Remove the Stat and see what happens to your overheating problem
Do you hear the cooling fan? When engine is idling?

If u mean the thermostat I will do that and see what happens but I do know it works I put it into a pot and boiled it and it did open

I did take out the thermostat and filled the raidiator drove the car I do get heat now and I notice the temp gauge stays in the cold will that cause a problem and if not is it ok to leave it that way during the summer too?

Its your choice-Remember the computer has to read the temperature from the coolant temperature sensor for other purposes such as fuel delivery and tranny shifting/overdrive etc. Best bet is just get another T-Stat with the correct Temperature for your model.
The final decision is yours-Good Luck

Should be on the heater hose before it goes in the heatercore.
