How does Vehicle Maintenance stipulate deadlines for minor and major car maintenance?

Introduction How does Vehicle Maintenance stipulate deadlines for minor and major car maintenance? Routine major vehicle maintenance should be performed every 3 to 5 kilometers. Minor maintenance depends on the engine oil used in the different engines of the vehicle.

How does Vehicle Maintenance stipulate deadlines for minor and major car maintenance?

Routine major vehicle maintenance should be performed every 3 to 5 kilometers. Minor maintenance is determined based on the engine oil used. Different engine oil service intervals are different. For example, my car uses GT engine oil and grade. Base oil 4 PAO. , minor maintenance is to replace it every 15,000 kilometers, which is 3 times longer than the semi-synthetic oil I used before, and the breakdown period is also longer than what I had used to traveling 2,000 or 3,000 kilometers. and the car would not seem dull, but now it has covered 10,000 kilometers, the power performance of the car is very good, and it is very comfortable to drive. ∞

How do you typically maintain a car?

How often should you perform major and minor maintenance on your car? The interviewst generally carried out every three years or every 60,000 kilometers. It is best to complete all items in the service manual. Minor maintenance is usually performed once every six months or approximately 7,500 kilometers. There are few items, mainly replacing the oil filter.

“Minor Maintenance” generally refers to items of routine maintenance to ensure vehicle performance, primarily including oil and oil filter replacement and routine inspections. Car engines need lubrication and engine oil plays a role in lubricating, cleaning, sealing and cooling. However, as the car is driven, the base oil and additives contained in the engine oil deteriorate and become invalid. Therefore, in order to protect the engine, engine oil should be replaced regularly.

The “major maintenance” is relative to small maintenance. In addition to changing the oil, a third filter and spark plugs also need to be replaced. The three filters refer to the air filter, oil filter and fuel filter. The filter is used to filter impurities, and the third filter plays the role of filtering dust in the air, sludge in oil, carbon deposits and impurities in gasoline. Additionally, after long-distance driving, key components such as brake fluid, antifreeze, transmission oil, and timing belt need to be replaced.

Major maintenance of the car corresponds to minor maintenance: the major maintenance interval of the car is long, the mileage is long, and there are many items; minor maintenance interval is short, mileage is long; in short, and there are few articles. Major maintenance is generally carried out every three years or every 60,000 kilometers.res. It is best to complete all items in the service manual, such as: inspection and replacement of five oils and three waters, replacement of generator and fan belt, replacement of spark plugs . , etc. , it is a very good opportunity for us to understand the condition of the car; minor maintenance is usually carried out once every six months, or approximately 7,500 kilometers. There are few items, mainly replacing the oil filter.

Most major automotive services are performed every 20,000 to 30,000 miles or every two years. Different car brands, different driving environments and different driving habits are basically related to the time and frequency of major car maintenance. It is necessary for friends to reasonably carry out major maintenance on their car through the use of the car.

When a carIt has been driven for a number of years and kilometers, it needs major maintenance. The maintenance method of major maintenance refers to the addition of other items on the basis of minor maintenance, that is, in addition to changing the engine oil and the item of the oil filter, it is also necessary to check and replace the antifreeze, transmission oil, brakes of the vehicle. oil and steering oil.

1. Oil Maintenance

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

I believe most car owners have experience doing maintenance in advance. I wonder if you were deceived by the service staff of the 4S store. 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 brake fluid (brake oil) maintenance cycle 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 notso 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 a high freezing point should be selected according to 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 in time and you cannot be greedy fortravel tens of thousands of extra miles, as this can lead to unintended consequences. Direct injection engines, in particular, have relatively high requirements for spark plugs, which require significant ignition energy, are prone to wear and have a shorter replacement cycle (around 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 not good, 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 filter elements isusually about 20,000 kilometers, but due to environmental problems, the replacement cycle may be It may be shortened, such as in Beijing where smog is severe. The air conditioning filter element is directly related to the air quality in the car. What are the 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 service mileage of the internal gasoline filter elements is approximately 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. The clogged fuel filter element prevents the engine from starting properly and the engine accelerates poorly.

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. Removal and installation of the air filter element is very simple, et you can usually clean it yourself, especially in spring when the sky is full of poplar catkins.

9. Brake pad maintenance

The maintenance of brake pads (brake pads) is judged by their use. When replacement is necessary, there will be a replacement prompt on the dashboard. In big cities like Beijing and Shanghai, vehicles are crowded and brakes are used frequently, 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 cycle of reAntifreeze replacement is 2 years or 50,000 miles, and some cars require no replacement for life. The quality of antifreeze is linked to engine performance, fuel consumption and the lifespan of the various components. It is recommended to replace it according to the manufacturer's standards.
