Chevrolet Silverado 2500HD Thermostat Housing Kit – Wehrli – Billet – Deore Gold – 06–10. A top‑outlet thermostat housing and upper coolant pipe engineered for LBZ/LMM Duramax trucks.

Replaces the OEM upper radiator hose that crosses the driver‑side valve cover and the coolant return pipe, re‑routing coolant upward and forward from the thermostat. This cleans up the path, improves access to driver‑side fuel components, and makes room for larger aftermarket turbos. Compatible with factory VGT turbos and required for race‑cover or SXE turbos in the valley. Fits single or twin CP3; dual CP3 or dual‑alternator trucks use WCF100424. Not compatible with 2006–2007 GMC Sierra.

Features

• CNC‑machined billet thermostat upper housing
• Coolant pipe, silicone boots, and T‑bolt clamps
• Upward/forward routing for better service access
• Deore Gold powder coat finish
