Chevrolet 5500 Coolant Tank Kit - Wehrli - Fabricated Aluminum - WCFab Grey - `19-`27. A direct OEM-location replacement coolant reservoir built from fabricated aluminum and finished in WCFab Grey.

Engineered for 2019+ L5D Duramax 4500/5500/6500 platforms, this tank addresses two common issues with the factory plastic unit: yellowing/clouding over time and a non-replaceable low-coolant sensor that can trigger false warnings. The WCFab design uses a durable float-type sensor that can be serviced independently, plus a billet sight glass and black anodized billet cap for quick checks and long-term serviceability. It mounts in the stock location, includes installation hardware and an overflow hose, replaces GM part numbers 84257137, 84214124, 84138913, and 84174037, and is made in the USA.
