ok well this is dumb but i need a quick question

what belt is it thats on the air condition? and what else is powered by that same pulley on a 90 GXL

its the 2 bottom ones and under to the right of the water pump housing....
just wondering which it is.......
i know it's a dumb question and prolly easy but its just a quick question

 

The AC & it's idler pulley is on a belt by itself.

 

so on that same pulley its connected to the AC and the Idling for the AC???
so its ok if this belt is not even on though????

 

As long as you don't want/need AC
