Hi, I have a 95 Civic EX and I just replaced the radiator. I talked about this before but I didn't know what fan turned on from questions asked by other members lol but I know now because it happened again multiple times. For some reason when I start my car on my driveway, on the second click on the ignition, my electronics come on (normal) but so does my radiator fan (???). All of my A/C buttons are off and the heater is off as well. This problem didn't happen again after the first time (couple months ago), but happened again the day I replace the radiator. Does anyone know why it came on and how to prevent it from happening again in the future? Is it because the radiator is new and getting used to the car?

 

I'm not really sure what you are asking. Your radiator fan (passenger side) should only come on at a certain temperature. Your thermo switch could be going out possibly?
