Engine Cooling problem
1997 Chevy Cavalier 4 cyl Front Wheel Drive Manual

I am having problems with the tempature gauge it is on hot all the time. I spoke to some one about this they said it maybe the cooling tempature sensor. My questions is where do I find the cooling tempature sensor? Thanks

Does the radiator fan run? Any applicable trouble codes? In the diagram, the cts is the circle with the D. close to coolant outlet.

If you have good voltage and ground at the fan connector and the fan doesn't run, suspect the fan.

How do I check to see if the fan is no good. Would you still suggest still changing the cooling tempature sensor. How do I change the tempature sensor is it just some thing that plugs in?

Usually if you turn on the ac, the fan will run. You can take electrical connector loose from fan, use jumper wires on the part that goes to the fan. The jumpers connect to battery positive and negative, use inline fuse. If the fan doesn't run, replace the fan. You have to be careful not to get anything caught in the fan, you don't need the car-key to use jumpers.

I can't be positive that the coolant temp sensor is the problem? As far as removing the sensor, you can go to any autostore, ask to see a coolant temp sensor for your vehicle, they will ask for year--make--model, maybe engine size also. Then, tell them you want a socket that will fit the sensor, a socket is no good without a rachet. You need a good set of tools, to work on your own vehicle.
