there is a fan by my radiator that only turns on when the heat is turned on, when the heat is of that fan is off. when ever that fan is on it sounds like the motor in the fan is messed up, it sounds like its screaming. i checked it out and the fan is electric its not hooked to any pully, what is the name of the fan? hard to replace?

 

Make sure your A/C is off and try it again. I am thinking maybe it is the condenser fan. It shouldn't run when your A/C is off, if that is what fan it is. Shouldn't be too hard to replace.....

 

spray sum lubricant in the area where it turns

 

does it run the whole time or jsut at start up?..... or after you just turn your heat on?

 

I hear the noise for a while after i turn the heat on, but after about 20 minutes the noise stops. I can't figure out if there is any one thing that is making this noise happen. Like, it doesn't only do it in the rain, or when it's extremely cold. It might do it one day in the rain, then the next rainy day it might not do it.
I really can't describe the noise. I am going to try to take a video of the noise and see if anyone can help with that.
Thanks alot.

 

Yeah get some lube and lube it first. On my other car same noise but from the pullys and the alternator took some belt dressing from the mechanic shop greased that monkey and it was fine and live happilly ever after

 

Here are some pictures of the fan. In the video you can't really see anything, but you can hear the sound. You can see me turning the heat off, and the sound stops. Then me turning the heat on, and the sound starts again.

Spray silicone or white lithium grease on it.

 

I just bought the white lithium grease. I sprayed it on there tonight and then turned it on. It didn't make the noise. So hopefully it is fixed. I will let you know if it comes back.
Thanks
