Wehrli 06-10 Chevrolet 6.6L LBZ/LMM Duramax Upper Coolant Pipe - WCFab Grey

This aluminum upper coolant pipe from Wehrli Custom Fabrication is built to replace the stock rubber hose on 2006-2010 Chevrolet and GMC trucks equipped with the 6.6L LBZ or LMM Duramax engine. The factory rubber hose can degrade over time, leading to leaks or reduced coolant flow, especially under demanding conditions. This upgraded pipe offers a more robust solution for keeping your engine running cool.

Constructed from durable aluminum, this pipe is designed to handle the heat and pressure of the cooling system without the risk of swelling or cracking that can affect rubber components. It comes with silicone boots for a secure seal and stainless steel T-bolt clamps, ensuring a solid connection. The pipe is finished in a WCFab Grey powder coat, adding a clean, custom look under the hood while resisting corrosion and wear. This part is made in the USA and is a direct replacement for GM part numbers 19330105, 15792824, and 25833204.

This coolant pipe fits a range of heavy-duty trucks, including the Chevrolet Silverado 2500 HD and 3500 HD, as well as the GMC Sierra 2500 HD and 3500 HD models from 2006 through 2010. It's a well-built upgrade for Duramax owners looking for a more reliable cooling system component.
