow through the engine and back to the radiator. Now a forced air cooling fan does its magic. The water pump is the primary component responsible for maintaining this flow. Consequently if it works properly, your car will maintain a consistent operating temperature. When the water pump fails or is beginning to wear out, it can lead to complete engine failure. When there is a problem with the flow of operation and your engine starts to get hot, it is time to investigate if your cars water pump is failing. If the water pump shows signs of weakness or fails completely, coolant will not flow through the cooling system correctly. If coolant does not flow, engine temperatures rise and it begins to overheat. Here are some common symptoms that hint towards having a water pump failure: If the cooling system is operating correctly, the temperature should remain stable throughout a range of vehicle operating conditions. However, if your temperature gauge starts bouncing between normal and hot, this could indicate a bad water pump. Here is a list of other things that can fail to mirror these same symptoms: The water pump is comprised of multiple gaskets and seals that keep coolant contained. This ensure that a c Continue reading >>
How To Tell If Your Car's Water Pump Is Going Out Explained
Home Articles Symptoms of a Bad Water Pump You will notice coolant leaking from the front of your car or hear a strange noise from your engine. The water pump in your car's engine is designed to circulate coolant through the cylinder heads and main block to keep the engine from overheating while in operation. This pump is driven by a main serpentine belt or timing belt which rotates an impeller that is submerged in coolant in the front part of the engine. When the engine is cold and first starts up coolant is circulated within the block while bypassing the radiator allowing the engine to warm up to operating temperatures. This coolant flow control is the job of the thermostat which blocks off the upper or lower radiator hose which controls when the coolant circulates. The water pump is designed with a weep hole to allow coolant to leak from its housing before it can reach the shaft bearing which will cause the shaft to lock up and stop turning. If this shaft locks up it will cause the serpentine belt to get thrown off which will render the car useless. It is typical for the pump shaft seals to leak while the engine is running and then stop leaking once the engine has been shut off and the pump stops turning. When the coolant level inside the engine diminishes it will overheat which can cause the block or cylinder heads to crack. It is difficult to replace the water pump seal by itself which is why in most cases the water pump must be replaced . To replace the pump seal a hydraulic press must be used which will cost more than a new pump. Because the engine is depended of its circulating coolant, if the operation of the pump fails to push coolant throughout the radiator, block and cylinder heads it will cause the engine to overheat . This will be noticed by the driver of Continue reading >>
Symptoms Of A Bad Or Failing Water Pump (auxiliary)
Symptoms of a Bad or Failing Water Pump (Auxiliary) Symptoms of a Bad or Failing Water Pump (Auxiliary) Common signs include no warm air or fluctuating heat coming from the heater, the window defroster not working, and high pitched buzzing sounds. Many of today's modern cars utilize a standard water pump to keep their engines at a consistent operating temperature. Their single pump system circulates coolant from the radiator, through the engine block, to a heater core, and then back to the radiator. However, it is common for many vehicles, especially heavy duty pick-ups to have an auxiliary water pump that will expedite the process. An auxiliary water pump is different than a single water pump in that it is an electrically controlled motor. Its primary use is circulating water by way of a bypass hose from the main coolant lines to a heater core that is used to collect heat and distribute warm air into your vehicle when the heater is turned on. A failing auxiliary water pump will not typically keep you from driving your vehicle, it can definitely affect your comfort in the winter and in severe cold conditions. If not repaired or replaced, it could be dangerous to drive if the pump is failing or has completely failed. There are a few common warning signs that you should be aware of that might indicate a problem with your auxiliary water pump exists and that it has reached the end of its service life . Since it is the primary job of an auxiliary water pump to supply hot coolant to the heater core, it seems obvious that the first symptom of a problem with this component would be no hot air blowing from the heater . The auxiliary water pump moves hot water or coolant that has recently circulated through the engine block to the heater core. However, when the pump is not work Continue reading >>
Diagnosing And Resolving Water Pump Problems | Gates Europe
Guidelines for replacing water pumps in 13 easy steps Appearance: The pump's internal mechanical seal seals the shaft towards the cooling circuit, protecting the bearings by preventing coolant from passing into the bearing assembly. When a water pump is new, some seepage from the weep hole is normal as it takes about ten minutes of operation for the mechanical seal to properly seat itself (break-in period). More pronounced seepage and drips from the weep hole after this break-in period or a large coolant bleed mark around the weep hole are abnormal and indicate impending water pump failure. Cause: Contaminated coolant is the main cause of weep hole leakage. Solution: Thoroughly flush the cooling system before installing the new pump and refill the system with the correct vehicle manufacturers recommended coolant. Never dry run a water pump, not even for a few seconds. Dry running of the pump ruins its mechanical seal. Replacing the water pump is critical for a complete overhaul.

Appearance: Seepage, drips or large coolant bleed marks on or around the mounting surface or on the housing. Cause: Improper water pump installation or improper use of seals/gaskets or sealant. Solution: In case of a recently installed new water pump: carefully remove, check and re-install the water pump . Strictly follow the torque specifications. Make sure seals/gaskets are in perfect condition and are installed correctly. When sealant is prescribed, clean the rims of the part and the mounting surface and apply new sealant evenly along the edge of the part. If the leakage is not the consequence of an improperly installed new water pump, the pump must be replaced immediately. Appearan Continue reading >>
How To Tell If A Car's Water Pump Needs Replacement
How to Tell if a Car's Water Pump Needs Replacement Your car's water pump is an important part of your vehicle. It is the part that continually pumps coolant to your vehicle's engine so that it doesn't overheat. A leak or a faulty bearing can cause serious damage to your car's engine. Puddles of coolant underneath your vehicle or high temperature readings may be signs that your water pump needs replacing. Let your car sit overnight, parked in a garage with a clean concrete floor. If it's not possible to park it inside on a clean concrete surface, place a piece of light-colored cardboard underneath your car directly under the motor. Be mindful that water pumps are more likely to leak while the vehicle engine is running, so this is a poor reference for finding a leak. Examine the cardboard the next morning. If it appears to be wet from coolant, you have a leak somewhere, possibly in your water pump, but other sources of leaking coolant could be radiator hoses, heater hoses, freeze plugs, gaskets, or the radiator itself. To narrow the search down, try to place the cardboard directly underneath the water pump itself. If you notice green liquid on the cardboard, it's antifreeze. This means you have a coolant leak somewhere. Check the water pump pulley. Find the round part at the front of your water pump that the belt is around. Attempt to rock the pulley back and forth. If it seems to be loose, it may be time to replace it, because the bearing is going bad. Listen to your car. Start your car's engine with the hood up. If you hear a low-pitched grinding noise, it may indicate that your water pump bearing is going bad. You can often hear it plainly if it's gone bad. You also have similar bearings in your AC compressor, power steering pump, and alternator, so you need to be ab Continue reading >>
What Causes A Water Pump On A Car To Go Bad?????
What causes a water pump on a car to go bad????? What causes a water pump on a car to go bad????? and are they a pain to change by yourself????? Update: It's a saturn Sc1 my girlfriends water pump went and now it's time to fix it. Are you sure you want to delete this answer? Best Answer: Bearing siezes/ Housing leaks/ Seals wear out. All do to use, expanding/contracting due to heat and cool down, and time also. Just a side note for Bryan K a car being FWD or RWD has no bearing on how much room you have for the waterpump or vice versa. This is a generalized statement that holds no truth. I'll give you one example that makes that statement false : when replacing a timing belt/water pump 96-01 Audi A4 1.8t 4cyl the entire front bumper and support must be removed in order to gain access to the timing belt and water pump. However this method is true for both FWD/AWD models. 99.5 to 2004 volkswagens have the same 1.8t engine but they are not longitudinally orientated the water pump and timing belt can be accessed fairly easy a lot less labor than the audi and the jetta is also available in FWD and AWD. Before someone contradicts the AWD jetta look up 4motion volkswagens. There are not alot in the states but they exist. Thanks for allowing me to throw inmy two cents in correcting generalized truths that are not true. the corrosion is the main cause, corrosion is caused by using water coming by the faucet, that water came with some minerals and stuff and the engine at high temp activate those minerals and react causing that brown water (acid water) so the best way is adding a nice mixture of coolant and destilated water is the best but if you dont have that water at hand use some radiator coolant aditive, it will neutralize the effects of the regular water coming from the fauc Continue reading >>
Water Pump Failure Symptoms - How To Tell If Water Pump Is Bad? | Youramazingcar
In order to comprehend the indications of water pump disappointment, you must have an essential comprehension of water pump working and configuration. What does the auto water pump do? It consistently flows water around the motor which diverts the warmth produced by it. In the event that it were not for the water stream kept up by the pump, the motor would warmth up considerably at high RPMs and inevitably breakdown. In cutting edge autos, the stream rate of water pump changes according to the estimation of the motor RPM. As the motor moves over to higher RPM values, the water stream rate increments at the same time. This is attained to with the utilization of an indoor regulator. The thought process power for the working of a water pump is supplied by the motor itself, through a various rib belt joined to the crankshaft. The principle working parts of a water pump are its primary shaft, impeller, sealant, rib and gasket. Every one of these parts are housed together and driven by the numerous rib belt. Any of the flawed water pump manifestations can be followed to a breaking down of any of these parts. Give us a chance to now take a gander at the fizzled water pump side effects in the following area. There are numerous pointers that insight towards auto water pump issues. Here are the most important and conspicuous broken water pump indications. Motor overheating is a standout amongst the most conspicuous indications of water pump disappointment. At the point when an interior issue hampers the working of a water pump, it doesnt cool the motor that effectively. Therefore, the motor temperature ascends at high RPMs and may bring about major harm. In the event that you recognize ceaseless overheating, odds are that your auto is experiencing water pump disappointment. Over Continue reading >>
Water Pump Failure: Causes And Prevention Tips From Gates
Water Pump Failure: Causes and Prevention Tips from Gates Gates offers a comprehensive note on the common causes of water pump failure and tips on future failure prevention. Various factors other than just the quality of the water pump can cause its failure and offers an exhaustive note on the root causes and corrective measures. The average water pump handles 1.7m litres of coolant in 4 years/ 60,000 miles. If it fails sooner and is replaced without proper investigation, the new pump is likely to have an even shorter lifespan. Correct diagnosis before replacement is important to avoid more problems in the future. Most warranty returns are due to errors in the installation process. In fact, a faulty mechanical seal as a result of installation error is the most common cause of premature water pump failure. To keep the pumps rotating seal faces from overheating and failing, the mechanical seal must be constantly lubricated by a coolant. Dry running even for a few seconds can ruin the seal, causing coolant leakage. A new water pump should never be checked for free rotation when dry. It should be put in a coolant-filled reservoir before fitment or, run by hand a few times after coolant refill and before starting the engine. This can cause an improper seating of the water pump or even damage some sensitive components such as seals, leading to coolant leakage. Old gaskets and seals should be replaced by new ones and sealant should only be applied if recommended by the manufacturer. Gates provides gaskets as part of the kit, where required. Sealants should not be applied on pumps with gaskets or seals. Too much sealant compromises the correct installation and will break off within the cooling circuit and contaminate it, so correct usage, where needed is recommended. Using a c Continue reading >>
Symptoms Of A Bad Water Pump
Between all its moving parts and the fact that it burns fuel, its no surprise your engine gets hot when its running. This is where cooling system comes into play, and your water pump plays a key role in it. If the water pump fails, youll want to get it diagnosed by a mechanic quickly, as you run the risk of your engine overheating . Your cars water pump pushes coolant through the engine, hoses and radiator in order to keep the engine at an optimal temperature while its running. The coolant absorbs heat created during the combustion process in the engine and then releases it while traveling through the radiator. The pump uses centrifugal force to send the coolant out and suction to pull it back in. The water pump is usually mounted on the front of the engine and driven by the serpentine belt , or timing belt. A mounting gasket is used to form a seal between the water pump and the engine block. Inside the water pump is an impeller a centrifugal fan thats designed to move water through your engine and cooling system. This impeller is attached to a shaft thats supported by a bearing assembly. When the serpentine belt turns the water pump pulley, the impeller spins and pumps your coolant. Water pumps typically fail due to a broken impeller, bad bearing assembly or faulty shaft seal. These issues are usually caused by one of the following: Time and mileage: Water pumps dont last forever. In some cases, the pump may just wear out. This may be accelerated by a poor pump design. Corrosion: Dirty or contaminated coolant can cause the pump shaft seal to fail prematurely. It can also eat away at the impeller blades or the impeller shaft. Running dry: The water pump is lubricated by coolant. If the pump is run dry due to a low coolant level, the shaft seal may get ruined. A faulty Continue reading >>
