Wehrli 01-05 Chevrolet 6.6L LB7/LLY Duramax Upper Coolant Pipe - Gloss Black

This aluminum upper coolant pipe from Wehrli Custom Fabrication is a solid upgrade for your 2001-2005 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the 6.6L Duramax LB7 or LLY diesel engine. It directly replaces the factory rubber upper radiator hose, which can degrade over time and lead to leaks. The pipe itself is constructed from aluminum, offering a more robust solution than the original rubber component.

The pipe comes finished in a durable gloss black powder coat, which not only looks sharp but also helps protect the aluminum from corrosion. It includes silicone boots for a secure, leak-free connection and stainless steel T-bolt clamps for strong, reliable tightening. This setup is designed to fit right, making the replacement process straightforward for those familiar with working on these trucks.
