Chevrolet :: 2001 - Popping And Whining Sound
2001 Chevy impala with 2 problems. First, I get a whining sound that lasts about 1 min after the car has run for about 5 min, and as soon as the noise starts the engine temp goes up (high, but not in the red). It's not the accessory belt, revving the engine doesn't do anything and either does putting the car in neutral. I can get the tone to slightly change by turning the a/c on and off, but it doesn't stop the whining. It sounds like it is coming from the radiator fan and when I tapped the one fan the other day, the noise stopped, not sure if it was just a coincidence. Second, I get a popping noise coming from the front of the car when accelerating. I don't think it's the shocks because I compressed the shocks by bouncing on the hood and got no noise.

I found a steal of a car for my son, a 2003 Monte Carlo SS. The car had been hit slightly in the LF corner. The car needed front brakes, so I bought a package off Ebay that had rotors, pads, and wheel hubs. I replaced the LF wheel hub when we did the brakes and kept one for a spare since the RF felt good.
Shortly after replacing these parts, the car started to make a popping sound when you would turn right. The popping sound is much like an exhaust pipe dragging on the ground. We checked to make sure the was no contact with moving parts. After reading several forums, we decided to replace the LF hub with the spare we had. This did not fix the situation, so we put the first replacement LF hub onto the RF. Still no fix.
After this we decided to take the car to a empty parking lot and drove in circles trying to find the source of the noise. We discovered that the noise would go away if the car was put into neutral. We were still unable to locate the source of the noise.
So I decided to jack the car up and put it in gear and turn right. The noise did not occur with no load on the tires. However the u-joints on the axles were making some excessive noise, so I put in a new set of axles. Again this did not fix the noise. Now thinking the source must be in the differential.
Well two days after putting in new axles, the transmission went out. This will surely fix it, right? Well the mechanic that fixed the transmission said the pump had gone out, and it appeared the differential was creating shavings that caused this situation. GREAT WE FOUND THE SOURCE. Not so much!
Car still makes noise while turning right after replacing the transmission. I have driven myself crazy trying to find the source of this noise including riding in the engine compartment while my father drove in circles in the local high school parking lot.
Chevrolet - Malibu :: 2000 - Whistling Sound From Under The Hood?
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.
Impala - Chevrolet :: 2008 - Vibrations And Squeaking Sound From Hood
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.
Chevrolet - Silverado1500 :: 2000 - Buzzing / Whining Sound Coming From Under The Hood
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 ...
View 1 RepliesGolf IV R32 :: Popcorn Noise At Low Speed - CV Joint Failure?
Last night while driving home I had noticed a slight popping noise when starting from a stop. It got worse by the time I was 1 mile from home. Sounded like popcorn popping in my passenger wheel well. I can feel it in the steering wheel. Limped home with flashers on. Investigated this morning:
1. Wheel lugs are tight
2. No ball joint movement in/out
3. Wheel liner clearance OK
4. Sway bar, links & bushings OK
5. C/A bushings and bolts OK
6. Strut bolts OK
7. Brakes, rattle clip OK
8. CV Boots OK (hence I question a cv failure)
9. Wheel weights appear OK
10. Upper Strut mounts seem OK
11. DG skid plate and splash guards OK
12. Coilover span nuts tight
13. Subframe bolts & steering rack tight
One thing I didn't do was push down on the hood / upper strut area to confirm shock is okay. I'm running pss9 coilovers, C/A bushings replaced at 50k miles, strut mounts (INA) @ 75k. Car has 94k.
Impala - Chevrolet :: 2008 - Hood Won't Stay Up
I have a 2008 Chevy Impala that I've owned for going on six months. It's treated me very well. I'm just now getting ready to give it a nice wash/interior cleaning this evening, but I noticed while cleaning under the hood just now that I cannot get the hood to stay up on it's own. I'm not sure what the issue is. I keep nudging it gently, but that's not working. As recently as yesterday I had the hood up when I was checking the oil...it stayed just fine.
Of course, the pre-2014 Impala generation has hoods without the manual supports. So what might the problem be here? I figure this car is a little new to be having a problem like this.
Impala - Chevrolet :: Not Starting Unless Tap On The Throttle Under The Hood
My 2000 Chevrolet Impala doesn't want to start unless I tap on the throttle under the hood--battery seems okay, as the heater, radio, lights work, but starter won't even click unless I do this. Know why?
View 5 RepliesChevrolet - Lumina :: Detached Clip / Wire Under Hood
I'm very ignorant about car repair, so I attached a couple pictures showing a "clip" (the gray headed wire at the bottom of the picture that is not attached to anything). My car recently died, I suspect due to a drained battery, and I hadn't noticed this before.
Further info: it's a 92 Chevy Lumina and the battery is underneath the area pictured. I've tried to jump it, but can only get it to crank a couple times before failing.
Chevrolet - Silverado :: 1999 - Running Rough / Popping / Backfiring And Lost Power
My wife was driving the 1999 K3500 7.4 model ls crewcab truck home the other day and out of the blue it started running rough popping and back firing and lost power. It had a major tune up about 40,000 miles ago. It sometimes has a hard time cranking to start, but once it starts it idles really rough and pops and smells like it is running rich. I thought the distributor cap but it looks fine, could it be a sensor?
View 2 RepliesCavalier - Chevrolet :: Coolant Light Is On Constantly And Smoking Under The Hood
I just bought a chevy cavalier z24 2.4 liter engine. Yesterday my coolant light kept going on and off at different times so I added coolant to the overflow reservoir as shown in the car's manual. Today the coolant light is on constantly and it was smoking under the hood. I stopped and there was a big puddle of coolant was under the car. The car is not overheating. Did I put too much coolant in it or could it be a problem with the radiator?
View 14 RepliesChevrolet - Aveo :: 2008 - AC Stopped Working / Fan Under The Hood Cycles On And Off
Mother in law's 2008 Chevy Aveo had the ac stop working. I put gauges on the vehicle, and it was low on freon. I recharged the system, and the ac now works. Problem is, the fan under the hood cycles on and off. On every other vehicle I have had, the cooling fan should stay on the entire time the ac is working. This fan comes on for a few seconds, then shuts off. Every time it shuts off, my high side reading approach 300 psi. Then it comes on and high side drops to 200 psi. Is there an obvious reason that this is happening? Is it supposed to happen?
Forgot to mention, the ambient temp is 80 F, low side is 40, high side is 200, dash temp is 55 F. (A little high)
Chevrolet - Astro :: 1999 - Loud Rattling Noises Under The Hood
My 1999 Astro van recently started making LOUD rattling noises under the hood. No previous problems, ran great up till pulling into my driveway. It does have 160,000 miles on it, but has always been excellently maintained. Towed it to dealership where they told me that "by the sound of it" it would need a new engine. This van is fully loaded, power everything, leather interior, paint job is great, everything works. Breaks my heart that I may have to junk it. So, the big question is, junk it or get a new motor?
View 14 RepliesImpala - Chevrolet :: 2009 - Whining Noise Coming From Under Hood
So I have a 2008 Chevy Impala LS that hasn't given me any real problems. I had some battery troubles recently that were the result of me leaving the parking/security lights on for 10 consecutive hours, but overnight-charged the battery and was good-to-go after that. But it seems like RIGHT after that was when the whining noise started.
It seems to be related to my power-steering system. I know this since the whining seems to pick up with acceleration and turning. However, I checked my power steering fluid and it did not appear to be depleted at all. I did notice, however, that it seems to be a light greenish color...which from doing a google search, I've gotten the impression that it's probably not supposed to be that color.
What exactly is going on here?
Impala - Chevrolet :: 2001 - White Smoke And Pop Noise From Under The Hood On Driver Side
I am having a problem with rough starts/ normal starts. This issue is intermittent. Once in a while when turning on the car I'll get white smoke and a pop noise from under the hood on the driver side. It smells electrical in nature. Other times like 80% of the time it starts normal. Also I have an issue with some of the cluster panel being lit while other are dimmed slightly. What is the cause of this problem? Where should I start to look to fix these issues? 2001 Impala LS 3.8L .........

When i drive straight and i let go of the gas the car kinda jerks always then the pop sound comes from passenger side.. or when i turn, then drive straight i pops. I'm thinking it might be a bad cv joint or bearings..? or i heard that the FK coils it self-make weird noises.
Chevrolet - 1500 :: Truck Makes Toot Noise From In Front Of Driver Under The Hood While Accelerating
Six months ago we purchased a '91 Chevy Pickup and 3 months ago the truck started to "sneeze". Sometimes while accelerating the truck makes a "toot" noise from in front of the driver under the hood, and with the noise I have a momentary loss of RPMs. This can happen a number of times in a row, making pulling out on to busy streets difficult and dangerous. Most of the time, I take my foot completely off the gas and then re-apply it, and the issue goes away. It happens both with a cold engine and a warm/hot engine. This problem started when it was cold out (around 10 degrees Fahrenheit) and the mechanic I talked to about it thought it was the E10 87 gas I was putting in.
I switched to a 97 octane/no-ethenol fuel and the problem went away, until about a week ago when our temperatures finally broke 50 consistently. The problem is back and with it is a minor fluctuation of RPM when idling in neutral. The truck also created a new symptom, I was driving at about 50mph and the truck acted like it slipped on ice... I had evened out my speed and the truck seemed to start coasting then got back to driving at speed, it jerked the whole truck, like driving over a patch of ice. I don't know if it has anything to do with the original problem but all symptoms may be the same thing....
The truck is a 91 Chevy 1500K, 5.7L V8 and has 74,000 miles (mostly highway towing). It had been sitting 2 years, not really being used, before we bought it. We had the fuel injection system cleaned when they did the oil change, right after we purchased the vehicle.
Chevrolet - Sonic :: Air Valve Stuck Open Code / Smoke Or Steam Coming From Under The Hood
So for the past week or so, I've been having problems with my cooling system. (May or may not be related to my air valve stuck open code, just thought I'd mention it.) First thing that drew my attention to the problem was smoke (or steam) coming from under the hood, I let the car cool off, and drove home. During this time I also noticed the heat stopped working. I went to get some coolant in another car and filled it up. Smoke went away, and heat started working again.
Later the same day I checked the reservoir and it looked low so I figured the radiator sucked all the coolant up, so I refilled the resivoir tank. I spilled a nice amount when doing that, and the steam came back. It cooled down again and no more steam, figured it burnt off. The next few mornings on my first drive of the day ONLY, I saw steam. Thought it was the condensation mixing with the leftover coolant that I spilled since it didn't happen at all until the next morning.
Today was the first time it started steaming at night, and the heat stopped working again, even though the reservoir level was mostly full. I let the car cool down, and then I added more coolant and the heat started working again, no more steam either. Looked under the hood once I got home, abt a 20 min drive, resivoir was nearly empty even though car was still warm. No visible leaks on the smaller reservoir hose but there are puddles under the hood.
I've read it could be a leak of course, but also the Cap could be preventing the right pressure to suck fluid back in radiator after expanding into the surge tank, or something causing the tank to boil over....
Car is a 2013 Chevy Sonic with 68,000 miles. Coolant has never been drained/refilled since I bought the car new in 2013.

Camry 2012+ :: Sunroof With Popping Sound
It seems that many 2012/2013 Camry owner with sunroof has popping sound issue. Based on reading threads that are already out there it either happens right away or after 10,000+ miles of ownership when outdoor temp gets cold or driving over a bump. What is not clear is, too me, if this issue happens to majority of Camry owner with sunroof or minority. I for one own a 2013 Camry with sunroof with almost 3000 miles on it but I do not have this issue. Was wondering if Camry owner with sunroof can chime here whether or you have this issue and how many miles you have on the vehicle. What percentage of Camry with sunroof are having this issue.
