Product Description
Upgrade the durability and appearance of your Duramax engine bay with the WEHRLI CUSTOM FAB WCF100647 OEM PLACEMENT COOLANT TANK KIT designed specifically for 2011-2016 LML Duramax trucks. The factory plastic coolant reservoir is known to discolor, crack, and fail over time due to heat cycling and pressure changes in the cooling system. Wehrli Custom Fabrication engineered this high-quality aluminum replacement tank to eliminate those weaknesses while maintaining the factory mounting location for a clean OEM-style installation.
Constructed from precision TIG-welded aluminum, the WCF100647 coolant reservoir provides superior strength and durability compared to the original plastic tank. The kit installs in the OEM location and retains proper coolant level visibility while significantly improving engine bay aesthetics. This is a popular upgrade for both stock trucks and high-performance Duramax builds where reliability and clean engine bay layout matter.
