Wehrli Upper Coolant Pipe

2013–2015 Ram 2500 / 3500 6.7L Diesel

Part #: WCF100867-RED

Overview

The Wehrli Upper Coolant Pipe with Y-Connector is a direct replacement for the factory rubber upper coolant hose found on 2013 to 2015 Ram 2500 and 3500 HD trucks equipped with the 6.7L Cummins diesel engine and dual radiator setup. Designed specifically for vehicles with OEM dual radiators, this aluminum pipe eliminates the common failure points associated with the original plastic connector and rubber hose, which are prone to leaks and premature wear. Finished in a durable powder coat, this component not only improves reliability but also adds a clean, custom look to your engine bay.

Ideal for Ram owners seeking a long-lasting, maintenance-free cooling system upgrade, the Wehrli Upper Coolant Pipe ensures optimal coolant flow and system integrity under demanding conditions.

Key Features

• Constructed from high-quality aluminum for superior strength and heat resistance
• Features an integrated Y-connector designed specifically for dual radiator configurations
• Powder coated finish available in multiple colors for corrosion protection and aesthetic appeal
• Direct bolt-on replacement for OEM rubber hose and plastic connector assembly
• Eliminates common coolant leaks caused by factory plastic connectors
• Compatible exclusively with OEM Ram dual radiator setups to ensure proper fitment
• Replaces MOPAR part numbers 52014722AD, 52014722AB, and 52014722AC
• Improves cooling system reliability and longevity under heavy-duty use

Construction & Design

The Wehrli Upper Coolant Pipe is precision-machined from durable aluminum, providing excellent resistance to heat and pressure compared to the factory rubber hose and plastic components. Its integrated Y-connector is engineered to match the exact specifications of the OEM dual radiator system, ensuring seamless coolant flow without restrictions or leaks. The entire assembly is finished with a high-quality powder coat that protects against corrosion and wear, maintaining both performance and appearance over time.

This robust construction is ideal for heavy-duty diesel trucks that demand reliable cooling performance during towing, hauling, and extended operation.

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 diesel engine and dual radiator setup. No modifications are necessary when used with OEM dual radiators. However, fitment with aftermarket radiators may vary if their inlet locations differ from factory specifications, so compatibility should be verified prior to installation.

The powder coated finish and durable aluminum construction provide a long-lasting upgrade that reduces the risk of coolant leaks and system failures common with the original plastic and rubber components.
