• Rough running or misfire conditions tied to head gasket failure

Installation Notes

Use graphite cylinder head bolts when installing this engine cylinder head gasket, as noted in the fitment data. Verify the cylinder bore diameter, thickness, and left-side application before installation. Follow the vehicle service manual for surface preparation, torque sequence, and torque-to-yield tightening procedures. Confirm the head and block surfaces are clean, flat, and free of debris before assembly.
