Wehrli 01-05 Duramax LB7/LLY Upper Coolant Pipe - Candy Teal

This Wehrli Custom Fab upper coolant pipe is what you get when you want to replace the stock rubber radiator hose on your 2001-2005 Duramax LB7 or LLY engine. You'll receive the aluminum coolant pipe itself, along with the necessary silicone boots and stainless steel T-bolt clamps to get it installed. It's designed to replace GM part numbers 15792832 and 15198345.

The aluminum construction means this pipe won't degrade like the factory rubber hose can over time, especially under the heat and pressure of a diesel engine. It's finished in a durable candy teal powder coat, giving your engine bay a custom look that stands out. This is a solid option if you're rebuilding the cooling system or just want to upgrade a known failure point on these trucks.
