Why don t 4S shops generally repair engines on a large scale?

The 4S shop also has an overhaul engine service, but the overhaul of the engine is almost the largest operation in car maintenance, not to mention the current overhaul mileage, do you know how much it costs to overhaul the engine in the 4S shop? Overhaul engine is the most ruthless project in the 4S shop, any B-class car overhaul engine is at least 20,000 yuan to lay the bottom, this is still the negotiation before the engine is opened, and after opening the engine there are other unexpected problems, you have to continue to add money, combined with the 4S shop that the price of the working hours, a slightly better car overhaul has to be more than 30,000 yuan, is it worth spending so much money? Ordering an engine directly, such as EA888, is not at this price, so the cost performance of overhauling the engine is too low!

The car itself is constantly depreciating, and usually it is the old vehicle with a mileage of more than 300,000 that has the significance of overhauling the engine; But how much is the car worth at this time? Do you want to spend such a big price to go to the 4S store for overhaul? For example, a B-class car of about 200,000 yuan, if you just take a car, it will take about 10-15 years to run out of 10,000 kilometers, and the car at this time can not buy a few dollars, is it difficult to spend nearly half of the car to overhaul?

As a result, after the repair, the car still could not be sold at a high price, and it was a completely loss-making transaction, and it was a big loss;

Therefore, even if it is like a major repair, there is no need to go to the 4S shop to overhaul, it is better to find a skilled master to lead the knife; It's not that the 4S shop doesn't overhaul the engine, but few people overhaul the engine will consider overhauling the engine in the 4S shop!

Another point is that the times have changed, consumers' attitudes towards cars have also changed, and the technology (process) of car manufacturing has also changed a lot; In the past (decades ago), cars were expensive, and it was really not easy for ordinary people to buy a car, and at that time they usually had the idea of using a car for a lifetime.

So at that time, no matter how big the problem was, I would definitely choose to repair it, because at that time, changing cars was not as casual as it is now! In the past, the technology and technology of car companies were far less developed than they are now, I remember when I was a child, I heard an advertisement for a certain engine oil, the advertising slogan was the use of xx engine oil, 100,000 kilometers without overhaul, and later this advertising slogan was upgraded to 300,000 kilometers without overhaul, in fact, in the 90s of the last century, this advertising slogan was seriously untrue; Now it is different, the car is cheaper, and it is easier for consumers to change cars, so there are few ideas to drive a car for a lifetime; And now the engine runs 100,000 kilometers like child's play, and there is no need for major repairs; Running to 300,000 kilometers can choose overhaul, can also be dealt with, because the past engine in that lack of normal maintenance era, can run to 300,000 kilometers almost are terminally ill, not repaired at all (imported Japanese cars can be a lot stronger), and now even if the car is not repaired for 300,000 kilometers, at most it is serious oil burning, and others can be used! So now the practical significance of overhaul has been reduced a lot, because many cars usually run less than 100,000 kilometers before they are processed!

Inferior oil, foreign matter in the engine, long replacement cycle of filter element, inferior antifreeze high temperature, excessive carbon sludge, etc., these problems will almost not happen if they are often maintained in the 4S shop, and now the engine technology is very mature, especially in the warranty period without special circumstances will not overhaul the engine. In addition, the 4S shop has a maintenance history of the vehicle, and the staff can recommend maintenance items according to the resume, and the 4S shop is full of original and regular accessories, so the probability of problems is not large.

The cost of repairing the engine is relatively high, so generally 4S shops do not repair on a large scale.

Because large-scale repairs to the engine will reduce the performance and life of the engine.

Because the 4S shop does not have such conditions, repairing the engine requires a high level of skill.

It's because of the large-scale repair of the engine, the cost is too high to be worth it.

Because large-scale engine repair requires a lot of manpower and money.

4S shops generally sell cars, and if there are a large number of assistant engines, it is not an auto repair shop.

Because generally inexperienced maintenance workers, dismantling may not be able to complete the engine back up.

Yes, if there is a fault in the motor vehicle, you need to contact the after-sales service department of the No. 4 S store, use the detection computer to determine the cause, and repair it by displaying the reason to effectively solve it.

There are not many owners who overhaul their engines in 4S shops, and most of them go to repair shops outside. One of the most important reasons is that the 4S shop ** is too high, and the overhaul cost is as little as 10,000 or more than 20,000 or 30,000.

The important thing is that the cost of working hours accounts for a large part, accounting for one-third of the total cost or even higher. Although the cost is high, the accessories are all original parts, which are more compatible with the original car parts, and the quality and reliability are more guaranteed, which is incomparable with the repair shops outside.

The vehicle cannot continue to drive:

It will affect the vehicle engine to a certain extent. Once the engine is turned off, it will affect the driving safety of the motor vehicle. After the motor vehicle fault light is turned on, it must be repaired as soon as possible, judging by observing whether the engine is shaking or making noise.

The engine lacks oil, the engine lacks cylinders, and the vehicle spark plugs.

It's not working properly, there's a problem with the injectors. Ignition coil.

There is a malfunction. There is a problem with the vehicle's air intake system. These faults require physical maintenance, which can be effectively eliminated and make the vehicle run normally.

There are a few reasons why an engine needs to be overhauled:

1. Decline in power and economy; For example, the vehicle is weak, the oil consumption is too high, and the gasoline consumption is too high;

2. The sound of the engine is abnormal; For example, the abnormal sound of piston pins and connecting rod tiles;

3. The oil pressure is too low, and the alarm is frequent; Generally speaking, the engine must be well cared for and regularly maintained at a qualified service station, which will reduce your trouble and prolong the service life of the engine.

Overhaul is to break up the entire engine for maintenance, the general overhaul is because of the burning of oil, internal accessories wear, can only break up the entire engine for maintenance, not scattered can not be repaired and installed? For example: piston rings, pistons, tiles, boring cylinder grinding shafts, etc.

There are other reasons that need to be overhauled, such as: high engine temperature, pad holding caused by oil-free driving, and the engine needs to be overhauled.

Usually, the 4S shop will recommend that the engine starting system of the car should be overhauled every six months or every 5,000 kilometers. So why does the 4S shop recommend this to car friends? Let's take a look. <>

According to the experts of the 4S shop, there are two conditions for the maintenance of the system of engine start-up of the car: every 6 months or every 5,000 kilometers driven. If these two conditions are met first, then it is necessary to carry out maintenance.

For example, only 4,000 kilometers in 6 months also need to be repaired. In addition, experts also recommend that the oil level should be checked every 1,500 kilometers for turbocharged engines, and around 2,500 kilometers for other models.

The maintenance method of the engine starting system is mainly to take the following points.

1. Maintenance of the throttle. There will be more oil sludge at the throttle, so the continuous discharge of fuel exhaust gases will form carbon deposits or sludge at the throttle, and if there is more greasy, it will produce gas resistance and increase engine fuel consumption. Excessive carbon deposition will also cause difficulty in starting the engine, which may cause symptoms such as oil blockage, failure to atomize, severe deformation of gasoline injection, etc., and if you continue to drive, it will cause serious damage to the engine, and this damage is usually final.

2. Maintenance of air filter. It can be said that the air filter is directly related to the air intake problem of the engine, because the air filter will continue to block as long as the vehicle is slow to drive, and the dust in the air will gradually enter the air filter. This is an inevitable problem that riders should pay attention to.

3. The maintenance of the engine starting system also includes the replacement of oil and the oil of other components. The role of these maintenance should not be underestimated, as it can reduce the weight of the engine and improve the performance of the engine, creating a good operating condition for the engine. <>

At present, the engine starting system has gradually changed from the previous maintenance concept to the form of daily maintenance. Regular maintenance can make the car provide better convenience for our lives!

4S shop will generally carry out a reasonable overhaul program for the car, each car needs maintenance, when it needs to be overhauled, the 4S shop will remind the user to overhaul the starting system of the car engine in time, and will be checked in every car maintenance process, the car maintenance master in the 4S shop will verify the sound of the car engine, the speed of the engine and the state of the engine, oil temperature, water temperature and a series of parameters, and will read the data data of the car ignition through the computer. The closed base can clearly see whether there is a problem with the engine starting system of the car, and if there is a problem, the user will be informed whether to overhaul it, and put forward reasonable suggestions and good improvement plans in general. Car 4S shops will recommend that the car be serviced once a year or every 5,000 to 10,000 kilometers. <>

1. What is an automobile engine starting system?

The automobile engine is not free, from stationary to working state, so in order to make the engine ignition start, it is necessary to rely on external force to push the crankshaft of the automobile engine will gradually provide speed to the engine, until the engine normal combustion speed, in order to lead to the compression ignition of the engine in this process, and to be able to normally let the crankshaft provide enough power to the engine, the engine from stationary to the working process of this action, we call it the engine starting process, In the engine starting process, the starting device of the engine needs to be installed and arranged, and the starting device of the engine is generally divided into key start and keyless one-button start in the existing car, and the battery is heard to provide sufficient voltage to push the engine power. <>

Second, pay attention to whether the engine starting device is damaged.

Many car owners in the vehicle ignition can not be ignited normally, generally do not care about the second ignition of the fire, but do not know if the car can not be ignited normally many times, then it is necessary to pay attention to whether the battery voltage is low due to frequent ignition, there is no way to start the engine or the engine starting device, the starting system is faulty and not found, resulting in the ignition system has no way to start the engine normally. In this case, it is necessary to go to the auto repair shop and 4S shop for inspection and maintenance in time. <>

It can be seen from the above aspects that in the 4S shop, car maintenance will generally be carried out every 5,000 to 10,000 kilometers, and a reasonable car maintenance plan will be formulated.

It is about three months, and after the vehicle has traveled to 5000 kilometers, it should be checked in time, and then it should also be maintained in time.

Under normal circumstances, it is necessary to overhaul every year, which is determined according to the condition of the vehicle.

If you are in a 4S shop, they will recommend that the engine starting system of the car be overhauled every 5000km.

Car maintenance does not go to the 4s shop separately:

1.It is recommended to go to a 4S shop for maintenance of a new car. It's not because of love for new cars, but because the manufacturer will give the new car a certain warranty period, and if the vehicle is free, if the quality problem is free, it will be fixed.

If you do not pay for 4s maintenance as specified by the manufacturer, this warranty will be void. It sounds a bit like Rumens, but it's actually understandable. If you don't go to 4S maintenance, it will go into an external repair shop crack.

The manufacturer could not be sure that the problem was that the manufacturer's quality was still caused by improper repair factors.

2. After the warranty period is over, it is not necessary to go for 4 seconds, but pay attention to a trustworthy repair shop.

In fact, the maintenance of the technicians is not high, and the 4s are also very good to repair the factory. Even an apprentice can carry out maintenance, the problem is the oil and accessories used. Some unhealthy repair shops will use low-quality oil and accessories for charging, which is very harmful to the engine, and don't expect the repair shop to inflict 4 years on their own life, the repair shop generally does not admit it.

Therefore, in repair shop repairs, it is necessary to choose a reliable maintenance repair shop.

Personally, there is no warranty period in a new car, and if you have any problems, it is better to go to the 4S store. At the end of 2013, the corresponding policy of "three guarantees for automobiles" was issued, indicating that car manufacturers can repair, replace and return, replace and return this product quality, and I hope that every consumer will not satisfy every consumer. for this case.

First of all, convenience. First of all, I will promote the concept of 4S store, why is it called 4S store, because it integrates the four car service functions of sales (**), spare parts (sparepart), after-sales service (survey), information feedback (survey), so the convenience mentioned here means that you need to solve any problems and can only go to this 4S store. If you leave the 4S shop, you can do minor maintenance and need to go to one place, but you need to go to another place.

Secondly, the 4S shop will provide a more comprehensive record of your car, such as some kind of familiar maintenance, or which part to repair. In the long run, it has formed feedback on the use of the car, even if you need the benefits of selling the car, and there is a full 4S shop history that tends to be favored by the next pricing owner, and you have Dimension Guess and repair in a non-4S shop. At this stage, having such a record always gives the feeling of being official, not to mention that most stores don't make such a record, and like I said earlier, you can't have all the problems.

Finally, some need to live meticulously, 4S store is not necessarily absolute, but it is true that the late source type is very detailed. The 4S store has a comparatively more standardized system of operating processes, and the tool also facilitates and completes, so to use the big white word, it is not active. So why is there a special complex and tedious job trying to pay the 4S shop, on the one hand, there are special attacks in the industry, and on the other hand, even other repair shops can do it, maybe in the arena, the workers do without standardized constraints, and the randomness is still stronger.
