Wehrli 04.5-07 Dodge 5.9L Cummins OEM Placement Coolant Tank Kit - WCFab Grey

This fabricated aluminum coolant tank from Wehrli Custom Fabrication is built to replace the stock plastic reservoir on your 2004.5-2007 Dodge 5.9L Cummins. The original plastic tank can become brittle and discolored over time, but this aluminum unit offers a more robust and visually appealing alternative that mounts directly in the factory location using OEM points. It’s a solid upgrade for dressing up your engine bay while ensuring reliable coolant containment.

The tank itself is constructed from durable aluminum and finished with a WCFab Grey custom powder coat, which helps protect it from corrosion and gives it a clean, finished look. It comes complete with a black anodized billet aluminum cap, a billet coolant level sight glass for easy monitoring, and all the necessary mounting hardware. This kit is designed to be a direct fit, meaning you won't need any other modifications to install it on stock trucks. Installation is straightforward, requiring only basic hand tools.

This kit is specifically designed for the 2004.5 through 2007 model years of the 5.9L Cummins engine. It will not fit earlier 2003 or early 2004 models where the coolant tank is mounted on the radiator core support. This Wehrli coolant tank is a well-built replacement for Mopar part numbers 55056493AA and 55056493AB.
