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

This Wehrli Custom Fab upper coolant pipe is what you get when you want to replace the stock rubber hose on your 2001-2005 Chevrolet Silverado or GMC Sierra 2500/3500 with the 6.6L Duramax LB7 or LLY engine. You'll receive the aluminum coolant pipe itself, which is finished in a tough Chevy Orange powder coat, along with stainless steel T-bolt clamps and silicone boots to make the connection secure.

This aluminum pipe is a solid upgrade over the factory rubber hose, which can sometimes degrade or become brittle over time. The powder coat finish not only looks sharp but also adds a layer of protection against corrosion. The stainless steel T-bolt clamps are known for their strength and ability to maintain consistent pressure, helping to ensure a leak-free seal with the silicone boots.

This part is designed to be a direct replacement for GM part numbers 15792832 and 15198345, making installation straightforward. It's a well-built piece that addresses a common point of wear on these Duramax trucks.
