Wehrli 04.5-07 Cummins 5.9L Coolant Tank (OEM Placement) - Bengal Blue

If you're working on your 2004.5-2007 Dodge Ram with the 5.9L Cummins engine, this fabricated aluminum coolant tank from Wehrli is a solid option for replacing that aged, yellowed plastic reservoir. It's designed to mount right in the factory location, so you won't need to modify anything on stock trucks. This upgrade not only looks sharp but also ensures you have a reliable coolant overflow tank.

This tank is made from fabricated aluminum and then finished with a durable Bengal Blue powder coat, giving your engine bay a custom look. It comes with a black anodized billet aluminum cap and a billet coolant level sight glass, so you can easily check your coolant level. All the necessary mounting hardware is included, and it installs using basic hand tools, fitting directly onto the OEM mounting points.

This tank is specifically for the 2004.5 through 2007 models of the 5.9L Cummins. It won't fit earlier 2003 or early 2004 trucks where the coolant tank is mounted on the radiator core support. It's a direct replacement for MOPAR part numbers 55056493AA and 55056493AB.
