Wehrli 06-10 Chevrolet 6.6L LBZ/LMM Duramax Upper Coolant Pipe - Flat Black

This is the Wehrli Custom Fab upper coolant pipe, designed to replace the stock rubber hose on 2006-2010 Chevrolet Silverado and GMC Sierra trucks equipped with the 6.6L Duramax LBZ or LMM engine. Over time, the factory rubber hose can degrade and lead to coolant leaks, which can cause your engine to overheat. This aluminum pipe offers a more robust and long-lasting solution for your truck's cooling system.

Crafted from aluminum, this pipe is built to withstand the heat and pressure of the Duramax engine, offering a solid upgrade over the original rubber component. It comes finished in a durable flat black powder coat, which not only looks good but also helps protect the aluminum from corrosion. The kit includes silicone boots and stainless steel T-bolt clamps, ensuring a secure and leak-free installation when properly fitted. This part is made in the USA, reflecting a commitment to solid construction.

This upper coolant pipe is a direct replacement for the factory part and is designed to fit a range of Duramax-equipped trucks from 2006 to 2010, including popular models like the Silverado 2500 HD and Sierra 3500 HD. It's a practical choice for anyone looking to improve the reliability of their truck's cooling system.
