Problem: The original equipment oil cooler adapter relies on a metal gasket on the oil cooler that over time is prone to leaking as the cooler flexes. Fix: The Fleece Performance o il cooler adapter utilizes an integral square cut seal ring on the oil cooler mating surface in place of the leak prone gasket to provide a superior seal. Slotted mounting holes on one end allow for easier installation.Application Notes: Fits MY 2001-2007 and 2011-2019 Duramax engines Warranty: 1 Year Limited Parts Warranty Show more
