Astro - Chevrolet :: 1999 - Whirring Sound Increased In Proportion To Revving Of Engine
Jan 30, 2012
99 Chevy Astro with 93000+ miles. Only recent problem (one week ago) was left lights on for 4hrs on a new battery and almost completely drained battery, then, vehicle cranked without a jump. This AM started van to go to work and there was a definite "whirring noise" from under the hood. Popped the hood and sounded like coming from the brake master cylinder area vs. AC compressor area-hard to tell though. AC has not worked for 2 yrs. Noise increased in proportion to revving of engine. Likewise, noise continued while driving, although seemed to not be as loud when engine warmed up. Temp outside 34. Fluid levels OK. Where the noise is coming from? Also not sure if related or a concern: brake pedal has a slight "stick" to it when initially pressing the pedal, for ~ last 6 mths. give or take Brakes seem to work fine.

I'm working on a 1999 Chevy Astro 4.3L with an occasional crank, no start condition. On any given day, this vehicle will start right up and run fine, although some days it will start right up and have a part-throttle stutter; not a dead miss, but a stutter when accelerating that sometimes goes away. When it has the stutter, disconnecting the MAP sensor will cause the stutter to go away completely. I replaced the MAP sensor, but nothing changed. Today, it's back to its crank, no start attitude problem. The basics check out fine: good, strong spark at the wires, 60-65 psi of fuel pressure, and I even pulled the plenum to verify fuel is firing from the injectors. Everything seems to be happening as it should except that it will not start and run. I even tried doing the Passlock relearn procedure on it, despite spark and fuel happening when it should, one or both of which would normally be eliminated by the security system, but to no avail. What could possibly cause this here-today-gone-tomorrow no-start condition?

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?

Transmission comes out of gear and has a loud whirring sound when in reverse, but not every time. it has happened when driving at about 60 mph (twice) Sometimes it happens a couple times in a row sometimes it is ok for a couple weeks.

I have a 2004 Ford f-250 super duty 6.0 turbo diesel. I noticed yesterday that it was making a jet sound when i pressed the pedal and got louder as i increased the speed. When you let go of the pedal it goes away. I have asked around and some say it could be the turbo...the diesel mechanic THINKS it could be the fan clutch. The truck doesn't overheat and if i punch it i don't think i sense any loss of performance. All I know is that it makes this sound like a plane taking off.

When in idle the car is fine, however when revving the engine up to 2500-3000 rpm there is a puffing noise from the exhaust pipe area. What this could be?There is only on puff when reaching 2500 rpm... When I asked mechanic he said "it's because there is a small engine... Its a cheverolet cavalier 2001...

The air bag warning light is often, but not always, ON in my 1998 Chevy Astro. Unfortunately, it is ON whenever I seem to have a chance to bring it in for state inspection. My mechanic of many years has been unable to determine the cause.
(Note: An earlier problem with the battery draining was taken care of by turning the Dome Light button to the Off position and leaving it there permanently.)

My wife drives a 1995 Chevy Astro. It has twice now stopped running with no warning. This happened while driving down the road. The headlights and engine cut out, but the turn signals, power windows, radio display, and such have power. Once it sits for a couple of hours, it starts right up and runs fine for weeks.
Is there an electrical connection of some kind between the fuel pump and the headlights? What might be going wrong?

I've taken it to a half dozen mechanics, none can diagnose the problem. From a cold start the engine idles well, but once it warms up and the fast idle setting shuts off, it begins to vibrate quite a bit. I rebuild that included an all new fuel injection system, new ignition parts (including distributor, replaced at a later date,) new wire to alternator (the old one had cracked insulation,) and a new mass airflow sensor (swapped in from a parts van-no effect.)
Basically everything is new except for the sensors (crank sensor, idle air, throttle position, etc.,) and the fuel filter and pump. I'm not getting any codes, and at least two mechanics said it had good fuel pressure. It FEELS like a vacuum problem on a carburetor vehicle, but I had the vacuum harness checked as well, and everything seems to be in order.

I've recently been having battery drain issues with my 2002 Chevy Astro. After taking it to a local garage I was informed that nothing was wrong with it other than it needing a new battery. They put a new battery in and within two weeks of the van not being used the battery was dead. I did a bit of research online and learned that something may be drawing power while the van is off, and that I could do a fuse test with a multimeter. After performing this test I narrowed down the drain to being related to the following fuse:
19 Instrument Panel Radio: ATC(Main Feed), 2000 Series (Standby)
The only things that seem to be on this circuit are the radio, cd player and some elements of the instrument panel (e.g. odomoeter). I'd like to fix this problem but I'm sort of stuck as to what I should start testing from here. Today I disconnected the radio and cd player and tried performing the multimeter test again, with the fuse back in place. It appeared that there was still excess power being used with the vehicle off.

I have a 95 Chevy astrology van that I've owned for about a year. On occasion (about once a month) when I start it, the battery gauge stays in the red and all the lights are dim. After driving a bit I can stop the van and restart it, and the battery gauge normally shoots up to normal, and lights are all bright again. Don't have any problems outside of that, until now. For the last 4 day, my battery gauge has refused to pop out of the red, and lights are always dim. I can drive for a couple hundred miles and nothing changes. Last night, as I left work, it ran like it has been with low battery and then just died. There is no clicking, no "whirring" sound the starter normally makes, the battery just died. I'm on a very small budget and can't afford a shop, or both battery and alternator. What are your thoughts on this problem and where should I invest my money? As a side note, battery cables and posts are cleaned off, and are bolted securely. Nothing loose and no corrosion.

I just had a rebuilt engine put in my 1999 Chevy Astro. However, when I got it back the lighter and auxiliary lighters don't work. I checked the fuses under the driver's side dash and the one for the lighter looked good. I change it anyhow, and it still doesn't work. Anything else I should check? I am planning a long trip and would like to use my radar detector.

I have a 1997 Astro van and recently I shut the back doors (two door version) and now they will not open/unlock. I tried the power locks as well as the key. I read where you can take off the speaker cover in the door and reach thru and unlock/release from there. That did not work either. Not sure WHY Chevy decided not to put interior release handles. Any trick to opening the doors so I can see what the problem is?

I have a 2000 Chevy Astro van, and I have this problem that no one seems to be able to figure out, let alone fix. Occasionally the car with have all the lights inside and outside the car start to "pulse". The needle on the voltmeter will be noted to surge from the average just above 14 mid point on the dial on the meter face to over this in a pulsing motion, in time to the light pulsing. I have replaced the distributor cap, coil wire, and the car has been with the mechanic numerous times. His diagnostic equipment does not pinpoint the cause of this problem. What to try next?

My 89 Astro van is leaking red fluid when parked uphill (slightly) that drips from the u-joint closest to the transmission and only from the part that is in the yoke that goes into the transmission. I dropped the drive shaft thinking wrongly that there would be a bad seal where i thought the yoke went into i thought a second piece, but it is all one piece with a collar. When parked in the garage nice and level it did not seem to leak.

My brother and I noticed my engine making this noise today, I was under the hood and he was giving the engine gas with the car in neutral.
video of sound: [URL] .....
Sounds like air pressure being released, sort of a quick whistle or squeal just as he pushes the gas pedal, coming from under the hood somewhere.

In my 2007 Sonata, I hit a poorly placed high manhole cover in a dip in the road, in the dark, going 30MPH, whacked it good before I could adjust...
I then pulled the car over, it seemed to go dead, then the car did crank back up, the engine sounded much louder, like a loud rev/hum, not quiet like usual.
I next drove a mile to a c-store, transmission seemed OK, no leaks, did see a check engine light briefly, but it disappeared. Car cranked OK, headed home, same sound right at cranking and at moderate speed.
Finally, I jacked the car up on the front left, from research appears that the plastic engine shields got smacked good along the front and near the right tire and bent back quite a bit on the left side. There seems to be no other structural damage that my untrained eye could see, just one indention you'll see in a couple of the photos that I think is part of the car design at that spot.
Again, no leaks, no smoke, no caution lights of any kind now.
Photos are attached...
My Hyundai's engine now sounds like a Mustang! Hoping it's just the engine noise from these plastic covers now being bent/destroyed in some spots, exposing the engine and the typical noise you'd hear without them...
