Construction & Design

The upper coolant pipe is crafted from lightweight yet robust aluminum, chosen for its excellent thermal conductivity and resistance to cracking under heat and pressure. The pipe features a precision-machined Y-connector that replicates the OEM design but eliminates the weak plastic junction prone to failure. Each unit is finished with a durable powder coat that protects against corrosion and wear while offering a clean, professional appearance under the hood.

Wehrli’s engineering ensures that the pipe aligns perfectly with the OEM dual radiator inlet locations, providing a secure and leak-free connection. The design maintains factory coolant flow dynamics, ensuring optimal engine cooling performance without compromise.

Installation & Fitment

Installation is straightforward and designed to be a direct replacement for the factory upper coolant hose on 2013–2015 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins engine and dual radiator configuration. No modifications are necessary when used with OEM dual radiators. Simply remove the old rubber hose and plastic connector assembly and install the Wehrli aluminum pipe using the existing mounting points and clamps.

Note that aftermarket radiators with different inlet locations may cause fitment issues. This product is engineered specifically for OEM dual radiator setups to ensure a precise fit and reliable operation.
