3.1 engine
The car needs to be up in the air, you will need a good hydraulic jack, safety jack stands and a full set of hand tools with socket U joints and varied extension sizes. Support the oil pan with a jack and a large flat block of wood and release the tension on the "through" bolts of the mounts, then slowly raise the engine off the mounts and unbolt and replace the mounts.

Sorry for the delay. I am personally going back to answer your unanswered question.
I do not know if you still need the answer, but I am going to answer it in case you still do.
Click on the following direct Link. It has the Serpentine Belt Diagrams that you will need for your specific engine size and options (AC/No AC...etc).
To answer your direct question: Yes you have to remove the Engine Mount. Scroll Down and see Diagram #G00286624 on the Link.

Unplug relay at the bottom of antenna to stop the motor. Leave antenna up and keep on driving or replace antenna to watch it go up and down.
SOURCE: replacing motor mount
Put the car on ramps. Using a floor or scissor jack and a block of wood, find aa appropiate safe place to jack up the motor to relieve the tension on the motor mount you wish to replace. Remove the old mount and replace with a new one.

You don't have to remove the mount. Go thru the wheel well on the passenger side and remove the motor mount bolt just right of the crank pulley. Then remove the stud that the nut was on. Then remove the sleeve that the stud goes thru. Then you can change the belt.
