Squealing noise?!
Car is making a squealing noise! Awful!
My car squeals when I'm driving sometimes and it always squeals when starting up. After I've been driving for about 30 seconds it stops. Replaced the belt and the tensioner. They're brand new! It squeals worse when I'm turning, but not a power steering whine sound. When I'm turning the wheel and my car is still of it squeals my steering wheel jumps to the same rhythm as that squealing. My car has 185000 miles. My car has an automatic transmission. BELT DRESSING MADE IT WORSE IT ISNT THE BELT

Hey there. You have a binding accessory on the engine like the A/C compressor or pulley, power steering pump, or an idler pulley. You should first test the computer to see if the power steering pressure switch is activating by scanning the computer data to see if switch is working. If it is okay, then one of the components are binding and would need to be diagnosed by removing the belt and checking each component for binding. The car may also need a power steering pressure test. If you would like to have this looked at, a certified pro from YourMechanic can come to your car’s location to inspect the squealing noise and pinpoint the problem.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
Failing Water Pump Pulley: The most common cause of squealing or squeaking from the timing belt cover is the water pump pulley. If the bearings in the pulley are beginning to fail, they will make noise. Eventually, they`ll seize and the water pump will no longer operate, causing your engine to overheat.
Check if the squeaking noise is persistent when you turn on your car, and it feels like it`s coming from the front of your vehicle (under the hood or from the engine bay). If yes, then the squeal you hear is from your serpentine belt or drive belt.
The belt squeals because there is improper tension in the belt drive system. This is usually caused by a worn automatic tensioner, but other causes can include a contaminated belt (oil, belt dressing, etc.) or a belt that is too long or worn out.
Although there are a few causes of a squealing engine, one of the most common is a bad or failing serpentine belt. The serpentine belt – or drive belt, as its also known – plays a vital role in the engine.
High-Pitched Squeal
A loose or worn fan belt, also known as the serpentine belt, is usually the cause. Replacing this belt or belt pulley should eliminate the sound. Consider having the timing belt checked as well.
A high-pitched continuous tone is commonly the result of a nerve or inner ear injury. Treatment is aimed at fixing the underlying abnormality, when it can be identified. Cochlear (inner ear) implants can benefit some patients with severe inner ear nerve damage and hearing loss.
Belt tensioner failure signs
Among the most common signs and causes are: Squeaking noise or unusual noise when starting the engine or during operation when the steering is turned all the way to one side. If the tensioner is loose and not exerting pressure, aux belt can squeak. Accessories failure.
It can squeak, squeal, chirp and clunk, imitating a bad engine-driven accessory or engine bearing. These noises can fool even the most experienced mechanic and lead to an expensive misdiagnosis. Squeals and chirps are definitely the two most common serpentine belt noises and usually result from different problems.
If the whistling sound in your car is most noticeable when you accelerate, the likely culprit is a vacuum leak. The system that controls the air flow between the mass air flow sensor and the engine pushes air through a hose. If the hose comes loose or is damaged it results in a whistling sound as air escapes.
1. Chattering, Squealing, or Chirping Sound. If you hear a chattering, chirping, or squealing noise in the car, it`s likely from a bad belt or from a seized or loose bearing in the pulley.

Car is making a squealing noise! Awful!
ANSWER : Hey there, thanks for writing in about your 2001 Ford Focus. I would suggest you start by adding some belt dressing to the belt, especially since it is new and this is the cheapest and easiest fix for starters. When they are new, they can make that kind of a sound until broken in a bit. If the problem worsens or continues, you may want to have a local expert diagnose the squealing sound in person and advise you on appropriate repairs.

I have a loud squealing noise that is intermittent.
ANSWER : Hi, thanks for writing in. Usually, squealing noises are attributed to a loose belt somewhere on the vehicle, in which case, the serpentine belt could be the issue. However, since you’re experiencing this only during the reverse gear, it could be an issue with low transmission fluid. Honestly, this one is a bit confusing, so you might want to have a professional mechanic take your car on a test drive and complete a belt inspection to determine why your Toyota Camry is making this noise.

Squealing and clicking noise from back part of the car but only when moving forward
ANSWER : Hello, thank you for writing in. The first step is to definitively determine if the noise happens when the vehicle is moving (and it is brake or wheel related), or if the noise happens constantly when the vehicle is running. There may be debris stuck between the rotor and the brake pad, as the space between them while the brakes are off is very small. Wheel weights used for balancing the tires are either clipped or glued to the inside of the wheel, and they may have had issues due to the rain. Locating the noise, and the giving the area a full inspection needs to happen first. If you remove the tire and check the brakes, and there is nothing obviously wrong, then you may want to look into other components in the area. For help with an inspection, contact our service department to schedule an appointment.

squeal wheel noise
ANSWER : That squealing noise typically comes from the wear indicator on disc brake pads. The built-in noise maker indicates that it is time for a brake inspection or brake pad replacement. But when it concerns a safety system like brakes, we won’t assume anything until it has been properly inspected. All four wheels should be removed and the brakes inspected by a qualified technician, such as one from YourMechanic.

my vehicle is making a loud squealing noise, I think it is the power steering pump. it has been leaking fluid for awhile
ANSWER : Hello, thank you for writing in. The power steering pump is a very common place for the system to leak fluid. The pump can mechanically fail, it can crack, and more commonly the gaskets and seal fail. With that being said, it is also one of the components that moves in such a way that it can produce a loud squealing noise. With all of these signs pointing to a failed power steering pump, you should have it replaced. If you want to do some further inspection to confirm, you should attempt to locate the exact location of the leak. For more help with further testing or resolving the issue, contact our service department to schedule an appointment.

Rotors and brakes were replaced only 6 months ago, but have now been making noise again for 3 months.
ANSWER : Hi there. Brake squeaks and squeals are a result of pad vibration, unless it’s a sensor touching letting you know it’s time for brake pad replacement. All brake pads vibrate, whether it’s audible depends on the frequency at which the pad(s) vibrates. This audible vibration may be the result of loose pad hardware or poor fitting replacement brake pads. I recommend having your vehicle’s brakes noise diagnosed and repaired by a certified technician, such as one from YourMechanic.

Rear brake squealing noise goes off when brakes applied.
ANSWER : Hey there. If the noise was not there before you replaced the brake pads on your 2014 Audi A4, you might want to try replacing the caliper clips and using a good quality brake lube anywhere the pads make contact with the caliper, caliper piston, and or bracket. If you need to have this looked at, an expert from YourMechanic can come to your car’s location to diagnose the squealing noise and perform the appropriate repair.
