Pushing the car while in gear is how I turn the belt on with the motor turn.

You used the correct belt. The OEM belt, 034 260 849, is described as size
12.5 x 912 La
and if you buy non-OEM you will probably be steered to something like a
CONTITECH 13 x 915. The extra 3 mm may be because the belt is 0.5 mm wider
Either option is tight. I "roll" it on. That is, I put the belt around the
crank pulley and get it
started onto the AC compressor pulley. Then, while holding it in position
with one hand, I turn
the crank pulley with a ratchet on the crank pulley bolt. It rolls right on
with no damage
and, when the belt is tensioned, the adjustment falls about in mid-range.
Roll it off in a
similar manner using some sort of flat bar to force the belt out of the AC
groove as the pulley is rotated.
