All is fine, no play, no odd noises with exception of a/c tensioner pulley-blah i#x27;ll get around to it. However, the idler pulley is difficult to spin by hand. It looks new, but if you spin it by hand it stops spinning as soon as you stop turning. Like I said, no play what-so-ever, and no odd noises, just stiff would be the best way to describe. They turn with little effort, but wilol not spin freely. When exercised either by yanking the fan back and forth by hand for awhile, or starting the cold engine and allowing to idle a few minutes, they will freewheel as if spinning loosely on a shaft.

Fan Clutch Resistance - IH8MUD Forum.
Feb 8, 2008. #1. My fan clutch is pretty much equally stiff all the time time. By stiff, I mean you can turn it by hand, but you can#x27;t spin it, in any direction, for more than 1/10 of a turn or so. Very viscous. It#x27;s like this when cold, it#x27;s like this after the engine has run a few minutes, and it#x27;s like this when hot. If there is no clutch, the fan would be difficult to turn because you would have to turn the fan and the pulley, which are turned by a belt. If the fan is turning freely with no clutch, then there is a problem with either the belt being loose or the pulley will need adjustments. A fan clutch will look like part # D22175, just as an example.
