Wehrli 04.5-07 Cummins 5.9L Coolant Tank (OEM Placement) - Gloss White

When you're looking to clean up the engine bay on your 2004.5-2007 Dodge Ram 2500 with the 5.9L Cummins, replacing that faded, yellowed plastic coolant reservoir is a great place to start. This fabricated aluminum coolant tank from Wehrli Custom Fabrication mounts right in the factory location, making the swap straightforward.

This tank is built from aluminum and then finished with a durable gloss white powder coat, giving your engine bay a much sharper look. It comes with a black anodized billet aluminum cap and a billet coolant level sight glass so you can easily check your fluid level. It uses the stock mounting points and installs with basic hand tools, so you won't need any special modifications to get it fitted. This tank is designed to replace Mopar part numbers 55056493AA and 55056493AB.

Keep in mind that this tank is designed for the 2004.5 and later models. If you have an earlier 2004 or 2003 model, the coolant tank is mounted differently on the radiator core support, and this tank will not fit.
