If the threads are stripped on the original equipment oil pan drain plug or pan on certain vehicles, or the plug is missing, this universal oil drain plug can be a cost-effective alternative to trying to tap new threads or replacing the entire oil pan. Designed to fit pans with factory drain plugs from .500 inch to .750 inch or M12 to M18, the plug installs easily to provide a reliable seal against the pan to help prevent leaks. Please note that this plug protrudes 1.625 inch into the oil pan. Some vehicles may lack the clearance required for safe use of this part, including some Honda and Volkswagen models. Confirm the drain plug has adequate clearance from the oil pump, pickup, crankshaft and any other components before running the engine.
