GMC Sierra Thermostat Housing Kit - Wehrli - Dual CP3 - Kiwi Green (2008-2010). A billet top-outlet thermostat housing and upper coolant pipe kit that reroutes coolant for a cleaner, more serviceable engine bay.

Designed for 2008-2010 GMC Sierra Duramax running WCFAB Dual CP3s, it replaces the upper radiator hose and coolant return pipe, routing flow upward and forward from the thermostat. This improves access to driver-side fuel components and adds clearance for larger turbochargers. Includes a CNC-machined billet upper housing, formed coolant pipe, silicone boots, and T-bolt clamps. Compatible with factory VGT turbos and dual alternators; required when using race cover or SXE turbos in the valley. Not for PPE dual fueler kits or 2006-2007 Sierra.

Features

• Upward/forward coolant routing from thermostat
