Wehrli Upper Coolant Pipe

2013–2015 Ram 2500 / 3500 6.7L Diesel

Part #: WCF100867-BS

Overview

The Wehrli Upper Coolant Pipe is a direct replacement for the OEM rubber upper coolant hose with a plastic connector on 2013–2015 Ram 2500 and 3500 Heavy Duty trucks equipped with the 6.7L Cummins diesel engine and dual radiator setup. Designed specifically for vehicles with dual radiators, this aluminum coolant pipe eliminates the common failure points found in the factory hose, providing a durable and leak-resistant solution. It is an ideal upgrade for owners seeking improved reliability and longevity in their cooling system.

This upper coolant pipe features a Y-connector that perfectly matches the OEM dual radiator configuration, ensuring proper coolant flow and fitment. The product is powder coated in Bengal Silver for corrosion resistance and a clean, professional appearance under the hood.

Key Features

Engineered to enhance cooling system durability and reliability, the Wehrli Upper Coolant Pipe offers the following benefits:

• Constructed from high-quality aluminum for superior strength and heat resistance
• Replaces the OEM rubber hose and plastic connector prone to cracking and coolant leaks
• Designed specifically for Ram 2500 and 3500 trucks with dual radiator setups (2013–2015)
• Powder coated in Bengal Silver for corrosion protection and a sleek finish
• Direct bolt-on replacement with no modifications required when used with OEM dual radiators
• Compatible with factory MOPAR part numbers 52014722AD, 52014722AB, and 52014722AC
• Y-connector design ensures proper coolant distribution between dual radiators
• Improves cooling system reliability by eliminating failure-prone plastic components

Construction & Design

The Wehrli Upper Coolant Pipe is precision-machined from durable aluminum, chosen for its excellent thermal conductivity and resistance to corrosion. Unlike the OEM rubber hose with a plastic connector, this pipe offers a robust one-piece design that withstands the high temperatures and pressures typical of diesel cooling systems. The powder-coated finish in Bengal Silver not only enhances corrosion resistance but also adds a professional aesthetic that complements the engine bay.

Its Y-connector is engineered to match the exact inlet locations of the OEM dual radiator system, ensuring a perfect fit and optimal coolant flow. This design reduces the risk of leaks and failures commonly associated with the factory hose and connector assembly.

Installation & Fitment

Installation is straightforward and designed for a direct swap with the factory upper coolant hose on 2013–2015 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine and dual radiators. No special tools or modifications are necessary when used with OEM dual radiator setups. It is important to note that aftermarket radiators with different inlet locations may cause fitment issues.

Replacing the original rubber hose and plastic connector with this aluminum pipe enhances the durability of your cooling system and reduces the likelihood of coolant leaks, helping maintain optimal engine temperatures and performance.
