GMC Sierra Thermostat Housing Kit - Wehrli - Dual CP3 - Candy Teal - 08-10. This top-outlet billet housing and upper coolant pipe kit refines coolant routing for 2008-2010 Sierra Duramax builds focused on performance and serviceability.

By rerouting the OEM crossover hose upward and forward from the thermostat, it opens access to driver-side fuel components and creates clearance for larger turbochargers. Built for WCFAB Dual CP3 systems and compatible with dual alternator setups, it retains compatibility with factory VGT turbos. CNC-machined billet upper housing with coolant pipe, silicone boots, and T-bolt clamps included. Not compatible with PPE dual fueler kits. Replaces GM part numbers 19330105, 15792824, 25833204, 97361881. Required when running race-cover or SXE turbos in the valley.
