The belt routing,
1 belt
2 tensioner
3 top idler
4 side idler Left
5 side idler right lower
6 side idler right upper
Lowest pulley on left Alt
Pulley under #4 idler WP
Biggest pulley center Crank
Biggest pulley right AC Compressor
I found it easiest to feed the blet over the AC and idler 5, then around the crank and tensioner, then over the water pump and alt, ending up at #3 idler. Rotate the tensioner and pop the belt on. You just saved $250 not letting the dealer do this.
