Features & Details

  • Stronger Than Factory Plastic Tank
  • Direct Fit Replacement
  • Fabricated Aluminum Construction
  • Fits 1986 to 1993 5.0 V8 Mustangs
High Performance. Moroso has designed a high performance direct bolt in fabricated aluminum coolant tank to replace the weak stock plastic coolant tank that is prone to failure in high temperature race situations.

Durable Construction. Manufactured from high strength lightweight aluminum this Coolant Expansion Tank is much stronger and better looking than the stock plastic tank. And it features integral mounting bracket and fittings to ensure a secure fit.

Application. This Moroso Aluminum Coolant Expansion Tank is designed to fit the 1986 to 1993 LX and GT Mustangs equipped with the iconic 5.0L V8 engine. Reuses the stock cap.

Technical Note. This Radiator Overflow Tank does not include the cap or the low coolant sensor, it is designed to reuse your own. 1986-1989 Mustangs will need a 1990-1993 style low coolant sensor, the 1986-1989 style sensor is not compatible with this coolant tank.

      Does anyone know what billet cap will fit this tank?

      • The Moroso Coolant Expansion Tank uses the OEM factory cap.

      does the oem coolant cap with sensor fit on the moroso coolant expansion tank

      • Yes, when I first looked at it I was confused. But there is a single twist lock to take it off and put it on, the whole cap, mount, and sensor. I would recommend a good cleaning of the original parts though, when I installed the tank and placed the cap it looked dirty. Scrubbed the cap with soap and water, armor all, stand back about two feet, and pat yourself on the back. Awesome!

          Nice Tank But......

          Tank was a perfect fit to the car but on my 1988 the coolant sensor tube will not fit in side the tank.

          overflow tank of badassery

          I have seen many other tanks. None compare to the fit and beauty of this piece. The welding alone is unreal. You wont be disappointed.

          Great product but not quite exact fit...

          The stock plastic tank has 4 mounting holes. However, this Moroso tank only has 2. It is missing the two that should be on the bottom. With my aftermarket aluminum radiator and electric fans I cannot use the middle bolt hole and can only use the one top and two bottom so without the two bottom holes having just the one top hole was a problem. Luckily a local welding shop was able to quickly weld a strip of aluminum to the bottom which I drilled out two holes to match the stock so I could bolt it on properly.

          Very happy

          It would have been better if MOROSO would have had the tabs welded on to fit the fan guard aND nice aluminous mouting screws...also nice if it would have come with a custom MOROSO cap...other than that product is very nice

          not great but not bad

          as shown in the pictures this tank doesn't include any type of brackets or a new hose but that's acceptable since you know it before you buy it but still a bit deceiving. The oem cap works just fine, no issues there. since it does not include a hose the oem hose is too short also so I had to go get a new one. what I found annoying is that the hose on this tank is bumping against the larger lower radiator hose and you have to play around to reroute the overflow tank hose. kind of deceiving to get this type of issues from a big brand name like moroso. none the less I got it installed but it could have been easier for a simple tank. what took me a lot of time is running around to put the hardware pieces together to install this tank.

          It looks good

          This tank only uses the 2 bolts to mount it down to the fan shroud. It doesn't use the clips at the bottom like the stock one does. The worst thing about this design is that the hose that connects from the bottom of the reservoir tank to the filler neck of the radiator, is not placed well. It is placed so it runs right into the lower radiator hose. You have to route the reservoir tank hose under the lower rad hose and then run it up the filler neck. And of course the old line isn't long enough. Not sure what cap fits this tank....it is not the stock one. Have not had the time to figure that one out yet.

            This tank is supposed to utilize the stock cap. If you are having an issue with yours, please give us a call and we can help figure out what is going on.

          Very Good

          Looks great, a direct fit over your plastic one. I would advise taking off your fan shroud to put it on, other wise your AC compressor gets in the way.

          High Quality Item

          Im so glad I got this as my original plastic one had a crack. You may need a new tube to connect the tank as the stock one is a little short.
