HOW DO YOU KNOW WHEN YOUR WATER PUMP IS BAD?

1. Coolant leak at the front-center of your car

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 that 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.

2. Water pump pulley is loose and making whining sounds

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 that 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.


​3. Engine is overheating

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 that the engine temperature gauge is running 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.

4. Steam coming from your radiator

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. It's never a good idea to drive an overheating engine, so if you have to contact a tow truck to get the car home, this could save you significant money in the short and long term – it's going to be less expensive than replacing the engine entirely.
