Accessory belt starting to "slit" horitzontally........

[Lafiro]

I will do that in the morning. Thanks.

But no one has been able to help me solve a year old problem thats getting worse.

Maybe it is the belt? At lower rpm's and with the car in drive, I hear sqeaking. Especially worse when I put the car in reverse going into my driveway, or pulling into a drive through. It applifies with the steering wheel being turned, but like I said only with the car in drive or reverse, once the car is warmed up/just coming to a stop after running for a bit.

Toyota can't "duplicate" the sound, I just say they are lazy, and no one here has had this issue supposedly, so I am out in the cold :(

I really hope tensioning the belt tomorrow really helps with this, and that it isnt something worse, because I couldn't understand what else could be sqeaking like that in the car(engine bay).

The attached files are pretty much what it does, you can tell when I switch from neutral to a gear, the engine gets louder, and you can hear that annoying noise.

They really sound like belt squeal to me.

Lafiro this is EXACTLY the same issue that has been happening to me as well. The dealership said the same, they 'can't duplicate' the issue. Buggers. I've tried tensioning the belt a few times but the noise seems to come back after a few weeks (maybe it just keeps coming loose? No idea).

Anyways, I've learned to live with it, but I am going to try the Goodyear belt to see if that fixes it. I found a place nearby that sells them for $19.99 so I will pick one up maybe tonight and see.

In the TSB's there was one for 07's which updated the tension spec for the belt:

"Some 2007 model year Yaris vehicles may exhibit a squealing noise coming from the engine compartment during vehicle operation. The generator drive belt tension specification has been updated to correct this condition. Please use the following repair procedure to address customer concerns"
