2000 Nissan Pathfinder Le for about three months now it has been making a chirping sound from under the hood you have changed the belt and tension pulley it still has a high pitched squealing sound?
Answer . You needed a new belt \nMaybe the pulley that was replaced is the wrong one therefore, the new belt was put on incorrectly.
What would cause a squeakingchirping noise under the hood of a 99 Tahoe Belt belt tensioner and idler pulley have all been replaced Could it be the alternator?
Answer . Did you change out the belt? I had a chirping and squeaking on mine and my 95 Impala and I couldn't isolate it so I went with the cheapest repair, a new belt and low and behold it solved the problem. As soon as I hear a noise now, it's belt first then more expensive parts last! Good …Luck (MORE)
Why is it that my 1994 Geo Prizm engine makes a strange high-pitched squeaking sound when under load at lower rpm This noise increases with AC on. Maybe a loose drive belt Engine is 1.6L I4 16valves?
Sounds like a slipping belt. Could be a component not turning, or turning too slowly.
Why is your 2003 mitusbishi galant making a high pitched noise when it starts after having the belts changed?
Answer . Sometimes this is normal for a new belt until it breaks in alittle bit. If it is still doing it then the belt could be too tight or just a little too loose. If it is too loose the tensioner might be bad and need replaced. If it is too tight it is possible to have the belt routed wrong. Th…is would cause it to be too tight. You could try using some Belt Dressing spray and spray the pully surfaces. If it gets better than your belt is a little too loose. Sometimes this spray will solve the problem. Good luck. (MORE)
On my 89 XJ it's the 4 roof mounted deer whistles positioned below the front roof rack bar. Whistle about 55 - 60 mph. I travel 60,000 km per year. Yes the deer whistles do deter the deer. It could be your side mirrors or a trim strip, per haps at the window. Or some weather strip leakage at the doo…rs. Do you get the whistle a certain speed range? How are your wheel bearings and diff. lube. Is it a whistle or whine? Have a passenger search for the source, or if you trust them driving your jeep you search for the source. Have you accessory lighting or winch mounted up front? The whistle is some thing vibrating in the wind at a resonance frequency. You need to find the source by following the sound. (MORE)

Where is the noise coming from under the hood of your 1996 grand voyager van after you have change out the belt the tenisor wheel and idle wheel?
Answer . The noise can be 1 of acouple of things, could be that the belt is on slightly crooked... or dirt being on belt and tensioner pulley or the tensioner pulley is on slightly crooked causing the noise... the belt wont slip off, but it will just make that noise... just put some oil on the b…elt and that would be enough to keep it lubricated and noise free... or could take it all back off and put it back together, checking to see if everything is nice and straight, and dirt free.

You have an 07 1200 sporster low and it makes a high pitched noise in any gear mostly in low rpm and not accelerating much it sounds like metal rubbing and from the rocker area it is under warranty?
try checking the gas tank mounting bolts. the one under the gas tank closest to the front of your seat was where the high pitched noise was coming from. tightened it and problem solved. it did sound like it was coming from the engine ,but it wasn't.
Are you getting this whistle when the car is stopped? If so, shut the radio off and see if it still exist. If it does, then shut the blower/fan down. If it goes away, then it is more than likely the bearings on the blower motor.
1999 Chevy trailblazer and when you turn the heat on there is a louder then usual noise coming from under the hood the heat still comes out but it is humming loud when you turn it to high what is it?
Answer . I'll take a guess and say your blower fan is about to crap out-just try humming louder,just kidding, but if you start to smell and taste anti-freeze and there is no heat, that would be your heater core.
Answer . The noise can be comming from the weather stripping around the door, the wind passing past the antenna or from the wind around the luggage rack on acceleration.
There is high pitch noise from the hood of my car - mercury sable 1998. Trends to get worse at higher speeds.?
Sounds like it is your belt. Look under your hood and find a belt that seems to be routed around lot of things, up and under, a long belt. Look and see if it looks worn, and it so, this may be your problem, you need to have that belt changed out if so. Could be a bad bearing in one of the belt dri…ven accessories i.e. Alternator, Water pump, A/C compressor etc.. Two things come to mind: The belt may be loose or a bearing may be bad on one of the pulleys. Either would cause a high-pitched whineing noise. (MORE)
Your car makes a high pitch whistling noise when you let off the gas and it goes away when you accelarate.?
You have a leak in your vacuum line. The best way to fix it would be to locate the line and change it or if you cant find the line either replace individual hoses (vacuum lines) or bring it to a dealer and have them repair it.
Why would the timing belt make a whinning noise after being replaced in a 02 Xterra told it was normal. i don't agree?
It is not normal for a timing belt to make any noise. It is whiningbecause something is out of place. It is either under too muchtension or there is not enough lubrication.
02 mountaineer with a bad noise from the belt you replaced the belt the idler pulley and the tensioner pulley any ideas?
If you have replaced the belt, tensioner and idler pulleys, then the problem could be the water pump bearing, alternator bearing, camshaft bearings, power steering pump or any of the items attached to the serpentine belt. You may try to isolate the sound by listening with a length of rubber hose …and place it near the areas where the 'noise' you hear may be emanating from. Just be careful not to get the hose too close to the engine fan or belts as it can get caught and cause damage or injury. (MORE)
yes the very fast vibration of high frequency sounds can rip your eardrums or pulverize the ossicle bones
you likely have a vaccum leak- check the big 3/8 id hase leading to your vaccum booster for your brakes- it might have been pulled out. if not look around for cracked or broken vaccum lines- if no avail get a can of carb cleaner, start the engine & spray alon the throttle body, intake, vac hoses, et…c. when the idle change you've foun your leak- fix it & you should regain your lost power- as your engine is receiving un metered air and is going lean- you should be good to go- good luck!

Is there a tranny shift sensor on a 2001 gmc savana 2500 because my engine is revving high before shifting any thoughts?
4l80e or 4l80-e is the tranny they use and they do have to of them, one is for the speedometer gauge and one tells it when to shift
grinding noise from the fan is a bad bearing on either the fan or the water pump.have it checked before it lets go and goes thru radiator
My husband did a do it yourself oil change on my escort now it makes a loud grinding noise and there is smoke coming from under the hood to the right of the engine any ideas?
divorce him & marry a mechanic. Failing that, check the engine oil. If it's way overfull, he drained the tranny.
It could be your shocks, connection between you tire or your brakes could need a good oiling.
It is very likely that the bearings in your fan are failing. You probably need to replace the fan.
The air conditioners intake it under the passenger side dash all the way in the front. Some times receipts or plastic bags can get sucked up there and cause the noise. -Gary
Why does the toilet make a loud high-pitched whistling noise for about 30 to 60 seconds after it is flushed?
Usually the water filling up the flush valve in the tank. If it's bugging you, you can change the flush valve to a new one.
Generally that metallic sound is really coming from your front disc brake sensors, they make a squealing sound when they wear down to a certain thickness of the brake pads allowing a small metal bracket called a brake sensor to rub upon the disc brake rotor in order to aleert the driver its time for… the brake pads to be relined.. Other things may be belt noise under the hood(loose, worn, etc.) or a pulley(idler/adjuster pulley with worn out bearings) bad alternator bearings, water pump or anything that may have loosened up and is hitting the moving parts in the front of the engine. (MORE)
P You're going to have way more detail than that! If it is an electrical sound (Fast buzz) then look at your plug-wires in a dark setting. If it's a firecracker pop sound, then inspect your manifold for cracks or blown gasket or leaks.
My 1999 Chevy express 1500 has a squealing under the hood you have tried changing the belts belt tensioner and a new idler pulley and the noise is still there does anyone have any more suggestions?
did you check the water pump, alternator and anything else that might have a pulley?
88 Chevy K1500 Truck What would cause a high pitch screeching sound under hood it is not the serpentine belt but seems to be coming from an internal pump or bearing?
You need to remove the serpentine belt, And then start engine and see if the noise goes away with the belt off. That will eliminate all the things that the belt runs. If your noise is still there with the belt off, then ask your question again saying that you have removed the belt and you have a h…igh pitch screeching sound. Then wi'll see what we can do for you.

\n. \nA dog whistle is very high pitched. Typically, a dog whistle is within the range of 16,000 Hz to 22,000 Hz. Humans can only hear frequencies between 20 and 20,000 Hz while dogs hear frequencies between 40 and 60,000 Hz. That's why these whistles seem silent or nearly silent to humans but do…gs can hear them. (MORE)
Since this is very unspecific to location, I am going to assume a hole in a air hose somewhere. Or maybe you timing belt is bad.
I'm not a mechanic but these are the culprits that I've experienced:. 1. If you turn off the AC and there is no more noise then:. a. Your compressor belt may be loose. Check the tension of the belt near the AC compressor. If the belt seems loose a +/- 1/2 inch give then it's too loose. If the Belt… is so tight you cant move it an 1/8th inch, too tight.. could damage pulley.. b. The Compressor pulley might be bad. Have a mechanic check it. Compressor parts can go bad and they work hard in extreme hot states like Texas. If it's not a belt, I'd pay to have the compressor checked. If you dont then live with the sound and when the pulley dies, deal with it? :) (MORE)
There are many small transformers and electronic oscillators in a CRT monitor which scan the electrons across the screen, blank them at the end of a line and return the beam to the left of the screen in order to start the scan again. These transformers have alternating currents flowing through them …which make the ferrite cores 'chatter' at the same frequency. This frequency is about 18,000 cycles per second which makes this audible noise. (MORE)
I have a 2008 Dodge Caravan that whistles when either I reach a speed between 65 - 75 or when a strong wind comes from the front left corner of the vehicle. Took it to the dealership when I noticed the front fender came loose where it meets thefender well. They replaced the fasteners to reattach the… fender. Did not make a difference. Since I travel for my job I had plenty of time to analyze the problem. What I think is happening is the wind is causing the headlamp on the driver side to vibrate at a high frequency causing the sound. Think of when you have the brake rotors turned and they put a large rubber band around the outer edge of the rotor to prevent a very high pitched squeal. (If you've never heard this before, it will cause you to put your fingers in your ears!) So I used the same principle and wrapped a layer of electrical tape around the top, sides, bottom and outer edges of the headlamp to decrease the vibration. This has solved the problem for me. Good Luck! (MORE)
The most common cause behind a high pitched noise under the hood is the drive belt. if it is worn out or loose, the wheels will slip, creating the noise. I would check to make sure the tensioner isn't bad. If it is, this could be causing the looseness. If the tensioner is fine, then just replace the… belt. (MORE)
Why would 2 different mechanics change an Alternator belt twice on Toyota diesel van which is OK for 1 day then high pitched screaming noise occurs when going under 70 kph?
sounds more like a pulley is about to go out. Since belt is new, spray a small amount of wd-40 on the pulleys, when whining stops, you have found the culprit.
This question has information missing. Make model year engine are all required. In short my Diesel has a turbo whistle all the time that is normal Many Diesels make this noise. Whistles are often wind noise and caused by other than mechanical faults, so this car needs to be shown to a qualified pers…on and have that person figure out the source. (MORE)
Are there any recalls on 2004 Chrysler pacifica having to do with clicking noise under hood while driving or standing still?
If you call your local dealer with the VIN number they will run it in their computer and check for any open recalls.
because the vibration is so fast your ears hurt low pitched sounds vibrate slowly and doesn't hurt
If it is coming from the radiator or the hoses this would mean your antifreeze is boiling in the lines. I would recommend first changing the thermostat and bleeding the air from the rad lines.
Yes if a dog hears a high pitched noise it will go crazy try this out with a whistle and it is because of the frequency.
well obviously a little bird hit your wind shield and slid down under your hood and got stuck between the engine and oil tank... this exact same thing happened to me
Some of the reasons that there could be a noise under the hood when pressing the gas follow: . Clattering: This in most cases could be from the valves getting too hot. This could be any cause, from the car over heating to the catalytic converter being clogged. If you are hearing a clattering nois…e, you need to take it to your trusted shop or the dealer to be assessed and fixed. . A ticking: This in most cases is the injectors getting old and wearing out. There isn't a lot you can do for this, but you can lower the volume of the noise and add a little more life too the injectors by adding some Lucas or sea-foam fuel treatment to your gas tank once a month or every third or forth tank. . a knocking: This is a more serious sound. This can be anything from a broken rocker arm to a spun rod bearing. either way it is a serious thing. If you are hearing a knocking, you need to take it to your trusted shop or the dealer to be assessed and fixed. (MORE)
Depending on what is driven by the timing belt, it may be a few things. Usually the tensioner or water pump, but it could also be a glazed belt or even the cover rubbing on the belt

Because a dolphin's ear frequency is higher than a normal human's, so they have to have higher pitched whistles so the dolphins can here them better. Plus, high sound frequencies can travel underwater easier so dolphins can hear them.
Not likely. A bad O2 sensor would illuminate the check engine lightand the engine performance would suffer.
