Located at the lower part of the engine, on the aluminum oil pan, and may require removal of the engine undercover. Introduction to the drain plug: The oil pan drain plug is a screw located at the bottom of the engine oil pan. When performing an oil change during engine maintenance, this screw is loosened to drain the old engine oil, and then tightened before adding new oil through the engine's fill port. Drain plug replacement interval: The drain plug itself generally does not need replacement, but the washer should ideally be replaced each time. Unless the vehicle has a plastic oil pan, in which case the drain plug is one-time use and must be replaced every time. Most vehicle drain plugs are made of steel, which is durable and unlikely to be damaged under normal use. Replacement is only necessary if the threads are accidentally misaligned and excessive force is applied. Generally, replacement is not required.
