Chevrolet Silverado 3500 Upper Coolant Pipe - Wehrli - Bengal Silver - ’20–’25. A direct-fit aluminum upgrade that replaces the factory rubber upper radiator hose on 2020–2025 6.6L L5P Duramax models.

Built by Wehrli from fabricated aluminum and finished in Bengal Silver powder coat, this hard pipe cleans up the engine bay and resists heat, swelling, and aging better than rubber. Designed for use with the OEM GM radiator, it installs on stock trucks with basic hand tools and requires no cutting. Includes high-quality silicone boots and stainless T-bolt clamps for a secure connection. Replaces GM part numbers 84813629 and 85122989.
