Cometic GM 2001+ 6.6L Duramax .020in Rubber Coated Stainless Oil Cooler Outlet Gasket

This is the Cometic oil cooler outlet gasket, part number C15263, designed for GM 6.6L Duramax engines from 2001 through 2016. It's a specific gasket meant to seal the connection between the oil cooler and its outlet line, helping to prevent oil leaks and maintain proper oil pressure. If you're working on the oil cooler system of your Duramax truck, this gasket is a crucial component to ensure a leak-free repair.

This gasket is constructed with a rubber-coated stainless steel core. The stainless steel provides a solid base that resists corrosion and maintains its shape under pressure, while the rubber coating helps to create a tight seal against the mating surfaces. It's also specified as being .020 inches undersize, which is a common practice for oil cooler gaskets to ensure a snug fit and a reliable seal in the outlet port. This means it's designed to fit precisely into the oil cooler housing.

This gasket fits a wide range of GM trucks, including popular models like the Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD. When replacing your oil cooler or lines, always use a new gasket to prevent leaks. Refer to your vehicle's service manual for the correct installation procedure.
