GMC Sierra 3500 Upper Coolant Pipe - Wehrli - Gun Metal - 01–05. This aluminum pipe is a direct replacement for the factory rubber upper radiator hose on LB7/LLY Duramax trucks.

Built by Wehrli Custom Fabrication (WCFab), it fits 2001–2005 Silverado/Sierra 2500/3500 with the 6.6L Duramax LB7/LLY and replaces GM part numbers 15792832 and 15198345. The Gun Metal powder coat resists corrosion, and the kit’s high-temp silicone boots plus stainless T-bolt clamps provide a secure, serviceable connection. Note: this 01–05 version does not include a WCFab badge.
