Can you see the cooling fans come on? When the engine gets to 212 degrees the fans should come on. To test the fans, with the engine running turn the A/C on high, the fans should come on .
The system also has a 212 switch that screws into the intake manifold. This is what turns on the fans with no A/C.
I hope this helps you.

I would like to help you, hopefully there isn't any major problems I.e. blown head gasket. This vehicle is equipped with electric cooling fans... so the first thing we need to to check is that the fans are turning on. If they are not this is the cause of your overheating. If this is the case there are a couple of things you can check. fuses, fan relays and the obvious any wiring going to the fans not plugged in or bare shorting out causing your fuse to blow. I hope this helps and that it is not a blown head gasket

Car seems to be heating up dont know if it can be a stuck or bad thermostat

thats a good possibility, though most thermostats get stuck open, not closed. check the coolant level to make sure its ok, a lot of times the water pump will go bad, and allow air to seep in causing air pockets, thus making the vehicle overheat, also is it blowing good heat?? might be heater core leaking.

My jeep grand cherokee started overheating at idle

try the water pump - first - make sure the radiator is really full - take the cap off cold and fill - if it looks full - start and run 8 minutes or so - then fill it up - look at ur fan belt - is it tight - tight is about how much pressure u use to make a firm hand shake with little movement - any movement over about an inch is loose - when the jeep warms up the belt can slip and not even make a noise - - new materials don't always squeal. - then be sure ur water pump is ok - they go slowing - the fins wear down - one more thing is the radiator - u don't say how many miles or what maintenance schedules you have or not so that's it for now

90 subaru legacy overheats, wheres the thrmostat

When a car overheats it's rarely the thermostat. They just don't go bad that often. If it overheats when you idle a lot, it's the fan and with electric fans, it's almost always the fan motor. But to find the thermostat, follow the top radiator hose to the engine and there it is.

1989 Ford Escort GT overheating

Sounds like to me it would be your water pump before a heater core. When the water pump goes out, it stops pumping the coolant through the system which is what would cause it to still overheat even with the thermostat out. Change the water pump and you should be good. Let me know if you have any other questions. Thanks for using FixYa!
