Wehrli 11-16 Chevrolet 6.6L LML Duramax Upper Coolant Pipe - Semi-Gloss Black

If you're working on the cooling system for your 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD, or the GMC Sierra equivalent, this upper coolant pipe from Wehrli Custom Fabrication is a solid option. It replaces the factory rubber upper coolant hose with a more durable aluminum pipe, helping to prevent leaks and potential blowouts that can happen with aged rubber components. This pipe is specifically designed for the 6.6L LML Duramax engine and is intended for use with the OEM GM radiator.

The aluminum construction is finished in a semi-gloss black powder coat, which not only looks good but also adds a layer of protection against corrosion. It comes with silicone boots and T-bolt clamps, making installation straightforward. Using a metal pipe instead of rubber can offer improved longevity, especially in high-heat environments common for these trucks.
