What it does
Pumps wear at the bearing and seal. A leak from the weep hole or a growling noise usually means it is time. A healthy cooling system keeps the engine at its working temperature; most cooling parts are replaced because of leaks, corrosion or a failed bearing or seal.
Installation & tips
- Flush the old coolant and refill with the type your engine specifies, then bleed air out of the system.
- Thermostat: Cheap to replace while the system is drained.
- Coolant: Refill with the correct type.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
