Engine Oil Cooler Gasket & Seal Kit 2011-21 Chevy Duramax 6.6 LML L5P

Engine Oil Cooler Gasket & Seal Kit.

Includes all O-rings, Seals and Gaskets to remove and rebuild the engine oil cooler.

We include the large rectangular gasket for the 90° water casting, however we find it works best to use Permatex The Right Stuff ™ in place of this gasket.
