However, one of the more common mechanical parts that can fail sooner than later is the water pump pulley. The water pump on any vehicle uses a system of belts and pulleys to operate. Most modern cars, trucks, and SUVs use a serpentine belt which routes around the engine, turning pulleys, which operate various accessories including AC systems, and alternators. When the water pump pulley wears out, the pulley will refuse to turn, which results in a water pump that doesn't efficiently circulate water throughout the engine.

In order to reduce the potential of having your engine overheat or other major mechanical problems developing, having the water pump pulley replaced before it breaks completely is recommended by all mechanics and automotive manufacturers. There are a few warning signs that you can be aware of that will indicate a problem with your water pump pulley exists. The most obvious sign that a problem exists with your water pump pulley is if it's physically damaged.

There are multiple ways this metal component can be damaged, including having an incorrect sized or improperly adjusted water pump belt installed, vehicle accidents or problems with the internal bearings that allow the pulley to spin.

If one of these technicians tells you that your water pump pulley looks damaged, don't wait for it to fix itself.

Another common symptom of a damaged water pump pulley is when you or someone else looking under your vehicle's hood notices extensive wear on the belts that come in contact with the pulley. If the pulley is loose it can cause the water pump belts to shake and develop more heat. When this occurs, the belts can crack or literally shred; as most of these belts are made out of rubber and nylon cords for strength.

If it's discovered that the water pump or serpentine belt is wearing out sooner than it should, it's likely a problem with the water pump pulley. Most of the time, the problem with a water pump pulley is not the pulley itself, but the bearings inside the pulley. When the bearings wear out, it will create a metal-to-metal grinding sound which is commonly due to lack of lubrication or a faulty bearing. This sound is very difficult to notice while driving, however if you can hear a grinding sound while the car is idling, pull the car over, pop the hood of your engine and listen closely to the front of your motor.

If you can hear a constant grinding sound, close the hood and drive home safely. Contact a mechanic to inspect this problem and have them replace the water pump pulley as a precaution.

If your engine temperature is running in the "red zone" on your dashboard temperature register, that is an instant sign that a problem exists with the coolant system.

One common misdiagnosis that unexperienced mechanics will make is assuming that the water pump is broken, when in fact it's the water pump pulley that has ceased to function correctly. Anytime you hear or recognize any of the above warning signs, make sure to contact an experienced ASE certified mechanic to inspect, road test, diagnose, and repair your car, before it causes additional damage.

Replacing a water pump pulley can be rather inexpensive, so be proactive and contact YourMechanic as soon as you notice any of these warning signs. The most popular service booked by readers of this article is Vehicle Engine Cooling Inspection.

How big of a job is it to replace that? I pulled off the top timing cover and it's not coming from the cam seal. I checked the valve cover, that's tight. I'm gonna pull off the lower cover tomorrow and have a look in there. Yes, they're all tight.

I have a grand prix and it seems that I have a coolant leak in behind the water pump, how can that be and what part is behind the water pump.

The front cover bolts to the block with a gasket. It can leak coolant between the block and cover. That is a possible leak if the water pump is okay. Or the other leak is the coolant elbow above the water pump leaking down. Thanks for the reply, does the water pump bolt directly onto the block or is there a part between the pump and the block. I always thought the pump bolts directly to the block. Originally Posted by raythecaddie.

I read somewhere that you could remove the water pump and the timing chain cover all in one piece by removing only the 4 larger water pump bolts that go right through to the cover You still have to take the balancer pulley off with a special puller, then remove the front timing cover.
