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.
