      High Performance Replacement. The factory two piece plastic coolant expansion tank is prone to failure especially in high temperature situations, that is why Moroso developed their Aluminum Coolant Expansion Tank to be a one piece design making it perfect for high temperature street and race applications.

      Durable Construction. Manufactured from high strength lightweight aluminum, this Coolant Expansion Tank features a 6061-T6 billet aluminum filler neck making it much stronger and better looking than the factory two piece plastic tank. This expansion tank also has integral mounting bracket and fittings to ensure a secure fit when installed.

      Built-in Overflow Reservoir. This Moroso Coolant Expansion Tank meets the requirements of both the NHRA and SCCA by having a built-in one pint overflow reservoir, making it perfect for race applications.

      Application. This Moroso Aluminum Coolant Expansion Tank with Overflow Reservoir is designed for use on all 2005 to 2010 Mustangs including the V6, GT, Bullitt and Shelby GT500 models. Requires the use of a "seat and spring" style Radiator Cap, sold separately.

        Moroso Overflow 2010 Mustang GT

        Easy bolt on. Looks great will post pic when total build is done. Some notes. The Cap you want is Moroso cap part Number is 63316. If AM hasn’t got it, I actually found them for sale from an RV place. It’s just a Ford Radiator spring type cap. 14|18 PSI. Also note. You can NOT fit all 3 Moroso tanks Radiator overflow, intercooler, and power steering tank in the front of the car! I took the stock Whipple tank, sand blasted it, and polished it a little. Love the looks!

        Drop the plastic containers and get aluminium.

        Seriously, your car engine looks meaner, more finished and I can't tell you how many people have stopped to take a third look at car shows. Easy to polish and get a nice shine. Very happy with the entire set.

        Excellent construction, looks great!

        My friends that know how to weld all say that the people who put these tanks together really know what they're doing. All the Moroso stuff is worth the money. Looks super sweet under the hood! Easy install. Buy a suction gun and a hose clamp tool, if you don't already have them.

        NHRA pre-inspection PASS

        This is an excellent expansion tank with a 9 ounce secondary overflow separate from the main chamber required by NHRA rules It is between a brushed and A polished finish it does not come with the hose shown to send fluid to the Overfall overfill tank or cap American muscle carries a 16 pound radiator cap if you're in a pinch any cap off a small block mid 80s Chevy will work but your stocking cap will not work Installation was a breeze about 15 minutes take the time to siphon existing anti-freeze out siphon pumps are about three dollars at Pep Boys overall I am very satisfied with the tanks Quality just like everything else I purchased from American muscle
