QUESTION: sorry about that its a 2000 s80 t6 twin turbo volvo.

Answer
Chelsea, I will try to explain it as best I can. Crank to compressor then power steering.  Now go under adjuster and back to crank.  In between crank and compressor, pull up to alternator.  Its the best way I can explain it without showing you in person.  I dont have a diagram.  Roger
