anyone else have this same noise under thier hood

[Roland69]

I have some wierd noise and I think it might be in the pully system somewhere. I can't seem to pin point it but it's consistant with the RPM's. sound's like a chatter or like timing gears or something like that hard to explain it's like chchit-chchit-chchit.....maby I have a blower and wasn't aware of it Could it be the power steering pump or maby a bad pully or is what I'm hearing normal.

It could be a pulley that is slightly out of alignment with the rest of them. You could remove the belt and run the car for a minute (dont let it overheat or anything) and see if that was the cause.

Then before installing the belt again see if the pulleys all spin easy or if you can hear the noise. A smog pump that has the vanes hitting the wall sounds like that too, as do some PS pumps (like you said).

Good luck.

Oh, if you have a mechanics stethoscope, you can use that to find the source (that's how I find that kind of noise). Be real careful of moving engine parts and all that!

 

[Roland69]

Thanks I never even thought of the smog pump. Do they do this often

 

[brandonshady]

It can definitely be the smog pump... I went through hours of listening, metering, and even taking the serpentine belt completely off (as stated above). Only to find the noise comming from my PS pump. I could always tell the noise was comming from the driver side though.

Good Luck

 

[Roland69]

well now I have a few idea's on what to look for.

 

[postalbunny]

check the a/c clutch... mine is a little loose and will chatter like that. Does it goa way w/ the a/c on? I can hold the clutch (when a/c is off) and teh chatter dissapears.

you can use a rubber hose about the diameter size of your heater core rubber hose about 2-3 feet long and use it as a stethscope to locate the problem just hold one open end to your ear and probe for the sound with the other open end be careful of moving parts and believe me it works and goodluck....

 

[Roland69]

I don't have A/C so I can rule that out....I know the noise he was talking about and it not like that

I have heard some abnormal noises on cars from belts. Not just the normal squeak. Try a simple test, spray some wd on the drive belt and see if the noise goes away.

 

[Roland69]

would the belt tensioner make a noise like this

 

[brandonshady]

it can sometimes cause the belt to make a wierd noise when going out. That spring load gets weak & the belt can begin to move & rub on pulleys. Is it really easy for you to lift it, or still stiff?

 

[Roland69]

I'm pretty sure it's still stiff but I can check it agian

 

[Joey5.0]

Its your Power steering pump.

 

[Roland69]

I thought it might be but Hissin has a good point on the smog pump...Would a new P/S pump be the same or can I just try draining the pump and fill with synthetic ATF

It's a toss-up with reman'd PS pumps - they tend to be noisy right out of the box. A flushing is always nice but I wouldnt hold my breath that it makes things quiet down (if it's the PS pump).

Not much help there........ Good luck.

 

[Roland69]

I can live with the noise but if it's something like a pully about to fly off I get a little worried about that...I might try taking the belt off tomorrow and check things out.

 

[QUIKSVT]

I had the same noise you described, ended up being the water pump of all things.

 

[Roland69]

the water pump is new
