Replace the drain plug in your 1982-2000 Chevy/GMC 6.2L/6.5L Diesel with new Oil Drain Plugs & Valves. A standard drain plug can become damaged, rounded, cracked, or stripped which can result in damage to the oil pan, or oil leaks. In most applications replacing your drain plug is an inexpensive way to avoid future hassles during preventative maintenance. Upgraded oil drain plugs are available for most applications and make it easy for you to quickly and cleanly drain your engine oil with just the turn of a lever. Fumoto, Mishimoto, Dorman, and EZ Oil Drain are just some the top brands you'll find.
