The Chevrolet Express Thermostat Housing Kit by Wehrli is a high-quality replacement for the OEM upper radiator hose of 2001-2005 LB7/LLY Duramax vehicles.
Candy Teal coating adds a vibrant touch, offering both enhanced functionality and style.

This CNC machined billet aluminum kit is designed to optimize your vehicle's engine bay by rerouting the coolant flow from the thermostat upwards and forward. By doing so, it grants improved access to the driver side fuel system components and provides additional room for larger aftermarket turbochargers, like the race cover style or SXE turbochargers. Furthermore, it's compatible with both single and dual CP3 pump setups, easily integrating into your custom builds.
