Why do my car continue to run hot?

What is your question?

I have had the radiator, thermostat, all of the relays and the temperature sensor changed. My car is still running hot. When the mechanic let the car run to see if it will run hot and to see if the fan will turn on, the fan does not. The fan only comes on when I turn on the air condition or the heater. What else can be causing my car to constantly run hot?

Sounds like you have found the problem. If the radiator fan is not coming on then you'll need to diagnose the control circuit.

The fan should come on by itself - on and off repeatedly even when the air condtioning is off. There is a temp sensor that triggers a relay to supply power to the fans. Something is wrong with one of those (the sensor or the relay). You could also have a blown fuse. Turning on the air conditioner triggers the fan to come on regardless of whether the temp sensor is working.
