GMC Sierra 2500HD Upper Coolant Pipe - Wehrli - Gun Metal - 11-16. Replace the factory rubber upper hose with a precision aluminum pipe built for the LML Duramax.

Made by Wehrli Custom Fabrication, this pipe is a direct fit when used with the OEM GM radiator (some aftermarket radiators may affect fitment). Aluminum construction and a single-stage Gun Metal powder coat resist heat and aging, while included silicone boots and T-bolt clamps secure every connection. A smooth internal path supports consistent coolant flow and reliable temperature control.
