Almost 60 thousand kilometers. What items do you need to do for major maintenance?

Automobile maintenance projects include the following contents:

Major maintenance refers to the routine maintenance of replacing oil and oil filter, air filter and gasoline filter within the time or mileage specified by the manufacturer.

Time interval for major maintenance:

Large maintenance is based on the existence of small maintenance. Generally, these two kinds of maintenance are carried out alternately. Different car brands have different intervals. Please refer to the manufacturer's suggestion for details.

Supplies under major maintenance:

In addition to changing the oil and oil filter, there are the following two items in car maintenance:

1, air filter

When the engine is working, it will inhale a lot of air. If the air is unfiltered, the dust in it will accelerate the wear of piston group and cylinder. Larger particles entering between the piston and the cylinder will also cause serious "cylinder pulling" phenomenon. The function of the air filter element is to filter out the dust and particles in the air and ensure that enough clean air enters the cylinder.

2. Gasoline filter

The function of gasoline filter is to provide clean fuel for the engine and filter out moisture and impurities in gasoline. So as to optimize the performance of the engine and provide the best protection for the engine. In the process of car maintenance, operators will do other inspections according to the specific conditions of the car, and other maintenance items will be added, such as inspection, cleaning and maintenance of engine-related systems, positioning inspection of tires, inspection of fastening parts and so on.

Automobile maintenance is a preventive work to inspect, clean, supplement, lubricate, adjust or replace some parts of the automobile within a specified period, which is also called automobile maintenance.

Modern automobile maintenance mainly includes the maintenance scope of engine system (engine), gearbox system, air conditioning system, cooling system, fuel system and power steering system.

The purpose of automobile maintenance is to keep the automobile clean and in normal technical condition, eliminate hidden dangers, prevent faults, slow down the deterioration process and prolong its service life.

Extended data

Car maintenance cycle:

1, the replacement of "three filters" has a time limit.

The oil filter must be replaced every time the car is routinely maintained. When driving in non-dusty areas for a long time, the air filter can generally be used for 20,000 kilometers, and it only needs to be cleaned for 7,500 kilometers. The service life of gasoline filter is related to the use of oil. If you have been refueling at a regular gas station and there is no poor oil supply, you can consider replacing it for more than 20,000 kilometers.

In addition, under normal use, the brake pad can travel 30-40 thousand kilometers, and the original battery can be used for 3-4 years. There are many kinds of spark plugs. Ordinary nickel alloy spark plugs can be used for 20,000-30,000 kilometers, platinum spark plugs can be used for 80,000-65,438+10,000 kilometers, and iridium spark plugs can be used for 30,000-40,000 kilometers. Owners can adjust the service life of these components and oil products according to their own vehicle maintenance manuals and actual vehicle conditions.

2. Identification of oil change cycle

Brake oil: Manufacturers generally require about 50,000 km replacement, but in fact there is not much problem. If there is no abnormality in braking, there is no need to replace it. The brake oil is running out, and the handbrake light will light up or flash. It's not too late to change brake oil at this time. Don't change it if the repair shop says to change it.

Engine oil: foreign engine oil is basically replaced only when it reaches 1000 km. Due to poor domestic road conditions, domestic manufacturers generally advance the replacement cycle to 7500 km and 5000 km. But in fact, as long as the oil color is clear and the oil level is not lower than the marked minimum level, it is not necessary to change the oil so frequently under special circumstances.

Steering power-assisted oil: The steering power-assisted oil does not need to be changed frequently, and the dealer also recommends changing it every 6,543,800 kilometers. If you don't change it, there will be no security risks. If there is a lack of steering power oil, there will be abnormal engine noise, and the steering power oil also has a minimum scale, and then change it below the minimum scale.

It's not too late to wash more than 30 thousand kilometers.

The so-called deep cleaning of the engine is actually the cleaning of the internal lubrication system and carbon deposit of the engine. The editor said that because the engine works under high temperature and high pressure for a long time, sludge and carbon deposition will reduce the efficiency of the engine, which is very necessary for old cars with a certain age.

However, most lubricating oils used in automobiles have their own cleaning function, which can ensure that the engine does not produce sludge or a small amount within a certain kilometer. There is absolutely no need to carry out deep engine cleaning when the new car is under warranty, which will cause great waste. Cleaning the lubrication system, air intake, combustion chamber and other items is necessary to maintain the automobile engine, but under the normal use of the vehicle, it usually takes 30,000-50,000 kilometers to consider.

Precautions for automobile maintenance:

First, the maintenance of automobile engines

Car engines should be cleaned at the right time. Because long-term use will form a thick layer of carbon deposit on the engine surface, which will have a great corrosive effect on the rubber parts in the engine.

Second, we should prevent gasoline and water from evaporating.

In summer, the temperature is generally higher. So gasoline and water evaporate more easily than usual. Because the water tank and oil tank should be checked frequently, gasoline and water should be added in time when there is little.

Third, pay attention to hygiene in the car.

Summer is the fastest season for bacteria to multiply, so it is necessary to keep the car clean, especially the car seat cushion, steering wheel cover and car mat.

Fourth, the car wiper should be replaced.

When driving in rainy days, be sure to pay attention to the wiper. The rubber sheet on the wiper will age for a long time. In order to have a better driving sight when driving in rainy days, it is best to replace the wiper once every two years.

Fifth, the car mats should be updated.

Good automobile cooling pad is an important choice for automobile sun protection in hot season. Choose a cool mat that is not too slippery. In order to avoid slipping while driving and causing traffic accidents.

Sixth, the body should also be maintained.

Ultraviolet rays are also very harmful to cars, such as the penetration of car paint. You may notice that after a white car has been exposed to the sun for a long time, the color of the car body will obviously turn pale and yellow. Therefore, waxing and polishing your car in summer can protect your car.
