Coolant Plate (Chevy/GM Duramax 2001-2025 6.6L)

Put the Smashed Performance Coolant Plate in your GM 6.6L Duramax to permanently eliminate coolant leaks from the rear housing on your Duramax engine. The factory cover uses a gasket and over time the plate can warp, and the gaskets can corrode causing coolant leaks. The Plate is made from CNC-machined billet aluminum and features a built-in o-ring seal for a leak-free installation. Each coolant plate comes with a black anodized finish and is ready to install re-using your factory hardware.

FEATURES:

• Built-In O-Ring Seal
• Black Anodized Finish
• Billet Aluminum Construction
• Eliminate Rear Housing Coolant Leaks
