Wehrli 04.5-07 Cummins 5.9L Coolant Tank (OEM Placement) - Candy Red

This kit gives you a custom-fabricated aluminum coolant tank in a sharp candy red powder coat finish, designed to replace the aging plastic reservoir in your 2004.5-2007 Dodge Ram 2500 or 3500 with the 5.9L Cummins engine. It includes a black anodized billet aluminum cap, a billet coolant level sight glass, and all the necessary mounting hardware. This tank uses the factory mounting points, so it fits right in the original location without needing any other modifications to your truck.

Swapping out the factory plastic tank for this aluminum version not only dresses up your engine bay but also offers a more robust solution. The aluminum construction is well-built and finished with a durable custom powder coat that resists fading and corrosion. The included billet aluminum cap and sight glass add a clean, finished look that you won't find on stock trucks. Installation is straightforward, requiring only basic hand tools, making it an accessible upgrade for many owners.

This coolant tank is specifically designed for the 2004.5 through 2007 model years of the 5.9L Cummins. It will not fit earlier 2003 or early 2004 models that have the coolant tank mounted differently. This part replaces MOPAR part numbers 55056493AA and 55056493AB.
