guys i have a 2001 sunfire my rad fan is not working and my tends to overheat in the warm whether when im not moving, i have checked all fuses and wires and they appear to be good so im guessing the motor is shot, just wondering how much work it is to change this motor out, does the fan need to come out of the car? if fan does have to come out, how hard is this and is it necessary to remove the radiator because a few gasrages told me i have to?
Thanks In Advance For Any Replies
Have you tested the relay for the fan? There is a way to take the relay out and ground one fo the connection (in the fuse block) to make the fan come on (if it is not bad). To replace the fan motor the fan has to come off, it is not too bad to do. The fanmotor is about $35 at GM. You might be able to go to the a junkyard and get one as well. I would test the motor to see if it is bad.

i never tested the relay for the fan, how exactly would i do this, i wish the motor was only 35 GM told me its 159.00 for mine.
If you want to test the fan the quick and easy way, cut the wires and touch them to your battery. It doesn't matter what ground/positive is, it'll just change the direction of the fan in accordance to how you touch them. If the fan still works, splice them back together and keep hunting for the next problem (relay)
is there enough wire there to cut and reach the battery or do i need to join a piece in to test that, also there are only a couple of wires on the fan motor n e idea where they are going

I would not cut the wires on the fan. You can either unplug the fan motor, and take 2 wires and run them to the battery and touch them to the prongs on the fan connection. The wires on the fan motor lead back to the fuse block under the hood. The ECU sends a signal that flios that relay to turn on the fan motor. Later today I can tell you what post on the fuse block you need to ground to make the fan motor turn on (if it is still good).

Unplugging would work, too--but I took a fan out last night and I'm thinking the "clip" to unplug it faces the body of the fan itself. It was a little bit of a PITA to get to while the fan was still hanging in it's place.
so did u take to fan totally out Omega, or did u just let it go and let it drop down a bit,
an easy way to test the relay is take out the fuel pump relay and put it in its place. put your car in the run position (but don't start it, it wont start anyway, there's no fuel pump relay) and turn on your a/c.

Ok here is what you need to do. Take the cooling fan relay out. If you are standing next to your driver side fender looking down at the fuse block there is 4 prongs where the relay fits in. Take a wire with each end stripped. Put one in on the left rear pin and the other on the right rear pin (remember right and left from your view looking down and rear from you). The fan should come on if it does not then it is bad.

thanks john will try that within the next few days once i get a day off work.

I took it totally out--it's the car we're doing a turbo install on and I've taken most of the cooling system out for modification. The fan was too bulky to keep in there with the boost components. I'm sure he'll have us install a high-CFM Perma-Cool in it's place.
how much work was it to get the fan out Omega, did u take it up through or down through and did u have to remove/move the radiator to do this.
The radiator was loosened up but not removed (two bolt on top loosen it.) There's a bolt on the lower belt-side of the fan that holds it in. Once that's out, you pull the fan to the belt side which takes it off two mounts on the other side. I slid it down towards the ground after I unclipped it from the top of the radiator. It has a bracket that kinda "hangs" off the top of the radiator.
thanks omega, at least now i got some clue how to get it out, i sized it up ther other day and it didn't seem like much just was too cold out to tackle it.
