Chevrolet Silverado Thermostat Housing Kit - Wehrli - Dual CP3 - Cat Yellow - 06-10. A billet top-outlet thermostat housing and upper coolant pipe kit for 2006-2010 Duramax LBZ/LMM Silverado Dual CP3 builds.

This kit replaces the OEM upper radiator hose that crosses the driver side valve cover as well as the coolant return pipe, rerouting flow upward and forward from the thermostat. The revised layout improves access to driver-side fuel components and adds room for larger aftermarket turbochargers. Designed for WCFab Dual CP3 systems and also compatible with dual alternator setups; compatible with factory VGT turbos. Required when using race cover or SXE turbos mounted in the valley. Not compatible with PPE dual fueler kits or 2006-2007 GMC Sierra. Replaces GM part numbers 19330105, 15792824, 25833204, 97361881.
