Question about 2001 Oldsmobile Alero

Clanking noise when in park, louder with ac turned on

Hello All,
I have a 2001 Alero, 2.4, auto, 102,000 miles. This has been going on for a long time, it has just been ignored. When I am in park, there is a clanking noise coming from the engine bay. I cannot pin down where hte noise is coming from. When you turn on the ac it is noticeably louder. I do not notice it in Drive, Nuetral, or Reverse. I do notice that the noise is much louder and makes the car vibrate a little when in park on a slight incline. When you put it in reverse you here a clank and the noise quiets down. I do not get the when I am parked nose down on the incline. I say it has something to do with the transmission, but this may be 2 different problems. Thanks for any and all of your input.

    Sorry I don't have a Solution to this problem but I had/have a 2001 Alero also and also heard the same "Clanging" Noise.... then about a week ago i was on my way to work , drove the car about 2 miles and lost most but not all my power.... Had the transmission fluid checked and the level was fine..... Almost 100% it's the transmission getting ready to go out.. Although a very nice care I am purchasing the Alero through a Buy Here Pay Here car lot and considering on letting them just have it back... Alero's are not worth the trouble....

Pull the engine accessory drive belt off and check the pulley bearing and the nose of the water pump and AC compressor for play, this may be the AC compressor pulley bearing or the water pump pulley bearing

My car is making a loud clanking noise when driving it's louder than in park

Year make and model helps. But if it does it in park and driving. Most likely the engine is shot. Could be the transmission, because some parts move in it when in park. Find out exactly the noise is coming from.

Clanking noise coming from Allison Transmission on a 2001 Chrevrolet Silverado 8.1 Liter engine

this does sound like theres a loose line tapping the engine/frame,during warm up the engine idles faster which could make it vibrate faster causing the the clanking or tapping noise,if this has started after trans fluid change,then check the lines running from the trani to radiator sometimes the service person might bang into something causing plastic clips that hold the lines to break,try getting under it and have someone start the truck and listen to see where it's coming from also hold the lines & see if the noise stops,the service guy could have unbolted something & never put the bolt back causing the clank ex.line may have a clip holding it thats bolted to the trani pan ?good luck

I have a 2001 Nissan Sentra and 2 months ago I found a bolt that came from a spot which seems to be close to the AC compressor (I assume that it keeps the compressor still), and after that every time I...

Sounds like the belt is just too loose or the belt might be wore out. when it slips it squeals. when you turn on your A/C it slips alot more making it squeal louder. Hope this helps...

Alero loud humming/roaring sound coming from front end.

That's indicative of a wheel bearing, which is why you were told to change that out. However, it's also possible that the carrier bearings in the differential (where the drive axles attach) have gone bad. That happened to me on my 300ZX several years ago, and I had to replace the diff bearings. I would have them checked out somewhere other than a dealer (you'll probably get a better price from an independent shop).

As a sidenote, to be sure it wasn't a wheel bearing, if you hear it quiet down in a turn one way but get louder in a turn the opposite way, it's likely the wheel bearing. If you turn left at speed and it gets louder, then it's the right bearing (since you're loading up that side of the car). If it gets quieter in a right turn, it's the right side (you're unloading that side of the car and not putting as much weight on it, so it doesn't drag as badly). See if you get that symptom just to be sure that the wrong side front wheel bearing wasn't changed.
