Wehrli Upper Coolant Pipe

2013–2015 Ram 2500 / 3500 6.7L Diesel

Part #: WCF100867-IP

Overview

The Wehrli Upper Coolant Pipe is a premium replacement part designed specifically for 2013 to 2015 Ram 2500 and 3500 heavy-duty trucks equipped with the 6.7L Cummins diesel engine and dual radiator cooling systems. This aluminum upper coolant pipe with an integrated Y-connector replaces the factory rubber hose and plastic connector assembly, which is prone to leaks and premature failure. By upgrading to this durable, powder-coated aluminum pipe, owners can improve cooling system reliability and reduce the risk of coolant leaks that can lead to engine overheating and costly repairs.

Ideal for Ram owners who demand long-lasting performance and want to maintain optimal engine cooling under heavy-duty conditions, this part is engineered to fit seamlessly with the OEM dual radiator setup, ensuring proper coolant flow and system integrity.

• Improves cooling system reliability under heavy-duty and high-stress conditions
• Corrosion-resistant finish for long-lasting appearance and performance

Construction & Design

The upper coolant pipe is precision-machined from lightweight, durable aluminum, providing enhanced resistance to heat and pressure compared to the original rubber and plastic components. Its integrated Y-connector is engineered to maintain proper coolant flow between the engine and dual radiators, ensuring efficient heat dissipation. The powder-coated finish not only adds corrosion resistance but also offers a visually appealing upgrade, with options like Illusion Purple that complement your engine bay’s aesthetics.

Every aspect of the design focuses on durability and reliability, addressing common failure points found in the OEM parts to provide a maintenance-free solution that lasts.

Installation & Fitment

This upper coolant pipe is designed for a direct bolt-on installation on 2013–2015 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine and factory dual radiator setup. It replaces the OEM rubber hose and plastic connector without requiring any modifications. However, fitment is optimized for OEM dual radiators; aftermarket radiators with different inlet locations may cause installation challenges or require additional adjustments.

Installation can typically be completed with basic hand tools and moderate mechanical experience. It is recommended to inspect all coolant system components during installation and replace any worn hoses or clamps to ensure a leak-free system.
