What it does
Hoses, the thermostat and the cap age together, so they are often replaced as a group. 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 and refill with the coolant type your engine needs, then bleed the air out.
- Coolant: Use the correct type.
- Thermostat: Cheap while the system is drained.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
