On ur car u use a rachet or breaker bar to release the belt the easiest way to replace the belt is to remove the air box and upper mount if u remove the mount get a piece a wood put that in between a floor jack and the oil pan to support the engine and jack it up when the engine mount is out. Or u can try to do it without taking the mount out let me know how it goes.

Just did this and it is quite easy to do. Remove the entire air cleaner box starting with the top cover snaps. Loosen the large air intake tube clamp but leave the adjacent smaller hose clamp attached. Remove the top cover, separating it from the larger intake hose, swing top cover over headlight and let it rest. Remove air cleaner filter, then remove lower part of air box using 10mm socket for rear mount and gently plying the lower front rubber grommet through its mounting hole. Tilt edge of box closest to engine up to remove. Before final removal use a flat screwdriver to open the lower front wire clamp and release the wire loom that is attached just above the front grommet. Now is a good time to hose off the lower box and clean out all the dirt that has accumulated inside it.

Note the routing of the belt. Now take a standard 3/8" ratchet and insert into the tensioner pulley which is just behind the engine mount. It is not necessary to remove the engine mount and not necessary to remove the tire or splash shields. Pull up on the ratchet with left hand to release the tensioner while the right hand removes the belt from around the alternator. Release the tensioner then finish removing the belt. Installation is the opposite- first route the belt around the crankshaft pulley, around the a/c compressor, and under the tensioner. Pull up on the belt near the alternator pulley with the right hand while the left hand ratchets the tensioner up then slip the belt over the alternator pulley and center it under the tensioner before releasing ratchet. Reassemble the air box. Total time to change is about 15-20 min.
