It is known that the factory coolant plate is prone to leaks. The OEM plate uses a metal gasket that can corrode over time, causing leaks. The UnderDog Diesel Coolant Block-Off Plate for the GM 6.6L Duramax is the solution to this problem.

Machined from billet aluminum with an integrated O-ring seal, this plate is designed to permanently eliminate those leaks and keep your cooling system sealed for the long haul.

Features:

  • Integrated O-ring seal
  • Black anodized finish
  • Billet aluminum construction
  • Includes Grade 10.9 hardware

Note: You will lose approximately 4 gallons of coolant during installation. The downpipe must be moved out of the way to access the plate.
