Wehrli Upper Coolant Pipe

2013–2018 Ram 2500 / 3500 6.7L Diesel

Part #: WCF100517-SBO

Overview

The Wehrli Upper Coolant Pipe is a premium replacement for the OEM rubber upper coolant hose found on 2013 to 2018 Ram 2500 and 3500 heavy-duty trucks equipped with the 6.7L Cummins diesel engine. Designed to improve durability and reliability, this aluminum coolant pipe replaces the factory rubber hose that connects to the radiator inlet. It is an ideal upgrade for owners seeking a more robust cooling system component that withstands high temperatures and harsh operating conditions.

Finished in a vibrant Sparkle Bomber Orange powder coat, this upper coolant pipe not only enhances engine bay aesthetics but also provides excellent corrosion resistance. It is engineered for use with the OEM RAM radiator to ensure proper fitment and reliable performance without modification.

Key Features

This upper coolant pipe offers several advantages over the stock rubber hose, combining quality materials and precise engineering:

• Constructed from lightweight, durable aluminum for superior heat dissipation and strength
• Powder coated in Sparkle Bomber Orange for corrosion resistance and a striking appearance
• Direct OEM replacement for the upper radiator inlet hose on 2013–2018 Ram 2500/3500 6.7L Cummins trucks
• Compatible with factory RAM radiators to maintain proper coolant flow and fitment
• Eliminates the common failure points of rubber hoses such as cracking, swelling, and leaks
• Replaces multiple Mopar part numbers including 68166469AC, 68166469AA, 68166469AB, and others for easy cross-reference
• Enhances engine bay aesthetics with a vibrant, durable powder coat finish
• Designed to withstand the demanding conditions of heavy-duty diesel applications

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 choice ensures the pipe remains structurally sound under extreme heat and pressure, unlike OEM rubber hoses that degrade over time. The powder coat finish not only adds a layer of protection against environmental factors but also provides a visually appealing upgrade to the engine compartment.

Precision engineering guarantees that the pipe matches the OEM dimensions and mounting points, allowing for a seamless installation without the need for modifications. The design maintains optimal coolant flow to support efficient engine cooling and prevent overheating during heavy-duty operation.

Installation & Fitment

Installation is straightforward, as this upper coolant pipe is a direct replacement for the factory rubber hose on 2013–2018 Ram 2500 and 3500 trucks with the 6.7L Cummins engine. It is intended for use with OEM RAM radiators; aftermarket radiators with differing inlet locations may cause fitment issues. No special tools or modifications are required, making it a convenient upgrade for both professional mechanics and experienced DIY enthusiasts.
