Chapter 170 If you don't buy it, you don't need maintenance
Chapter 169: If you don't buy it, you don't need maintenance
Fang Yuan understood that car maintenance was very simple before he acquired basic skills in used car maintenance and maintenance.

In his impression, car maintenance is the same as a roadside car wash. Use a high-pressure water gun to wash the dust outside the car, clean up the garbage inside the car, and throw away all the dolls, pendants, and floor mats left by the previous owner. New ones, then brush the wheels, at most polish and wax, and finally the car owner pays tens or even hundreds of dollars to leave. Only those local tyrants will seal the glaze, coat the film, and paste the invisible car cover...

Fang Yuan understands that car maintenance is equally simple, that is, changing the engine oil, changing the spark plug, changing the engine filter and so on.

Fang Yuan realized that what he had thought before was too naive and too simple after he acquired the basic maintenance and maintenance skills of second-hand cars.

Because the maintenance of used cars is basically one.

At different ages of a car, even if it is exactly the same model, the maintenance items are completely different at different ages. The water inside is also very deep, and new car owners will be cheated if they don't pay attention.

Fang Yuan made an analogy based on the information provided by the basic preparation and maintenance skills of second-hand cars. He divided the purchased second-hand cars into four stages of life.

A quasi-new car that has just left the factory is like a baby. At this time, all the organs in its body are like a blank sheet of paper. It does not smoke, drink, or have any bad habits.

Except for the problem of congenital fetal belt, there will not be any infectious disease, malignant tumor, or cancer, as holy as an angel.

Therefore, for normal second-hand quasi-new cars to do maintenance, you only need to do maintenance according to the time and cycle suggested in the maintenance manual of the car, and change the engine oil, oil filter element, air filter element, air conditioning filter element, fuel filter element, spark plug, brake oil, and transmission on time. Tank oil, power steering oil, etc.

Of course, these items are not to be done every time. They should be determined according to the maintenance manual. For example, a popular model of Volkswagen recommends changing the oil and oil filter element every [-] kilometers, and changing the air filter every [-] kilometers. And cabin filter, replace the spark plug every [-] kilometers, and replace the gasoline filter every [-] kilometers.

Therefore, if you buy a second-hand quasi-new car in the second-hand car market, it is like welcoming a new life into your home.

When buying a car, please ask a third-party testing agency, or a knowledgeable friend to do a second-hand car test to identify the condition of the car.

In the following car repairs, the shock absorber rubber sleeve of the chassis is generally not replaced, the timing belt is not replaced, and the throttle valve, fuel injector, intake duct, and engine interior are not cleaned.

If you buy a second-hand quasi-new car for maintenance, and the auto mechanic recommends an engine cleaning package after changing the oil and oil filter, then don’t think about it, he is 100% trying to cheat people.

A good-tempered car owner can ignore him and leave directly, and then add this store to the blacklist, so that you don't have to come back again.

A bad-tempered car owner can take the largest live-end wrench and point it at his nose first, and then point at his beloved car, and tell him that the car is two years old. Are you looking for a beating?
What I said above is that normal models don’t need to worry too much, follow the time and cycle suggested by the maintenance manual attached to the car, and the maintenance items are also very simple.

Of course, there are also some abnormal models, such as Golf GTI, Focus RS, Toyota 86 and other performance cars.

Such as Prado, Wrangler, Jimny and other off-road models.

Because golf GTI, Focus RS, Toyota 86 and other models are bought for fun, otherwise who would spend hundreds of thousands to buy them?
Wouldn’t it be nice to buy an Audi A4L, Toyota Camry, or Volvo V40 with more space, more comfort, and higher configuration for the same price?
Since it is for fun, those new car buyers will not cherish the car after they buy it.

I can’t wait to see someone’s disk at [-] times a day, I can’t wait to start off every time I go out to buy groceries. It’s not crow’s feet that flick, flick, flick, flick, what’s burned may be the clutch plate, and what’s destroyed may be the gearbox. It could be the engine.

Therefore, for the sake of your own safety and wallet, you should pay attention to second-hand performance cars such as Golf GTI, Focus RS, Toyota 86, etc. Even if the car is a few years old, you must be extremely careful, and pay attention to the clutch during maintenance. Chips and other key parts should be replaced. Don't try to save trouble or money. ,
Off-road models such as Prado, Wrangler, Jimny, etc. are also very aggressive.

Soaring to the sky, clearing the sand, digging through the jungle, and passing through the shell crater, the original car owners tried hard every day, and sold the car when they got tired of playing, but it hurt the second-hand car buyers.

So when you see these models, you should be careful. Even if the car is a few years old, it is important to check the oil pan, shock absorber, engine, etc. during maintenance.

The last one is the battery.

Some original batteries are easy to lose power. A quasi-new car that is one or two years old will not start up if it is left for a week without driving. This is a natural tire belt problem.

During maintenance, use a battery tester to check to see how much the battery has attenuated. Anyway, the price of the battery is not expensive. You can buy a very good one for about [-]. If it doesn’t work, let’s replace it. .

The second stage is to reach the young and middle-aged of life, and start drinking, smoking and socializing.

When young and middle-aged is the peak period of the car, and the manufacturer's warranty often expires early, but at this time, the buckles of the interior plastic parts have fallen off, cracked, and deformed.

Especially the central control part, some models must be replaced if they want to change, otherwise they can only bear it and listen to the symphony in the car every day.

The shock absorber rubber sleeves, rusted parts, tires and timing belts of the chassis should also be paid attention to at this time, especially those car owners who often run at high speeds should pay special attention to maintenance.

Furthermore, certain models begin to show signs of engine carbon deposits, engine oil burning, oil leakage, and gearbox oil leakage. It may be just the beginning, but you must always be careful.

The third stage is the most important stage of old age, when diabetes, high blood pressure, and hemiplegia begin to appear.

At this stage, the overall performance of the car has declined seriously, various common problems and problems have erupted, and the condition of the car is in an unstable state. You must be 12 points careful during maintenance.

The first is the problem of burning oil.

German cars, French cars, and even some Volvo, Toyota, Lexus, and domestic cars have the problem of burning oil.

Old and frail, it is normal to burn engine oil and leak oil. At this stage, second-hand cars do not burn oil or leak oil, and the engine compartment is spotless. They are so new that they have no friends. There is no doubt that there is 100% problem.

Secondly, the fuel system and lubrication system of the engine need to clean the oil circuit and fuel tank. This is because the fuel used normally is made by refining crude oil, and the quality of the fuel is improved for the convenience of combustion, so that the fuel can be stored for a longer period of time. , some additives are usually added, and these additives will gel and coagulate after a period of time, and after accumulating to a certain extent, they will adhere to the oil circuit and the fuel tank.

This kind of deposition will affect the delivery of fuel, and even affect the normal operation of the fuel injection system, and the deposition of the fuel tank will accelerate the deterioration of fuel.

In order to avoid recurring problems after cleaning and to maintain a healthy state, you can use higher-level engine oil and use fuel additives, which can improve the combustion of fuel in the combustion chamber and slow down the pressure of abnormal combustion of fuel on the engine block.

The third is to maintain the gearbox, replace the clutch plate, timing chain, etc.

Although the vast majority of brands now claim that their gearboxes and timing chains can be maintenance-free for life, it is best to carry out maintenance at this stage. Even an inconspicuous timing chain may cause top valves. Overhaul the engine.

Secondly, there are four wheel alignment, replacement of shock absorbers, suspension pad replacement, control panel, fuse, etc., which need to be checked during maintenance.

The fourth stage is the real twilight years, when the performance of the car is seriously declining. For the sake of your own safety, in addition to practicing hands and buying a car after modification, if you can not touch such a second-hand car, you should not touch it. If you don’t buy it, you don’t need to maintain it. up.

……

In front Huzi and a few partners were busy, Fang Yuan strolled over.

Fang Yuan had heard from Liu Liang that Zhao Dezhi’s Sanxin Auto Repair Shop was similar to Lao Wang’s Auto Repair Shop. They used the name of an Auto Repair Shop, but they mainly focused on the repair and maintenance of second-hand cars. something wrong.

As for overhauling the engine, changing the clutch plate, changing the lifter of the convertible, etc., sorry, that is the job of a professional auto repair shop or 4S shop, and they can't do it all.

Huzi was standing under the lift to change the oil of an old BMW.

Fang Yuan happened to have never seen it before, so he stood aside curiously.

Don't look at the young tiger, he works very neatly. After quickly loosening the oil pan screw to a certain extent with a wrench, he immediately switched to holding the top of the oil pan screw with his hand, and then quickly pulled it out. The dark engine oil flowed down.

But when the engine oil was drained, and when Huzi wanted to reinstall the oil pan screws, he turned around and searched for a long time, but he forgot where to put the screws.

Huzi really couldn't find it, so he just found a similar style and wanted to put it on.

"Huzi, wait a moment." Fang Yuan's eyes widened in surprise and asked Huzi, "Don't you know that the oil pan screws of this BMW are made of aluminum? Can you just find one and use it?"

"It's made of aluminum? As long as it can be installed, isn't it all right?" Hu Zi couldn't understand Bi Fang Yuan, looking at Fang Yuan flickeringly with a pair of big eyes, and he hasn't figured out what's wrong.

"Okay, put it on, let me see if you can put it on."

　Thank you for the 100 rewards from my friend "The Diehard Fan of Bullet Cases"
　　thanks for your support.
