High pitch sound (belt?)

drvai · 11-08-2012, 07:37 PM

When starting the car (cold), you can hear a high pitch sounds. Sounds like the belt. This happened last winter also, but the dealer said they couln't detect it. Anyone has this problem?

I did, come to find out it was my alternator.

Any more details? Alternator failed?

I have the same thing. I'm going to take the car Ito the dealer soo. I seem to remember something about idler pulleys having issues. I just hit 60k.

The thing is that's tough to reproduce it when the car is warm

I have a high pitch sound too, sounds like something associate to electronics, and the sound goes up as the rev goes up, driving me nuts

Seems pulley or belt.

It's actually low steering fluid. Sounds odd but it was exactly what mine was. All fixed now
