Wehrli Custom Fabrication WCF100644-RAW LML Duramax Twin Turbo Fabricated Aluminum Coolant Tank Kit Raw Finish

The Wehrli Custom Fabrication WCF100644-RAW is a fabricated aluminum coolant tank kit designed for twin turbo applications. This kit is finished in raw (uncoated) aluminum, making it ideal for builders who prefer to apply their own custom powder coat color or leave the natural aluminum appearance. The tank mounts on the passenger side fender and is a direct upgrade over the factory plastic coolant reservoir.

Key Features:

• Fabricated aluminum construction — durable upgrade over the OEM plastic coolant tank
• Raw aluminum finish — uncoated for custom powder coat or natural look
• Designed for twin turbo applications — mounts on passenger side fender
• Includes low coolant sensor — maintains OEM-style coolant level monitoring
• Complete kit includes cap, hoses, clamps, and fittings for a straightforward installation
• Made in the USA by Wehrli Custom Fabrication

What's Included:

• Fabricated Aluminum Coolant Tank
• Low Coolant Level Sensor
• Cap
• Hoses
• Clamps
• Fittings

Note: Twin turbo placement on the passenger side fender does not allow use of the passenger side battery in the OEM location — battery relocation is required.

WCFab coolant tank kits are a popular finishing touch for performance diesel builds, replacing the aging OEM plastic tank that can yellow, crack, or become contaminated over time.
