SIERRA 18-2375 Oil Drain Plug

Compatibility

The SIERRA 18-2375 oil drain plug is a critical component ensuring the sealing integrity of the lubrication system in the lower gearcase. Due to the nature of aftermarket part production, compatibility must be verified by the manufacturer catalog number (18-2375) or the original OE number. We do not list specific engine models to avoid selection errors. If in doubt, please contact our support team.

Installation and Maintenance

Proper installation guarantees safety. Before removal, ensure the engine is cooled down and the gearcase oil has been completely drained. Use only the appropriate wrench to avoid damaging the socket. Replace the plug regularly during every oil change to prevent leaks and water ingress into the gearcase interior.
