Good To Know

Q: Do I need to replace the head gasket every time the cylinder head is removed? A: Yes, head gaskets are single-use components and should be replaced each time the cylinder head is removed to ensure a proper seal.

Q: Are new head bolts required with this gasket? A: Check your service manual, as some engines require new torque-to-yield fasteners, while others allow reuse if within spec.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
