I have a 97 Honda Accord V4, my radiator blow up on me so I replaced it dis weekend. I noticed that my car heats up pretty fast when am parked, red light basically just idling i mean it needle goes all the way up! Seems like the Radiator fan doesn’t come on when am driving, but it does come one when i park. I've check my A/C fan and it runs fine when i turn the AC on. I replace the Thermostat, upper and lower hoses. I checked the Radiator Fan relay but can't see anything wrong with it. Connected all my electrics back up. Does any one know where the auxilary fan switch is? Pictures would be good please. I've done some reading on this and just thought I would post my problem and get some replays cuz am no mechanic but love to work on cars. Any help would be great, thanks.
