Keep your PCM engine cooling system sealed and serviceable with the PCM Blue Drain Plug. This hand-tightened, threaded plug features an integrated wing (T) handle for quick removal during routine maintenance and winterization. A built-in rubber O-ring helps create a reliable, watertight seal to reduce the chance of leaks after draining or servicing. Application: PCM engine cooling/drain port (service part) Design: Coarse male threads with integrated wing handle for tool-free tightening Seal: Black rubber O-ring for improved leak resistance Material/Finish: Molded plastic, corrosion-resistant, blue Category: Cooling System / Engine Service Parts Installation notes: Thread in by hand until the O-ring seats, then snug—do not overtighten. Inspect the O-ring for wear or cracking during service and replace the plug if the seal is compromised. FAQ Is this a direct replacement for a PCM cooling system drain plug?Yes—this plug is intended as a PCM service replacement for compatible drain/port locations. Match thread size and application to your specific engine before ordering. Do I need sealant or Teflon tape?Typically no—the O-ring provides the seal. Use sealant only if specified by the engine manufacturer.
