There are two main aspects of car maintenance knowledge.，One is the mandatory maintenance provided by the maintenance station。on the other hand， The owner conducts some daily maintenance based on their common sense of car maintenance.。The understanding of automotive maintenance is directly related to the service life of the car and the safety of drivers and passengers.。
1。 Specific maintenance project introduction
1。 Body paint maintenance
If the body is obviously scratched，Spray external。The role of paint is not only beautiful，It is more important to have rust resistance。Summer is a rainy water in the rainy season，Summer sunshine causes surface corrosion and oxidation of paint。Please choose to clean， polishing， Wax Seal or coating treatment according to the actual situation of the body。
2。 Car tire maintenance
Because the air in the summer high temperature tire is usually not too strong。Autumn is different due to low temperatures，Tires need to be filled with air pressure，Reach the specified range。Simultaneously，At the same time, check if the tire is obviously injured.， Scratch Wait in autumn and winter season Rubber becomes harder and crisp。The coefficient of friction will not only reduce，Leakage and piercing tires are also easier。
3。 Cabin check
Oil Steering， Brake oil and antifreeze detection。
4。 Brake system detection
Pay attention to whether the brake fluid is sufficient，Whether the quality is deteriorated，Need to add or replace it in time，Simultaneously，Pay attention to whether the brakes are weakened or stall，The position of the pedaling force and wheel lock point during the braking process，If necessary， Clean the pipe part of the entire brake system。
5， Ignition system ignition system maintenance
This is related to whether the vehicle can start， Plug position should be carefully checked，See if it rust。Once rust，Professional cleaners must be used。
6。 Maintenance charging system
Check if the generator belt aging or rupture after the rainy season or high temperature weather is very important。If you don't happen above，Remember to see the tightness of the belt。Belt is too loose, can cause screams of the belt，Breakfast belt； Belt is too tight, which will also cause eccentric wear of generator bearings.。
7。 Maintenance of autumn chassis
The focus is rust and tire examination。on the one hand，After the rainy season or high temperature，The metal material of the chassis is exposed to the sun.，Easy to rust hinder driving safety。therefore，The chassis must be removed，And check if the chassis has scratches and screws to fall off。
8。 Replace antifreeze
Autumn weather turns cold，Cold air，It may affect the normal operation of the car cooling system。
9。 Position of intake or intake grill， Electronic fan and many more
Check debris。You can use compressed air to blow away dust，The water gun can be used to clean the parts from the internal to external cleansing parts.。
10。 Battery maintenance battery electrode connection
It is also easy to have problems.，Especially in the wet season, you should pay attention to timely maintenance.。
11。 Maintain hot air pipes and fans
Autumn weather is cool，White cream occurs when the temperature is low，In this season, please pay special attention to whether the wind under the windshield defrost air is normal.。Is there enough calories? If you have something to solve in time，Apart from this，I will cause unsafe factors to your driving。
12 Air conditioning repair
There are many rain vehicles in the summer, often walk on some water-related roads.，The lower part of the air conditioner condenser is inevitably contaminated by sand。over time，Deposited a lot of silt and dust，Seriously affecting the service life of air conditioners，therefore，It is very important in this season that checks and maintains the health of air conditioners.。In addition， Vehicle water tanks are also easily contaminated by sand。Always pay attention to this，Once the vehicle tank is found to have a precipitate，Should be cleaned immediately。
13 Car interior cleaning
After a rainy summer，Carpets and floor gums and other corners of breeding a lot of bacteria。Autumn weather turns cold，Car window is not open，The air in the carriage began to become cloudy，Odor and bacteria will endanger human health。So autumn is coming, you should immediately disinfect and clean your car.。
two， Maintenance cycle analysis
1。 Deepen car lubrication system repair
The main function of the lubrication system is to effectively lubricate the various parts of the automobile engine.。Prevent excessive wear。under normal circumstances，BMW needs every10Clean and maintenance，000Kilometer。When there is too much engine noise，Weak acceleration，When the water temperature is too high It needs cleaning and maintenance。Clean the soil and other sediments in the engine，Avoid oxidation and thickening of oil at high temperatures，Reduce the wear of engine components，Extend the life of the engine，Improve engine power。
2。 Cleaning and maintenance of automotive fuel systems
under normal circumstances，The car needs each10000km-15000kmClean and maintenance。Or when you feel the engine，Histurous and poor acceleration，Black smoke，If the oil is insufficient or waste oil，Please clean and maintain once。Clear colloids and carbon deposited inside the system，Prevent hazardous corrosion，Avoid and prevent the seal and the leakage of the water tank，Replace the old coolant。
3。 Cleaning and maintenance of automobile cooling systems
in general，Winter and summer，Clean and maintenance car once。During normal driving，each6Until8Cleaning and maintenance of months，Or cleans and maintain it when the water temperature is too high.， Leak， Or the pot is boiling。Clear traces and scale caused by overheating engine，Prevent hazardous corrosion，Avoid and prevent the seal and the leakage of the water tank，Replace the old coolant。
4。 Cleaning and maintenance of automotive gearboxes
BMW gearbox oil，however， Still suggestion60Replacement，000-100，000Kilometer。
5， Cleaning and maintenance of automotive power steering systems
This car needs each40Secondary maintenance，000km-45，Drive000易彤破壁机售后电话Kilometer。Otherwise, the system will leak when turning to difficulties.，After replacing the power steering attachment，You must also clean and maintain once。Clear harmful sludge and paint film in the system，Clear low temperature steering difficulties，Stop and prevent power steering liquid leakage，Clear steering noise，Replace the old brake steering liquid。
6。 Cleaning and maintenance of automotive brake systems
Every50Clean and maintenance，000Kilometer，OtherwiseABSThe reaction is premature，If it is too slow，Please clean and maintain once。Remove harmful sludge paint film in the system，Eliminate the risk of failure at ultra-high temperature or ultra-low temperature，Effectively prevent brake fluid deterioration and expire，Replace the old brake fluid。
Precaution：
1。 BMWDaily maintenance should 易彤破壁机官网 be performed according to the maintenance indicator on the dashboard。The specification of the display depends on the equipment of the car.。
2。The less the green area of the maintenance indicator light，Your car is close to the next routine maintenance date.。
3。The yellow area of the maintenance indicator will beOILSERVICE（Replacement service）orINSPECTION（Maintenance check）Lit together together，Indicates that the maintenance date has arrived，Please reach a maintenance service agreement with BMW maintenance department。
4。The red area of the maintenance indicator is on， It indicates that the specified maintenance date has expired。Few users with car-Years less10，000kmThe most late should also be replaced once every two years.。Since the load engine oil will be aging over time。
