Would help if I knew the year, but the power steering pump is probably your tension point.
-Remove Air cleaner assembly completely
-Right above the power steering pump fill cap there is a bolt at the top of the bracket loosen it, but don't remove.
-There are 2 bolts on the back of the power steering pump that are in slip channels. Again, loosen but don't remove.
- Then down in under the bottom of the power steering pump there are 2 bolts one is a locking bolt with the head point towards the radiator. Loosen it but don't remove it. Then there is a tension bolt where the head is pointing towards the fender well. Loosen it and your belt will gain/loose tension so it can be removed.
-Then reverse to tighten everything up
* I hate the design. It's to much work to replace the belt in my opinion. I have done it a few times. I belive the size is 13mm or close to it.
