Wehrli Upper Coolant Pipe

2013–2015 Ram 2500 / 3500 6.7L Diesel

Part #: WCF100867-SBO

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 dual radiators, this aluminum pipe eliminates the common failure points associated with the OEM rubber hose and plastic connector, which are prone to leaks and deterioration over time. This upgrade offers enhanced durability and reliability, ensuring your cooling system maintains optimal performance under demanding conditions.

Ideal for Ram owners seeking a long-lasting, maintenance-free solution, the Wehrli Upper Coolant Pipe provides peace of mind by preventing coolant leaks that can lead to engine overheating and costly repairs. Its powder-coated finish in Sparkle Bomber Orange not only adds corrosion resistance but also a distinctive appearance under the hood.

• Constructed from high-quality aluminum for superior strength and heat resistance
• Features an integrated Y-connector designed specifically for OEM Ram dual radiator systems
• Replaces the OEM rubber hose and plastic connector prone to cracking and leaks
• Powder-coated in Sparkle Bomber Orange for corrosion protection and visual appeal
• Direct bolt-on replacement with no modifications required for factory dual radiator setups
• Compatible with OEM RAM dual radiators; aftermarket radiator fitment may vary
• Replaces MOPAR part numbers 52014722AD, 52014722AB, and 52014722AC
• Improves cooling system reliability under heavy-duty and towing conditions

Construction & Design

This upper coolant pipe is precision-crafted from lightweight yet robust aluminum, chosen for its excellent thermal conductivity and resistance to corrosion. The integrated Y-connector is engineered to match the exact specifications of the OEM dual radiator inlet locations, ensuring a perfect fit and leak-free seal. The entire assembly is finished with a durable powder coat in Sparkle Bomber Orange, providing additional protection against rust and environmental damage while enhancing the engine bay’s aesthetics.

The design eliminates the weak points found in the factory rubber hose and plastic connector, which are susceptible to heat-related degradation and mechanical stress. By upgrading to this aluminum pipe, you gain a more reliable coolant pathway that withstands the rigors of heavy-duty use and extreme temperatures.

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 special tools or modifications are required when used with OEM dual radiators. However, owners with aftermarket radiators should verify inlet locations, as variations may affect fitment.

Simply remove the original rubber hose and plastic connector assembly and install the Wehrli aluminum upper coolant pipe using the existing mounting points and clamps. This upgrade helps prevent future coolant leaks and reduces maintenance concerns related to the cooling system.
