Re: serpentine belt!!
i find the best way to change the belt and the quickest, is to use a 16mm ratchet wrench. i prefer the ratchet wrench because you can precisely position it where you want it, to far down and you'll catch your fingers on the water pump pulley, to high and you don't have enough umf to pull it up enough to slip the belt on or off, with a regular box end wrench it might be positioned completely wrong and be a pita to pull the tensioner up, or catch your fingers.
and with a ratchet and socket i catch my hands on the fan.
