2007 Alternator in a 2012

[Jason@SportsCar]

The pulley changed at some point, but I don't recall if it was with the bodywork in 2012 or if it happened later. I have interchanged the two, just swapped the pulley - it is visibly different, you can't miss it.

Thanks for the info. I will check the pulley.

There are two different length belts available for the 2012. The pulley on the alternator may be the difference.

I don't think it was for an AC delete unless the delete required an idler pulley to replace the AC compressor. Some GM cars have this.

The difference in the belt is about an inch. I always buy both and return the one I don't need.

Thanks for the pics. I really hope I don't have to take the pulley off the 2012. The shaft and nut are a rusted mess.

Can't imagine why they would offer two belts. Don't think you could get a non AC Yaris in the U.S.

The pulley change was a shoulder on the backside of the pulley which pushed it out a few mm. Looking at pics I believe this was later than 2012, like 2015ish.

Hard to see here, but in the lower left corner you can see alt pulley with the wider shoulder:
