Question: I am trying to put on the air conditioner belt for a 2009 2500 HD Silverado truck and I need some help on how to do it, thank you.
 Answer: OK. What exactly did you need help with?

Question: How to put the tensioner belt on.
 Yes, it can be difficult. Kind of hard to explain. The belt needs to be partially on, then use a ratchet on the tensioner, move it as far as you can, then with your other hand hold the belt so it holds the tensioner so you can reposition the ratchet to gain a little more tensioner movement.
