Service & Installation Notes
General service guidance only. Use the service manual for your exact engine and exhaust configuration.
- Shut down the engine, allow the cylinder block and exhaust manifold to cool completely, and disable the starting circuit before servicing any drain point.
- Remove the existing drain plug and compare its connection and sealing arrangement directly with the replacement plug.
- Clean the mating drain boss or fitting threads carefully to protect the sealing surfaces from debris or thread damage.
- Install the drain plug according to the procedures in your engine service manual. If leakage or abnormal seating occurs during inspection, stop operation and inspect the drain fitting and sealing surfaces.
