09168-10022 Suzuki Gasket, Drain Plug

Sulfuric Acid Burn Hazard may cause serious personal injury or death.The exhaust gas cooler may contain a small amount of sulfuric acid. The use of fuel with sulfur levels greater than 15 ppm may increase the amount of sulfuric acid formed. The sulfuric acid may spill from the cooler during service of the engine. The sulfuric acid will burn the eyes, skin and clothing on contact. Always wear the appropriate personal protective equipment (PPE) that is noted on a material safety data sheet (MSDS) for sulfuric acid. Always follow the directions for first aid that are noted on a material safety data sheet (MSDS) for sulfuric acid.
Note: Plug or cap all open ports with new plugs or caps.
Drain the coolant from the cooling system into a suitable container for storage or disposal. Refer to Operation and Maintenance Manual, "Coolant - Change" for the correct procedure.

If necessary, remove differential temperature and absolute pressure sensor (25) from exhaust cooler assembly (19). Refer to Disassembly and Assembly, Pressure Sensor (NRS Absolute) - Remove and Install for the correct procedure.Installation Procedure
Check all components for wear and damage. If necessary, replace any components that are worn or damaged.Note: Remove plugs and caps that were previously installed prior to assembly.
Ensure that the NRS exhaust cooler is free from restriction and external damage. Ensure that the NRS exhaust cooler and tube assemblies are free from wear and damage. Refer to Systems Operation Testing and Adjusting, "Exhaust Cooler (NRS) - Test" for the correct inspection procedure.Note: The NRS exhaust cooler, should not be internally cleaned.
