Sorry to bring this topic up from the dead. I just installed a bando 7PK1920 belt on my 08 Scion TC (not supercharged) and installed is not completely accurate. I cannot get this belt on for the life of me. I verified and reverified the placement of the belt and I know I have that down 100%. I also was able to fully depress the belt tensioner and I'm about a cm away from sliding the belt on #6 on the diagram. I have tried to slide it around the alternator and no luck either. I have had help also. I do not know what else to do and am extremely frustrated. Took an hour to get the old one off and the new one and 5 hours trying to force the new one on completely. Ridiculous. I have quite a bit of car experience and this isnt my first rodeo.
