Wehrli 01-05 Chevrolet 6.6L LB7/LLY Duramax Upper Coolant Pipe - Sparkle Bomber Orange

When you're working on the cooling system for your 2001-2005 Chevrolet Silverado or GMC Sierra with the 6.6L Duramax LB7 or LLY engine, replacing the upper coolant pipe is a smart move. This aluminum pipe from Wehrli Custom Fabrication is built to last, offering a more robust solution than the original rubber hose that can degrade over time.

This pipe is constructed from aluminum and includes silicone boots and stainless steel T-bolt clamps, ensuring a solid connection that resists leaks and won't crack under pressure. The custom powder coat finish in Sparkle Bomber Orange not only looks sharp but also adds a layer of protection against corrosion. It's designed to be a direct replacement for GM part numbers 15792832 and 15198345, making installation straightforward.
