Chevrolet Duramax Thermostat Housing Kit - Wehrli - Billet - Sparkle Bomber Orange - `01-`05. This CNC-machined top-outlet housing and upper coolant pipe kit refines the 2001-2005 LB7/LLY cooling layout with a Sparkle Bomber Orange two-stage powder coat.

It replaces the OEM upper radiator hose that crosses the driver-side valve cover and the coolant return pipe, re-routing flow upward and forward from the thermostat. This provides cleaner access to driver-side fuel system components and extra room for larger aftermarket turbochargers. Compatible with factory VGT turbos and Single or Dual CP3 pump setups, and required when running race-cover or SXE turbos in the valley. Includes coolant pipe, silicone boots, and T-bolt clamps, and cross-references GM 15792832 and 15198345. Made in the USA.
