Answers :

Overheating is caused by:
\015\0121. loss of coolant
\015\0122. lack of circulation of the collant
\015\0123. lack of air flow through the radiator
\015\012A bad thermostat would account for #2. I assume it was overheating when you replaced the thermostat?
\015\012Here are a couple tests to see what is going wrong.
\015\012As the car comes up to temp, you should see a couple things happen.
\015\012 a. The temp gauge should raise at least to a normal range
\015\012 b. once the engine reaches a certain temperature, the computer should tell the electric fan to come on. If your car overheats without the electric fan coming on, then that is a problem. If the fan does come on, you should feel (be carefull not to stick your hands in the wrong place), hot air blowing all over the engine from the fan(s). If that air is not real hot, you could have a restricted radiator.
\015\012 c. The fan(s) should cycle on for a minute or two and then turn off. The temperature may need to be around 200 degrees before the fan actually comes on. That depends on your car.
\015\012If there is a restriction in the cooling system (clogged radiator), preventing the proper amount of collant to circulate, that may be the problem (Not Likely)
\015\012There is a temperature sensor somewhere on the engine to tell the computer how hot the engine is getting. That could be defective. Look for it and follow the wires to see if there is broken wire of the sensor became unplugged.
\015\012See if there is plenty of heat from the heater? This indicates that there is coolant circulating.
\015\012Hope this helps.
Check if the car consumes to much coolant. If it does check for leaks on the radiator, the hoses, the water pump and the radiator cap. If it does not leak check if the radiator fan turns on when you have the thermostat unplugged. If it does not it may be a bad fan or a bad relay.
