Description

Wehrli Model WCF100405

The Top Outlet Billet Thermostat Housing and Upper Coolant Pipe Kit for 2001-2005 LB7/LLY Duramax replaces the OEM upper radiator hose that normally crosses over the driver side valve cover as well as the coolant return pipe. By changing the coolant routing to an upwards and forward layout from the thermostat, this kit improves access to driver side fuel system components, adds room for larger aftermarket turbochargers, and updates the engine bay appearance.

  • Compatible with factory VGT style turbochargers
  • Required for race cover style or SXE turbochargers being mounted in the valley
  • CNC Machined Billet Aluminum Thermostat Upper Housing
  • Includes coolant pipe, silicone boots, and t-bolt clamps
  • WILL work with WCFab Dual CP3 applications
  • Replaces the following GM Part numbers: 15792832, 15198345
