If you’ve got a 1999-2005 Ford with the 7.3L diesel—like a Lariat or Cab and Chassis—you know that plastic coolant tanks can get brittle and crack over time.
This one’s a performance upgrade: an aluminum alloy overflow tank that’ll outlast the factory plastic.

It’s painted silver, so it looks clean under the hood, and it includes a cap and a level window so you can keep an eye on your coolant.
Dimensions are 420mm long, 90mm wide, 230mm high—fits right in place of the stock unit with a bolt-on install.

Interchanges with part numbers F6DZ8100A, F6DZ8100-A, 2C3Z8A080AA, and 2C3Z-8A080-AA.
The aluminum construction helps dissipate heat better than the stock plastic, which is always a plus in a turbo diesel.
Brand new, unbranded but solid, and comes with a 1-year warranty.

Perfect if you’re chasing reliability or just want a cleaner engine bay.
So if your factory tank is looking rough, swap it out for this aluminum one and never worry about cracks again.
