Wehrli 06-10 Chevrolet 6.6L LBZ/LMM Duramax Upper Coolant Pipe - Gloss White

Wehrli Custom Fabrication is known for making well-built parts for Duramax trucks. This upper coolant pipe is a prime example, designed to replace the stock rubber hose on your 2006-2010 LBZ or LMM 6.6L Duramax-equipped Chevrolet Silverado or GMC Sierra. It’s a solid option for anyone looking to improve the cooling system's reliability and appearance.

This pipe is constructed from aluminum, which is lighter than the original rubber and less prone to cracking or collapsing under pressure. It comes with durable silicone boots and stainless steel T-bolt clamps for a secure, leak-free connection. The gloss white powder coat finish not only looks sharp but also adds a layer of protection against corrosion and staining, making it a popular choice for custom builds. It directly replaces GM part numbers 19330105, 15792824, and 25833204.

This coolant pipe fits a range of heavy-duty trucks, including the 2006-2010 Chevrolet Silverado 2500 HD and 3500 HD, as well as the 2006-2010 GMC Sierra 2500 HD and 3500 HD. It's a straightforward replacement for the factory hose, offering improved durability and a cleaner look under the hood.
