What it does
Gaskets seal the joints between engine parts so oil, coolant and air stay where they belong. 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
- Clean both mating surfaces completely and follow the bolt torque and sequence for your engine.
- Sealant where called for: Some joints need a dab of sealant at corners or seams; others must go on dry.
- Bolts and grommets: Rubber grommets and old bolts are worth replacing if they are damaged.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
