I'm having an issue with my engine overheating and am replacing the thermostat and sensor. I've located the thermostat but where is and how do you replace a coolant temperature sensor?

There is a sensor right by the thermostat. But there may be 2 1 for the computer and the other for the fan. I't s a simple disconnect the wiring harness and unscrew it and put another in.
