4 filters that need to be cleaned and replaced periodically in cars

1. Engine air filter

Air filters have the role of filtering dust and dirt in the air. After a period of use, dust and moisture stick to the filter membrane, filling the filter's air vents...If not cleaned or replaced, it will hinder the amount of air entering the engine, causing an incorrect air-fuel ratio, reducing power, overheating the engine, and causing carbon deposits in the combustion chamber.

According to the manufacturers' recommendations, car users should pay attention to periodically cleaning the engine air filter system after the car has run 5,000 km; and replace the air filter after 20,000 km. For older cars, often used in dusty environments, the air filter should be cleaned after 3,000 - 4,000 km; and replaced after 15,000 km.

The air filter system should be checked regularly. If the filter is found to be torn or damp, it should be replaced with a new filter.

2.Filterfuel

Fuel filter (also known as gasoline filter, diesel filter) helps remove dirt and rust in gasoline and oil pumped into the vehicle; creating a clean fuel source before entering the engine combustion chamber.

During use, if dirt or damage accumulates, the filter will become clogged, blocking the fuel flow to the carburetor or injector, causing the engine to be difficult to start, jerking, and unstable vehicle operation. Users should periodically check and clean the fuel filter. After about 40,000 km of use, the fuel filter should be replaced.

3. Air conditioning system filter

The air conditioning system filter (cabin air filter) has the role of filtering dust and cleaning the air before it goes through the air conditioning system into the car's interior.

During use, dust and dirt on the filters will reduce the air flow into the air conditioner in the outside air intake mode, affecting the cooling time of the interior compartment. In addition, exposure to the environment makes the air conditioner filter moldy, creating an unpleasant smell...

With this part, car users should pay attention to check and clean after using the car for about 5,000 km; replace after 20,000 km. During use, if the air passing through the air conditioner decreases, the fan system makes noise... you should check and replace the air conditioner filter.

4. Engine oil filter

Often called "oil filter cup", it plays an important role in filtering out dirt and impurities in engine oil, ensuring lubrication of internal engine parts.

The engine oil filter system cannot be cleaned but must be replaced periodically after a period of use. Users should pay attention to checking the engine oil level and replacing the oil filter after 10,000 km. In order not to forget this part, some experienced people often replace the "oil filter cup" after 2 engine oil changes.

On some car models, the “oil filter cup” is often located under the engine, so when replacing it, pay attention to the installation to avoid leakage; carefully study the engine's technical information to choose the right oil filter.
