Jesus man, you are making this waaaaaaaaaay harder than it needs to be. You do NOT need to remove anything to take the serpentine belt off. Just put a T60 on the tensioner, bend it to the right to relieve the pressure, and take the belt off of that pulley. Then you can take it off of all the rest of them WITHOUT removing anything else. Why put yourself through all of that???

Brian Bailey says:

Thanks. Was replacing my belt today (put the new one on) and my tentioner's torx snapped at the slot. This is helpful.

Spencer says:

you're supposed to replace the rubber o-rings every time you remove those oil cooler lines. I wouldn't recommend removing the oil cooler lines to replace serpentine belts.

ANYONE WATCHING THIS NOW IN 2020 IF YOU’RE HAVING ISSUES GETTING BELT ON AND IT FEELS LIKE IT JUST BARELY WONT GO ON, STOP TRYING TO PULL IT ONTO THE ALTERNATOR AND RATHER PUT IT ON THE ALTERNATOR AND THEN TRY TO SQUEEZE IT INTO THE PULLEY RIGHT BELOW AND TO THE LEFT WHILE TURNING THE T60 TENSIONER CLOCKWISE.
I’m sorry for the caps but I spent like 2 hours and I was so close to getting it on the alternator but never worked. And even if it had the pin in it I still had no slack. I used the technical way of putting it on. N54 technical diagram, putting it on the oem way can have it rub against the subframe etc…

Eric Pratt says:

Much needed tips. Thank you. Seems all the other videos are for the N52. Was having issues with that black plastic tube in front of the pullies and you're tips helped

omar silva says:
