Description

The Wehrli WCF100420-FTB Top Outlet Billet Thermostat Housing and Upper Coolant Pipe Kit for 2006-2010 LBZ/LMM 6.6L Duramax replaces the OEM upper radiator hose and coolant return pipe, improving access to driver-side fuel system components and adding room for larger aftermarket turbochargers. It features a CNC machined billet aluminum thermostat upper housing and includes a coolant pipe, silicone boots, and t-bolt clamps. The kit is not compatible with 2006-2007 GMC Sierra models due to a lower profile hood, and it requires kit WCF100424 for vehicles with a WCFab Dual CP3 kit or a Dual Alternator Truck.
