Just an update that the whole job is done....everything is great now. Old belt was slightly stretched/longer than the new. Tension on it seems better as well (from just pressing on it). The engine was starting to surge randomly(usually once you kicked the AC compressor on), and that has gone away...I assume the tensioner was going out. Spent about $200 max total on everything, and am very happy, easy job overall just ended up fighting a few things so used up a whole day and then some...
