Over heating car changed thermostat,acting really weird?
Most of these cars have an electric fan that helps keep the engine cool, check to see if its functioning properly.
It could be a bad thermostat, or one rated higher than what your car is made for. Usually 180 deg is safe. You could have air in the system, check this by starting the car cold and taking the radiator cap off and let it run for a few minutes. Keep an eye on your coolant level, if it goes down, add anti-freeze. After about 5-7 minutes and your coolant level looks good, replace the cap %26amp; check your resevoir %26amp; make sure it is up to the warm/hot line. After it is %26amp; the system is closed back up, shut the car off for 5 minutes. Then start the car %26amp; take it for a drive, this should've taken care of the problem. If it doesn't, you might want to have you water pump checked out. Good luck.
I had a similar issue in my F150 p/u. Turned out to be two things...a vacuum check valve and a %26quot;tired%26quot; diaphram on an airflow gate (door) under the dash. replaced them and now they work like new!
If you want to be on the safe side, take it to a different mechanic (a competent, conscientious one) and have him replace the Thermostat again, with a high quality brand, and have him check the fan too. Make sure there is heat coming out of the heater, and the temperature is stable before you leave the parking lot.
