Is the aux belt same as the alternator belt?

[LegoHead]

Do they all run off the same one?

As I thought there were only two major belts cambelt and aux.

my mark 1 rt had separate alternator and power steering belts, driven off a pulley attached to the crankshaft pulley for the cambelt. Problems there led to me bending my valves!

Sadly, I don't have a 172 so don't know if its the same.

Anyone know please?

I am having the alternator belt changed along with the tensioner and alternator under warranty, if its the same as the aux belt then its a cheap 36k service for me.

Yep there two belts on the car one is the cambelt which only drives the cams and is under a cover.
The other os the AUX belt powers all the rest of the things alternator PAS pump aircon coolent pump. Only thing which isn't on a belt is the starter.
