Product Description

The Wehrli WCF100696-RED Upper Coolant Pipe is a premium replacement for the OEM upper radiator hose on 2011-2016 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks equipped with the 6.6L LML Duramax diesel engine. Finished in striking WCFab Red powder coat, this aluminum coolant pipe not only enhances engine bay aesthetics but also offers superior strength and reliability compared to the stock rubber hose. The precision bends ensure correct routing and clearance in the LML engine bay, delivering a direct fit without modifications.

Included high-quality silicone boots and heavy-duty T-bolt clamps make installation straightforward and provide a secure, leak-resistant seal at each connection point. While engineered for use with the OEM GM radiator, some aftermarket radiators may require adjustment for perfect alignment. This upgrade is ideal for owners seeking both functional durability and a customized look under the hood.
