Hello,
There could be many things that may cause noise near the front of the engine pulleys. If they are loose this will cause them to make a bit of noise, which will also cause them to wobble a bit. This can eventually cause the belt to break as well depending on how loose they are. Tensioner pulleys may also make noise if the bearings inside them are wearing out. This may cause a bit of a squeaking noise which will eventually get louder over time. These can also eventually size up also causing the belt to break. I would suggest an expert from YourMechanic come to your location to take a look at your car to determine what may be causing the noise you are describing.

How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
Loud Noise When Accelerating
It could mean the belt`s loose or worn. Or it could mean that one of the belt`s pulleys is starting to fail. Loud rumbling noise when accelerating might suggest there`s a problem with your exhaust system.
One of the common bad idler pulley symptoms is when the engine belts start producing a squealing sound. When the pulley seizes, or the surface is worn-out, then there is a squealing noise as the engine belt rubs against its surface, due to the absence of enough motion from the pulley, a squealing sound is produced.
If any tensioner pulley begins to wear out with time, it`ll create more of a chirping noise. You`ll also hear the chirping noise if the pulley grooves are damaged. This happens over the years due to friction, leading to cracks in the belt.
Grinding or squeaking noise from the belts or tensioner
The most common symptom of a bad or failing drive belt tensioner is noise from the belts or tensioner. If the tensioner is loose the belts may squeak or squeal, especially when the engine is first started.
Usually this type of noise in an indication of a exhaust leak or a vacuum leak due to a broken or disconnected vacuum line. If you also notice that your car is slow to accelerate or is running rough, then it is likely that one of these items is the root cause.
What sound does a bad water pump make? Any high-pitched sound, or an increasingly loud whining sound as you accelerate is usually coming from the car water pump. The same sound happens when a belt is loose, or the bearings are bad. No matter which of these it is, getting your car to the mechanic is a must.
From a manufacturing standpoint, noise can be addressed by applying a nylon covering to the toothed side of the belt, which reduces noise that occurs during meshing. In addition, cutting grooves into the pulley provides a low-pressure path for air to escape as the belt and pulley mesh.
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.
Driving with a bad belt tensioner is unsafe since the tensioner is meant to guarantee ample tension that powers accessories. Wear on the belt tensioner will eventually cause the belt to slip, generate loud noise, and also create an unsafe level of heat along the accessory pulleys.

When a timing belt tensioner fails, it loses tension. As a result, the timing belt becomes loose and the valve timing can be thrown off. This leads to engine performance issues. So if any suspicion arises that the timing belt tensioner has failed, it`s important to check the tensioner and replace it if necessary.

Hello, I have a 2012 jeep compass with engine noise. I inspected it, and it looks to be coming from a pulley. The Crankshaft pulle
ANSWER : There should be no appreciable run-out on the crank pulley and if a physical inspection of the harmonic balancer reveals damage such as a broken, cracked or separated rubber bond, the balancer should be replaced. If you do have a failed balancer, don’t operate the engine because the imbalance and/or torsional forces on the crankshaft can cause damage to the crankshaft and main bearings. You can obtain an inspection/repair quote, and schedule the repair as you like, by simply visiting YourMechanic’s harmonic balancer repair service page and click on "Get a Quote". If you request this service, the responding certified mechanic will first inspect what you have and, if indicated, implement the required repairs and answer any questions that you might have. With regard to the ticking noise, that is almost undoubtedly valve train noise. A certain, minimal level of noise can occur on particular makes and models. Whoever performs the balancer inspection and repair, if required can evaluate that noise up close and let you know if it is normal or not. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.
Turned on back winow heater and engine made a noise …when lights are turned on engine makes a noise like it can’t take load ….
ANSWER : Hi there. It appears you have more than one problem with your vehicle. The noise coming from engine area with a load on the electrical system, may be a bad diode in the alternator. Continuing to drive the vehicle with a bad alternator diode, may leave you with a dead battery. The hot air coming from the vents sounds like blend door actuator(s) problems. I recommend the concerns your vehicle has, it be inspected by a certified technician like one from YourMechanic to pinpoint the noise and help you fix it accordingly.

There could be many things that may cause noise near the front of the engine pulleys. If they are loose this will cause them to make a bit of noise, which will also cause them to wobble a bit. This can eventually cause the belt to break as well depending on how loose they are. Tensioner pulleys may also make noise if the bearings inside them are wearing out. This may cause a bit of a squeaking noise which will eventually get louder over time. These can also eventually size up also causing the belt to break.

My Toyota is making a noise when I start the engine and bogs the engine down for a second then goes away.
ANSWER : Hi there. A binding accessory could be causing your concern. Simply remove the drive belt and recheck. If the problem goes away, this eliminates the fear that there could be something goin on with the engine or transmission internally. It sounds like this could be the water pump. If the water pump is binding or leaking, it can cause the belt to slip and make it seem like the engine gets bogged down. Usually a visual inspection quickly uncovers the leak. However a properly executed pressure test is the best way to uncover leaks, both current and potential. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car is making a noise inspection.
Car making popping noise when braking.
ANSWER : After seeing the video, you will need to have the lower ball joints and bushings checked to see if one or all need to be replaced. You should also have the exhaust checked to see why the engine is so loud. A professional mechanic, such as one from YourMechanic, will be able to thoroughly conduct tests to diagnose your vehicle’s popping noise and make the appropriate repairs.
Car makes grinding noise – 1996 Chevrolet Corsica
ANSWER : Hey there, thanks for writing in. I would have a professional mechanic check out the constant velocity joints on your vehicle. One or more of them may be worn enough to cause the noises you describe. S/he can diagnose and replace any failed CV joints.
A large clunking noise is coming from the front left of my car anytime I start my car, and anytime I go over a pothole/speedbump
ANSWER : Hi, thanks for writing in. If simply starting your car causes a clunk, then you may have another damaged motor or transmission mount (there are 4 total). You should replace all 4 mounts. When one mount fails, it allows excess motion of the engine/transmission, damaging the other mounts as well. It is false economy, generally speaking, with the age and mileage of your Honda, to do them one at a time. If you would like help with these replacements, consider having an expert automotive technician from YourMechanic come to your home or office to perform the engine mount replacements for you.
