Toyota Yaris squeal

Asked by lauracut113 Jan 29, 2018 at 05:28 AM about the 2010 Toyota Yaris Hatchback

Question type: Maintenance & Repair

My 2010 Toyota Yaris has been squealing upon starting it
up for about 15 seconds and it’s even worse when the
aircon is on. I have had the belt changed (a genuine
Toyota one) and the water pump also. I find when I turn it
on slowly the squeal is less but it is still there. Has anyone
had this problem? It’s just so annoying and so loud and
shouldn’t be happening, it is regularly serviced.

My Dad who is a heavy diesel mechanic, he has tightened the previous one it had on, but he doesn’t want to tighten this one too much caus eit can be bad for it?

Check this out... try turning the key to "on" and wait a few seconds (or more) before starting. I discovered after combing the internet, that there is a glitch in the computer that makes the alternator demand full load if you don't wait a bit before starting. Was not a mechanical issue at all... go figure.

Its the alternator. When you turn car on at first battery needs charging so alternator is under stress. Berring going in alternator. Squeel stops when bat charged and alternator done working

Mine does this and the mechanic said it's the clutch on my ac compressor. Could also be the bearing. I replaced the belt twice thinking that was the problem.
