2006-2010 LBZ/LMM Duramax Top Outlet Billet Thermostat Housing and Upper Coolant Pipe Kit for DUAL CP3Candy Teal

This Wehrli Custom Fabrication (WCFab) kit replaces the OEM upper radiator hose and coolant return pipe in 2006-2010 LBZ/LMM Duramax engines. It reroutes coolant from the top of the thermostat housing directly to the radiator, improving access to driver-side fuel system components and providing room for larger aftermarket turbochargers. Crafted from CNC machined billet aluminum with a Candy Teal powder coat finish, it includes a coolant pipe, silicone boots, and t-bolt clamps. It is designed for use with WCFAB DUAL CP3s and compatible with dual alternator setups. Not compatible with PPE dual fueler kits or 2006-2007 GMC Sierra.
