No. I turned it off and on. told the mechanic too. He said it turns the bearing inside the compressor anyway even if off.

The sound is indeed similar to a video here https://acurazine.com/forums/second-...ulleys-894015/ . I was surprised when he said that.

Removing the belt for me is a major job. But how would that help find out? Because the AC isn't turning anymore, I'd turn it off, but alternator will work for a bit nonetheless? So if sound is still there, it's the alternator, if gone, it's the AC? Am I on the right track?

 

 

had this same issue 2 days ago-power steering fluid was very low-got 2 bottles of fluid from Honda dealership (1 for now, 1 for later), less than $10, problem solved.

 

My steering fluid got topped off about 3 weeks ago.

I am not trusting that mechanic diagnosis that it's the compressor. I'm still inclined towards the alternator. I also have a strong suspicion of the drive belt tensioner. What I had changed was the timing belt tensioner last year, and if its not the same, then that tensioner might be stressed now with a new drive belt that i should've changed its tensioner along with it.

I''ll soon find out and report.


Thanks a lot for your help guys, surely.

 

Today the battery light came on with 'check charging system' in dash.

Should I take this as the whining sound is indeed the alternator? Could it still be something else and this a coincidence?

Is it ok to keep driving a bit till i fix it?

Please help!

 

sounds like an alternator. You should change it asap to prevent a larger bill should it fail on you while driving.

 

Thank you. Here's the video with the sound https://acurazine.com/forums/second-.../#post16182550 . It's been whining since a few weeks. Check charg sys came on today. Hope i'm not too late.

 

I just listened to youe video. it is definitely the alternator going out. i recently replaced mine and it sounded just like that. It isn't too bad to replace. Tight fit but you could do it if you are mechanically inclined.

 

Denso 387USD installed all in. 2 yr warranty.

I'm guessing that's re-manufactured.

 

The guy is saying its brand new not reman. Is that possible?

 

I suppose yours was not the power steering as per previous page but alternator finally.

You were correct, alternator. I changed the drive belt pulley as well. Put in a brand new Denso alt.

Gonna sell the old one to be remanned.

Thanks!

 

What on earth is that?

 

I remember hearing something like that before, turned out it was the failing motor of the cooling fan, is that sound constant when the car is on?

Also I know this sounds dumb, but is it possible for transfer case to be whining at idle? like constant level of whining noise from P to D, does not change with revvs, can not be heard while driving but seems loud inside a garage and also it "looks like" noise from your previous video, but alternator gives smooth sound via the long screwdriver

 

The old wine in previous video of 2 weeks ago was gone with the change of alternator.

this new sound is not constant. Has not happened all day yesterday. albeit, while running in car, you can't really hear it. But it's not constant.

I'm wondering if a poor tightening of the drive belt pulley, which was replaced two weeks ago, could make such a sound. altho, it seems to be coming from the front, the fans area.


when changing the alternator, they needed to re-fill anti freeze. Does change the alternator require an anti-freeze refill in the radiator?

the mechanic heard the video above and can't really tell what it is.

 

This sound has not come back, but im worried its something that may be brewing....

Car drives smooth tho.
