Wehrli 06-10 Chevrolet 6.6L LBZ/LMM Duramax Upper Coolant Pipe - Brizzle Blue

If you're working on the cooling system for your 2006-2010 Chevrolet or GMC truck with a 6.6L Duramax LBZ or LMM engine, this aluminum upper coolant pipe from Wehrli is a solid upgrade over the factory rubber hose. Over time, those rubber hoses can swell, crack, or even burst, leading to coolant leaks and potential engine overheating. This pipe offers a more robust solution that's built to last.

This pipe is constructed from aluminum, which won't degrade like rubber can, and it's finished with a durable Brizzle Blue powder coat that looks great and resists corrosion. It comes with silicone boots to ensure a good seal and stainless steel T-bolt clamps for a secure connection. Wehrli makes these in the USA, and they're designed to fit right in place of the original equipment part, making the installation straightforward. It's a popular choice for Duramax owners looking to improve the reliability of their cooling system.

This pipe replaces GM part numbers 19330105, 15792824, and 25833204. It's a well-built component that can help prevent future coolant issues.
