How often should the car be serviced? What s in it?

When the new car has traveled 1,000 kilometers, the engine oil, oil filter and transmission oil need to be replaced, because all the parts of the new car are completely new combinations, so they cannot be completely sealed smoothly when they come into contact with each other, for example, the friction between the piston and the piston rings, the gears in the gearbox, etc., will produce small residues after friction, and these residues will flow into the oil and transmission oil that lubricate the parts.

Spark plugs are replaced about once every 20,000 kilometers, and some car manufacturers replace them once every 30,000 kilometers.

The maintenance interval depends on the grade and grade of the oil used. The expiration date of different grades of engine oil is also very different. For example:

The expiration date of mineral oil is 5000 km or three months; The shelf life of semi-synthetic motor oil is 7500 km or half a year; The shelf life of fully synthetic motor oil is 10,000 km or one year. It can also be subject to the manufacturer's recommendation.

1.Generally, the oil is changed once every 3000-5000 kilometers. (Based on the frequency of recent departures) 2The antifreeze is not affected by the season, and it does not need to be replaced in a short time (it must be replaced once every 2 years, and the waterway should be cleaned by the way).

3.Generally, change the oil at the same time and replace the three filters once? (Otherwise, it is meaningless to only change the oil filter without changing the oil and changing the oil filter).

4.It is best to change the brake fluid once a year.

5.Is it best to change the transmission fluid every 2 years after the first change on the first anniversary of buying a new car?

6.Generally do a four-wheel alignment at about 10,000 kilometers? (At this time, the front speed, the wear of the middle sleeve will be caused.)"Fetal eating")

7.It is best to wax the car twice regularly in spring and autumn.

Car maintenance has always been the most interesting topic for private car owners, when is the best time to maintain your car? What is the best thing to replace when maintaining? And so on and so forth.

Car maintenance can be divided into two categories: minor maintenance and major maintenance in the industry. Minor maintenance refers to the operation of changing the oil and oil filter after the required mileage has been reached.

Now most of the models in the world are required to be maintained once every 5,000 kilometers. However, in my opinion, this is mainly based on the quality and type of oil. It is best to have a small maintenance at around 5,000 kilometers for a car with semi-synthetic oil, while a car with a full synthetic oil is best to have a minor maintenance at around 10,000 kilometers.

Car owners can distinguish what mileage of their car needs to be maintained according to the type of engine oil they add.

Major maintenance is based on the replacement of gasoline filters, air conditioning filters, air filters, spark plugs, antifreeze, transmission fluid, and other parts in addition to minor maintenance. Let's introduce them one by one: the gasoline filter is a component that filters gasoline impurities.

Under normal circumstances, as long as no inferior gasoline is added, then the gasoline filter can be replaced after every 20,000 kilometers;

The air conditioning filter and air filter are both parts that filter external impurities, and there is no fixed replacement time, which must be decided according to the road conditions that the owner often drives. Car owners who often drive on dirt roads in the city or countryside need to be replaced more frequently, generally 5000 kilometers need to be replaced. In the suburbs, car owners who drive a lot can change it once at 8,000 kilometers;

Spark plugs, antifreeze and transmission fluid are among the components that are less frequently replaced. Under normal circumstances, an average of 50,000-60,000 kilometers can be replaced. The specific parameters should be made after being checked by the staff of the auto repair shop.

The above is my summary of car maintenance, I hope it can be helpful to you.

<><1.Semi-annual maintenance content.

Clean the outer surface of the engine, and pay attention to the waterproof treatment of the electrical part when cleaning. If the electrical part has high requirements for waterproofing, it is necessary to avoid using a high-pressure and high-temperature water gun to clean the engine, and you can use a brush dipped in cleaning agent to clean the surface of the engine. The distributor should use a clean rag to clean the dirt inside the distributor cover, remove the dirt at the distributor contacts, eliminate the traces of contact ablation, check the gap between the high-speed contacts or the magnetic pole gap of the electronic ignition system, and lubricate all the lubrication points of the distributor.

Check the coolant, replenish the coolant, clean the surface of the tank.

2.Annual maintenance content.

Check the ignition timing and adjust the ignition timing of the car engine. It is best to check and adjust the fuel supply timing of the diesel engine at the repair shop. Valve clearanceFor engines with normal valves, check high-speed valve clearance.

Clean, lubricate and clean the engine compartment covers, doors and luggage compartment hinge mechanisms, and readjust and lubricate the said mechanisms.

3.Maintain the content every two years.

AntifreezeThe lifespan of antifreeze is generally two years. At that time, the antifreeze should be replaced during the annual maintenance and the cooling system should be thoroughly cleaned. Braking systemDue to the hygroscopic nature of the braking system, the brake fluid is changed every two years.

As for how often to maintain the car, some cars require 5,000 kilometers for maintenance, some cars require 7,500 kilometers for maintenance, and even some cars require 10,000 kilometers for maintenance, depending on the specific brand. However, there are also many 4S people who deliberately shorten the maintenance time in order to make a profit.

Minor maintenance is carried out every 5,000 km or half a year. The main items of maintenance are: oil change, machine filtration, cleaning of air filters.

There is also to check the level of antifreeze and the corresponding freezing point, as well as the aging degree of the battery, whether the headlights and small lights are turned on normally, the use status of the horn, and then check whether the brake pads are seriously worn and whether there is oil leakage.

The general recommended time for major maintenance is 20,000 kilometers or once every two years! There are more than small maintenance items: the fuel filter must be replaced, and then the air air filter. There are many other check-up items.

The maintenance and replacement cycle of other important parts of the car is: spark plug 20,000 km, wiper once a year, brake fluid and coolant once every two years, tires once 5-80,000 km, brake pads once 6-80,000 km, battery once every 3-4 years, fuel filter once 100,000 km.
