Generally speaking, the life cycle of a car is divided into:The running-in period, the peak period, the maturity period,Decline period, dangerous period Five stages.

The "physical condition" of cars in different periods is very different，In these five stages, The focus of car maintenance and repair should be different,If you want to keep your car in good condition，Need to know the maintenance precautions in different cycles。

The running-in period generally refers to the contact between vehicle mechanical parts、Friction、Occlusion period of about one year，This period is equivalent to human youth，This period，Motor oil is particularly important，Because oil changes are required to coordinate the running-in of major parts such as the vehicle engine，For this reason, the quality of the engine oil used can be appropriately improved，Replace engine oil and oil filter in time，Check the performance of the braking system more often、Quality and quantity of brake fluid, steering system and booster oil, etc.。

Golden period: within 3 years after purchasing the car

Many mainstream models have fulfilled the three-year and 100,000-kilometer warranty commitment，And most of the special parts of the vehicle also have a 3-year warranty。Put it this way，Three years is a difficult time，After passing，The cost of maintenance will start to rise，So the period within 3 years is also called the golden period of the vehicle。

Although the vehicle will not be as brand new and bright as a pure new car after one year，But still maintains good performance and running condition。Although some wearing and consumable parts need to be replaced at certain intervals，But it does not affect the overall excellent use effect of the vehicle。

For a car that has a three-year warranty，The maintenance to be done is in the following aspects:

1.Carry out regular maintenance items first，Such as changing oil and filter, etc.。

2.Full vehicle seabet appinspection: focus on items related to driving safety。

① Check the working status of wipers, lights and reversing radar;

②Check the engine room items;

③Check the condition of the vehicle chassis;

④Full vehicle tire inspection;

⑤Inspection of brake system components.

Maturity period

Car used for 3-5 years,The vehicle has entered the maturity stage。The mature stage means that the state of the vehicle has entered its peak stage,After this stage, it will start to gradually decline。

Some models begin to appear: aging parts、Oil leakage、Minor problems such as water leakage。If it is a vehicle of better quality,Looking bright and beautiful on the outside。

At this stage, the vehicle must focus on the following aspects of inspection and maintenance:

1.Brake pad

Brake pads are the most critical safety parts in the car’s braking system,The brake pads play a decisive role in all braking effects。Replace the brake pads in time after using the friction material,Otherwise the steel plate and the brake disc will be in direct contact,Eventually the braking effect will be lost and the brake disc will be damaged。Generally,The replacement cycle of the front brake pads of a car is about 30,000-50,000 kilometers,The rear brake pad is about 60,000-80,000 kilometers。The reasonable replacement cycle of the brake disc is to replace the brake disc after replacing two sets of brake pads。The common brake oil replacement interval is 2 years or 50,000 kilometers。The brake system needs to be inspected regularly,If there is a problem, replace it in time。

2. Fuel pump

The car has been driven for more than three years,It’s almost time for the fuel pump to be cleaned or replaced。

3.Shock absorber

If you find that the driving is not as smooth as a new car,When encountering this situation, you should check the car's shock absorbers。The function of the shock absorber is to reduce the vibration of the car,It is part of the suspension system,If the spring of the shock absorber is no longer elastic,It will vibrate badly when driving at high speed,It is especially dangerous on rainy days。

After driving the vehicle for ten years,It can be said that the performance of cars is declining year by year,Serious illness 369、Minor illnesses occur every Seabetday,The cost of maintenance is also increasing year by year。During this period,Some oil seals and seals have aged,After finding the fault, it should be rectified immediately and thoroughly,Otherwise it will result in higher repair costs。Rubber parts、Air conditioning、Car paint、Problems in the power system and other aspects will be more prominent。The vehicle’s power performance is reduced,It is caused by contamination of the oil system,Clean the engine on time、Changing the engine oil on time will alleviate this situation。

Warm reminder:Car maintenance must be strengthened during this period,Regular replacement of wearing parts，Go to the repair station or maintenance center from time to time to check the condition of the vehicle。

After using the car for ten to fifteen years，，Various hidden、Obvious dangers begin to appear。Like a dying patient，There is a danger of becoming critically ill at any time。The same goes for cars of this period，Car owners are also uneasy when using it，Lest it rest on the road。

Therefore，A car from this period，You must have "not afraid of hardship"，The spirit of not being afraid of death，If you don’t have this fearless spirit，You'd better let it stay in the garage to recuperate，Or send it directly to the scrap station to sell it for scrap。At this stage，Most car owners choose to replace their cars with new ones，Replace old car。

Car at this stage，Pay close attention to every action you take，Take careful care。Check whether there are any oil or water leaks under the car before getting out of the car，After the vehicle moves, step on the brakes and check the brakes，For safety while driving，Car owners must be more careful。

Although my country has canceled the mandatory scrapping period for non-operating cars，But when the car reaches this stage，The performance of each component is no longer as good as before。In actual use，Try not to increase the engine speed too high，And aggressive driving should be avoided，In this way, the car can successfully complete the remaining distance。

1.Power system maintenance: if the vehicle is more than 10 years old，More than 150,000 kilometers traveled，The engine may seabet ioneed major repairs，And the transmission oil needs to be replaced，Check whether the engine oil is leaking；

2. The water tank needs to be thoroughly cleaned;

3. Check the chassis for any major damage or rust.

4. Check whether the suspension shock absorber is leaking oil and repair it.

5.Tires、The battery etc. should have been replaced several times，Pay attention to periodic inspection and replacement。

Experienced these 5 cycles，The life of a car is also coming to an end。(The article comes from the Internet，If copyright is involved, please contact us for deletion)
