Hey I have a f-150 89 extented cab and I been having problems with the AC, I think it is the pullie that is attached by the belt. Well today I was driving and the whole thing is makeing a funny noise and seems to be lose and comming out. Does anyone have like a diagram of what all thoes pullies do and the way the belt is supost to go, it seemed to have rubbed off under my hood? And does anyone know an someone easy way or a trick to get to that stuff? any info will help

 

What size engine

 

I have a V8 5.4L

 

Its a 98 then not a 89 correct
