Wehrli 11-16 Chevrolet 6.6L LML Duramax Upper Coolant Pipe - Illusion Purple

This aluminum upper coolant pipe from Wehrli is built for the 2011-2016 Chevrolet Silverado 2500 HD and 3500 HD, and their GMC Sierra counterparts, all equipped with the 6.6L LML Duramax engine. It's designed to replace the factory rubber upper coolant hose, offering a more solid and reliable connection that's less prone to swelling or failure over time. The pipe itself is constructed from aluminum, which is a strong material for this application, and it's finished with a custom two-stage powder coating in Illusion Purple for a unique look under the hood.

Included with the pipe are silicone boots and T-bolt clamps, ensuring a secure and leak-free seal when installed. This setup is intended for use with the OEM GM radiator; be aware that some aftermarket radiators might present fitment challenges. Upgrading to this aluminum pipe is a practical step for owners looking for improved longevity and a cleaner appearance in their cooling system.
