Car Noise Problems Not many people care so much when their cars make a noise, especially when the car is getting old.

Car users generally believe car noise is normal as long as it’s not stopping on the road.

If your car rattles, squeaks, buzzes, and knocks, then it’s high time you called a car repairer.

What do these noises mean in the car, how dangerous are the causes and how do you get the problems under control?

When the Car Squeaks – The Fan Belt

The most annoying thing to car users when it comes to noise is the loud squeaking that you hear repeatedly from older cars.

Most of the time, the noise starts when you start the car when the engine load is at its highest.

Fortunately, the cause of this car noise can be quickly identified and most times, controlled.

The cause is usually a worn V-belt that no longer engages the wheels it is supposed to drive properly.

As a result of this disengagement, the rubber of the belt rubs against the metal of the wheel, making it squeak loudly.

In most cases, a new belt will solve the problem, but if the problem persists, either a cooling pump or the alternator may be blocked.

In this case, you should park the car immediately and have it checked by a certified mechanic.

Failure to do so can result in engine damage, and for sure, that will cost you a huge budget for a repair.

When Car clicks after Parking

Some cars click after parking. It sounds like little pebbles falling on a metal pan.

That sounds like a surprise at first, perhaps, parked cars shouldn’t make any noise.

The clicking noise when the engine is not running is not a problem.

When the engine warms up, it expands a few millimeters.

 As soon as it cools down again, it contracts again.

Different parts slide on top of each other. This movement causes the clicking sound after parking.

Many drivers also report that the noise lasts particularly longer in winter than in summer.

No wonder, because the colder it is, the further the metal contracts.

The Car whistles on the highway – The turbocharger

If your car whistles at high speeds, it sounds strange at first.

First of all, you should find out whether your car has a turbocharger.

The turbocharger rotates at more than 200,000 revolutions per minute and emits a high-pitched whistle, especially when it is working hard under load.

If you drive a car without a turbocharger, the whistling could come from a loose body panel when the wind blows over it, says Techpally.

Do your Car rattle when Starting?

Some cars rattle when starting. The sound is often compared to pebbles in a tin drum.

Here, too, the catalytic converter could be the problem: protective plates are mounted on the exhaust to protect the expensive catalytic converter from damage.

Sometimes these sheets come loose and wobble when starting up. That can create a rattling noise.

Usually, 5 minutes and an appropriate wrench help, and the problem is solved.

The noise could also come from the gearbox. Then it is actually too late and will lead to a costly repair. 

Not every Car noise can be reliably identified

Unfortunately, with none of these noises, you can really say for sure whether it is a serious problem.

A normal car consists of more than 30,000 parts and each one can make different noises.

If you are not sure whether the noises in your car are a sign of a defect, driving to the workshop or asking a professional car mechanic is the best option.


If you’re a car user, you should be sensitive to the changes in your car sounds.

There are thousands of parts in a car, and tens of it make sounds. 

When the car makes noise that’s strange, try to consult a professional car mechanic to help you out.
