The Chevrolet Silverado Thermostat Housing Kit - Wehrli - Top Outlet Billet - Sparkle Bomber Orange - `06-`10 reroutes the upper coolant path on 2006–2010 LBZ/LMM Duramax trucks. It replaces the factory hose and return pipe for a cleaner, smarter layout.

Routing flow upward and forward from the thermostat improves access to driver-side fuel components and opens space for larger aftermarket turbochargers. Finished in Sparkle Bomber Orange, the CNC billet upper housing works with factory VGT turbos and is required for race-cover or SXE turbos mounted in the valley. Choose single CP3 (WCF100420) or twin/dual-alternator (WCF100424). Replaces GM 19330105, 15792824, 25833204, 97361881. Not compatible with 2006–2007 GMC Sierra.
