Fleece Oil Cooler Adapter Kit for 2001-2007, 2011-2019 Chevy/GMC 6.6L Duramax

FPEFPE-DMAX-OCADPT

Oil seeping from the cooler area on a Duramax is a common leak, and it has a simple fix.

The OE oil cooler adapter relies on a metal gasket at the oil cooler, and as the cooler flexes over time that gasket is prone to leaking. Fleece's adapter uses an integral square cut seal ring on the oil cooler mating surface instead, for a better seal that stays sealed.

Why it seals better

  • Integral square cut seal ring replaces the leak prone gasket
  • Superior seal at the oil cooler mating surface
  • Slotted mounting holes on one end make installation easier

  • Engine: 6.6L Duramax
