Wehrli Custom Fabrication WCF100203-CT Coolant Tank Kit with Battery Box Candy Teal

The Wehrli Custom Fabrication WCF100203-CT is a fabricated aluminum coolant reservoir and battery box kit finished in a striking Candy Teal powder coat. This kit mounts in the OEM location on the 6.7L Power Stroke, replacing the factory plastic coolant tank and failure-prone OEM battery tray with a durable, precision-built aluminum assembly.

The integrated aluminum battery box enclosure for the driver-side battery preserves the critical structural support required for intercooler mounting points — an important consideration when running either OEM or aftermarket intercoolers. All factory hose connections are retained, allowing for a clean, straightforward installation using basic hand tools with no additional modifications required.
