GMC Sierra 2500HD Upper Coolant Pipe by Wehrli (2011–2016) — Aluminum, Bengal Grey. This precision-formed pipe replaces the factory rubber upper coolant hose on LML Duramax trucks for a clean, durable upgrade.

Constructed from aluminum and finished in Bengal Grey powder coat, it’s designed for use with the OEM GM radiator. The rigid tube resists swelling, heat, and abrasion to help maintain consistent coolant flow and dependable routing. Kit includes high-temp silicone boots and sturdy T-bolt clamps for a secure, serviceable install. Note: some aftermarket radiators may cause fitment issues.
