Question about 1993 Honda Civic 4 Door
If you are losing fluid and you do not see it on the floor it is going either of two places. In the oil or out the tailpipe. The fluctuations you see and the fan going on and off is the result of low fluid levels. Sometimes the sensors are touching the fluid and sometimes it is not. It sounds like the head gasket is bad. Check the oil filler cap and dipstick for white milky creamy stuff. If you see it the water is going into the oil and is destroying the lubricating properties of the oil and will destroy the motor if not taken care of. Change the oil very often until it is fixed. If there is no milky stuff it is likely leaking to the exhaust which is not as bad but still needs to be fixed. If you pressure test the radiator system it will likely loose pressure slowly if the gasket is bad.
