Wehrli Custom Fabrication WCF100559-GB Upper Coolant Pipe Galaxy Blue

The Wehrli Custom Fabrication WCF100559-GB is a heavy-duty upper coolant pipe engineered as a direct upgrade over the factory plastic or OEM coolant routing components found on diesel trucks. Built in-house by Wehrli Custom Fabrication (WCF), this pipe is constructed from mandrel-bent aluminum tubing and finished in their signature Galaxy Blue powder coat for long-lasting corrosion resistance and a clean, show-quality appearance under the hood.

Wehrli Custom Fabrication is known for producing precision-fit components that eliminate the weak points of OEM cooling system parts. This upper coolant pipe is designed for a direct bolt-on installation, retaining factory connection points while providing improved durability and flow characteristics over the stock piece.

Key Features:

• Mandrel-bent aluminum construction for strength and optimal flow
• Galaxy Blue (GB) powder coat finish for corrosion resistance and aesthetics
• Direct OEM replacement fitment — no cutting or modification required
• Eliminates failure-prone factory plastic coolant pipe components
• Precision-manufactured by Wehrli Custom Fabrication in the USA
• Includes necessary hardware and/or couplers as applicable

This coolant pipe is an ideal upgrade for performance and towing builds where cooling system reliability is critical. The durable powder coat finish withstands the harsh under-hood environment and pairs well with other WCF components for a cohesive custom look.
