My car is overheating. I changed the thermostat and is still overheating. I'm thinking it might be the cooling fan. I'm not sure when the cooling fan is suppose to turn on but as I got off the freeway I pulled over to a gas station and saw that the fan was not on.

Do you
have the same problem?

When does the overheating occurs and under any specific conditions?
Do you have coolant losses issues?

It happens when I'm doing long drives on the freeway. When the car b is under more stress I guess. By coolant you mean water right? Sorry I'm not to experienced.

If overheating occurs only when driving at high speed, that means inefficient cooling and the most likely cause would be restricted radiator.

Yes, coolant is the fluid used in cooling systems. Did you check the radiator level?

When I got home I took off the radiator cap and filled it up with water but it filled uo with just a few ounces.
