Dodge - Ram :: Loud Hum Coming From Engine Compartment When Idling
Jun 8, 2012
i just recently got a 1983 dodge B-150 van with a V-6 Motor when its idling you can hear a loud hum coming from the engine compartment. But when you start driving it goes away. But soon as you come to a stop it starts humming again i took it to the shop the mechanic found a few vacuum leaks.and repaired them all but could not find where the hum comes from.even after he did the repairs it still hums and it is very very irritating to hear. I still think it has a leak somewhere because when ever i turn on my A/C it blows out threw the vents just fine but soon as you start to accelerate the air stops coming out of the vents but if you let off the gas pedal fully the air comes back on which is a killer in this Oklahoma heat.

I have a 2009 Corolla 1.8 with 18,000 miles on it. My wife mainly drives it, today after getting it washed, I was driving and noticed a very faint noise from the engine compartment. Seems to be coming from the passenger front. The sound is something like grr grr grr.... I made sure it's not the wheels by putting the car in neutral and giving it gas which made the sound audible (I can also hear it while idling).
I had my wife sit in the car with me, and she couldn't hear anything, but I can, so I'm afraid when I go to the dealer he will say the same "I can't replicate the noise". What it can be?

I am experiencing a loud noise which is getting worse from inside my engine compartment. I took off the heat shield assuming it was coming from the exhaust manifold but it is not. It sounds more like it is coming from the intake manifold. Now I would assume it was the intake manifold issue that has been described in many threads but it is not a vibration or clanging sound. It just sounds like air is escaping from my intake. What baffles me is that the sound is loudest in drive. Then neutral is the next loudest, then reverse there is very little unordinary sound.
I hear it a little bit when I am going like 15-20 MPH in reverse and let off the gas to decelerate. There is a noticeable noise increase just at idle too. I checked and all fluid levels are good. I changed the tranny fluid about a month ago and according to the dipstick it is right on where it should be. The sound is increasing and I am worried about what it may be. It sounds as if it has an exhaust leak but I do not see anything.

There is a loud ticking noise coming from an undetermined location in the engine compartment (sounds more like behind the motor). It starts on cold-start, lasts approximately a minute or so until the engine heats up. Driveability doesn't seem to be affected, and the engine doesn't have any additional weird symptoms. Some other VW owners have suggested changing the cam belt and tensioner to fix this problem, but the car has only just turned 45K miles and can't imagine that it would fail so quickly.

So I drove my car about a mile to a friend's house and when I went to start it back up 10 minutes later, I got no start and no crank. Just a single loud relay click from the engine compartment. Tow truck tried jumping it and then thwacking the starter solenoid to try and get it going. No dice. Battery seems all good.
Had some interesting things go wrong the day before which may be related to it. First, I was tracking my MPG and fuel trim on a highway trip and the trim and fuel consumption data just stopped coming in. Speedo and RPM data was still coming down the OBDII but I just assumed that my reader took a ****. Later that night I noticed that the lights on my climate control (the manual kind) went out. Tapped on it and it came back on, but only briefly. The bulb looks shot.
No engine strangeness on the drive over or earlier in the day. I drive it most every day. Has 215,000 miles on it.
I'm guessing either a short or bad starter. FWIW, I've also been experiencing the typical starter whine after starting. Was meaning to take it off and grease it. Not sure that has anything to do with it. I also tried rotating the crankshaft to make sure the engine wasn't locked up and it does turn, albeit not incredibly easily. It does have oil on the dipstick.

I'm pretty sure I made a mess of things. My Serpentine belt was all cracked and making noises while idling and driving. It was time to replace it. It's a long story, but my auto mechanic told me to drive my truck for a week and then give him a call. Well.... I didn't do that. My battery went dead and I charged it up and it lasted a month. Yesterday, it wouldn't start so I bought a Serpentine belt and installed it. As far as I know, I didn't damage anything while I was working on it.
The battery was still dead and I charged it, however, the key was turned on while I was charging it. I don't know how I did that, but I did.
The problem I'm having is that the engine is now idling at 2000 RPM. I scanned it and there are no codes or pending codes.
Today, I went out and drew a diagram of how the belt is routed and it's the same as the diagram under the hood. I had a friend take a look at it and he agrees that I put it on correctly.

I started noticing some strange sounds coming from the engine compartment after shutting off the car ( a 2007 with 90K miles). It's different from the hum for several seconds that I often hear after switching off the car. This one is a squeaky rough sound like a small motor wearing out. I think it's from the driver side of the engine compartment. Is that where the inverter pump is? This car didn't have any record of needing the inverter pump changed for the recall as far as I could tell.

First off it's a 2008 Prius with 80K on it.
There is a new sound that has started coming from the front of the car in the engine compartment or even lower. It is a turning turbine like sound that is mostly obvious when driving at 60 mph, but my guess is that it is always there, but not as audible at lower speeds. The air and heater are both off and have no effect on this sound. The only thing that could have had anything to do with it is that a day or two before, the tires were low so I filled them to 40 psi. The other thing is that it clicked over to 80K the last week and the friendly red maintenance required light came on.

i have an 06 phaeton with 32 k miles . drove home with no problem at all, no engine shake, zippo. then i put my car in the garage and 10 minutes later smelled like a fire. i pulled my car out of the garage, and the yellow light was flashing and the engine rocking like crazy. shut it off in less than 10 seconds. under the hood, the front left spark plug cover and cable that runs across all four was almost completely melted. the cable was burned right thru. the black caps that cover the plugs-- the front right one only was melted severely. Do I have a blown engine...

I have a 2011 RAV4 with 122,000 miles. For the last few months I have heard a fluttering noise coming from the engine compartment, usually at in-town speeds when I step on the accelerator gently, for example to maintain speed on an incline.What could this be?

I can hear a drone at freeway speeds coming from the engine compartment of my 99 Passat 1.8. I don't know whether this is normal, but it seems like the down pipe has a resonance/vibration. How to reduce this? Test pipe? Header wrap? Or is there something wrong that I have this buzzing?

So, I have 100K miles on a 2007 4Runner (V6) and after having my radiator flushed at the Toyota dealership service dept, I get my car back and now hear a low rumbling noise coming from the engine compartment. I hear this noise every time I turn on the air conditioner, and sometimes even when it's off.
I took my car to Toyota today and after getting the service advisor to acknowledge the noise, I get a call 2 hours later saying, a) that no noise was identified by the technician; b) nothing wrong with my car; and c) I can come pick it up.
It ain't my imagination. Clearly, something is wrong. What it is? Should I take it to another service department? This kind of thing makes me crazy!

I have a 2001 Pontiac Grand Am with about 160K miles on it. Over the last month or two I have noticed a persistent ticking noise coming from inside the engine compartment. It sounds like it might increase in frequency along with the engine speed. It is loudest when I pull up in a drive-thru or next to another car and roll down my window. It is audible when sitting or while moving. Doesn't seem to make a difference if the car is hot or cold. I checked the oil and it appears to be full. It sounds like it's coming directly out of the engine block itself. I get the oil changed every 3,000 miles like clockwork.

I first noticed a strange noise coming from the engine compartment a day ago. I had left the car to sit in the sun for a few hours. When I got in the A/C was set to on and the system was on auto. I tested to see if the noise went away when I turned off the A/C and it did. I turned it back on and it returned. I know the A/C operates at different speeds based upon cooling needs and that it can get sort of noisy but I didn't think that it could/should get this loud. The system seems to begin working quickly and it does seem to put out cold air. If the noise is unusual do you think that it indicates another underlying problem in the A/C system?
Just to clarify, the ICE is not running in the video. The cabin fan is set to low and the temperature is set to low. The person in the car presses the A/C button and the cooling fans in the engine compartment come on as well as the A/C unit. The sound gets louder a few seconds in. Here is the link to the recording I made of the sound.

I am the 2nd owner of a 2001 Chrysler Town and Country Minivan Limited. The vehicle is in very good shape and I service it every three months and have the tires rotated every six months.
Just recently I have been having a problem with it not wanting to start. I have had a bit of a squeal coming from the engine compartment and know it is the serpentine belt that needs to be changed out before it gets bad (I have only heard the squeal probably three times since December 2012.)
I would rather buy my parts and have the mechanic put them on instead of him buying them and charging me double.
My question is...do you think it is only my belt or should I think in the direction of the Starter or something else. After about threee or four tries it will finally start.

As I accelerate, there is a humming noise that comes from the transmission area of the car. It does not make the noise when I am in idle, nor if i put the transmission in neutral and rev the engine.
When driving slow the noise is very subtle. As I accelerate faster the noise gets louder. The noise becomes the loudest at 60 mph. Above 60 it seems to calm down some. The noise is like a constant, deep humming sound. The noise gets softer as I slow down and then is gone when at idle again. To me it seems related to the speed of the tire or the CV half shafts turning or something rubbing in the transmission as the car goes faster. However the sound doesn't change when the transmission shifts. It stays constant and only gets louder as I go faster and then softer as I slow down.
While driving and turning hard to the left the sounds almost disappears until the car straightens out again. I have replaced the struts on all four wheels and this seems to only have caused the sound to get louder. I have also inspected the CV joints. There doesn't seem to be any cracks or signs of wear to all 4 joints. And I repacked the bearings.
The only other things I can think of is the cv half shafts are actually bad and need to be replaced. Or the motor mounts are not aligned/worn out and need to be replaced. Or the kickdown band and low reverse band on the transmission need to be readjusted. Or the transmission is has a problem (however it doesn't slip when driving).

I have a 2009 Toyota Matrix S. There is a rattling noise coming from my engine compartment whenever i drive 60+ mph. It sounds like it's metal on metal. Nothing is loose inside. I took it to the dealer and they told me the water pump bearings were bad and replaced my whole water pump. That didn't resolve my problem. The rattling is still there.
