Cometic head gasket: what to know
A failed head gasket can mix coolant and oil, push coolant out of the system or cause overheating, so it is a job worth doing once and doing right.
Fitment notes
- Engine: match the engine size and code to your vehicle; the same model often came with several engines.
- Specs, lead time and warranty come from Cometic and can change. The details above this guide are the latest we have.

Ask about fitmentWhat else to plan for
- 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.
- Valve cover and intake gaskets. They come off during the job, so it is the time to replace them.
