Chevrolet Silverado 3500HD Upper Coolant Pipe by Wehrli, Aluminum, Bengal Grey (2011–2016). This direct-replacement pipe upgrades the factory rubber upper hose on LML Duramax trucks with a rigid, powder-coated aluminum unit designed for the OEM GM radiator.

Built for reliable performance and consistent coolant routing, the aluminum tube resists swelling and collapse under heat and pressure. The kit includes high-temp silicone boots and T-bolt clamps for a secure connection. Its single-stage Bengal Grey powder coat adds corrosion protection and a clean underhood look. Note: intended for OEM GM radiators; some aftermarket units may cause fitment issues.
