One of my cooling fans squeaks when I spin it by hand, with engine cold and off of course. 1996 Impala SS. Any thoughts ?
Great information. Yes, one fan squeaks a bit when I spin by hand so I will replace it when I get a chance. Thank you!There was a TSB regarding fan relays. They would overheat causing the relay to melt the base it was plugged into which then = fan fail. GM made a external relay/fuse harness for the primary fan. innovativewiring.com makes a harness with both relays.
OP, pull your fan relays and look....if heat fatigues than do the relay swap mod....and yes fan motors do eventually die so if yours squeaks, binds, wobbles than replace it
That's a neat thing to try. At 40,000 miles I don't think that it's worn out, but if it is I have no problem repairing it. But I do like your idea of giving the electronic cleaner a try. I think that the speak could be due to the fact that I drive the car less than 500 miles per year these days. Thanks for the suggestion.Have had some success in removing the blade/frame from motor,and spaying electro-clean inside. Both with no power applied,and connected to 12v via pigtail. Much dirt/crap came out,and motor became super quiet once again. Obviously this will not repair a totally wore out,or damaged motor,but doesn't cost much to try...
