Service & Installation Notes

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

1. Allow the engine and exhaust system to cool completely, and disconnect the battery or disable starting before beginning service.
2. Support heavy exhaust manifolds and elbows securely during disassembly to prevent strain on mating surfaces or fasteners.
3. Clean all gasket mating surfaces and drain plug ports thoroughly, checking for warping, pitting, or corrosion that could prevent a reliable seal.
4. Verify the port layout of the manifold gaskets (3852455), elbow/riser gaskets (3850496), and drain plugs with O-rings (806608A02) against the removed parts and castings before assembly, then tighten fasteners to the sequence and specifications in your engine service manual.
5. After reassembly, inspect all manifold, riser, and drain plug joints during initial operation; shut down immediately and inspect if any exhaust or fluid leaks occur.
