What it does
Head gasket jobs take the top of the engine apart, which is why most people replace the related gaskets and bolts at the same time. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.
Installation & tips
- Most head gaskets call for new head bolts and a flat, clean deck surface. Check the head and block before you reassemble.
- Head bolts: Many engines use torque-to-yield head bolts that should not be reused.
- Coolant: Refill with the coolant type your engine calls for.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
