GMC Sierra 2500 Upper Coolant Pipe by Wehrli, Gloss Black, 2020–2025. This fabricated aluminum hard pipe replaces the stock rubber upper radiator hose for a clean, durable upgrade.

Engineered for the 6.6L L5P Duramax, it fits 2020–2025 GMC Sierra 2500 and 3500 trucks that retain the OEM GM radiator. The gloss black powder coat is tough and cleans up the engine bay, and the included silicone boots with stainless steel T-bolt clamps create a reliable seal. Installation uses basic hand tools with no cutting, and the pipe directly replaces GM part numbers 84813629 and 85122989. Aftermarket radiators may affect fitment.
