The engine is seriously damaged, is it more cost effective to replace it directly or overhaul it?

I believe we all know that the engine is a very important part of the car, so many people attach more importance to the engine, but now the weather is hot, resulting in the engine will be easy to be damaged, and the engine will be more serious if you don't pay attention, so some car owners are very puzzled, if the damage is really serious, is it more cost-effective to directly replace it with a new one or to repair it well?

First of all, we have to look at the damaged parts of the engine, some places may still have the value of repair, and some places are damaged after the need to send it for repairThis mainly depends on the location and extent of the damage. Because if you directly replace the engine, I don't know how well the car will match itIf the replacement is carried out directly, more failures may occur.

And before replacing, you should carefully inquire about the comparison between the two, first of all, you must have an engine data in mind, and then ask how much it costs if you want to repair itIf you want to repair more than half of the new engine, it is recommended to replace it with a new one.

In fact, car maintenance is a very important item now, if you can maintain it well every day, you can avoid engine damage as much as possible, saving a lot of money.

For example, do more engine cleaning in ordinary times, we know that the engine is very easy to produce carbon deposits, if there is too much carbon deposits, it will make the engine power insufficient, increase fuel consumption, and easy to make the quality of exhaust emissions not up to standard, so it is necessary to regularly clean up the surface and interior of the engine, so as not to damage the engine.

In addition, when the weather is hot, do not let the engine be in a working state for a long time, because the engine itself will produce a lot of heat when working, if it works for a long time in a hot weather, it is very likely that the engine will have a spontaneous combustion accident, so let the engine rest after starting for a while, especially the driver who runs long distances should pay special attention to this, and also consider it for their own safety.

There is also a need to pay more attention when refueling, one is not to mix the two brands when adding engine oil, and do not mix and add different models of gasoline, because the proportion of ingredients in it is different, and mixing and adding will have a certain damage to the engine.

Protect and clean up the engine in daily life, if there is some small damage, it should be cleaned up in time, and if there is a big damage, it is necessary to compare it and then decide whether to replace it or repair it, so that there will be no loss.

It's better to just replace it with a new one, because after repairing it like this, isn't the effect still not very good?

If the engine is badly damaged, it is more cost-effective to replace it directly, because if it is overhauled, it may break down later.

This is better to replace it directly, even if the overhaul is repaired, it is easy to have problems.

I think if it's badly damaged, it's better to get a new one. Otherwise, the overhaul will not be done.

I think it's more cost-effective to change directly, and it will cost a lot of money to overhaul.

It's better to go to a repair shop and let people take a look at it.

I think it's more cost-effective to switch directly. Because overhaul may not solve the root problem.

I think it's more cost-effective to switch it directly, because if you fix it, it may break again, so it's not cost-effective.

Look at whether the damage is serious or the damage part, and the damage to the serious or important parts is still directly replaced.

I feel that it is new, as long as it has been dismantled, it is less good.

Change, contact the manufacturer to ship, cheap. I have a Kaima light truck, and the overhaul will cost more than 5,000, and I will come back with a new one for 4,800

People are composed of a lot of limbs and internal organs, they have a clear division of labor, each doing their job to coordinate the work for our brain, but sometimes we will also get sick, the car is the same, for the car engine is like the human heart, once it is broken, it will have to be operated, then the car engine is broken, it is better to replace the engine with a new engine or overhaul, follow along to understand.

Fewer kilometers can be overhauled.

Newer cars are very good in terms of performance and durability of hardware facilities, at this time the engine is broken, it may be just a part of the engine is broken, and the parts are still very good after overhaul, generally speaking, the car within 100,000 kilometers in 5 years, in the absence of frequent violent driving, even if there is an engine failure, most of them are only piston or valve failures, the difficulty and cost of maintenance are bearable, and the effect after maintenance is immediate, Most of them can continue to use normally for 100,000 kilometers without major problems. The total number of general repairs is about 30% of the replacement of the engine, and it is more cost-effective to repair it.

Old cars are not recommended to be repaired.

Old cars, whether it is the engine or other hardware, may be on the verge of scrapping, so it is okay to overhaul the engine and damage other spare parts. For some old cars, overhaul is actually of little significance, even if all parts are replaced, the effect cannot be restored to the same as the original car. For example, a 90-year-old man had a heart attack, and he was replaced with the heart of an 18-year-old young man, and the heart was fine, but no one can say how many years the old man can live a long and healthy life.

The most economical way to do this is to replace it with a dismantling part, but this practice is also risky. After that, the maintenance accuracy of the market is far from the original factory, so even if the engine is overhauled, it cannot give you the warranty of the original factory, and generally speaking, it can continue to be used for 2-30,000 kilometers, even if the overhaul is good. Therefore, it costs tens of thousands of yuan to drive only 20,000 kilometers, and the solution to the problem of burning engine oil with some abnormal noise is not obvious, and it is very cost-effective.

For the car engine is broken, the engine is replaced or overhauled, and the most important thing is to decide according to the age of the car itself.

Overhauled. Because the engine overhaul costs less, and the engine is too expensive, it is better to change the car directly, so I think it is better to overhaul it.

If it is broken, it is recommended to replace it with a new engine, even if it is repaired, it will still break down after a short time, and replacing it with a new one will also help the car.

If the car engine is broken, it is better to change the engine, and the overhaul is not low, and it may not be repaired, so it is better to change the engine.

If the car engine is broken, it is best to replace it with a new one, because if the engine is overhauled, the engine may still fail.

It's better to change it, because even if it's repaired, there will still be problems after a long time, and once and for all, it's better to change one.

No engine is repaired, even if it is repaired, it is only 350,000 kilometers, and the engine is repaired

Overhauling an engine also depends on the reason for the engine overhaul. If the cylinder head gasket leaks into the cylinder and then there are no parts inside the engine that are damaged, the overhaul may be to remove the cylinder head and replace some repair kits. So the overhaul is not expensive.

If the engine needs a major overhaul because there is too much sludge inside, then there is no need to replace the engine with a new one, only some repair kits. The engine is not replaced at will, for example, if you replace the engine in our country, you can only replace the same model (the same power version), and you must also have an invoice for the new engine, so it is inevitable that the cost of replacing the new engine is relatively high, and for some good cars, if you choose 4s to replace the new machine, it is higher, so this is the pain point of replacing the new machine.

For example, the residual value of an old car is only 2000 or 3000. Replacing a new engine may require more than 1000 or 20000. Won't you replace it at this time?

The engine is not changed at random. For example, in China, the replacement of an engine can only be replaced with a new engine of the same model (same power version) and must have an invoice. Therefore, the relatively high cost of replacing a new engine is inevitable.

For some good cars, if you choose a 4S store to replace a new machine, the ** is higher, so this is the pain point of replacing a new machine.

For example, the residual value of an old car is only 2-3, and it may cost more than 10,000 yuan to replace a new engine with 10,000-20,000 yuan. If the engine burns oil and causes an overhaul, such as piston rings and valve seals causing oil to burn, it is generally measured that there is no problem in the engine cylinder, i.e. replace the piston rings, valve seals and some repair kits. Therefore, there is no need to replace the engine with a new one.

Of course, you can replace it with some dismantling machines and second-hand machines, but the engine changes cannot be done and will eventually leave hidden dangers in the subsequent use of the vehicle.

Therefore, it is best to replace the new machine once and for all, but it will be more expensive, but it is also relative (it is undeniable that the overhaul machine of individual auto repair shops is more expensive than the new machine, all kinds of new parts), from the ** point of view, the 4S replacement engine is ridiculously expensive (such as BBA but any model, at least 100,000 yuan in 4S); In contrast, some better and newer cars are more suitable for new machines, because a good car overhaul is not cheap! Of course, it can also be replaced by some dismantling machines and second-hand phones, but the engine replacement cannot be completed, which will eventually leave hidden dangers for the subsequent use of the vehicle.

It's good to change the engine, because changing the engine can completely solve the problem, and there will be a lot of minor problems after the overhaul, so I think it's better to change the engine.

I think it's better to get a new one, because the performance of the engine will be reduced a lot after the overhaul, which will affect the driving experience.

I think it's better to choose an overhaul, because it is too expensive to change the engine, and a new engine can top the original car **1 4.

Durable.

The engine can generally be used for 5 to 10 years after the overhaul is blocked, and it can travel 100,000 kilometers. Because the mileage of the engine will be shortened after the overhaul, in order to be able to restore the performance of the engine to the factory performance as much as possible after the overhaul, the engine needs to be disassembled during the overhaul, and the piston, piston ring, valve, timing chain, and grinding shaft oil seals need to be disassembled.

and other parts for inspection, repair, and even replacement. Therefore, after reinstallation, it will also have a great impact on the service life of the engine.

Engine maintenance precautions.

1. In order to ensure the service life of the engine, it is necessary to drive at the normal temperature specified in the car manual.

2. During the run-in period.

In order to be able to prolong the service life of the engine, it is necessary to carry out running-in according to the regulations.

3. Check the condition of the engine frequently and fasten the parts frequently. If there is a loose part, it should also be tightened in time to avoid the impact on the normal use of the engine due to the lack of blind fastening parts.

4. When changing the oil and adding fuel to the car, you must choose the most suitable one.

If the car engine is broken, it is better to replace it with a new one, and it is cheaper to replace it with a new one. The car itself is a consumable product, and with the passage of application time, it is inevitable to encounter a variety of large and small problems. If there is a larger common fault in the car engine has already affected the daily operation of the car, it should be replaced or replaced and repaired immediately, no matter what kind of car engine it is, the prerequisite is to use a certain type of fuel combustion to cause the driving force.

Therefore, the motor as an electric energy source is not within the scope of automobile engines.

If there are too many common faults in the car engine itself, there is no point in repairing it, and it must be wise to replace it immediately. But it is not necessary to replace the car engine to repair it is not realistic, the overhaul engine of the vehicle is relatively old, for example, the age of the car has reached more than ten years, and the parts of the car are not expensive, the replacement engine charging standard is also correct, if the maintenance of the engine and the replacement of the car engine are not too much, then choose the domestic engine! You can consider disassembling and disassembling the engine, and the natural disassembly of the engine also requires quality clearance.

Compared with the new car, whether it is the function or hardware condition of the degree of solidity, is very good, at the moment the engine is broken, there may be just a certain component in the car engine broken, through the maintenance of the component is still good, generally speaking, more than 5 years more than 100,000 kilometers of vehicles, in the absence of any often violent driving situation, even if the engine common faults, most of them are just piston rods or cylinder common faults, repair the difficulty coefficient and cost can be afforded, Moreover, the effect after the overhaul is immediate, and most of them can continue to start normally for more than 100,000 kilometers without problems.

Generally, the price of maintenance is about 30% of the replacement engine, and it is more cost-effective to repair it. The old car, whether it is the car engine or other hardware configurations, will be on the verge of damage, so it is possible to repair the engine and destroy another part. For some old cars, repairs don't really make sense, and even if all the parts are replaced, the effect will not be restored to the original factory.

I think if the engine is broken, it would be better to replace it with a new one; Of course, it will be cheaper to carry out repairs, but it may not be as durable after repairs.
