Wehrli Aluminum Upper Coolant Pipe
2013–2018 Ram 2500 / 3500 6.7L Diesel
Part #: WCF100517-RED
Overview
The Wehrli Aluminum Upper Coolant Pipe is a premium replacement part designed specifically for 2013 to 2018 Ram 2500 and 3500 heavy-duty trucks equipped with the 6.7L Cummins diesel engine. This component replaces the factory rubber upper coolant hose that connects to the radiator inlet, offering a durable and reliable upgrade for your cooling system. Powder coated in vibrant red, this pipe not only enhances durability but also adds a custom look under the hood.
Ideal for diesel truck owners seeking improved longevity and a clean, professional appearance, this aluminum coolant pipe is engineered to maintain OEM fitment and function when used with the original Ram radiator. It is a direct replacement for several Mopar part numbers, ensuring compatibility and ease of installation.
Key Features
Designed with quality and performance in mind, the Wehrli Aluminum Upper Coolant Pipe offers the following key features:
- Constructed from high-grade aluminum for superior strength and heat resistance compared to OEM rubber hoses
- Powder coated finish in red for corrosion resistance and enhanced engine bay aesthetics
- Direct OEM replacement, compatible with factory Ram radiators for a precise fit
- Replaces multiple Mopar part numbers including 68166469AC, 68166469AA, 68166469AB, and others
- Improves cooling system reliability by eliminating the common failure points of rubber hoses
- Maintains proper coolant flow and pressure to support optimal engine temperature management
- Engineered specifically for 6.7L Cummins diesel engines in Ram 2500 and 3500 trucks
- Powder coating provides long-lasting protection against environmental wear and tear
Construction & Design
The upper coolant pipe is precision-crafted from lightweight yet durable aluminum, chosen for its excellent thermal conductivity and resistance to cracking or swelling under heat and pressure. The powder-coated finish not only protects the pipe from corrosion but also resists chipping and fading, ensuring it maintains its vibrant red color over time. This robust construction helps prevent common issues associated with OEM rubber hoses, such as leaks, bulging, or premature failure.
Engineered to match the exact dimensions and mounting points of the original equipment, the pipe ensures a seamless fit without the need for modifications when installed with the OEM radiator. The design supports consistent coolant flow, contributing to efficient engine cooling and overall vehicle reliability.
Installation & Fitment
Installation is straightforward and designed to be a direct swap with the factory upper radiator hose on 2013–2018 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine. No special tools or modifications are required when used with the OEM Ram radiator. However, fitment may vary if aftermarket radiators are installed, as inlet locations can differ from factory specifications.
For best results, ensure the cooling system is properly drained before removal of the old hose. The aluminum pipe installs using existing clamps and mounting points, providing a secure and leak-free connection.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
