What is this whistling sound coming from under the hood?

Hello, I have a 1999 Camaro, and when I start it up in the morning, there seems to be this sound coming from under the hood. It sounds like someone wheeling a wheel barrel around, that kind of screeching/whistling sound.



It cant be the belt, because i just changed the serpentine belt. After I drive around for like 5 minutes it goes away. If i start the car the same day, it doesn't happen again.
What is this whistling sound coming from under the hood?
Does this car have A/C? The reason I ask is because my son had the same issue with his 97 Cutlass. Turned out to be the a/c clutch. The compressor was old and we didn't really use the a/c in NY so it rusted and expanded so the clutch was touching the plate..hence the noise. Your problem (if I understand the noise description) must be along these lines. Check pulleys and your belt tensioner too. Hope this helps

I had the same thing happen on '97 Malibu/GM. Replaced the belt that wore out.Then the sound started in a few weeks. It turned out to be the water pump. Supposed to be a simple repair but took me all day. I got the pump for $32 at O'Riley's..at least saved some money.



It seems that when a belt is replaced, it can put extra stress on the water pump.

yes look at the belt one side is smooth and the one side is riped with lines start with the center hub in the engine then follow the smooth pulleys with the smooth side of the belt and it will be self explanatory .....look around in the engine you should see one (diagram)

Change a car belt?

i have a 1990 dodge dynasty and the serpeantine belt whatever its called is almost ripped and coming off and the motor waste a lot of gas and i mean a lot is it from the belt not being on good? And is it easy to change a serpentine belt?
Change a car belt?
Bullcrap. I just changed the serpentine belt on my S-10 pickup an hour ago and it took all of ten minutes, most of it spent collecting a tool to do the job. The only thing required was a 16mm box wrench to release the tension on the spring loaded idler. If you get confused as to where the belt goes on the pulleys, there is a chart on a tag over the radiator shield that shows how to place the belt on the pulleys.

Your best bet is to have someone do it as you may need a tensioner as well. Putting the belt on properly is critical and best left to the pros.
Um the dynasty isn't to hard to change, if you have the basic tools. As for gas consumption this could be lots of things, the belt could certainly be a contributor by causing valve openings and closings at the wrong times. It could also could cause the engine to labor to generate power.
you can find a diagram of your car and change the belt yoru self and they are only about $30. The gas maybe a time for new plugs and clean the jets
There should be a schematic for the routing of the belt on a placard in the engine compartment. The hardest part is getting your hands down between the motor and fender to thread the belt around all the pulleys. It takes a longer handled wrench than the normal length to get to the tensioner.

As far as the gas usage is concerned, the belt has no fault. You have some other problem there.
IMO, I say try to change it yourself I hate to see people pay someone to do a easy belt change and get charged dubble what it would to do yourself.

Car talk:scrapping noise after belt change?

i took the car to the shop for just a regular oil change+ rotation, dude walks up, sounding grave (note the place was empty...u know, bad economy), said my belts were bad and needed to be changed.. i got serpentine...(http://en.wikipedia.org/wiki/Serpentine_鈥?/a> so they did change, right... so i drive off, get on free way and lo and bhold, at %26gt;60mps my freaking steering starts vibrating.. i got new tires %26lt;4months, and they got balancing already... then after i stopped, car becomes cold, starting off or making bends i got this loud screeching shrill noise from car. any ideas what they did wrong that could have caused it?
Car talk:scrapping noise after belt change?
Bad idler pulley for serpentine belt. Tires need to be re-balanced.


Car talk:scrapping noise after belt change?
that definitely sounds like your power steering pump is acting up. Changing the belt shouldn't have anything to do with it unless it is too loose. Try going out to your car, start the car and leave it in park now turn your wheel all the way to the lock. If you hear a screeching noise then that's what it is. Now you may just need to bleed to system which is done by turning the wheel from lock to lock to lock to lock and so on until the screeching stops. If it doesn't, go back to that shop.

How to change the drive belts on a 2001 Nissan Pathfinder 3.5LV6 DOHC?

Not quite sure where to release the tension to slip off the belts? I have changed serpentine belts before; however, never on this vehicle.
How to change the drive belts on a 2001 Nissan Pathfinder 3.5LV6 DOHC?
alright look at the A/C or Altenator, there should be 2 or 3 screws loosen them up (usually) and that will loosen the belts for you, for more info, send me an email with as much detail as possible.

  • 1997 & 2000 Ford Explorer has a funny sound from under the front end, not the engine compartment. What is it?

    MY son has a 2000 Ford Explorer %26amp; I have a 1997 Ford Explorer (altho mine if 11 years old, only has 80,000 miles) I noticed his car made a funny sound, like wub-wub-wub coming out from under his car and he said it is probably a tire of balancing, or alignment. Well I just bought a 1997 Ford Explorer and low and behold, I have the same funny sound - wub-wub-wub. I took it in for a complete check-up, oil change, serpentine belt, radiator flush, and 4 NEW COOPER TIRES, complete with balancing. I told the garage that the sound was there and he said he could find nothing to pin it on altho I don't think it is as pronounced and before. What could be causing this sound. I drive with my ears as well as my eyes, nose, taste, and feel. Could this sound be caused by that protective cover just beside the wheel - it seems to be a cover to keep mud and debris from getting at the other components of the undercarraige. PULLLeeeezzze - Somebody tell me what is causing the wub-wub-wub sound. Thanks

    It might be a piece of plastic flapping or something. It is probably wind noise. An explorer has the aerodynamic properties of a fridge.

    Remember, keep your hands on the wheel, your feet on the peddles, your eyes on the road ... and don't sniff or lick the tailpipe anymore. People are starting to wonder about you.

    sounds like something is rubbing as you drive.

    Serpentine belt and Drive Belt?

    I got my oil changed today at the Nissan dealership. They told me that my drive belts need to be replaced (they have cracks in them).

    My last oil change (before this one) was at car spa, on the check sheet, it said my serpentine belt was OK. This was back in December 2009.

    I find it odd that after only about 4 months the belts now have cracks in them and need to be replaced immediately.



    This is of course serpentine belt and drive belts are two different things. So are they the same thing? What is the difference?



    I drive a 05 Nissan Sentra.
    Serpentine belt and Drive Belt?
    serpentine belt runs all your accessories like power steering, alternator, water pump and air conditioner, the drive belt is the timing belt and that cannot be seen from outside the engine and there is no way physically possible for a mechanic to see that belt to say it needs replaced without tearing the front of the engine apart, apparently he is going by the mileage on your vehicle and the factory recommended change interval.
    Serpentine belt and Drive Belt?
    On a 4 cylinder engine there is usually only 1 serpentine belt and it's the drive belt (might be different on a sentra). If you live in a place with variable temperature it's likely that a belt would need to be replaced after 5 years. Actually in this case I would trust the dealership more than an independent provider.
    Whoever called them drive belts, do not go back to them. They have drive belts on some motorcycles but there isn't any car that I know of that has a drive belt. If you have a serpentine belt, it runs everything but the cam shaft.

    One more thing. An oil change at a dealership. When you went in for that they knew you didn't know much about cars and that's why they said you need a belt. Never go to the dealership for an oil change, you'll get charged twice as much and they'll try to get you for something else.
    Most cars have 1 belt but some have 2. Some have 1 that goes from crank pulling to the water pump. And another one that drives all the accessories.
    Take a few close-up picture of the belt and post another question. If you see cracks, take pictures of those specifically.



    Then you'll get a yahoo answer on if the dealership was trying to do unnecessary maintenance.



    For the question you asked here, I I think they mean the same thing in Serpentine and Drive belt.
    not all cars have serpentine belts. But given the year I would say yes on serpentine! A serpentine belt Is one belt that runs A/C, Crank, Water pump, Alternator,And on most cars the power steering if the car has more than one belt then you have drive belts and some cars are driven by chain on the power steering that is why some of them are NOT on the serp belt! Hope this helps
