I am just trying to see if the radiator fans work. When does it ALWAYS go on?

 

hook a jumper wire across the colant temp sensor with the ignition on. that should do it. or hook the fan plug to a 12v source

 

I meant without doing anything exraordinary.

 

let the car idle. when it hits halfway(norm. temp), start watching, let it keep idleing, if the temp goes past that and the fans still dont come on, something is wrong...also shut down the car at this point, dont want to run it hot.

 

Damn, guys, all he has to do is turn on the AC.

 

does it matter if the ac is hot or cold?

 

ac is only cold.

that will only tell him if his a/c fan is working...it wont tell him if his temp. switch is working...i mean do you want to drive around in jan. w/ac on so the car dont overheat.

yea just let the car idle with the hood closed and listen for the fan to turn on. If it starts overheating and the fan doesnt turn on, then its no good.

he just wants to see IF the fans work, by turning on the a/c, both fans automatically turn on vs. if the car overheats, just the radiator fan will turn on, all ya gotta do is turn the car on, then turn the ac on, if both fans turn on then yay, if one or no fans turn on then something is wrong

Yes, but as stated before this will not tell you if the TE sensor is bad. Both fans will come on regardless of the TE sensor if you flick the a/c on. If the TE sensor is bad, the radiator fan will not kick on and he risks the chance of overheating while driving. Sure you could flick the A/C on but why take the chance of overheating when you can simply turn your car on and let it warm to normal temp?

 

So how long does the car need to idle if it is already warmed up to turn on the fan. It is about 2 degrees outside. Should this matter?

took me about 20 - 30 min from a cold start for the fan to kick on. it was probably around 30 degrees out at the time

 

SO if I havent see it turn on lately with 0 degree temperatures, I shouldnt be worried, right? The car really doesnt idle that much. It usually consists of just drving. Dont really beat on the car?

 

go drive the **** out of it, when you get back see if the fan is on

 

my fans don't turn on and my car is running hot under the hood! My temp gauge is still under half way mark.. what can I look at to start troublshooting my fans now...?

 

check your fuses..

 

drivers side is the a/c fan...and passenger side is radiator fan.

 

should the ac fan always be on when the ac is on? Does that include heater/ac?

 

The fan turns on when engine decels while driveing..
