The Wehrli Custom Fab top-outlet billet thermostat housing and upper coolant pipe kit for 2006–2010 Duramax LBZ/LMM replaces the OEM upper radiator hose and coolant return pipe, routing coolant upward and forward to free up space around the driver-side fuel system and accommodate larger turbos. Offered in a red powder-coat finish and available for single or twin CP3 configurations, the kit includes the coolant pipe, silicone boots and t-bolt clamps and is CNC-machined from billet aluminum.
