How can I tell if my water pump pulley is out of alignment?
How can I tell if my water pump pulley is out of alignment?
Grab a flashlight and visually check the water pump pulley for any cracks and to see if it is out of alignment. Step 2: Start the engine and test the pulley. With the engine started, check whether the pulley is working correctly. Watch for any wobbling or note if it makes any noises as if the bolts are loose.
How do you remove a pulley from a water pump?
If the vehicle has a v-belt, you can simply loosen the tensioner to relax the belt. Once the belt is loose enough, remove it from the pulleys. Note: To remove the pulley bolts, you may have to go under the vehicle or go through the fender near the wheel to access the bolts. Step 4: Remove the pulley from the water pump.
What causes a water pump pulley to crack?
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.
Can a water pump on a car fail?
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.
Can a water pump rotate without a pulley?
Water pump pulleys are designed to be driven by a drive belt or serpentine belt. Without a pulley, a water pump will not rotate unless it is driven by the timing belt, timing chain, or an electric motor.
What does it mean when your water pump belt is missing?
There are many different types of water pump or serpentine belts that power the water pump and additional systems. Some of them are grooved while others are smooth. If you or another mechanic notices that grooves from a belt are missing, it’s also a good indication that the belt is ready to break and needs to be replaced.
What causes a water pump pulley to wobble?
Cracks can also form on the pulley if the bolts come loose or the pulley has too much stress applied to it. Additionally, the pulley can bend if the belt is at an angle because of an accessory that is not aligned properly. This will cause the pulley to have a wobble effect.

What causes a serpentine belt to be out of alignment?
Angular misalignment—the pulley is at an angle to the other pulleys—results from worn bearings in an accessory. Belt tension on the pulley pulls the shaft off center, which puts that pulley out of alignment with the other pulleys. Pulley alignment can be checked with a straightedge. Place the straightedge across two pulley faces.
