there is a loaner tool from advanced auto that I use and helps out. Just ask them about the FWD serpentine belt remover. I did find mine to be kind of tricky to get the new one on.
If you are doing it by yourself (as in no extra third hand), you may want to use some duct tape to hold the belt in place until you can slip the last portion in. And yes, that $25 tool from AdvanceAuto or Autozone helps greatly.
