i have a belt that needs to be changed. its the one that turn my power steering and radiator fan. all i need to do is drop the power steering down a little and slip it off and slip the new one on and tighten up the power steering right?

 

should be it. remember to tighten it to the correct tension. a cheap trick is to use whiteout to mark it where its already at, that way you know where to tighten back to

 

While you are there you might want to change the alternator belt too, it's probably the same age.

 

Here ya go
