What happens if the pulley on a water pump breaks?
If a belt breaks off or a pulley breaks, then only the circuit with the belt is no longer operational. If the alternator belt breaks off but the water pump belt does not break, then the engine can still run as long as the battery still has a charge. A multi-groove pulley is a multi-depth pulley that can only drive a serpentine belt.
How do you install a new water pump pulley?
Step 1: Install the new pulley onto the water pump shaft. Screw in the mounting bolts and hand tighten them. Then torque the bolts to the recommended specifications that should have come with the pulley. If you do not have any specs, you can torque the bolts to 20 foot pounds and then an additional 1/8 turn.
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.
Can a V-groove pulley have more than one groove?

What’s the best way to replace a water pump pulley?
If you are reinstalling a serpentine belt, use the breaker bar to relax the tensioner and slide the belt onto the last pulley. If you are reinstalling a v-belt, slide the tensioner over and tighten it. Make adjustments to the v-belt by loosening and tightening the tensioner until the belt is loose to its width or about a 1/4 inch.
