Chevrolet - Malibu :: 2000 - Whistling Sound From Under The Hood?
Aug 11, 2014
The whistling sound is fairly straightforward but there are little details that are weird.
I noticed maybe 1 or 2 weeks ago that the car would make a whistling sound, not a high pitched one but a fairly middle-high sort of tone. It would make this sound when I put the car and drive and maybe just start to gas it but NOT all of the time. By the time I am at a regular speed it has gone.
But sometimes when I slow down the sound will return and go away when the car has come to a complete stop. But this is not a constant pattern. It is on and off. Only recently could I say it has become more frequent but even then I hesitate.
Also the sound seems to definitely be coming from under the hood possibly from the back of the car but I think front may be more likely.
I read briefly on a few car/car repair forums that it could be anything from an AC compressor going out, a vacuum leak, fan belt, bad water pump, among others. I tried turning the AC on, which I have kept off for pretty much the entirety of the Summer and I heard the sound only once when I resumed driving. BUT, when I revved, the engine seemed noticeably louder; almost like it was laboring though the car drove just fine.
One other thing. Before it sounded as if the origin of the whistle was coming from the passenger side of the car. Just as of today it sounded as though it originated from the driver's side. So I'm really confused now. The car seems to drive just fine and the engine the day before sounded good if not great. I'm hoping it is nothing related to the engine.
*Few Notes:The oil was changed in June. The tires were replaced recently. Though the sound started before this. I was however driving on a really bad passenger side tire for a while.There is a short on the panel that contains the left turn signal. The bad bulb was changed and I plan to find a new panel as soon as Monday.

I recently replaced the fuel pump and afterward started noticing a buzzing/whining sound coming from under the hood. The noise goes away when I remove the vacuum line from the fuel pressure regulator and after the car has been driven for 1/2 to 1 hour. Sometimes it comes back, sometime not, but it always is there at a cold start. Had the shop take a look and they said the fuel pump is ok and recommended replacing the fuel pressure regulator. I did but that but it did not solve it. I suppose I should check the fuel pressure. 2000 Silverado 5.3L ...

I have recently noticed that there is a loud, high-pitched whistling sound coming from under my hood that has progressively gotten worse over the weeks. At first, it would only occur when I had my AC or heat on and would stop immediately once i turned the AC/heat off, and will also happen from time to time when I accelerate. Now, this noise is happening right when I start my car and takes a few seconds to stop.

I have a 2000 Chevy Malibu LS 3.1 V6, the car is burning oil, and I want to know your opinion.
The car had thermostat problems and was overheated, after I changed the thermostat the engine started smoking and every body told me it was the head gaskets, but the car is not burning coolant, is actually burning oil.
When I start the car, first is the steam coming up from the tail pipe, then when the car is warm, the oil smoke stars to come out from the tail pipe.
I checked the spark plugs and all six showed a lot of oil on them, so my question is, is this because the piston rings or the engine is getting oil from somwhere else beside the piston rings. There is times when is not smoke at all, and then again a lot of smoke.
In the past I saw cars burning oil from probably one or two piston chambers, but no from all of them at the same time, and on this one when I checked, all the spark plugs were wet in oil.
I was researching about this particular engine, and looks like have some issues with the head gaskets due to overheating and the fact of the heads being made from aluminum. What can I check before taking the engine apart.

My 2003 chevy malibu suddenly started making a terrible knocking sound, like the sound a can of spray paint makes when you shake it- only much louder. A couple of weeks the oil light went on very briefly when i used the brakes. The oil change place was closed so I added a couple of quarts after checking the level (i waited after the engine was shut off for an hour, there was a little oil on the dipstick but definitely needed more). After adding the oil and letting it settle it was at the appropriate notch per the owners guide. A couple of days ago, I bought gas at a station I dont normally use. The car was driven approximately 40 miles after fill up and before the noise started.
I took the car to get the oil change and was advised to get it checked if the sound didn't go away in a day. The auto place says their diagnostic tool won't work if my check engine light isn't on. Its not, and has never lit up. What to do next...I assume I shouldn't drive it anywhere. I remember reading bad gas can cause this sound, or a bad Co sensor (?) I am praying the oil light doesn't come on when it's already too late!

I have a 2000 chevy malibu that has not had a/c the past 2 summers. I'm trying to diagnose what the problem could be. When I start the car and then turn on the a/c by pressing the button in the car nothing seems to happen.
When I went to look at the compressor motor I could see that the clutch is not engage and the middle of the compressor is not turning. What to check without taking to a mechanic??

I just went into my garage and noticed pieces of my rear coil spring on the ground. 2000 Chevy Malibu LS. Question is, do I have to replace both rear coil springs? They seem to sell them in pairs.

My 1998 malibu starts most of the time, there is a continual light on the dash and according to the maintenance book from chevy, they are saying check your emissions system. Also on the times when the car does not start right away, the oil, battery light also goes on; the sound is rrrrr, weaker and weaker, wait 5 minutes and can start the car. This has been the pattern. Diagnostics say it is the crank shaft sensor..... I have already read your stream about crank shafts sensors.

When the driver side door is opened there is a clunk sound about half way through the swing. When the door is closed there is a couple clunks then a thud. The sound is coming from the front of the door.
What is causing this and does it mean big trouble soon?

I've got a Chevy Malibu with roughly 120K miles on it. It runs relatively well - when it starts - which is why I'm here, obviously. The battery is brand new with all the connections seeming to be great, so I doubt it's an electrical issue in that regard.
Furthermore, in cases where the car doesn't start, almost always it's on an incline where the gas tank is lower than the rest of the vehicle.
When it's either level or higher than the rest, it seems to start up fine, which has led me to wonder if it's something to do with the fuel intake (note that the car doesn't stall at all - it simply won't start in the adverse conditions I said here).

At 50 MPH and above, a popcorn popping sound occurs - varying fast and slow - only began after car was serviced. Can't find the source. Checked since it started and still nothing found - but new thermostat was installed, new gauge panel (due to car appearing to overheat but it was a faulty gauge), new wiper arms installed (thought they were the cause), running board rubber re-attached (thought it was flapping) - none of these were the cause because it is still occurring.

I've owned a 2008 Chevy Impala for about 7 months. It's at about 115,000 miles. It runs great...haven't had any problems out of it. So far. But there are a few things that concern me.
When I start the car, I hear this squeaking noise under the hood. I do not always hear this---it seems as if it may be tied with cold weather, like it's something that only occurs in the morning. But regardless, it seems abnormal. It subsides after a few minutes. The other thing I am noticing is that normally within the first 10 or 15 minutes of operation, if the car is at a stop light I'll hear some strange humming accompanied by vibrations. Sometimes the lights will flash faintly when this happens.
When I first purchased the car, I had a mechanic check it out. The engine, transmission, radiator, etc. were in excellent condition. I'm hoping that this is not anything serious, but I figure these are still sounds that I should not be hearing with a car in good condition.

I Have 17400 Miles on my Wagon and After Three Weeks in the Shop I am going to pick up my Car next Monday from the Dealer. I Did not have any Warnings Just Whistling Noise which was coming from under the hood.That was weary Loud Noise. I took my car to the dealer and they told it look like a bad Engine belt. After few days they told me my transmission is bad and needs to be Completely Replaced. I Read so many different stories on this Forum about Transmission Problems and i never had any problem till now.

I have noticed a whistling noise coming from under the hood. When I inspected it I notices suction coming form a small hole on the rear drivers side of the valve cover. From the little information I could find this is a PCV valve of sorts that is molded into the valve cover itself. The local dealership quoted nearly 850.00 for parts and labor. I spent a little time calling around. A VW dealer in a local city said that there was not a valve molded into the valve cover, and most likely this whistling was being caused by a hole in a vacuum line somewhere else between the engine and the firewall. This small hole is located above the where the crank case ventilation hose meets the valve cover. Is my local dealer correct in that it is the PCV valve that is part of the valve cover? Is this a fairly straight forward repair that can be done in the garage, and are there any other aftermarket fixes besides purchasing a whole valve cover?

Two weeks ago my car would not start, so I had a friend try and jump the battery. This battery wouldn't hold a charge, I took it into O'Reilly Auto Parts and they said the battery was shot. I put the new battery they recommended, the car ran fine for about 5 days. I took the battery back to O'Reilly and had them test the battery, it was too low to start the car, so they charged it and sent me on my way. The car ran fine for the rest of the day. The next morning the car would not start again, so I called the auto parts store and they recommended switching out my alternator. We switched out the alternator and the car fired right up, it ran perfectly (lights, heater, radio, etc) until yesterday.
While driving down the street, I noticed the radio head unit flicker, then it shut off. The car kept driving for about 2-3 city blocks, then all the lights shut off (dash lights, headlights, tail lights, brake lights). I turned onto a side street and the car couldn't go above 10-15 mph, it seemed. The speedometer and other gauges started going berserk, followed by a ton of dash lights coming on. The car basically rolled to a stop. I put it in park, turned the key to off and had it towed to my house. When I turn the key to accessory, all the lights work, as well as the heater and radio. But when I turn the key to start the car, a rapid-clicking sound comes from under the hood.

I have a 2004 Camry (2.4 Ltr engine) with 120k miles on it. 2 days ago a whistling/whining noise began after I had been running errands & restarted my car after being parked for about 20 minutes.
If my car has been sitting and the engine is cold (like when I get up in morning to go to work) the noise doesn't start until it gets to the 3rd line above the "C" on the temp gauge. It's a constant sound while idling or driving, except when I am accelerating. The noise seems to be originating from around the alternator, but hard to tell exactly. I have no Check Engine, battery or other indicator lights showing. Other than this mystery noise my car is running fine.

There is a whistling noise that is coming from under the hood of my Jeep. It is more noticeable on cold days. It temporarily disappears when my foot is on the accelerator or after I have been idling at a stop sign for 30 seconds. The noise starts again when I start driving.

I have a 2002 Accent that has this clicking sound coming from what sounds to be the left hand side under the hood. The click sounds like two marbles colliding. The car runs ok otherwise, but I would like to know about that sound.
I took a video, but its kind of hard to hear it. But if you listen close enough, you can hear it.

I have a 2000 Echo, Automatic, and I have a grinding sound that appears to be coming from the passenger side of the vehicle, under the hood. I had my A/C replaced, and new drive and power steering belts put in, 1,400 miles ago. I have noticed the sound is bad in park or neutral, seems to quiet down if I put it in Drive or Reverse while the engine is cool, and is particularly bad at highway speeds. I live 10 miles from my mechanic, on a highway, and am hesitant to drive it to them as it is all highway or rural roads (45 mph plus).
I drove it about 15 miles from when sound started (barely noticeable) to when I stopped and had it towed home. Belt deflection appears to be only about .3 in, manual I have calls for .43 to .51, but I may not be measuring it right....

When my vent is on the face setting, a grating/whistling noise emanates when the fan is on.This does not happen on the floor or defrost positions. The noise diminishes when it is in the face and partial floor or defrost setting. What may be causing the noise and how I could fix it.
