It's there on the passenger side about half way down from the top.  It's hard to see because of the fan blade shroud and the belts.  It's a tight fit and tough to get to.  Put a long ½" breakover bar in the square hole and apply pressure to loosen tension on the belt.  An assistant makes the job easier.
