The coolant level sensor is located on the radiator. If you are looking at the engine from the front of the car it will be on the left side. There will some kind of clip holding it in the radiator. Removed the clip and pull the sensor out. You will lose coolant so try to swap it out quick or drain some of the coolant out. Once new sensor is installed, install clip to keep the sensor in place and reconnect the wires to the sensor. Crank the engine and make sure the coolant level is full. This should correct your problem.

First, what is the problem that you need to replace the actuator? Is the air flow from the vents not changing? If this is the problem, the actuator is inside the venting behind the control panel and is difficult to get to but is possible. Follow the hoses on back of temp controls to the actuator. There should be 2 small bolt screws to remove to change out actuator.
If this is for something else, let me know
