AC problem - what does this reading mean?

And yet others say "don't go messing around with your truck doing stuff you've never done before when you have an 8am delivery the next day".

 

Hey guys a quick question. I just replaced the belts, and I noticed that the tensioner pulley on the accessory belt is... wibbling... is the best I can put it.
See how all the other pulleys are solid, but that one's wonky. And it's spring is also slightly dancing. Does it need adjustment? Or do I now need a whole new tensioner too?

 

Or more likely just leave it alone right now because the dealer is closed and I got to deliver in 8 hours.
These are not adjustable, huh...
Do you think I messed it up by pushing it too hard with the socket wrench hole when I was changing the belts?
And do y'all think I can make my delivery tomorrow, or is it about to go kaput again?

 

Good to know. It's just weird that the fan belt tensioner is rock solid, while the accessory belt tensioner is wibbledy. Maybe it's just getting used to the new belt...
