Editing the original post, because it is a silly thing. Took like 5 minutes for a mate and myself....
-You have to remove the top nut on the alternator and loosen the lower one to let it pivot down as much as it can.
-Then you have to remove 2 of the 3 AC bolts. Keep the upper left one. AC can pivot UP on the bolt. 90% of the people I asked told me not to remove AC bolts... wrong.... veryveryvery wrong... anyway..
- place the belt on the AC pulley (inner side) and start feeding the belt to the ALTERNATOR pulley, while rotating the pulleys by hand. Easy, really.. you will see..
- Mate of yours have to watch belt on the AC pulley to make sure it is not moving to the outer part of the pulley (screwdriver, crowbar or whatever, don't need to use force). If not, the belt will just walk to the outside part of the pulley, you don't want that..
And that is it, belt is on.
Now, using a crowbar, force the alternator back in place. Gently, no need to manpower it. Screw the bolt in place, alternator done.
Remember the AC pivoting upwards on a not to happy bolt? There is quite a "pressure" on that bolt now... So grab a floor jack and lift it's ass back in to its place. This one is tricky, because if you lift it "badly", the compressor will move up and OUT. Which is bad. Just find the right spot and tools to lift it back. Bolts in, done.
I'm doing a BIG service on my 159 2.4, including rotors & pads, belts, water pump, intake manifold cleaning, swirl flap delete, new crankshaft pulley, broken exhaust studs..... and whatever it is throwing at me during the process (like... failing engine mounts and leaking steering rack, to name a few) .... there has been a lot already..
But I got stuck with the alternator belt install. I haven't found any tools that would fit our application and I'm not able to stretch the belt enough to fit over the pulley.
Searched Youtube, didn't help.
Searched the forum, tried the "undo the upper bolt on the alt that will pivot it..." yeah, like 2mm.. not helping much. Also undoing AC or alt would just generate a bit more PITA when it comes to bolting it all back together. For other makes I could find tools for this but I can't adopt them.
Some people claimed they found a way to fit the belt, but not mentioning how..
Could someone enlighten me, please? It is quite frustrating...
Thank You in advance
