On the pages of our site, we try to raise only the most popular and current issues, giving them as full of answers as possible. The topic of buying a car, perhaps, can be called one of the most popular, and if we talk about car vehicles, then at all the top theme.

Somehow, we already talked about what you need to pay attention to when buying, etc. Today, the topic, in principle, similar, just this time we will talk specifically about how to check engine When buying a buckle car.

The greatest difficulty when checking the engine is that, in contrast to or, its condition cannot be determined "on the eye". Externally, it can be clean and tidy, but inside it can be waiting for very large troubles. How to check the motor when buying a car and not "get on money," we will now tell you.

Indeed, no one will give you inside a foreign motor, and this is normal, nothing can be done about it. However, it is not necessary to be upset, because there are certain tricks and secrets that allow you to determine the state of the motor with a very high share of accuracy, which allows you to understand this car to buy or not. Specialists STR and experienced motorists know all these secrets, well, of course, "overbugs", to whom it is not known about the cars. But how to be when such a specialist is not "at hand" or his services are indecent expensive? Everything is elementary, just enough to know where and what to watch!

Engine check when buying a car: Useful tips

The first thing is that you can never say the car to the seller, this is what you are "zero" in cars and engines, in essence. Either do not speak anything at all and keep a mysterious silence, or create a look that they seek so much engines that I don't fit the "Eternal Engine" ... Speak exactly, keeping calm, in no case show your joy from what he seen or heard You need this most "poker face" - a person deprived of emotions. Make sure how the seller, verbia or evaporation from a direct question answers your questions - explicit sign "Dark past" machine. Pay attention to how the machine's master responds to your inspection allows you to watch everywhere or go somewhere.

Engine check: Visual inspection of the procession space

Engine cleanliness. Ask to open the hood and produce visual inspection Engine, guided by certain criteria. If the motor does not work, pay attention to the presence or absence of oil traces. If "threw" know somewhere "zaplinivit" gland or gasket. It is difficult to call a big misfortune, but if you think logically, the untidy engine and the untimely owner's reaction on the projected gaskets says that the owner is slurry or irresponsible. If this is the case, then where the warranty, which was carried out in a timely manner and oil, as well as other consumables changed on time, and this is already a hint of "killed motor." Although, it is only an assumption that is only assumptions, to make a specific conclusion only on the purity of the motor - not correct. You can simply determine the state of the motor without special equipment, it is in this small nuances that will eventually indicate that with the motor and in what condition it is.

On the other hand, the engine is perfect cleanliness, also does not promise you anything good. The fact is that it is not a fact that this cleanest motor yesterday was not all in oil and other mud. Modern chemistry for car wash and the engine is creating miracles, and the fact that it has just been dirty, after 15-20 minutes will radiate crystal purity. In the first case, with a dirty engine that the owner demonstrates you, you at least see what you buy and initially prepare yourself for what you have to spend money on repairs. Moreover, the sellers of such "tired" motors are usually ready to give in price so that you change the glands, gaskets and other seals. Therefore, in this case, the reason to think, perhaps under the mask of purity, is hidden by the order "tired" motor.

Oil condition. Open the cover, it should be clean, and the inner part of the case, which will be seen from the neck, should not have a plaque or dirt. The oil must be clean, Black Maslice says that the oil has changed long ago, so you will have to fork out here. And it is not known how much the owner traveled on this "black". Although, on the other hand, when buying a car, it is like a tradition, so it is not worth upset because of the upcoming oil replacement.

If oil is foaming, it may say that water gets into it. Seeing such a phenomenon further check engine No longer makes absolutely no sense. To finally "put the cross" on this car, get the engine and watch what will happen if the spray will fly out of the neck, the assumption is true, you are trying to "hang" the car with a motor that.

If all of the above is in order, continue the engine check. Ask the owner of the car to start the motor, open the hood and listen to the motor, and also watch it works. I will say what should not be: vibration, shaking, knock and uneven work, all this is not a good engine. If the motor is gasoline, and works like a diesel engine and when it is podging it "throws and turns", "we conclude - something is wrong with Motigl.

In the question of how to check the engine, the exhaust pipe plays one of the keywords

• We continue to inspect the engine head. We go on the side of the exhaust and evaluate the color and loaf of the exhaust. Something similar happens when you breathe in the cold. The exhaust color, as well as its consistency, should be transparent.
• If the exhaust is visible white smoke in the form of a couple, it can talk about the burned strip or not tightness in the cooling shirt.

Important forhanging: If you check the engine in winter, then the thick smoke from the exhaust can be the result of banal evaporation (condensate) when hot air falls into the cold environment and forms steam. Something similar happens when you breathe fresh frosty air ...

• From exhaust going black Smoke - or injector, this is at least. In the worst case, the motor can be sought more serious, problems with piston group, Nagar in the cylinders and the need to separate the engine. In general, in any case, seeing the "black" thank the owner for the demonstration, we wish successful sale And go, not turning around. It is better not to risk and searching the car without Chernuhi.
• Smoke blue - says that. In this case, all the same as with the black smoke - we refuse the deal and go further.

Ask to give the Gat and listen to how the silencer works. Work should be smooth, no "chopping and shooting" should not be. Carefully attach a hand to the exhaust, and appreciate whether there is pressure in your hand, if there is no pressure or it is very insignificant, then exhaust system Has a place.

In more detail about how to determine the status of the engine By color exhaust.

Engine check when buying a car: the final stage - a trial check-in

If all the above tests of the engine you liked the car went successfully, all you have left - check it in practice, that is, ride. The very first thing that buyers will be neglecting buyers are too short test drive. Most often, everything is limited to short plots on the automotive car, and this in order to understand what the "beast" in front of you is very often not enough. If the motor has shown well on a short distance, and the car is still interesting to you, ask the owner to drive 10, promise to compensate for consumption and time costs. Believe me, it's better to spend money now than to break your head over the question where to find a good motorist. During the ride, turn off the music and all that can drown the sound of the motor, instead listen to the sound of the engine with an open and closed window, ask the owner a little accelerate, experiment with a sharp acceleration and see how the car behaves. Expand the car to hundreds and more (if possible, and does not contradict) and see if there is no jerks, what kind of sound does the motor, there are no extraneous noise, knock and other "left echoes".

When the trial check-in is completed, raise the hood again and there are no fresh sublists, and whether everything remained. If after the trip you saw the hint of the leakage, while the motor itself is clean and beautiful, most likely it is the second case when the motor washed to shove the car. However, if all other items when checking did not have any suspicions, then it is possible that this place of leaking oil does not constitute anything terrible and for a small discount you can agree to the purchase of this car. If the engine behaved inadequately during a test race, and after you saw a lot of oil traces, refuse to buy, pay the cost of gasoline and continue searching, this is not your car, it will buy the car that you need repair, and not a means of movement.

By purchasing a car with mileage, it is necessary to take a very checkered for its assessment before purchasing at the inspection phase. The main feature of the used car is that the former owner does not carry any warranty obligations to the buyer. Therefore, it is recommended at the stage preceding the acquisition of the car, to reveal all possible disadvantages as much as possible so that they do not give to know about themselves at the moment when it will be your property. As a rule, the first thing the buyer studies how the car looks outwardly, on the subject of tinted, etc. But without a well-working engine, a beautiful body of special value is not at all. So, it is necessary to look under the hood of the car being purchased.

How to check the engine when buying a car

The very first and, perhaps, the main thing is not a word that you are weakly meaning in car engines. You need to say nothing at all and with a smart face mysteriously keep silence, or to prevent a guy motorist, which in his century did so many engines that he can already design breakthrough innovations with tied eyes. Speak measured, clearly, be calm. Never express joy if you heard something expected. You need to wear a so-called unperturbed mask, absolutely without emotions.

Analyze all seller's responses. If he begins to "pour water" or to water from the answer, it means that it is clear something wrong, and in the past there are some "sinners" relatively this car. Pay attention to the seller's reaction when you examine the machine you. Lee allows him to look everywhere where you are pleased, or on some places trying to distract you and translate to another topic.

What you need to look in the engine

For inspection power aggregate Acquired car you will need:

- working gloves;

Pure rag;

White list.

So, proceed to the inspection.

1. External inspection

Open the car hood and look around the whole motor compartment. Look for oil spots and waste - these are the first signs of engine malfunction. Even small signs in the future can turn into big challenges associated with oil leakage. Especially pay attention to the areas around and the distributor.

The causes of the fluthers can be hidden in the protected gaskets, rubber seals and loosely adjacent clamps on the hoses. The next reason for oil flips is a poorly adjacent cylinder head cover. Well inspect the place of the junction and make sure it is clean from the oil and sealant. Even if the seller brought the engine in advance to normal, it still might miss something. Feel free to expose!For example, testing the engine malfunction can traces on the hood from the inside, inspect it more closely. If scratches are visible on bolts and nuts, even minor, it means that the motor has already opened anyone, and this is clearly not good. But it's good if you were notified that the engine was scheduled for recently.

2. Check the condition motor oil And Tosola.

Oil Check the dipstick, toosol - just unscrewed the lid expansion tank or radiator. The oil should be transparent, without visible impurities and shallow shavings, not too viscous and not to have incomprehensible smells. At the diploma should not be either outsider or divorces. Bubbles in oil - the first sign of leakage, and this is a very serious problem. In the case of coolant, the air appearance in it means that it is dried directly into the engine. And the reasons for this are two: either the gasket was tested, or the block head cracked, and this is completely unacceptable. Tosol is a caustic liquid and can damage piston rings, which will later cause irreparable damage to the entire engine.

3. Cover of the oil refining neck

Inspect the lid outside and inside. Under it or on the throat should not be foam or white climb. The presence of the latter clearly signals that Tosol got into the engine. And what will happen in the future with the engine, we have already spoken in the second paragraph.

4. Candles and rubber elements

Hoses and seals should not be damaged, even small cracks are unacceptable. If under the hood dirty and dust, wear gloves, do not be lazy, and with the help of a cloth, wipe all the nodes and inspect them. Soased smoking can hide many defects. If you can, unscrew the couple of candles, you can learn a lot by their appearance. If they are in order, then they will have a thin layer of light grayish or yellowish raid. Permissible light wear of the electrode. If a crack appeared on the surface at least one candle, then the engine will work with a knock. If there were abundant light sediments on candles - the oil is chosen incorrectly.

If the central spark plug electrode was melted, it may indicate many problems, ranging from early ignition and low-quality fuel to problems with valves and ignition distributor. The formation of solid sticking, according to the type of glaze, which consists of soot, or strong wear of the electrodes mean that the oil used or fuel has been with numerous additives. Grounds serve as an indicator excess oil in a lubricant system and serious wear piston rings, cylinders and guide valves. Nagar on them says about the poor formation of air fuel mixes or clogged air filterwhich requires replacement.

Engine check in

1. Run the motor and jam a little on the spot

When starting, it should not grind and publish other extraneous sounds. The engine must start with the first attempt, despite the fact that he is warm and what weather conditions "overboard". It should work without interruption, absolutely smooth. If the motor began to pull, extraneous vibrations are observed, the rhythm is knocked down, the conclusion is one - the troit engine. So, some of the cylinders stopped working. The reason may hide in faulty system Ignition, bad work of some of the candles, re-entered the fuel mixture or burned piston. In any case, discuss this problem with the seller. Count how much repair it will cost, and knock a couple of times more for the car.

2. Check the instrument readings

With a warm engine running, the arrow of temperature sensors and oil pressure should be within the normal range, ideally - in the middle position.

3. What smoke goes from the exhaust?

If, when the power unit is started from the pipe, it went abundant white smoke, but soon completely disappeared, then it is not necessary to worry at all: it is most likely simple condensate. If smoke never ceases to leave the pipe, then by smell and color you can quickly diagnose the problem. If smoke is white or has a slight squint, which is quickly dissipated in the air, leaving a sweet odor, is that there is Tosol in the car motor cylinders.

Clearly blue or sIZY smokewhich can also have a whitish shade hanging on a light lilac or gray haze in the air means that oil seeps oil into the combustion chamber. If the car "shines" with such surprises, it is better not to risk closing your eyes, for the repair can do it very expensive. And finally, signals that the air-fuel mixture burns inefficiently. The reasons for that are several faults: focusing air jets, depressurization, malfunction in the lambda probe and. The consequences in this case are such that the engine is worn much faster, and the toxicity of the exhaust becomes beyond.

4. Test drive

If all of the above testing you liked the car passed with a bang, then it remains only to ride it. The first error, which is carried out by buyers of used cars at this stage, is long. Often they are limited to a short trip around the bazaar, but this is not enough to understand in full, what car rolls. If the car engine has surpassed all your expectations on a short distance, ask the seller to drive a few more kilometers. Agree that you compensate for consumption and temporary costs.

It is better to check it right now, the later token on the faults not identified in time, breaking his head over the question, where to find a good motorist cheaper. Focus on the sound of the motor, do not turn on the music and everything that can drown it. Listen to the engine with open and closed windows, turn away, experiment with sharp accelerations and watch the behavior of the car. Spoke up to 100 km / h or more if the rules allow roadAnd in touch, there are no vibrations and jerks, as the engine sounds, does not publish outside noise, knocks and other annoying and abnormal.

5. Repeat diagnostics of the motor

Upon completion of the test test drive, look again under the hood and check if it did not appear and everything remained as it was before arrival. If, after the trip you were embarrassed, a certain hint of the leaning, but the engine at the same time clean and looks good, most likely, it's just a move of the owner to sell faster car - He washed the motor. But if other items do not embarrass you, then this place of facing oil is nothing terrible, and for a small discount you can safely buy a car.

If the engine drove during the passage, as an unbridled stallion, and after spoiled the mass of oil flips, then give up the purchase of such a car. Pay for the cost of gasoline and continue to search, because this car is not for you. This car will acquire the one who loves to repair, and not ride.

And summarize. If you are not enough of all of the foregoing, or you doubt your abilities and opportunities, take a person dismantled or go to the service station and order a comprehensive engine check. Thus, you will protect yourself and minimize the likelihood of buying a car with a "driving engine."

Find the dipstick to measure the machine oil level, pull it out, wipe it with a clean cloth and insert it back. Pull out it again and look. If the oil is black (for the engine it is normal), excessive oil is possible or an infrequent one. Another feature of poor service can be a nagar covering the dipstick.

Unscrew the lid where the oil is poured, and enclosed the flashlight inside.
Inside there should be no huge pieces of fuel oil, dirt, etc. If this is the case, it means or the oil was used base, or the engine often overheated.

Many cars, especially with a four-cylinder engine, have a toothed drive belt, which must be replaced at a certain interval - usually between 100-160 thousand mileage. It is usually difficult to check its condition, because the drive belt is closed with protective coatings. Although sometimes dealers put a record with information that indicates the date and kilometer when the belt has been replaced.

Blue smoke When starting, it may indicate that there are problems in the engine. Black smoke means that the engine consumes too much gasoline - possible problem With fuel injection. White smoke with a sweet smell of the exhaust pipe, even when the engine roars on the full coil, can point to a bad cylinder head laying. Usually, there should be no smoke at all. (A diesel engine may have a small black smoke when cold start is normal). A small amount of steam and water condensate dripping from the exhaust pipe is allowed.

Must not be strong noise From the engine. By the way, a crash or roar of cold start - one of the indicators of bad maintenance. Crushing, rattling, and other noise indicate excessive wear of the inner parts of the engine. The whistle can be caused by the helper of the drive belt. It should be noted that diesel engines are always more noisy.

Video on the topic

Engine modern car It is a technically complex unit. Therefore, various unforeseen breakdowns can happen to him. To always be confident in your abilities when deciding, you should know the reasons possible faults and their removal methods. One of the most frequent problems - the impossibility of starting the engine, i.e. Violation of the ignition system.

You will need

• - control lamp;
• - transport;
• - screwdriver;
• - key to 13;
• - Candle wrench.

Instruction

Check on the contact dispenser the gap between the contacts. Adjust it, for this, connect the control lamp to the "mass" and to the "cam" low voltage. Turn on and check the crankshaft until the contacts are closed. In this case, the lamp should be ground.

Take a thin wire and fix the position of the slider relative to the case. Continue to rotate the crankshaft until the warning lamp lights up, fix the position of the slider. Uzb (contact interruption angle) must be within the marks measured by the transport: for the classics of VAZ - 55 ° ± 3 °, for AZLK 2141 - 50 ° ± 2.5 °. Adjust the gap for this angle.

Check the centrifugal ignition timing regulator. Its work can be impaired as a result of the weakening of the springs, which are designed for tightening 2 of its weights. Adjust their tension.

2. Check the condition of motor oil and antifreeze

Oil Check the dipstick, toosol - just reloading the lid of the expansion tank or radiator.

The oil should be transparent, without visible impurities and shallow shavings, not too viscous and not to have incomprehensible smells. At the diploma should not be either outsider or divorces. Bubbles in oil - the first sign of leakage, and this is a very serious problem.

Engine check in

1. Run the motor and jam a little on the spot

The starter at startup should not groke and publish other extraneous sounds. The engine must start with the first attempt, despite the fact that he is warm and what weather conditions "overboard". It should work without interruption, absolutely smooth. If the motor began to pull, extraneous vibrations are observed, the rhythm is knocked down, the conclusion is one - the troit engine. So, some of the cylinders stopped working. The reason may be hidden in a faulty ignition system, poor operation of some of the candles, re-entered the fuel mixture or a rotten piston. In any case, discuss this problem with the seller. Count how much repair it will cost, and knock a couple of times more for the car.

And finally black smoke Signals that the air-fuel mixture burns inefficiently. The reasons for that are several faults: air jackets, depressurization of nozzles, malfunction in the lambda probe and air flow sensor. The consequences in this case are such that the engine is worn much faster, and the toxicity of the exhaust becomes beyond.

4. Test drive

If all of the above testing you liked the car passed with a bang, then it remains only to ride it.

The first error, which is carried out by buyers used cars at this stage, is a short test drive. Often they are limited to a short trip around the bazaar, but this is not enough to understand in full, what car rolls.

Thus, you will protect yourself and minimize the likelihood of buying a car with a "driving engine."

Buying a used car - acquisition for your own fear and risk. The car is a device consisting of a variety of vital and interconnected parts. A breakdown of one of them can occur unexpectedly, and the cunning is that it can not be noticed immediately and react on time. In the meantime, the existing breakage can provoke a breakdown of other parts dependent on it. And so the car is becoming less and less efficient - junk, climbing.

The heart of any car is its engine. It is on him that the burden of the life of the "iron horse" lies. And it is the engine most often suffers from breakdowns.

But when buying a used car, it should be understood that his "insides" in perfect condition will not be, no matter how deceptive his representative exterior appearance. Many drivers argue that after some time after the purchase, breakdowns and countless repairs begin, whose history sometimes lasts for quite a long time. But there are exceptions. Therefore, before purchasing a car, it is worth checking its engine.

The algorithm of action when checking the engine ...

1. Look under the hood. The appearance of the motor should issue itself. Neat appearance Will say that the motor was cared for a motor, followed its technical health. Dirt and oil leaks on the motor should be touched on disappointing conclusions. The likelihood that the motor was specifically cleaned in order to better present it and give a more trade look, Mala, but still there. Most often, the unscrupulous seller will not bother with extra actions. Therefore, it is necessary to pay attention not only to the appearance, but also on the quality of the engine work.

2. Evaluate bolts and nuts. The faces and threads should not be torn. It is for this external factor that one can judge the amount and quality of repair to which the engine was subjected. Moreover, the repair of the engine was performed, apparently, amateurs or self-taught. What they have been played out there - it remains only to guess. The death of this engine is a matter of time.

3. Verification of candles. To do this, one candle will be filled out of the car. The presence of a black plaque on it should push the corresponding conclusions. This means that the oil falls into the combustion chambers and the caps came into a malfunction. Check the caps can be in color smoke from the exhaust manifold. For this you need to start and warm the car. If smoke comes black, then, respectively, the caps have long been time to retire.

4. Exhaust gases. When the engine is cold starting, it is possible to diagnose the integrity of the gasket. To do this, we need to substitute for a few seconds hand under the exhaust pipe, after which the palm sniff. If it smells like Tosol, this indicates that antifreeze is already falling into the combustion chamber, and therefore the gasket is already far from the battle as before.

If the exhaust pipe go smoke Saturated white colorThis suggests that cooling fluid falls in the combustion chambers. This is also not very good. That faulty piston system, Sizaw's smoke says. The "healthy" engine will give a transparent smoke or light gray. Any other rainbow colors will testify only to serious problems with the engine, so the decision to buy such a car is yours.

5. Engine start. This is one of the most correct ways to check the health and quality of the engine. The motor must start within a pair of seconds. At the same time, its launch should not be accompanied by foreign noise, Moreover, a mechanical sound.

6. Engine warming. Another sign of engine malfunction may be the fact that it does not heat up to optimal temperature. This in itself is not good, but to understand whether the cause of the problem is the problem, you need to look at the level of coolant. If it falls and air bubbles are formed on it, this indicates a malfunction of the motor - one of the cylinders cracked. Naturally, the engine is faulty, and therefore ride on such a car - to expose oneself.

Perhaps these are the basic ways to quickly check the engine on malfunction and problems in its work. Buy a car with a faulty engine - this is a voluntary solution. Some it will give the opportunity to bring down the price of the car, but to repair the engine own forces, saved funds.

So from the flaws, too, you can make an advantage. At least now you know how to check the engine when buying. It is worth remembering that used cars will always have some small (or even very) malfunctions. If you want an absolutely good car, then it is better to dig money and buy a new car from official dealer. It, of course, can also have malfunction, but they are obliged to eliminate the warranty.
