Wehrli Custom Fabrication WCF100542-CRO OEM Placement Fabricated Aluminum Coolant Tank Kit - Chrome

The Wehrli Custom Fabrication WCF100542-CRO is a fabricated aluminum coolant tank kit finished in a Chrome powder coat, designed as a direct OEM-location replacement for the 2004.5–2007 5.9L Cummins. This kit lets you eliminate the aging, yellowed factory plastic coolant reservoir and replace it with a precision-welded aluminum tank that improves both underhood appearance and long-term durability.

Engineered to use the factory mounting points, this coolant tank installs with basic hand tools and requires no modifications on a stock truck. The chrome powder coat finish delivers a head-turning, show-quality look under the hood while standing up to the heat and humidity of the engine bay.

Kit Includes:

• Fabricated aluminum coolant tank – precision-welded construction for superior durability over OEM plastic
• Black anodized CNC-machined billet aluminum cap – premium replacement for the factory plastic cap
• Installation hardware – all necessary mounting hardware included
• Chrome powder coat finish – bold, show-quality appearance

Key Features:

• Direct-fit OEM mounting location – no cutting, drilling, or modifications required
• Uses factory mounting points for a clean, stock-style installation
• Compatible with stock and modified 2004.5–2007 5.9L Cummins trucks
• Replaces MOPAR OEM part numbers: 55056493AA and 55056493AB
• Made in the USA by Wehrli Custom Fabrication

Note: Not compatible with 2003 or early 2004 Dodge Ram 2500/3500 models that have the coolant tank mounted on the radiator core support.
