Below is for the 2.2 and 2.4L engines. Use appropriate diagram:

Fig. 3: The belt tensioner is released by rotating the tensioner pulley bolt in a CLOCKWISE direction-2.2L engine
Directions for replacing belt:
Rotate the drive belt tensioner to relieve the belt tension. The procedure is as follows:
On the 2.2L engine, use aXXXXXtool or a special belt removal tool to rotate the tensioner clockwise.
On the 2.3L and 2.4L engines, use a 13mm drive tool or a special belt removal tool to rotate the tensioner clockwise.
While holding the tensioner back, remove the belt from around one pulley.
Remove the belt from around the remaining pulleys.
Position the belt around the pulleye in the proper routing with the exception of one pulley. It is easiest to keep the belt off of the easiest pulley to access. Hold the belt tight with your hands and using the proper tool for your engine, rotate the tensioner clockwise and place the belt around the final pulley.
Release the tensioner slowly until it site firmly against the belt.
If the tensioner doee not touch the belt or the wear indicator marks are not within specification, the belt is routed incorrectly or the wrong belt has been installed.
