[TR] Alternator

[Paul Tegler]

On a GM unit.... the fan CAN spin freely easily.   The fans are not 
physically attached to anything....just compressed behind the pulley and 
a step on the shaft when the nut is tightened.
Some have a key notch, but most are well past the key on the shaft to 
have it stop them from rotating.
The screech must have simply been a loose pulley. nut
