2001-2022 Duramax Billet Coolant Block Off Plate (10089)

The Duramax Diesel trucks from 2001-2018 have a coolant block off plate on the rear. The original plate had a gasket on the surface for the mating surface. Sadly, over time, this plate is known to have coolant leakage issues due to warping or gasket problems.

The Solution: This Duramax Billet Coolant Block Off Plate! This upgraded, high-performing billet aluminum creation is built to perform better than your OEM plate. Made in the USA with a black anodized finish, this plate features a built-in O-ring for better sealing and a longer lifespan. And don't stress about installation - just use your factory hardware and you're good to go!
