    Features & Details

    • Keeps Engine Running Cooler
    • Great for Modified Mustangs
    • Fits 1986 to 1995 5.0 V8 Mustangs
    Run Cooler. The Mishimoto Ford Mustang Racing thermostat promotes greater cooling efficiency throughout your Pony's engine and significantly lowers high engine temperatures produced by modified and forced induction applications.

    More Power. The Mishimoto racing thermostat opens up at a lower temperature (68°C, 154°F) than the standard OEM factory thermostat (88°C, 190°F), allowing the coolant to flow through the engine block sooner reducing and maintaining cooler engine temperatures helping to produce more power.

    Application. This Mishimoto Racing Thermostat is specifically designed for use on the 1986 to 1995 GT or Cobra Mustangs equipped with 5.0L V8 engine.

    does this thermostat make the car to heat up faster on a cold around 25 to 30 degree


    • The Mishimoto Racing Thermostat (86-95 5.0L) provides greater cooling efficiency which will significantly lower high engine temperatures. It is going to keep the engine cooler. It will not cause the engine to heat up faster.

      Good thermostat

      My 1995 GT was running a bit hot after installing 3.90 gears (cruising at 2800-3000rpm on the highway) so I installed this thermostat and it fixed the problem!

      Great thermostat

      This thermostat is a must when your mustang is producing some power with aftermarket parts. I'm very satisfied with it because it keeps my mustang cool when I'm driving long distances.

      Good Product

      I purchased this thermostat when I was noticing that even with my aluminum radiator my engine was stil running a little warmer than I would have liked with my mods, installed this in less than an hour and fixed the problem.

      Great Product, Good Price

      My car was heating up horribly, definitely wouldn't make it through summer, so I bought this thermostat. Did the trick. I've done some mods and still had the stock one, and it just wasn't cutting it. Put the new one on and the car stays cool on the hottest of days. It is a little price-y, but it is name brand. And, it does work extremely well. I would definitely recommend this product, and installation was a breeze.

      Racing Themostat

      I just replaced my stock radiator with an SR Performance Aluminum Radiator and replaced the thermostat with this Mishimoto Racing Thermostat and installed a new water pump in my 93 all stock GT with 100K miles on it. It runs much cooler now. I plan on adding some mild upgrades that should add another 40 to 50 horse power to the car this new coolant system I chose should be good enough to keep me cool enough
