check to see if your cooling fan is working if so look at your radiator cap and make sure the cap gasket is not broken.AnswerThe easiest way to see if your fan motor it still working is to run the A/C in the car, this triggers the relay for the fan. If the fan works and the car still overheats you will most likely new a new Coolant Temperature Sensor. There are two of these sensors. One controls the temperature gauge on the dashboard. The other takes a direct temp. reading of coolant. It is in the front right side of your engine just below the valve cover, you will see two small wires leading to it underneath the air filter. Answersometimes when you loose some coolent like when you changed the thermostat you get an air pocket trapped inside the engine witch will cause the engine to overheat.you have to bleed the air out. AnswerThe most likely cause is the coolant sensor located in the cyl haed on the back of the engine It has a small 2 wire connector attached to it. Unplug the connector and see if there is any corrosion on it If there is you will need a ssensor and harness. If not change the sensor It's only 18$ Canadian from Saturn Stay away from aftermarket on this as they never work properly
it could possibly have either a blown head gasket or intake manifold gaskets leaking
thermostat is more than likely stuck shut from the overheat. Have to be changed.
I have a promblem with that too, my car would overheat very fast, it was a faulty NEW thermostat. It still runs hot, I think I need a new water pump
Assuming it did not overheat before you replaced thermostat and water pump you may have installed the thermostat backwards. It is also possible the cooling system wasn't refilled properly and was air bound.
A lack of water in your cooling system will cause your 2002 Pontiac Sunfire to overheat. A malfunctioning thermostat can also cause it to overheat.
first of all, do you have the right thermostat? ie: winter, summer. if so i would get the radiator checked, it may be getting pluged.
sounds like a stuck closed thermostat. ^I agree. Wife and I used to one and that was a reoccuring issue with it.
Usually the car would run cool, unless the thermostat is stuck partially open.
A stuck or incorrectly installed thermostat.
The radiator fan is not working,or not working properly,or possibly the thermostat is bad.But,usually if the thermostat is bad the engine would still overheat even if you speed up,so I would suggest testing the radiator cooling fans.
If you drive the Dart like I would (like a bat out of hell) the car would most likely overheat from fast acceleration, and more strain on the engine than what is needed. If you drive legaly, it could very well be the thermostat. Be sure that you use the correctly dilluted antifreeze.
the first thing i would look at is the thermostat if its not opening and closing at the right time this will cause your enginr to overheat.
bad water pump or thermostat. check both.
Check the fan thermostat.
If the electric cooling fan(s) are not coming on that may be the problem.
By itself, the thermostat would have to be stuck closed causing a severe overheat condition to cause a loss of power.
U NEED A THERMOSTAT. THAT IS WHAT HOLDS THE COOLANT IN THE RADIATOR, SO IT CAN COOL DOWN BEFORE IT GOES BACK IN THE MOTOR.
Follow the top radiator hose to the engine, what that mounts to is the thermostat housing, remove this and there is your thermostat. * ** *** **** ***** Actually, on my 1997 SL2, the thermostat is on the bottom radiator hose. I would check the "Saturn Thermostat Pictures" link below, which also has installation and removal instructions.
Yes the temperature gauge will still work. If it stuck open the car will run cool. If it is stuck closed the car will overheat.
If the Chevy Celebrity radiator is smaller that the Saturn radiator it might well overheat from not enough cooling capacity. If the Chevy Celebrity radiator is the same size or larger than the Saturn radiator I would think it would not over heat.
If you are unsure if it is heating because of a water pump or a thermstat, you can find out by removing the thermostat. If it still heats without a thermostat, then you know it is the water pump. Without a thermostat, the water flow has nothing to cause it to heat unless the water pump fails to circulate the water. No circulation of the water would cause the over heating.
because the water pump is not working properly....
Bad thermostat, plugged radiator, blown head gasket in order of expense.
Try the rad. fan or the rad. fan relay
