Wehrli 11-16 Chevrolet 6.6L LML Duramax Upper Coolant Pipe - Brizzle Blue

If you're working on the cooling system for your 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD, or the GMC Sierra equivalent with the 6.6L LML Duramax engine, this upper coolant pipe from Wehrli Custom Fabrication is a solid option. It swaps out the factory rubber hose for a well-built aluminum pipe, which can help prevent leaks and improve the look of your engine bay.

This pipe is finished in a Brizzle Blue powder coat, offering a clean, custom appearance. It comes with silicone boots and T-bolt clamps, ensuring a secure fit and good sealing. The aluminum construction is a step up from the stock rubber, offering more rigidity and resistance to heat cycles. It's designed to work with the OEM GM radiator, so you can expect a straightforward installation if you're keeping your original radiator.

When installing, make sure to refer to the manufacturer's instructions for proper boot and clamp tightening. This pipe is a direct replacement for the upper coolant hose, making it a practical upgrade for your Duramax truck.
