Strange little chirping noise

johnnsb · 01-21-2013, 01:11 AM

I just got my 2008 RAV4 Limited about 2 weeks ago. Had a 2000 4Runner for long time before that, and an old-school FJ40 before that.

My question is what's the typical sound I should hear when idling and accelerating. I've noticed this little chirping sound coming from the car when I am idling a little bit when I am accelerating.

I've heard some of these engine sounds before, but I am curious if a 2008 RAV4 with 51k miles on it should sound like this or if there are typical causes that would be investigated?

I've got an extended warranty that seems pretty comprehensive - I guess the question really is, a.) what does this sound sound like, b.) is it normal and typical or something to get checked out, or c.) something to get checked out right away or wait for normal service?

I've included a clip of what it sounds like because that might be the best way of describing it.

thanks!
John

I don't hear anything unusual

I suggest an automotive stethoscope. Your sound does not sound alarming, but you may want to know the source of the sound. http://www.harborfreight.com/mechani...ope-41966.html

It's difficult to tell what the cause is, but the noise sounds like it could be a squeaking belt, although its cyclic occurrence appears to be more frequent than being belt-caused. Hopefully it's not a bearing, as in the alternator.

Thanks...that was definitely one of my thoughts. That little cyclical squeaking or chirping sounded like a few trucks I've heard. But then I realized those trucks were older, so i wanted to check it out.

Yeah, so I listened to some youtube and it could be either, but it sounds a little more the alternator bearing noise. I guess I should probably get it checked sooner than later.

Sounds like a belt, take-up pulley bearing noise to me. This is abnormal.

These guesses sound about right to me as well.
