Sounds like it is probably still good. Does the fan clutch engage with a roar when you first start the engine (and for the next 20 sec or so)? Does the car temp stay relatively stable when idling? If all of the above are true then your clutch is probably in good shape.

I spun it again with a lot more force this time and I got it 5/6 of a turn...Not quite one full rotation, but close.

Temperature stays OK when idling, but it does not roar at all -- ever not even first start. I thought it was strange when I first got the car because of it, but I thought it was because the cooling system was OK...but now ever since the scary stuck in traffic red line event, I need it to be functional.

My aux fan does not engage either, but I'll tackle that once the VFC is functional.

Just wanted to post the tool which I have been using to lock the fan clutch:
Not sure what the item actually is...but it works!

All I did was bend the tip as shown and it works 100% perfect
