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.
