AnswerI have a 93 sunbird. The thermostat is located right under the radiator cap. Wait for the car to cool down. remove the radiator cap. you will see an aluminum bar pull the bar out and that is your thermostat. top off the coolant before installing the new thermostat. put the new thermostat in. push on it a little bit to make sure you get a good seal and then replace the radiator cap. That is all there is to it. the thermostat on these cars is really easy to change and i have done it several times.
yes the sunbird is front wheel drive
NO
I just had my head replaced and cracked my thermo housing when trying to find the leak prior to. The dealer wanted $88.00 for the thermo housing, it is a dealer only part. Thermostat is only about $10.00.
I found out where it goes. Open your rad cap and just drop it in. I hope this helps someone else. Annette
