Chevrolet Silverado 3500HD Thermostat Housing Kit - Wehrli - Dual CP3 - Candy Red - 06-10. A billet solution for 2006–2010 LBZ/LMM Duramax that cleans up coolant routing and opens service room.

Replacing the factory upper radiator hose and coolant return pipe, this kit re-routes flow upward and forward from the thermostat for easier access to driver-side fuel components and added clearance for larger valley-mounted race-cover or SXE turbos. Designed for WCFab Dual CP3 systems and compatible with dual alternators, it also works with factory VGT turbos. The CNC-machined billet aluminum upper housing arrives in Candy Red, and the kit includes the formed coolant pipe, silicone boots, and T-bolt clamps. Not compatible with PPE dual-fueler kits or 2006–2007 GMC Sierra. Replaces GM PNs 19330105, 15792824, 25833204, 97361881.
