Introduction When should the car battery be replaced? Car batteries are typically replaced every 2 to 4 years. Theoretically, the lifespan of a car battery is usually around 2 to 3 years, if used and maintained properly.

When should the car battery be replaced?

Car batteries are typically replaced every 2 to 4 years.

Theoretically speaking, the lifespan of a car battery is generally around 2 to 3 years. If used and maintained correctly, it can be used for 4 years without any problems. It can also break prematurely within a few months if not used and maintained properly. It is therefore very important to use the car battery correctly.

Generally speaking, the battery used in the car should be replaced every two years. If properly maintained, it can be used for four years. The battery plays an important role in the use of the car. If it cannot supply power normally, the motor will have problems or stall. It should be checked frequently during daily driving. It should be checked once a week in summer and every two months. in winter.

Battery maintenance

Note in daily life:

1. Avoid parking the car in an open-air parking lot for a long time if it is parked. for a long time it must be removed. Remove the battery to prevent the battery from freezing damage.

2. The car engine is not easy to start in winter. The car starting time should not exceed 5 seconds each time, and the interval between restarts should not be less than 15 seconds. If it still does not light up after several starts, the cause should be looked for in other aspects such as the circuit, ignition coil or oil circuit. Avoid starting multiple times without interruption, as this may cause the battery to drain due to over-discharge.

3. The car battery should be charged frequently. If the battery is not used for a long time, it wille will discharge slowly until it is discarded. Therefore, the car must be started from time to time. to charge the battery.

1. Oil Maintenance

If the car engine is the heart of the car, then engine oil is the blood of the car. Generally, the maintenance mileage of a car is 5,000 kilometers or six months, whichever comes first (such as Hyundai, Toyota). Some vehicles have a service mileage of 10,000 kilometers or one year, whichever comes first (such as BMW, Mercedes-Benz). ). Some vehicles have a service mileage of 15,000. It is best to refer to the service manual for the specific service mileage and years in kilometers (like the signs).

I believe most car owners have experience doing maintenance in advance. I wonder if you were deceived by the service staff of store 4S. You must perform maintenance in advance before the maintenance mileage is reached. reached. In fact, it's completely unnecessary. The selection of maintenance oil is mainly based on the requirements of the engine and the operating environment. There is no need to blindly search for high-quality engine oil. Just choose the right one, not the most expensive one. If the selected engine oil grade does not match, it will lead to serious consequences such as poor lubrication and oil burning.

2. Brake Fluid Maintenance

The maintenance cycle for brake fluid (brake oil) is 2 years or 40,000 kilometers. Brake fluid is the basis of the braking system. Therefore, its requirements are relatively high. Nowadays, cars mainly use DOT4 grade brake fluid. Different grades of brake fluid cannot be mixed.

Why do you need to change the brake fluid? Because water in the air enters the brake fluid and reduces the boiling point of the brake fluid, resulting in poor braking effect or no braking at all. Remember to change the brake fluid according to the service manual to protect yourself and others.

3. Maintenance of the water glass

The function of the water glass is to clean the windshield. Glass water is divided into winter glass water and summer glass water. There are many types of glass water on the market, so how to choose a suitable glass water?

The requirements for suitable glass water in summer are not so high. The main function of water glass in summer is to. remove the shellac. When you fill the glass with water, you can add water appropriately. In winter, glass water with high freezing point should be selectionborn depending on the local temperature.

4. Spark Plug Maintenance

The function of the spark plug is to ignite the mixture. The service interval for spark plugs is approximately 50,000 kilometers. Spark plugs are essential for engine combustion. Why should we replace the spark plug? As the engine runs, the spark plug constantly wears out. Each ignition will wear out the electrode. Over time, the ignition energy of the spark plug will be reduced, resulting in poor engine acceleration. , misfires and other phenomena. Spark plugs need to be replaced on time, and you cannot be greedy to drive tens of thousands of extra kilometers, as this can lead to unexpected consequences. Especially for direct injection engines, the requirements for spark plugs are relatively high, requiring ahigh ignition energy, prone to wear, and the replacement cycle is shortened (about 30,000 kilometers).

5. Maintenance of wiper blades

The function of wiper blades is to clean the windshield. It is recommended to replace the wiper blades depending on usage conditions. Generally, they can be replaced when the wiper effect is poor, the wiper blades are scratched or the wiper noise is loud.

6. Maintaining the air conditioning filter

The function of the air conditioning filter is to purify the air entering the car. The replacement cycle of automobile air conditioning filters is generally around 20,000 kilometers, but the replacement cycle may be shortened due to environmental problems, such as in Beijing where smog is severe. The air conditioning filter element is directly related to the air quality in the car. What arethe symptoms of a dirty air conditioning filter element? When the air conditioner is turned on, you will feel that the air volume is obviously small, and there is an obvious smell in the blowing wind. If you encounter this situation, replace the filter element directly.

7. Fuel Filter Maintenance

The function of the fuel filter (gasoline filter element) is to filter fuel. There are two types of fuel filters: integrated and external. Generally, the maintenance mileage of external gasoline filter elements is about 30,000 kilometers; the maintenance mileage of internal gasoline filter elements is about 50,000 kilometers. At present, the gasoline in some domestic gas stations does not meet standards, which directly leads to a shortening of the life of gasoline filters. Clogged fuel filter element prevents engine from starting properlyt the engine accelerates slowly.

8. Air Filter Maintenance

The function of the air filter is to purify the air entering the engine and prevent dust, sand and various impurities from entering and burning in the engine. Replacing the air filter elements usually occurs around 20,000 kilometers (slightly different depending on the model), which is specifically related to the driving environment of the car. A dirty, clogged air filter can lead to wasted fuel, exceeding emissions standards, engine alarms and even cylinder pulls. Removing and installing the air filter element is very simple, and you can usually clean it yourself, especially in spring when the sky is full of poplar catkins.

9.Maintenance of brake pads

The maintenance of brake pads (brake pads) is judged based on their use. When a replacementt is necessary, there will be a replacement prompt on the dashboard. In big cities like Beijing and Shanghai, vehicles are crowded and brakes are frequently used, which will shorten the brake pad replacement cycle. Generally, the loss of the front film is greater than that of the rear film. The thickness of brake pads is generally less than 3mm and it is recommended to replace them. Car owners can directly check whether they need to be replaced to avoid making a mistake.

10. Antifreeze Maintenance

The function of antifreeze is to prevent freezing and circulate heat. The antifreeze replacement cycle is 2 years or 50,000 kilometers, and some cars require no replacement for life. The quality of antifreeze is linked to engine performance, fuel consumption and the life of each component. It is recommended to replace itaccording to the manufacturer's standards.

I hope it will be useful to you and I hope you will adopt it!
