reapeated drive belt failures

Never have I seen that happen. Hang around here long enough and you get to see and hear it all.
Damn good thing you found that piece. Getting it back on and locked down tight will definitely solve the initial purpose of this thread.

The second picture is a mysterious part that i found at the bottom of the engine compartment lying on the plastic engine undercover. looks like some part of a pulley, but it doesn't look Yaris specific. I'm sure mechanic left it there by a mistake. does anyone think this belongs to the yaris?

BTW: Happy New Year everyone!

This is crazy glad you can now repair her. That water pump pulley is always going to eat belts and make noise now its in that condition, time to go find a good one at the wreckers to replace it.

make sure you check the water pump and ac bearings for wobble in case those need replacing too as they were taking a beating while the belt wobbled.

thats the nut that holds the pully on..so i assume the pulley just "hasnt fallen off yet"

Mine did the same at about 18 monts old. I found it laying on the bottom cover and screwed it back on the compressor. That lasted about 10 minutes. Took it to the dealer and they replaced the compressor under warranty. I wasn't happy as I thought some Loctite would solve the problem without disturbing the line set of the compressor which could create future problems.
They insisted so I let them do it and have had no problems since. I am convinced it was a manufacturing defect in that no Loctite was applied from the parts factory.

this is all very weird indeed. i guess it must have unscrewed itself?
i'll try to fix it all the next time i see her. thank you all for helping!

here is an update. after i screwed it on, she left the town and reported no problems with the belt. she came back 4000 miles later and the part is laying in the bottom of the engine compartment again. when you screw it in back, the threaded thing in the middle of the AC pulley just rotates freely with no resistance. so, the part cannot be attached securely and it will get unscrewed again by itself. I have no clue how it works and what is broken. see the picture of the AC pulley and the threaded thing in the middle.
Thanks!

Now I suspect it's the AC that is at fault and locks intermittently, tearing the belt. I'll tell my kid to have the compressor looked at. It's probably $$$$.
