Oil drain plugs are essential components of the engine oil system that facilitate the draining of old oil during an oil change. Located at the bottom of the oil pan, the oil drain plug is threaded into the pan & tightly sealed to prevent oil leaks. When it's time to change the engine oil, the drain plug is removed using a wrench, allowing the old oil to drain out of the pan & into a collection container. Some drain plugs have a built-in gasket or sealing washer to ensure a tight seal when reinstalled. It's important to inspect the drain plug & gasket for any signs of damage or wear during each oil change & replace them if necessary. Proper torque should be applied when tightening the drain plug to prevent overtightening or stripping the threads. A well-maintained & properly functioning oil drain plug is crucial for maintaining the cleanliness & integrity of the engine oil, promoting optimal engine performance, & preventing oil leaks.
