How to Remove Coolant Fan!

06-13-2012, 05:11 PM
My alternator went bad, and I got to remove the Coolant Fan in order to remove the Alternator. I did research on how to remove it and can not find a DIY or anything on how to remove it. I got all the screws and caps off already btw.

Do you guys have a DIY or Pics on how to take the Fan out?? Reply asap. thanks!!

Also, in the first few pictures here ( you can see my homemade water pump pulley tool (it just fits over the bolts on the water pump pulley). You can also buy /rent prettier ones with less rust, but that takes all the fun out of it. You'll also need a 32mm wrench if i recall correctly. As noted in the pictures, the water pump pulley / fan nut is reverse-threaded, so righty=loosey, lefty=tighty. Hold your water pump pulley tool stable, put your 32mm wrench on the nut, find a pipe or another wrench to use to extend the reach of your 32mm wrench, and give it a good solid hit. I usually ended up hitting the wrench shown with a hammer to break the nut loose. Next time I get my old car over for some work I'll make a video.

If yours has the electric fan, not the water pump-driven mechanical one, ignore the above. Good luck!
