It's been a while since I did mine, but I recall that the 12 mm stubby ratcheting wrench paid for itself for taking off the alternator belts. I didn't remove anything else, such as the battery box or go through the apron in the wheel well like others have stated here. The tensioner for the alternator is at the front of the slide, parallel with the grill. The belts then slip over the fan one blade at a time. Pretty apparent once you get in there.
For the ac belt, I removed the splash pan under the rad first. The tensioner is in the middle of the pulley itself. For me, this was not immediately obvious, and cost me some WTF time. This bolt was frozen, I used some Never-seez on re-assembly. Took me about 45 minutes, IIRC. HTH, Greg.
Thanks guys, I got mine done in about 90 mins. I really took my time, not wanting to break any bolts/nutserts (stealership is closed today)I remembered the comment about removing the batt tray. I just started removing what looked logical (batt tray, splash guard pan underneath, and the steering stablizer bracket to drop the SS down on that side.. I didnt have the VC, or I would have done that too. The belts were looking really scruffy. I gave both tensioners a good shot of PB Blaster to loosen them up, and loosened the pulley bolt on the AC tensioner to allow it to move. I didnt have the 12mm ratchet wrench, but was able to use a 1/4 inch ratchet/socket combo. Air tools really make buttoning up go quickly (didnt really use them taking everything off to minimize breakage). Definately much better than doing them on the side of the road. The AC belt looks like it had been replaced once before(so I'll keep that one as a spare), but the two alternator belts were scary looking.
Next baselining/PM steps: PHH/ top/bottom rad hoses, and coolant flush, and fuel filter. I've already done the starter contacts, but I'll still drop the starter for easier access.
