Engine moaning/whining
 

Hi all,

I have notice lately the engine makes a moaning/whining on park or drive but stopped as the RPM goes higher I don't hear the sound. Anyone had this issue as I can't figure out what it could be.

Thank so much.

I'd check your air box and make sure it's fully clipped, and that the filter fits properly.
Or maybe you could video the sound, could be a lot of things. Fan's, A/C compressor etc.

Here is the audio. https://drive.google.com/open?id=1Ll...Olji2iTdReAgZ_

Sound is faint in the link, but sounds like power steering whine. Foaming of the PS fluid in reservoir would be a confirmation.

Usual reason is air pulled into suction Inlet fitting of PS pump. A worn oring on the inlet fitting is fix. See attachment. Numerous posts about this problem on this site and youtube videos.

good luck

I have had an alternator growl or whine due to internal circuit failure. New alternator is fix. Have alternator tested.

good luck

Thanks I searched couple area and it does seem like Alternator might be the problem. When testing if it gets the correct voltage do I just wait until it fails or replace it? like many have tested which past but the noise was there.

I'm going to follow this diy to test the alternator but I dont have any issue with starting just the whine/growling https://acurazine.com/how-tos/a/acur...sappear-424503

Much appracited

Sounds fairly similar to what happened to my alternator a few years back, but I cant find my video. I let mine make that noise for a few weeks then it went out completely. I keep a cig outlet voltage reader plugged in at all times because my alternator has died twice. Should be reading around 14.1V.

I think the bearing on the alternator is going bad as I don't have any charging issue yet. I'm looking for replacement right now.

Looking to replace my alternator as well - it tested fine at the dealer but they confirmed the whine is coming from there, could be beginning to go. What did you end up going with for a replacement? OEM or something else?

My Brother in law has Honda/Acura Auto wracking so I got one from him. If you have Amazon Prime this one seem to have good reviews.
I personally dont like to get a Remanufacture as they tend to fail sooner and no core fee.

Hi all,

Wanted to give an update to this issue. Friday afternoon the noise was louder and I didn't bother to replace it I thought I will just live with the louder sound. Yesterday morning couple stop signs from my house I got the check charging system. Last night I replaced the alternator and no more noise.

I have to say the bottom bolt slot was pain in the neck to get it out. It took me good amount of time to get it out.
