Installing a contract engine is much easier than making an overhaul of an existing one. It should be noted that the overhaul does not give an absolute guarantee to improve its performance. Usually after a major overhaul, the engine's service life is reduced, and reliability and horsepower are lost, and gas mileage may increase. And many motorists are thinking about whether it is worth repairing an engine at all, if buying a ready-made hub, which remains only to put in its place, is much cheaper.

And if we still recall that we have very few specialists capable of carrying out high-quality repairs, the choice falls precisely on the purchase of a contract engine. Most of the masters specialize in domestic cars, and the share of those engaged in the maintenance of foreign cars, is much smaller. And you are unlikely to give the car a foreign production in the hands of a man who knows nothing about him. Therefore, we will consider in more detail what a contract engine is, what requirements should be placed on it, and what is the advantage of installing it.

Characteristics of contract engines

There are firms that are engaged in the selection of contract engines

The contract engine is an engine that is installed instead of the old one, moreover, taken from a car of the same manufacturer of the same brand. But, as you know, there are analogues that are ideally suited for several models. Also, sometimes in the model range of one (or several) manufacturers, one can find interchangeable engines. The list of requirements for contract engines:

1. His removal from the car must be absolutely legal (no crime, including you can not purchase the internal combustion engine, extracted from the stolen car). Check all documents - sales contracts, customs declarations, etc.
2. Check engine performance before purchase. Yes, he will have some kind of mileage, but his characteristics should be close to perfect.
3. All attachments must be installed on the engine. If you are trying to sell only a block with the cylinder head, then refuse such a purchase.

Perhaps these are all the requirements that need to be considered when purchasing. But remember that you need to hire a good installer who will remove the old motor, put the contract in its place, and also perform all the procedures for connecting it.

To install the contract engine is better to invite a specialist

Origin of contract engines

Unfortunately, only in our country cars drive as long as, literally, they do not start to crumble. Many people drive cars that eat oil and consume a lot of gasoline, and they release so much CO into the atmosphere that the party of greens would go crazy. A completely different picture in Western countries - the operation of such cars is punishable, and severely. And if you suddenly got a road inspection, then you will write out a considerable fine. Even the confiscation of such a car is not uncommon (which, however, will occur only when you re-caught the police).

Germans, Japanese, Americans, as well as many Chinese, change cars every five years. Salary allows, why not buy a new one? Even after light accidents, they do not bother, and buy a new car. For us, it seems wild, because it is possible to repair and continue to safely operate the car. But no, the mentality is completely different. And if you take into account the fees for cars that people pay abroad, the picture becomes clear - the tax on a new car is many times less than a five-year one. And such cars go to other countries. Some are immediately sold (if there are no defects in them), others are repaired, and still others that cannot be repaired are simply dismantled and sold for parts.

Most recently, the Russian government issued a law according to which the car's engine is considered to be a spare part, its number does not need to be indicated in the vehicle passport. This means that you can install a similar one instead of your old engine without paperwork.

European engines

Choosing the engine from Europe, the main thing is not to buy "drowned"

European cars drive on perfectly flat roads, which, oddly enough, has a positive effect on the engine. The climate in most European countries is not as severe as in our country, therefore, the motor does not experience overloads during warming up in winter. It is also worth noting the high-quality gasoline (or diesel), which is poured into the tank, and the use of good motor oils. And all these nuances affect the service life of engines. And do not forget about the scrupulousness of the inhabitants of European countries - most of them then pass most of them in a timely manner, without delay, otherwise the warranty on the car simply burns out. If you decide to purchase a contractual internal combustion engine, be careful - it can be removed from the "drowned" car. True, today at reputable firms-dealers, you will not find such motors. Everyone wants to sell quality spare parts to their customers, because the company's image depends on it.

Engine selection from Japan

As for the Japanese, they change cars every 3-5 years. Cars with mileage in Japan are not popular, and if they buy them, it is only for the purpose of reselling abroad or for disassembling and selling parts. But to acquire engines of Japanese production should be with extreme caution. No, you are facing not a bad quality of parts, but rather the opposite. Engineers from leading manufacturers from time to time make changes to the design of their cars, improving it. In addition, Japan supplies its vehicles to various markets - to Europe, the Russian Federation, the United States. And the same model may differ structurally depending on the sales region. Therefore, when buying a contract engine for a Japanese car, you need to consider the following data:

1. Brand.
2. Model.
3. Year of issue.
4. The market for which the car is intended.

When buying a Japanese engine, you need to be extremely careful not to be mistaken in the modifications

How to buy a contract engine

There are only two options for buying - either to independently search for a suitable one, or to entrust a specialist to a company that sells engines. In the first case, you will need a lot of time and money: you will have to travel to Europe or Japan, and for this you need to get a visa and get a foreign passport, if there is none. Of course, the cost of the engine there is much less than in Russia. But oddly enough, in the end, you can get a significant savings. If you decide to act independently, be careful to ensure that the number of the engine is clearly and clearly indicated in all documents on the engine. Otherwise, problems may arise when crossing the border or when registering, if you decide to do this. It will be much easier to buy a contract motor in the company. They have connections with dealers abroad, which will facilitate the search for the desired model. It remains for you to find out the history of the company, how long it has been working on the market, read customer testimonials that used the services, and most importantly, find out whether it will give a guarantee on the engine you bought. If so, for how long.

Some dealers of contract engines can help to choose a more powerful engine that fits your car model.

Contacting such a company, you can count on the help of a competent specialist. You will be offered several options, tell the whole history of the car from which the engine was removed, even provide recommendations on the operation. If you have a desire to put the engine of greater power, they will help you and select the most acceptable option. If you estimate the costs, they will be more than with an independent purchase. But on the other hand, you will be assured that the company’s specialists carried out a complete diagnosis of the engine components, and the faulty ones were replaced. In other words, a good company will do everything to ensure that your purchase does not bring you any disappointment and has served for a long time. The main thing is to carefully read the contract that you sign, and also keep at your disposal an act that describes all the work done by the company. In this case, you have the opportunity to return the engine within two weeks, if you are not satisfied with his work or have any problems with him. This is what a contract engine purchased from dealers means.

Advantages of contract engines

There are cases when the number on the engine of your car was interrupted. In this case, there is a reason to think about installing a contract engine. Also, if your motor requires serious repairs, it may be easier and cheaper to install a contract, rather than repair the old one. You can buy almost a new contract motor, and leave your old one for parts for yourself or even sell. Here you have the perfect compensation for financial losses. And the new one will last for many years without any particular problems, since its resource is quite high. Some motorists argue that the overhaul costs several times more expensive than buying a contractual engine.

Remember - you should only buy the engine with all attachments

It is difficult for them to argue - the full picture is made up of many factors: the make and model of the car, the year of manufacture, the cost of delivery to your region of residence. And most importantly - whether the motor that you purchase was subjected to, repair or replacement of important components. But, arguing logically, one thing can be said - it is better to drive a high-quality engine for ten years, which has never been opened, than five years on a repaired one.
