Chevrolet Silverado 3500 Upper Coolant Pipe - Wehrli - Aluminum for Duramax LB7/LLY - Semi-Gloss Black - '01-'05. This direct-fit aluminum pipe replaces the factory rubber upper radiator hose on 2001–2005 GM 2500/3500 trucks with the 6.6L Duramax LB7/LLY.

Made in the USA by Wehrli Custom Fabrication, it resists expansion and heat for consistent coolant flow and long-term reliability. The semi-gloss black powder coat protects against corrosion, and the kit includes silicone boots and stainless T-bolt clamps for a secure connection. Direct replacement for GM 15792832 and 15198345; note: no WCFab badge on this model-year pipe.
