What it does
The head gasket seals the cylinder head to the block, keeping combustion pressure in the cylinders and coolant and oil in their own passages. 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.
- 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.
