      • Keeps Engine Running Cooler

      • Fits 1986 to 1995 5.0 V8 Mustangs

      Description

      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.

        Keep it running cool

        Lets just say rock cold. Don't mess around with those bottles that say it will lower the temps. Just buy the thermostat. My temps are rock cold dead on 160.

        Major temp change

        Installed new Mishimoto radiator, Liquid Chill coolant and the racing thermostat. These items in combination made a major change in operating temp of my 87 supercharged Saleen on hot summer days and in heavy traffic, never gets even close to overheating.

        Great

        My 95 GT was over heating. After I did a full flush of the engine and radiator along with installing this thermostat it runs great.

        Fancy thermostat

        I don't drive the car that often to really notice a difference, however, I am glad I replaced it.

        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

      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.
