you're right it was...

i went to some mech shop yesterday and the guy pointed out to me how difficult the fan was to turn by hand and was charging around $120 to replace it.

i went home and vacuumed the fan clutch area while tapping the area with a tool to shake some more dust off and a lot of it came out.
got some PB Blaster and just kept spraying it in the center area of the fan clutch, though the opening was tiny and i kept rotating the fan left and right trying to free it up.

eventually it became smooth as butter. i started up the car and sure enough, the fan finally didnt stay on loud-mode, and revved up to 3K+ and no squeak!
however, i drove the car last night and just after i got off the fwy, it seems the bearings might have locked up again and the fan turned on again and the belt squeak noise came back.

i got some "white lithium grease" spray from autozone and sprayed that stuff in last night and once again got the fan to spin very smoothly. drove the car again and So far, still spinning smoothly.

i do have a bunch of freeplay in the fan clutch though.. i'm sure it's going to need replacing, but at least i have a temporary fix.


So about that belt noise.. im thinking that maybe since the fan was being forced to stay on, after the fan got to it's max speed, as the engine speed continued rising (around 3K RPM is where the screeching sound came in), maybe the fan was forcing some belts to spin slower than the engine and therefore caused them to slip??

thanks a lot for all your suggestions
