    Features & Details

    • Keeps Engine Running Cooler
    • Great for Modified Mustangs
    • Fits 1996 to 2004 4.6 GT, Bullitt, Mach 1 and Cobra
    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 154° fahrenheit (68 C) than the standard OEM factory thermostat 190° fahrenheit (88 C) 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 1996 to 2004 Mustangs equipped with 4.6L V8 engine, including the GT, Bullitt, Mach 1, and SVT Cobra.

    Does the gasket need to be removed for installation? If not, the thermostat sits on top of the manifold and not inside, as needed?

    • If you check out the installation guide on the product page under the Installation Info section, you will see that there is a new O-ring with the thermostat that will sit in the manifold.

    I have a 97 cobra that I'm looking to help make it run a little cooler. I read in a magazine from Sean hyland that 4.6L DOHC like to run around 170-180 degrees. If this is a 160 degree thermostat will it make it run too cool to where a tune will be needed? I'm afraid it will keep the engine too cool when you're driving and keep it in it's "warm-up" mode.

    • The Mishimoto Racing Thermostat will not require a tune, however your best benefits will come when using a tune to modify parameters such as fan on/off times to match the new cooler thermostat.

    Will it fit a 2001 v6

    How does this thermostat effect the heating system in the winter time, will the interior still get as hot?

    • The car will still heat up to the full operating temperature, however, if the thermostat is open, and a high volume of air is passing through the radiator, the coolant flowing through the heater core will be at a lower temperature. If a lesser amount of air is passing the radiator, the heat in the coolant will not dissipate as easy, and the coolant will be a higher temperature.

      Perfect for upgrading or replacing OEM

      The thermostat was super easy to install and I’ve been having overheating issues in the past so I upgraded most my cooling system. When I opened the box it came with the thermostat and gasket. The gasket looks kinda weird and didn’t really set well within the housing, so I just threw the gasket to the side and used a basic O-ring gasket and it’s perfect. The moment the car gets to operating temps and I start driving a bit harder the temp gauge will raise a bit and then just drop to right above the O. Loving it.

      Not an exact fit for the Cobra

      If you want to use this on the Cobra you have to modify the provided gasket. I used a razor blade, but in the end it worked and dropped the coolant temp as expected.

      Runs a lot cooler

      Did the thermostat while upgrading the cooling system. Recommend stopping and grabbing a new o ring because the one that comes does not fit. Runs a lot cooler now.

      Excellent, keeps you cooler!

      Nice Quality Thermostat. Comes with an odd seal though, and I was not sure how to make it work. However, I bought the Ford Thermostat O-ring and it worked perfectly. Installation was not hard, but a little tougher on a 99 Cobra because the thermosat is hanging by hoses at the bottom of the radiator, right side. After draining the coolant from the radiator and expansion tank. I decided to forgo the drain plugs in the block (hard to get to) and just drain out where the thermostate sits. There was still a lot in the hoses. Lossened the bolts on the thermostat housing and drained all I could. When I pulled the thermostat out it gushed a lot of coolant so have a catch pan under it.

      it's a great product that fit perfectly and does what it says, keeping the coolant flowing to keep those temperatures down when your putting your car under a lot of stress. thanks American muscle for having great products!

      Runs cooler but had to reuse old gasket

      Happy with the reduced temperature. Disapointed that the O-ring is no where near the size needed to fit. I ended up re-using the old gasket against my better judgement but I needed the temps to come down.

      The Coolest Stang Around

      I have to say that I am very pleased with the Mishimoto thermostat. It works just like they said that it would. My 1998 mustang gt idle at normal temperature range but when I begin driving it drops my temperature down in a very safe zone. I needed a thermostat that would allow my stang to run cooler since my spark and timing is advanced. And it doesn't interfere with my heat at all. Once again a great product and brand from American Muscle. Highly recommended..

      No difference

      I installed this on a 98 GT and I see no change in engine temperature at all. The engine is as hot as it ever was. I don't know how this product can have so many good reviews.. It's a waste of money.

      Mishimoto Racing Thermostat

      I needed a new thermostat since I overheated a couple of times, so I went with this one. I haven't overheated since installing it so it's doing its job. Engine bay does seem to stay a little cooler. I'm not sure if I'm the only one having this problem but since install it's been throwing codes like crazy. Hopefully a new tune will fix that. Good replacement part, go ahead and get one.
