Is the water pump pulley part of the water pump?

Is the water pump pulley part of the water pump?

A water pump pulley is a pulley attached to the water pump system in a car to connect it with the timing belt. The timing belt wraps around a number of pulleys in the engine compartment to control the function of accessory systems in the vehicle.

Can you replace the pulley on a water pump?

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.

Can a bad pulley cause coolant leak?

It is more likely that something above or behind the idler pulley is leaking coolant and migrating to other areas, like the idler pulley. The cooling system should be pressure tested by a certified technician, like one from YourMechanic, to find the source of the coolant leak.

What type of sound does a bad water pump make?

One way to check for worn out or failed water pump bearing; is to check for water pump shaft movement. So, with a faulty bearing, you can often hear a squealing, howling; or sometimes a grinding noise coming from the front of the engine.
