Construction & Design

The Wehrli Upper Coolant Pipe is expertly crafted from high-grade aluminum, chosen for its excellent thermal conductivity and resistance to corrosion. This material upgrade over the OEM rubber hose and plastic connector ensures a more durable and leak-resistant cooling pathway. The pipe’s Y-connector is precision-machined to match the exact specifications of the factory dual radiator system, guaranteeing seamless integration without the need for adapters or modifications.

The powder-coated finish not only enhances the visual appeal but also provides an additional layer of protection against environmental elements such as road salts, moisture, and heat. This robust construction makes the pipe well-suited for the demanding conditions faced by heavy-duty diesel trucks.

Installation & Fitment

Installation of the Wehrli Upper Coolant Pipe is straightforward and designed to be a direct replacement for the factory upper coolant hose assembly on 2013–2015 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins engine and dual radiator cooling system. No special tools or modifications are required when used with OEM Ram dual radiators. However, fitment with aftermarket radiators may vary if their inlet locations differ from the factory design, so compatibility should be verified prior to installation.

Replacing the original rubber hose and plastic connector with this aluminum pipe reduces the risk of coolant leaks and improves the overall reliability of the cooling system, especially under heavy load or extreme temperature conditions.
