Service & Installation Notes

General service guidance only. Use the service manual for your exact engine and exhaust configuration.

1. Ensure the engine is completely cool and secured against accidental starting before loosening any exhaust elbow or riser fasteners.
2. Support the weight of the exhaust elbow or riser during removal and reinstallation, and protect both mating surfaces at the manifold-to-elbow/riser joint from nicks or debris.
3. Compare the new gaskets directly against the removed gaskets and mating passages to verify port alignment and orientation before tightening fasteners to the engine manufacturer's specifications.
4. Inspect the joint during initial operation; if any exhaust or water leak is observed, shut down the engine immediately and inspect the sealing surfaces.
