Whinning Whirring noise After Water Crossings

[akarilo]

Sounds like a low power steering pump kind of, but it doesn't change when given any steering input. Thought it might have been the transfer case, but later realised the noise is present in park, neutral, or while driving. Pitch matches throttle input. I'm thinking a belt driven accessory of some sort, or even the fan cluth crossed my mind. Everything seems to operate properly. Anybody experienced a similar symptom?

just wonder if can be something so simple like slippery wet belt ?

Yep, quiet before, noisey after it's most likely muck ot on the belts. Will go away eventually but may want to hose them off avoiding spraying the alternator best you can.

Sounds more whiney and mechanical than belts. Its been a week since the water crossings.

Ah okay, I actually had the same thing, 99% chance it's the A/C idler bearing. sounds like a PS whine so I searched on here, $3 later whine is gone. Just replace the bearing not the whole idler.

Interesting. I'll try and focus on that and see if it's the culprit. Will it make the same noise regardless if the compressor is engaged or not?

You could remove the belts and see if the whine goes away.

Or remove the AC idler bearing just to see if it goes away

 

[Stevesnj]

Or just the the idler and belt

removing the complete idler it's one job .. you can do is and check .. know few guys running without it and no problems .

Took the a/c belt off and the noise went away . Went ahead and ordered the bearing. Will update with results.

Thank you very much. Followed the link, bought the bearing, installed, whine gone.
