The GMC Sierra 2500 Upper Coolant Pipe by Wehrli Custom Fabrication (WCFab) is a robust upgrade for your 2001-2005 GMC Sierra or Chevrolet Silverado equipped with the 6.6L Duramax LB7/LLY engine. This stunning upgrade comes in a sleek red powder-coated finish, offering not only durability but a standout appearance for your engine bay.

Designed to replace the factory-installed rubber upper radiator hose, this aluminum coolant pipe ensures enhanced durability and longevity, especially under the demanding conditions your diesel truck might face. Unlike traditional rubber hoses, the rigid aluminum construction minimizes the risk of leaks and issues related to heat expansion, offering superior thermal management. The transition from rubber to this high-quality aluminum design allows for a harder-wearing and more reliable solution.
