The correct setup of the Holden Commodore VS V6 serpentine belt is as below.
Now some people say that it takes 2 people to change this.
Well they are wrong. Now all you need to do is place the serpentine belt on as pic with the exception of the alternator. Now you will notice it doesnt reach the alternator. Thats fine. Just get your 15mill spanner onto your tensioner and pull down anti clockwise on the bolt and the tensioner will lower. Now once that does you will be able to push your serpentine belt over the alternator and all is done.
Simple really but just thought i would post it as i forgot how to do it and it took me about 20 min to remember. There difficult asswholes to remember actually.
This is for Holden V6 VS commodore only.
(For the yanks out there) This is the Buick engine so you may be familiar with this lolol.
