Radiator fan question

Hey guys,

So my car's been overheating a little. When i'm idling, the car will just get warmer and warmer. Once I start driving the car cools down quickly. The drivers side fan seems to be working great. However, the passenger fan seemed to be slow. So i pulled the passenger side and replaced it with another spare I had laying around. Started the car up, turned the a/c on and both fans were blowing hard. So i thought the problem was fixed. Fast forward a couple days, now the car is starting to over heat again. I then found this out... I switch relay 2 with relay 3. The passenger fan will work when idling but it seems weak. I then will turn the a/c on. The passenger side fan shuts off. Then I'll turn off the a/c, and the fan will turn on, but it won't be blowing as much air as the driver's side. The coolant temp while doing this was at 206. I then drove home and it did fine since traffic was minimal. When I got home, i parked it and let it idle. It went up to 215, and the passenger side would be going slower than the drivers side. The car has an overkill PCM that I got from ithurtz. He claims its for a 185 T stat and thats whats in my car.


Thanks
 


If it's not actually overheating, then I don't think there's actually an issue. Your temperatures will always be cooler while moving than when stopped. When you're moving you'll hover right around your T-stat temp, but while stopped your fans won't kick on until maybe 20 degrees or more above your t-stat temp. If they came on at say 185, they'd be cycling constantly.
