How To Change Thermostat On Mustang

Need to know how to change the thermostat on a Mustang? A faulty thermostat can make your Mustang overheat. The thermostat regulates the temperature of your car. If the thermostat is faulty, the car will not release coolant to cool down your car. Your car will overheat and will ruin your day. Changing a faulty thermostat on a Mustang is relatively easy, and you can do it yourself.

To change a thermostat on a Mustang, you will need:

  • A new thermostat
  • A Phillips screwdriver
  • A socket set
  • A putty knife
  • A razor blade
  • Radiator fluid
  • A bucket
  • A new clamp for your radiator
  1. Buy a new thermostat for your Ford Mustang at the auto parts store. The new thermostat will come with a new gasket. Check and make sure the gasket is included in the package. You need the new gasket. Buy new coolant. Buy a new clamp for your radiator.
  2. Drive your car home. Let your car cool down. Open the hood and secure it with the safety arm. Find the radiator hose that leads to the engine of your car. Drain the radiator fluid into a bucket under your car. There is a release on the bottom of the radiator.
  3. Remove the radiator hose from the radiator. Take a Phillips screwdriver and remove the clamp that holds the hose onto the radiator. There will be two bolts holding the radiator hose onto the engine. Remove the bolts with the appropriate socket. Place the bolts and clamp to the side. If the clamp is ruined, throw it away. The housing will pull out of the engine. Pull the housing out and remove the old thermostat. Clean the old gasket material out with your putty knife. Clean the area well because this is where your new gasket will go.
  4. Replace your new thermostat the same way you found the old thermostat. Put the gasket in the appropriate place. Put the housing back on your engine. Put the two bolts back in and tighten them.
  5. Reattach the radiator hose to the radiator. Use the new clamp because the old clamp is most likely ruined. Tighten down the clamp in the appropriate place on your radiator hose.
  6. Tighten the release nozzle on your radiator. Put new radiator fluid in your radiator. Start the engine and let the radiator fluid get soaked into the engine. Continue to add radiator fluid until the radiator is full. Put the radiator cap back on the radiator. Let the car run for a while and make sure the hoses are not leaking. Add radiator fluid to your car if you need too. Let the car heat up. The new thermostat will now tell your car to send radiator fluid to the engine to cool down the engine.
  7. Take the safety arm off your hood and let the hood down. Drive your Ford Mustang normally.
