2001-2005 Duramax Top Outlet Billet Thermostat Housing and Upper Coolant Pipe Kit, WC Fab Grey (Kingsport Grey) (WCF100405-GRY)

Top-outlet billet thermostat housing with a matching upper coolant pipe for the 2001-2005 LB7 and LLY Duramax. It reroutes the upper radiator hose up and forward from the thermostat instead of across the driver side valve cover, which clears the way to the fuel system, makes room for a bigger turbo in the valley, and tidies the engine bay.

Works with the factory VGT turbo and is required for race cover or SX-E turbos mounted in the valley. Compatible with single and dual CP3 setups. Includes the CNC-machined billet upper housing, coolant pipe, silicone boots and T-bolt clamps, powder coated in your choice of colour. Replaces GM 15792832 and 15198345.
