DIY A/C Belt Changed

Found out there are some wuuwu or jiii jiiii noises when i switch on the AC during summer, and i think is time to change to belt?   LOL

Took you 5 mins to do the job, just released the tensioner (red arrow) with a spanner to free up the belt, and simply put the belt back. and then you are Done!    

 

Here is the better pic i found on Google, you can see a clear diagram, how the tensioner and the belt work. if you still don't understand it, bring it to a garage and let them do it for you.

 

Here is how the old belt looks like

Put all the things back. and you are done!
