5 Causes and How to Overcome a Buzzing Sound in a Car

The humming sound experienced by cars generally occurs because the vehicle is aging. The humming sound in the car that can be felt in the cabin happens because the parts of an old car tend to be damaged and worn out, especially if the owner is lazy to maintain the vehicle. Here are the causes and how to overcome it!

Causes of Humming Sound in Cars

Here are the causes of noisy sounds in vehicle engines that need to be known.

1. Damaged power steering pump

A damaged power steering pump can cause a humming sound in the engine, usually occurring in cars that use hydraulic power steering. This is because there are several components attached to the engine to reduce the driver's load.

2. Worn pulley bearing

When the engine pulley bearing wears out, it can affect driving comfort because this component is quite vital for the vehicle. The engine has many belt wraps with pulleys, such as the engine pulley, alternator, and idler. If one of them is damaged, it needs to be replaced immediately.

3. AC Compressor Damage

A damaged AC compressor can be the cause of a humming sound in the car. This occurs when the metal of the AC compressor wears out, especially when the AC freon is clogged, which can worsen the condition.

4. Damaged coupling joint

Four-wheeled vehicles have a coupling joint to transmit rotation to the wheels. This component is prone to wear, resulting in a humming sound.

5. Incorrectly installed or damaged timing belt

An old timing belt can also cause a rather disturbing humming sound. In addition to an old timing belt, improper installation of this component can also cause the noisy sound to be heard.

How to Overcome Humming Sounds in Cars

After knowing the causes, here are ways to overcome noisy sounds in four-wheeled vehicles.

1. Perform regular power steering checks

Owners need to perform regular checks, especially on the power steering components. This is because the humming sound generally comes from this component and can be addressed if checked beforehand.

2. Repair the bearing

The noisy sound entering the vehicle cabin certainly reduces the comfort level of the driver and passengers. Therefore, repair the bearing or wheel neck if this component is damaged.

3. Check the AC compressor

Try to check the AC compressor section by turning it off while the engine is running. When the AC is turned off, the humming sound will gradually disappear. If there is indeed a problem, take the vehicle to the nearest car AC workshop immediately.

4. Regularly change the lubricant

Additionally, to address the humming sound, regularly change the lubricant or oil to avoid problems in the drive axle system. Make sure to change the axle oil every 40,000 km.

5. Regularly check the timing belt

Improper installation of this component can cause a humming sound, as can installing this part too tightly, which can cause slipping. Therefore, perform regular checks, especially before the vehicle is used.

Tips for Maintaining Car Engines

Here are ways to maintain the engine of a four-wheeled vehicle to keep it durable.

1. Warm up the engine every day

It is advisable to regularly warm up the car every day, even if only for a few minutes each morning. Engines that are regularly warmed up generally rarely experience problems, distribute oil evenly throughout the engine, and their performance will remain optimal.

2. Regularly use the car

Additionally, try to regularly use the vehicle, even if only occasionally within a week. This is beneficial to see if there are any changes in the engine's condition.

3. Check the oil

When the vehicle has traveled 10,000 km, it is advisable to change the engine oil immediately. Checking the oil condition is very easy, as the oil indicator is usually visible on the dashboard.

That is the cause and easy ways to overcome the humming sound in the car that can be quite disturbing as it can be heard in the cabin.
