Your water pump bearing is either a sealed bearing or lubricated simply by the coolant so it has the opportunity to wear out much more quickly than the oil lubricated bearings in your engine. A worn bearing in your water pump will usually manifest itself as pump noise as it will allow the pump pulley to wobble as it rotates. In extreme cases, you may be able to see the pump pulley or belt wobbling as your engine idles. With your engine off and cold, you can try grabbing the water pump pulley and wiggle it to see if you can feel bearing movement.
If you do, the best option is to simply replace your water pump. The last way your water pump can fail is a seal failure. This can include the shaft seal or the water pump seal to the block.
The shaft seal can fail due to wear or a bad bearing and the block seal can fail due to overheating, improper installation or simply old age. If the shaft seal is worn and leaking in your water pump, the best course of action is to simply replace the pump. The area around your water pump is due to significant amounts of stress due to the heating and cooling of your engine in that area and can be prone to cracking.
A crack in this area will leak small amounts of coolant, especially when warm, and can easily be confused for a water pump seal leak. If you do discover a cracked block near your water pump, you can quickly and easily seal the leak using BlueDevil Radiator and Block Sealer. BlueDevil Radiator and Block Sealer is specially formulated to seek out cracks in your radiator and block and form a seal and stop the leak.
BlueDevil Radiator and Block Sealer seals the leak in your block without clogging or harming any other area of your cooling system! You can purchase BlueDevil Radiator and Block Sealer at any of our partnering local auto parts stores like:. Feel free to contact our technical support line at with any other questions.
Unfortunately, we do not manufacture a product intended to stop water pump leaks. Replacing the water pump may be your best option.
Hey guys… I have a ford ranger. My car is over heating but my coolant is full and my radiator is dry. I can tell if the water pump is bad or just a leak.
Thanks for your question about your Ford Ranger. If your coolant reservoir is full but your radiator is not then you have a leak somewhere in your system. The leak point will let coolant out when the system is hot then it is allowing air to get pulled back into the system as it cools rather than pulling coolant from the reservoir into the radiator. The best way to find leaks like this is the pressure test your system and watch for leaks when the system is at or slightly over the pressure the radiator cap releases at.
Two days ago my car overheated but went back down to the middle. Got home and checked there was no water in the reserve. Filled it with water and when I got back from store 5 mile round trip the reserve was empty again.
Can you tell me why? If it is emptying that quickly, it may indicate that you are losing water through a leak point somewhere throughout the cooling system.
I then let it cool down to check the problem an the water tank was empty so then I started filling up the antifreeze tank an noticed all the coolent started draining out from under the car what can the problem be? Thank you for asking about your Audi A6. Based on your description, your best bet may be to have your vehicle looked at by a certified ASE mechanic.
A split or broken hose, hole in the radiator, leaks in the water pump, heater core, or engine freeze plugs can also allow coolant to escape. When driving car starts lurching. Any ideas in the problem at hand or any possible solutions?
Thank you. Thank you for asking about your Chrysler Aspen. Is the vehicle overheating at all? The most common cause for this type of issue would be a faulty radiator cap or a loose connection of where the hose clamps to the radiator.
You can test to see if this is the case by removing the radiator cap when the vehicle is cold and checking for corrosion. No smell while idling in Park. Also- car smells hot, but temperature gauge remains normal. Has been suggested that it could be a bad water pump. Thank you for asking about your Chevy Cruze. Depending on the manufacturer, it is typically recommended to have the water pump replaced every 90, miles. Hello I have ford taurus SE 3. I had a minor front accident, which broke front bumper grill and shutter grill and the radiator is fine.
One mechanic checked it and told me that the water pump is effected and failing slowly. The car is fine but i have the doubt about what mechanic is saying Please guide Bundle of thanks. Thank you for asking about your Ford Taurus. It is possible that the mechanic could have inspected the water pump and found a seep or some kind of build up, leading him to believe the water pump was starting to go.
Based on your description, it would be a good idea to have the water pump replaced to prevent further issues from happening down the road. Thanks Blue devil pro for previous reply. Can you please guide about octane also. I was previously using 95 octane, now i am using 91 octane and tires are not spinning. Thanks for your question about octane.
It is possible that using lower octane is reducing the amount of power your car can make. The higher the octane rating of the fuel, the more resistant it will be to knocking or preignition. If using a lower octane fuel is causing knocking, your motor will sense that and reduce the engine timing to compensate for the lower octane fuel.
Reduced timing means less power and could be what is causing your car to not have enough power to spin the wheels. I have a 08 Impala 3. I was told my water pump is leaking coolant. I was wondering if you a product that would repair the leak? Thank you for asking about your Chevy Impala. Having the water pump replaced may be your best option. Thank you for asking about your Ford Focus. How many miles are on the vehicle?
Typically, it is recommended to replace the water pump at 90, — , mile intervals. If it has reached or surpassed that mileage, it would be a good idea to replace the water pump. If the issue continues, you may want to bring it to a shop for a proper diagnosis. I have a Ford Taurus I was just wondering it started making a loud screeching sound could that be the cause of a water pump going bad If I put Blue Devil in my Ford Taurus water pump would that stop the screeching sound.
Unfortunately, we do not manufacture a product intended to stop leaks from the water pump. I have a pontiac g6 it overheats quickly and causes the car to not have acceleration i changed the thermostat and the top radiator hose as well due to a hole hopefully its nothing serious as blown head.
Thank you for asking about your Pontiac g6. Your next step may be to have the water pump replaced. Toyota sienna mile. Filled up Antifreeze to top drive 2 mile car start to heat again. I cannot see no leaks. Water pump fill cold pump coming out from coolent reserve tank seems as it going away but the small pipe to the engine is way to hot.
Thank you for asking about your Toyota Sienna. Based on your description, it is possible that a faulty water pump is the reason your vehicle is overheating. If the flow in the cooing system is being restricted, and overheating that quickly, it is most likely time for a water pump replacement. You can also check to see that the thermostat is functioning properly and opening up as it should.
A faulty thermostat could also cause the vehicle to overheat, as you have described. Thanks for your question about your car overheating. If your car is overheating, but not all the time it could be caused by a clog in your radiator or a problem with your water pump. Similarly, a low cooling system level can cause overheating if the ambient temperature fluctuates drastically from day to day or the distance you travel each trip fluctuates also.
Hi i have a Lexus i recently had a radiator leak so i replaced radiator still it was running hot so changed thermostat. Still my car is running rough But the gauges are normal staing in the middle. But after driving a short distance i can smell my car is very hot and when i open hood the top and lower hoses are very hot and feels like they are going to explode.
Thank you for asking about your Lexus. Do you happen to know what caused the radiator to start leaking? Was the cooling system building up a lot of pressure? You mentioned the car was running rough, also. Have you noticed any problems with engine power? So I have an 04 2. Coolant, checked all the hoses and the water pump. Sometimes it will go back down in temperature if I have a straight drive with no stops. Thank you for asking about your Mitsubishi Eclipse. Depending on how many miles are on the vehicle, it may be time for a water pump replacement, as it is typically recommended every 90, miles or so to have this service performed.
Another possibility is having an air pocket trapped in the system. You may notice a bubbling or a boiling over if that is the case. Have you attempted bleeding the system? It usually will take around 15 — 20 minutes.
You should eventually notice the coolant stops bubbling up every so often. As it bubbles up the coolant level will drop and you should top it off.
I have a Audi A6 Quattro 2. It seems to leak coolant on occasion while parked after driving. It does not leak everytime and the leak seems more serious at times. Does this seem like it could be the pump, or possibly the seal?
Thank you for asking about your Audi A6 Quattro. Based on your description, it seems more likely that a hose connection is loose than something to do with the water pump. If the leak was water pump related, that would have been detected at the time the vehicle was looked at. Are you noticing any other symptoms such as overheating? I have a Ford Ranger, 2. It was overheating, I replaced the radiator, thermostat, heat sensor, HCL valve and flushed the heater core. The vehicle no longer overheats, but I cannot get the heat to turn on.
When I check the water hoses, the one on top gets a little warm, the one on the bottom stays cold. Also neither of the hoses connected to the heater core are that hot. Is it possible that the water pump is going bad?
It is possible that your water pump is starting to go out and not able to push water through your heater core. If that was the case you would probably have a large temperature difference across your radiator as well.
I have a Jeep Liberty Renegade, in August I noticed a trickle of anti-freeze like fluid running down the side and underneath the engine creating a spot on our garage floor. After a day or two of being parked a small drip was taking place. So far the radiator and all connections have been checked by a mechanic and given the ok. No overheating.
Any thoughts? Thank you for asking about your Jeep Liberty Renegade. Typically, when the water pump starts not functioning properly, you would have an issue with overheating and more than likely, notice antifreeze leaking from the weep hole. Also, the fact that your heater is functioning properly indicates that you are getting proper flow, which means the water pump is circulating and functioning as it should.
I have a toyota camary 2. I have to wait for the radiator to cool. Thank you for asking about your Toyota Camry. Are you noticing any other symptoms, besides the loss of coolant? It seems strange that you are not noticing a rise in temperature, even with the extreme loss of coolant you are experiencing.
Thank you for asking about your Hyundai Santa Fe. Has the water pump ever been replaced? It is generally recommended that the water pump be replaced every 90, miles, depending on the car manufacturer.
A failing water pump, or a water pump that has gone bad, would usually result in overheating. Based on your description, it would be best to have a certified ASE mechanic take a look at the vehicle and give you a proper diagnosis. I am having a WagonR of model … recently I got serviced it with a mechanic.. Thank you for asking about your Suzuki Wagon R. Typically, depending on the car manufacturer, it is recommended to have the water pump replaced at 90, mile intervals.
Are you aware of the mechanic bleeding the system after refilling the coolant? Thank you for asking about your Jeep Grand Cherokee. Based on your description, it does sound like the vehicle is shutting down due to a lack of flow. The lack of flow could be caused from a faulty thermostat, perhaps one that is stuck closed. You can check the thermostat by placing it in boiling water and making sure it is opening up at the correct temperature.
I have a dodge Dakota 4. It still heats up. What can it be? I thought of every option possible but still heats up. Do you think the water pump was a bad one? What you think it may be? Thank You. Thank you for asking about your Dodge Dakota. Based on your description, there may be some kind of restriction elsewhere in the cooling system.
A cooling system flush would be recommended at this point. Are you noticing any other symptoms? I did a flush before I install everything, everything was good before I changed the fan and radiator.
Thank you for the response. The follow up. After the new water pump and another flush. Idle between degrees with the ac on. The water pump was a major step up from the stock one. Thank you guys for all the info. I have a Dodge Ram Conversion Van in which the Serpentine belt broke due to the tensioner going bad.
Pull over, call a tow truck and get your vehicle diagnosed quickly. When a water pump completely fails, it is no longer able to move coolant through the engine; this causes it to overheat. If you see steam, pull over immediately and call your mechanic for assistance — continuing to drive with an overheated engine can damage it to the point that it will need to be completely replaced.
If you see any of the five signs above, call your local mechanic for an inspection of your vehicle. Being proactive is a major part of car care. In general, proactive and preventative maintenance is a much more affordable part of car ownership than repairs. By catching the problem early, you can save time, money and hassle. Read More. As the temperature Find Your Local Shop. The pump is made up of several different gaskets and seals that will eventually dry out, crack or break. When this happens, the coolant will leak from the pump.
If you see a puddle of orange, green, pink or blue liquid when pulling out of your driveway after your car has been sitting for a while, bring your car into a repair shop as soon as possible. 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 improves over the years to create more efficient cooling systems in today's modern cars. It is an impeller pump and is usually buried under the timing belt cover on the side of the engine.
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 of wearing out, so that car owners can contact a local ASE certified mechanic to replace the water pump before additional engine components are damaged.
The water pump is comprised of multiple gaskets and seals that keep coolant contained and ensure that consistent flow of coolant is delivered from the radiator to the engine.
Eventually, these gaskets and seals will wear out, dry up, crack or break entirely. When this happens, coolant will leak from the water pump and drop to the ground, typically in the front of your car and in the center of the motor's location.
If you notice there is a leak of coolant which will appear to be green or sometimes red in color under the center of your car, truck or SUV, contact a professional mechanic to inspect this problem.
More often than not, it's a leak from the water pump that can be repaired before it gets worse. Gradual leakage over time will cause different minerals to build up around the pump. The wrong coolant will also cause deposit-buildup inside the pump, which slows the ideal process of engine cooling. In addition to these signs of wear, you may also notice small holes from corrosion in the metal, or cavitation — vapor bubbles in the coolant liquid that collapse with enough force to create cavities on the mounting surface.
Should you notice these symptoms, replacement of the pump should be sought out immediately. From time to time you might hear a high pitched sound that comes from the front of the motor.
This is typically caused by a loose belt that creates a harmonic buzzing or whining sound as it circulates. The loose belt is commonly caused by a pulley that has become loose or that the bearings that operate the water pump assembly are wearing out. Once the bearings fail inside the water pump, it means the unit cannot be repaired and will need to be replaced entirely. If you notice there is a loud whining sound coming from the front of your motor that increases in volume as you accelerate, contact a mechanic as soon as possible to inspect your vehicle.
When the water pump fails completely, it will not be able to circulate coolant through the engine block. This results in an overheating situation and if not repaired or replaced quickly, can cause additional engine damage like cracked cylinder heads, pushed head gaskets, or burnt pistons.
If you notice the engine temperature gauge runs hot on a frequent basis, it's more likely than not a problem with the water pump. You should contact a mechanic to inspect this problem and replace the water pump if needed.
Finally, if you notice steam is coming from the front of your motor as you drive or come to a stop, it is an instant sign of an overheated engine. As discussed above, an engine will maintain a consistent temperature when the water pump works correctly and circulates water to a functioning radiator.
If you notice steam coming from the front of your motor, you should pull over to a safe area and contact a mechanic as soon as possible.
