Engine Oil Drain Plug Seal, Duramax | 2007.5 - 2022

The GM 12616850 oil drain plug seal is the O-ring that seals the engine oil pan drain plug. It fits 2007.5-2022 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks with the 6.6L LMM, LML or L5P Duramax, Chevrolet Express and GMC Savana vans with the 6.6L or 2.8L Duramax, and 2016-2022 Chevrolet Colorado and GMC Canyon with the 2.8L Duramax. The seal flattens and hardens each time the plug is torqued, so a reused seal is the most common cause of a slow drip from the oil pan. Install a new seal at every oil change.

Key Features

• GM part number 12616850

• Factory size for a leak-free seal
• Fits 6.6L LMM, LML, LGH, L5P and 2.8L LWN Duramax engines

Benefits

A new seal at every oil change keeps the drain plug dry and avoids over-tightening the plug to chase a leak. If the plug itself is worn or its threads are damaged, see the Engine Oil Drain Plug. Pick up an ACDelco Oil Filter for 6.6L trucks, or the Duramax 2.8L Oil Change Kit for the Colorado, Canyon, Express and Savana.
