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 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
