When you switch the A/C on, the A/C compressor engages and puts an extra LOAD on the engine. The engine has to work harder to drive the A/C system. This extra load causes heat inside the engine and the coolant must carry this extra heat away. As the coolant picks up more of the heat, you will see the temp rise. Once you disengage the A/C, the coolant doesn't have this extra heat to carry so the temp goes back to normal operating temp.
There is no such thing as Air Conditioning coolant.
The engine computer uses the coolant temperature sensor and the air conditioning pressure transducer to decide when to operate the radiator fan. The coolant temperature sensor is located near the thermostat housing on top of the engine. The ac transducer is on the line between the compressor and condenser.The engine computer uses the coolant temperature sensor and the air conditioning pressure transducer to decide when to operate the radiator fan.

Fans are activated by the PCM using engine coolant temperature, vehicle speed, and air conditioning high side pressure status to determine coolant fan operation.
It strains any impurities from the coolant.
It is a dual purpose warning light. It will illuminate if the coolant temperature gets too high, and, if air conditioning is fitted, certain faults will cause the warning light to flash. If it is an air conditioning fault then turning the air conditioning off will stop the light from flashing.

It should be above freezing. Normally around 40-42 deg. F
engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty.
The engine coolant temperature sensor is usually on the front of the engine. The coolant temperature sensor will be in the vicinity of the thermostat housing.
Your description sounds like engine coolant to me.
check the thermostat. they often stick and then when the temp goes up it will open and let coolant flow.
To monitor the temperature of the engine coolant.
Coolant temperature sensor is located on the front of the engine. The coolant temperature sensor is a few inches above the thermostat housing.
It tells the computer what the temperature of the engine coolant is...to aid in fuel trim calculations, cold starts, and if the thermostat is working properly. It may also be used by other systems, like heating and air conditioning.
The coolant temperature sensor on a 2001 Jeep Cherokee is located in the intake manifold. It monitors the flow and temperature of coolant through the engine.
Originally this car had R12 refrigerant. It may have since been updated to accept R134a. The coolant/radiator system is not part of the air conditioning system. But the hot antifreeze-coolant is used for the heating system...

Engine Coolant Temperature Circuit High Input The engine coolant temperature (ECT) sensor is a thermistor screwed into a coolant passage in the cylinder head. Sensor resistance is high when coolant temperature is low and resistance drops when coolant temperature increases. The powertrain control module (PCM) provides a 5 volt reference and a ground to the sensor. The PCM monitors voltage drop to determine coolant temperature. If the ECT reads less than freezing temp. when engine has been running for more than a few minutes, the PCM determines a circuit fault and sets this code. Or if the PCM determines the sensor resistance is out of specs, this code is set.
A fan in the engine brings air in then the coolant or the heater cools or heats it then it comes up the pipes and out the vents. You can adjust the temperature with the buttons on the dash board.
