Toyota - Sienna :: 1999 - Whirring Noise Coming From Center Engine Compartment?
Oct 25, 2011
I own a 1999 Toyota sienna that has 112,000 miles. For the past few months there has been a whirring noise that seems to be coming from the center engine compartment. It started quietly and now has increased in volume. It reminds me of a speedometer cable that is beginning to fail. I have taken it to my trusted mechanic for a diagnosis and he thought it was metal on metal noise from the transmission. I have owned cars for 40 plus years and have'nt heard of this type of tranny noise. What could be causing this? It makes this noise under power and when I release the accelerator the noise almost disappears. Also there is a clunking noise coming from the passenger front wheel after releasing the brake pedal when I come to a stop. I have replaced the strut,ball joint,and lower control arm bushing trying to remedy this. I cannot find anything else that is loose.

So my girlfriends Toyota RAV4 (2005) is making a medium pitched whirring noise from the passenger side of the engine compartment. (Same area where the serpentine belt and the alternator and all those goods are located.) The battery warning light is on, solid. I have not had a chance to take my DMM and check voltage but I suspect this is going to be a bad alternator since it is a noise consistent with the RPM of the vehicle and visual inspection of the belt is that it is still in one piece, not frayed, flexible, etc. I didn't rev the engine because I didn't want to freak her (the gf) out. My plan is to test voltage before she does anything rash like take it to the dealership which she is already planning on doing but the noise concerns me since noises tend to come from things that move which is probably an indication of some sort of mechanical failure and that tends to cost money. Luckily it's her car.

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?

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!

Rumble whoosh noise (her description,,, I am currently in another State) coming from my wife's vehicle in the front of the engine compartment. Closer to the passenger side near the water pump. Noise has been present for the last six months, but would always go away after it was warmed up. During winter (In Tucson AZ so never gets too cold), it is worse due to the cold weather. Previously only happened at low RPMs and ended to be worse when turning a corner.Today it occurred also after operation for a quite beyond starting of the vehicle, and is starting to sound like the failure of bearings. Also a burning smell was occurring.Just replaced both the water pump and the alternator, and the front struts. The water pump is not leaking but the old pumps leaks are still evident. The current mechanic trying to troubleshoot is stumped. Motor mounts are getting close to failure, but still appear to not be a problem. CV joints are fine. What to look at?

About a week ago I noticed this weird noise that sounds like it's coming from inside of the center vents area/console.
The noise definitely only occurs when moving, or at least it seems that way. At idle there is no sound. The sound seems to get a little louder the faster I go.
It's kind of a "whirring" sound. It's not really loud and if someone that had never been in the car were driving they probably wouldn't even notice it. It almost sounds as if I have the heating/ac fan turned up high but I don't. The sound appears even if I have the heat/ac fan off.The heat/ac works fine.
It may have nothing to do with the heat/ac but I'm wondering if something could have got stuck in the vents from outside?

Looking for some input on a recent "hissing" noise coming from eng compartment. It's only noticeable during initial acceleration, and sometimes at the beginning of gear changes. I am assuming its tubo and/or exhaust related, as I've noticed a strong exhaust odor in the cab as well. I wasn't under load when the problem started but i was under rapid acceleration. Not noticing any fluids or oils leaking. No warning lights have tripped, as of yet.

Having been on a long road trip, I noticed that every time I switch off the engine, there is a grinding noise coming from the engine. Took the van in to Toyota for a regular service, they could not find anything wrong. I then took it to an alignment place having replaced all four tires. They heard the noise straight away and think it is a worn bearing in the cooling fan in the alternator. 2007 Toyota Sienna LE FWD... The car only has 22,956 miles on it.

I have this weird noise that comes from the engine compartment and you only hear it when the A/C compressor is running and the gears are engaged while braking. It sounds like a low whirr that goes on for a few seconds. I noticed that if I shift into neutral and engage the brakes while the A/C is running the sound does not come on, also if I have noticed that there is no noise if the A/C is OFF. Could that be the compressor? the idler pulley? the belt tensioner??

Okay, my wife has a '99 Toyota Sienna with over 200 k miles. Recently, it has began making a loud exhaust noise. I looked at the exhaust system and cannot see any obvious holes. Also, her check engine light has been on for a while. I checked it and it said misfire in cylinder 5 (can't remember the code). Changed plugs and all, still the light. It also idles very high. There's no rotten egg smell that I can tell, but she does say that it seems like it doesn't have a lot of power when accelerating.

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.

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 no problem starting the car- it always turns over immediately, but every 1 out of 7 - 10 cold starts includes a strange noise from the engine compartment. Just as I let go from the crank position, I hear a sound similar to that of playing cards being shuffled. The duration of the noise is just a second or two, just like the time it takes to shuffle once.
It never has happened when the car is still warm. I had the Toyota dealer look at it, but they couldn't reproduce the noise- not surprising, since I didn't leave the car overnight, and even if I had, it still would be unlikely to happen when needed. The noise has been happening for a year or so, and it doesn't seem to increase or decrease in frequency due to air temperature or weather.
I did have a lot of corrosion on the battery terminals last summer and had starting problems then, and had the mechanic clean the terminals and check the battery, and the battery was fine, yet the sound continues, but no further starting issues. What might be going on?

I have a 2004 Prius that has a ticking noise coming from the engine compartment It speeds up and slows down with the idle of the engine or the pressing of the accelerator. Appears to be coming from the passenger side (US). No diagnostic codes have come up.

Upon arriving home a couple days back, a rather high pitched whirring noise commenced while idling. The pitched changed seemingly at random. So I popped open the hood and set about locating it, using the time honored scientific method of leaning over the engine, listening and moving around till the noise was most prominent. The noise has not recurred.
Seems to be coming from under the cover at the back. Area of interest circled in the 2nd & 3rd pics.
What is there, and if it might make a whirring noise. I am also getting a p0491 and 492 Secondary Air Injection Insufficient Flow, banks 1 & 2. Wondering if this could be the culprit for that as well.

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 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.

I would describe the noise as a whirling/vibration sound that can be heard as soon as the gas engine portion of the car kicks in (even in park) but gets louder and more noticeable as the car is in motion, especially at highway speeds (55 - 65mph). Opening the hood and listening to the engine block, the noise is definitely coming from around the area of the silver-covered portion by the driver's-side, which I believe is the hybrid synergy engine. The noise has gotten to the point where I really get bothered by it driving anywhere, and I have to turn up the radio to try to drown out the noise.

I have a 2007 Azera with a 3.8 engine. It has 16000 miles without any problems. There is a clicking noise coming from the engine compartment when accelerating. The noise only occurs when the engine is cold and seems to be more pronounced when accelerating quickly. I do not hear it when the car is idling.
