About this head gasket

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.

Ask about fitment

Parts that usually go with it

  • 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.
