Installation Guide Highlights

1. Preparation: Clean all mating surfaces thoroughly. Inspect the cylinder head gasket for damage; replace if necessary.
2. Bolt Placement: Insert each bolt into its designated hole, aligning with the factory torque sequence (typically a cross‑pattern). Use a torque wrench set to the specified values (usually 70–80 Nm).
3. Nut Tightening: Apply the nuts in the same cross‑sequence. Tighten gradually, ensuring even pressure distribution.
4. Final Check: Verify that all bolts are at the correct torque and that the head gasket is seated properly. Recheck after a short test run to confirm stability.
