GMC Sierra Upper Coolant Pipe - Wehrli - Aluminum - Flat Black - 01-05. Replace the factory rubber upper radiator hose on your 2001–2005 Duramax LB7/LLY with a durable, powder-coated aluminum upgrade.

Built as a direct-fit for Chevrolet Silverado and GMC Sierra 2500/3500 with the 6.6L LB7/LLY, this kit swaps the stock hose for a rigid aluminum pipe, high-temp silicone boots, and stainless T-bolt clamps. The flat black finish resists corrosion and keeps things tidy. Replaces GM 15792832 and 15198345. Note: this 01–05 pipe does not include a WCFab badge. Made in the USA.
