Wehrli 11-16 Chevrolet 6.6L LML Duramax Upper Coolant Pipe - WCFab Grey

This is the Wehrli Upper Coolant Pipe, designed specifically for 2011-2016 Chevrolet Silverado 2500 HD and 3500 HD trucks with the 6.6L LML Duramax engine. It replaces the factory rubber upper coolant hose, offering a more robust and long-lasting solution for your truck's cooling system. The pipe is constructed from aluminum and finished in a WCFab Grey powder coat for a clean look and added protection.

The factory rubber hose can degrade over time, especially under the demands of a Duramax engine. This aluminum pipe, paired with the included silicone boots and T-bolt clamps, provides a more solid connection that resists expansion and heat fatigue. The custom two-stage powder coating ensures the finish holds up well against engine bay conditions. It's designed to work with the OEM GM radiator, ensuring a straightforward installation for most applications.
