Cooling Fan Removal

[HUMMERcustoms.com/TAZ]

Be sure you are loosening in opposite rotation. On my 99 Silverado I had a stuck fan. I got a large chisel with large hammer so I could get a very clean start on the edge of nut. You do not want to crush nut threads onto the pulley threads. So finese is much more important than brawn. Once you have nut off be sure to lube well if you ever need to put mechanical fan back on. I carry my mechanical as you never know when electrical problems can arise. I have reused my mechanical on the Silverado before.

Oh also you can use some heat on fan nut just do not heat so much you swell the pulley threads creatin a tighter fit.

Don't waste your time, I replaced my fan with dual electric fans and there was no fuel savings plus the truck over heated once and once was enough for me, cant pull a trailer with the truck over heating.
Cheers
Good luck hope it works.

I have helped many make the change to electric as I have and never heard a complaint. I and others I helped used the 2500 HD truck series GM fans and not other aftermarket brands. Do not know if that could be an issue.

I made my change for HP/torque increase plus just cooled allot better with supercharger and other add ons.

It may not work for all but, just never heard any complaints with factory dual electric. I recommend it but, you for sure need to be sure it is what you need or want as it is not cheap to do.
