Hey,

I just recently got my radiator fixed after a front-on hit and on idle, the radiator fans arent working, only when a/c is on. Im not saying this is not normal, im just seeing if it sounds normal or not as i never really took notice of the radiator fans before the accident.

Do they work on an on/off cycle? I think i remember on some cruises when i let the car idle down, i hear the fans turning on and off in a cycle rather than constantly on.
Just asking because on my friends S14 and 32R, their rad. fan is connected to some pulley and is always working, but with my car, it seems as if the fans are run by independent motors.

So my question is, when are my radiator fans ment to be working(03 WRX)?


Thanks
-Nick

Yes they work in a cycle. When temp gets to about 94 deg they come on.

Thermo fans (radiator fans) work when the car gets to a certain temp usually just before or once the thermostat is fully opened. And they do work when the a/c is on. to test them start your car and let it idle up to operating temp ( about half way on your temp guage ) then take the idle up to 2000 to 2500 rpm and hold it you should hear the fans start up if not then the temp guage will rise above half way and your thermos aren't working

Alright cool, so it shouldnt be anything i gotta get checked out.
Thought the leaking coolant may have got inside the fan motors or something and put them off but they work on a/c so everything should be all good.

Cheers

Only been driving the car lightly since the radiator got fixed and everything has been perfectly fine. On operating temp idle, the fans arent working, havnt tried bringing the revs up though. Should be fine as the fans work with a/c but ill give it a test tomorro.
