6 car parts to check immediately when there is a strange noise

(Baonghean.vn) - If the noise in the car does not cause serious consequences, the driver often ignores it. But in reality, when the noise appears, it is a sign that the car has a problem;Therefore, you should pay attention when operating to take the vehicle for timely repair.

1.The engine makes a clicking noise.

Engines make rattling noises when they have not been serviced regularly, the engine oil is low or the oil pressure is not up to the manufacturer's recommended levels.

The clicking sound could also be caused by valve train knock, low oil pressure from the crankcase, pump failure, or hydraulic problem.

When the car engine overheats and makes a strange screeching sound under the hood, the car engine may be under too much heat load, or there is a possibility that the coolant has leaked out.

Therefore, when you hear the noise your car needs to be checked and maintained to ensure the engine can operate continuously.

2. Belt

The sound of the belt is easily recognized by the sound of rubber rubbing against metal surfaces. If the sound appears right when the engine is first started and disappears after a few minutes, the cause is due to a loose or stiff belt, it is time to replace it.

If the noise persists even when the engine is hot, it is time to replace the timing belt. Due to the dependence on working conditions and environment, many manufacturers only recommend that vehicle users regularly check the timing belt during each periodic maintenance, but do not recommend the time of use.

3. Front tire

Tires are the part of a vehicle that comes into contact with the road surface and greatly affect the handling of the vehicle; the wheel has more moving parts than the steering shaft.

One of the common sounds that comes out is a screeching, growling sound when you brake. Therefore, you should pay attention to the grinding sound from the front wheel when braking. The cause of the noise is due to worn brake pads, so check or replace the brake pads as soon as possible to ensure safety.

4. Exhaust noise when accelerating

When you detect a strange sound coming from the exhaust system, you should not ignore it. Because it is very possible that the exhaust system is leaking, dangerous exhaust gases are entering the car.

If the exhaust system leaks at the right critical location, carbon monoxide will build up inside the car. And when you close all the windows, this inadvertently fills the interior of the car with toxic gas.

What you need to do is to identify where the noise is coming from. Park your car on a level surface with the handbrake on, get out of the car, lie down next to it, listen to the engine and identify where the noise is coming from.

5. Noise from the steering column assembly

When the steering wheel makes strange noises, it usually sounds like a "click"; the noise increases over time, as the vehicle is operated.

As experienced drivers, they can easily spot problems with the system: worn or damaged synchronizer joints, faulty bearings inside the steering column, low power steering fluid level.

The power steering rack also tends to make a squealing noise, which is a sign of a slipping drive belt.

Do not ignore the noise coming from this part, if serious it can threaten the lives of people in the car.

6. Squealing sound from the car brakes.

Normally the brake system works relatively smoothly; if there is a screeching sound, the brake pads may be worn and need to be replaced promptly to ensure the most stable operation of the vehicle, increasing safety for the user.

In addition, the driver can observe the brake pads as long-term use will lead to the brake pads being worn to the point of almost drying out the grooves or there are no grooves in the brake pads as originally designed, or the brake pads are only at a level of less than 3mm, the wear sensor reminds... then the brake pads need to be replaced.
