The Wehrli fabricated aluminum coolant tank kit for 2004.5–2007 5.9L Cummins swaps the plastic reservoir for a powder‑coated aluminum tank that mounts in the OEM location and uses factory mounting points. It includes a black anodized billet cap, billet coolant level sight glass and installation hardware. The gloss white finish updates the engine bay and the tank installs with basic hand tools; not compatible with 2003 or early 2004 models.
