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 properlyWiki User

∙ 11y agoThere are several possibilities.
- The radiator could be partially blocked; this happens when the coolant is not changed appropriately and sludge builds up inside the radiator.
- The water pump could have worn out. If the vanes on the water pump have rusted through, it will not circulate the coolant.
- The head gasket could have failed when the engine overheated because of the bad thermostat. Once a head gasket fails, the engine pushes combustion gas into the coolant jacket, then the coolant is pushed out of the cooling system and the vehicle overheats within a relatively short time.

If the thermostat is changed why would the car still overheat?
it could possibly have either a blown head gasket or intake manifold gaskets leaking
Why would your car overheat if you drove with emergency brake on and thermostat says hot after removing brake and cooling down?
thermostat is more than likely stuck shut from the overheat. Have to be changed.
Changed thermostat flushed radiator new water pump still getting hot and leaking radaitor is not getting hot could it still be thermostat?
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
What would cause your 2002 Saturn sl1 to overheat when idling and the water to boil out of the cap on the overflow tank even after a new radiator water pump and thermostat were installed?
sounds like a stuck closed thermostat. ^I agree. Wife and I used to one and that was a reoccuring issue with it.
Why after I replaced the thermostat on my 1993 Toyota truck 4 cylinder does it still overheat and get hot?
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.
Why would a van overheat after changing the thermostat and 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.
What would cause a 240 ford motor to overheat?
A stuck or incorrectly installed thermostat.
Can a car overheat with a stuck open thermostat?
Usually the car would run cool, unless the thermostat is stuck partially open.
What would cause a 63 dodge dart to overheat when a themostat is installed?
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.
Why would a 1996 dodge grand caravan overheat if sitting in traffic with ac running but cool off when you turn it off or start driving faster?
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.
Your car has all of the proper amounts of fluid no leaks why is it still overheating?
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.
What would cause your 2002 Saturn sl1 to overheat while idling and water to boil out of cap on overflow tank even after radiator water pump and thermostat were replaced?
If the electric cooling fan(s) are not coming on that may be the problem.
