A serviceable motor (serviceable in the sense that it does not have oil drips) from time to time, for example, at least once a year, still needs to be washed.

A clean motor is less prone to overheating. Dust and dirt can serve as a kind of winter coat, and a very dirty motor is subject to more severe thermal stress. Although the cooling system modern cars designed for heavy loads, and, most likely, will be able to cope, but why should she complicate the work, you ask?

A clean motor is more pleasant and easier to maintain, if only because of the lower risk of getting dirty. Simple operations that most car enthusiasts prefer to do themselves, such as: changing engine oil, changing air filter and spark plugs - all this is much more pleasant to do when engine compartment Your car is clean.

In order to make servicing the car easier, you need to keep it tidy, more about this in the materials:,.

A clean car engine and engine compartment is less fire hazardous. There are a large number of cases when oil smudges, overheating of the exhaust manifold caused ignition of the engine compartment wire harnesses.

So, the engine needs to be washed. The simplest and not so effective method is the use of high-pressure apparatus. A jet under high pressure can easily ruin the hood insulation and destroy all stickers with useful information in the engine compartment, but also peel off the paint on some parts. After such a wash, water is most likely to get into the candle wells and the distributor, inside the housings of electronic relays and other devices, such as a generator or an engine control unit.

Therefore, upon completion of such a wash, all water will need to be removed with compressed air, while removing the connectors of electronic devices.

We recommend using a more gentle washing procedure. To do this, you will need to use special detergents, for your convenience, use aerosol fillers. Wait for your car's engine to cool down and spray the engine compartment. Wait ten minutes and wash off all the dirt along with the cleaning liquid with a gentle pressure of water, for example, from a hose or bucket.

If the motor is hot during washing, then most of the cleaning agent will not have time to corrode the dirt, it will simply evaporate quickly.

More gentle, and, therefore, more acceptable, in our opinion, the procedure for washing the motor looks like this. Spray the cool engine, though perhaps the entire engine compartment, with a spray can of detergent and a couple of dozen minutes. wash everything off with water, a weak stream, or simply watering everything from a bucket.

It can be simply useless to use detergent compositions such as kitchen "Fairy". They only dissolve animal fats, but against engine oil and other by-products of the engine, alas - they are powerless.

After finishing washing the car, rinse everything again with water and, after opening the hood, leave the car with open hood dry in the sun. If it is possible to use compressed air, the drying process can be accelerated. However, while blowing the motor compressed air, it is possible to blow out drops of water to where they will subsequently be completely superfluous. For example, in the same candle wells.

To maintain the paintwork of your car in proper condition, we recommend that you familiarize yourself with the materials:,.

How to properly wash the engine and engine compartment of a car Any motorist regularly cleans his car, as a clean body has an aesthetically pleasing appearance and is less susceptible to corrosion. Over time, all car owners face the question of washing the engine to clean all the dirt that has accumulated under the hood. Opponents of this procedure are reasonably guided by the principle of "do no harm", which is due to the capriciousness of electrical equipment in contact with moisture. But there are much more arguments in favor of washing, it can and should be done, but with precautions. Why Wash Your Engine and Engine Compartment A healthy engine with no oil or coolant leaks needs to be washed periodically for the following reasons: An engine that is free of dirt and grime is not prone to overheating. Dust deposits serve as a heat insulator, creating an unnecessary load on the cooling system. A clean engine is easier and more enjoyable to maintain. Replacing oil, spark plugs, filters or process fluids at a service station with a dirty power unit can cause the master to carelessly treat the car and reduce the quality of its work. A dirty engine compartment is more of a fire hazard. There are cases when oil that appeared on the engine and other parts of the compartment caused ignition due to the ignition of combustible vapors from a spark, an overheated or damaged exhaust manifold, and exhaust gas breakthrough. A clean engine allows you to immediately find the place of the leak and quickly fix the problem without waiting for it to worsen. When selling a car, the probability of finding a buyer faster, having a clean engine, is higher. Preparing for washing the engine Before starting the procedure for washing the engine compartment, certain preparatory actions are performed to prevent the negative effects of moisture on wiring, electrical appliances, and parts that are sensitive to wetness. The procedure is as follows: Disconnect the negative terminal of the battery. Dismantling the protection of the engine compartment. Protection of sensors, connectors and wires with adhesive tape and polyethylene film. A good effect is given by water-repellent aerosols, which process connectors and electrical contacts. Disconnection of parts and assemblies that interfere with access to the engine. How to wash a car engine at home When choosing a detergent for the engine, they proceed from the density of the units under the hood. In simple and relatively old machines, it is not filled too tightly, which allows the use of bottles with a manual dispenser. This design ensures accurate dosing of the product and its economy. For new vehicles with tight engine compartment aerosols are more suitable, allowing you to process all hard-to-reach places. Concentrated detergents are found in automotive cosmetics stores. They are not very convenient to use, but are indispensable for severe pollution, allowing you to get rid of a large layer of accumulated dirt at a time. For washing the engine, it is forbidden to use products intended for the bodywork, due to the acid content that damages metal parts. The use of diesel fuel and gasoline is unacceptable, as it threatens with instant ignition in the engine compartment. See which external engine cleaners do their job better: To thoroughly remove dirt deposits and streaks of process fluids, special detergents are used when washing the engine compartment. Depending on their type, the method of application and preparation differs, detailed in the instructions on the package. It is impossible to wash a hot engine, as the agent on the unit body will dry out. The procedure itself is performed in the following order: After the preparatory work, a detergent is applied to the engine and waited for the time specified in the instructions. With the help of a brush, the most polluted, hard-to-reach and problem areas engine. Washing off the detergent. The operation is repeated until the foam and dirt from all areas is completely removed. Removal of previously installed insulation from film and adhesive tape. Drying the engine with compressed air. Special attention is given to candle wells, contacts and depressions where water collects. Starting the engine and checking its smooth operation. Washing the engine, ignoring the above rules, is dangerous in its consequences, the most harmless of which is the engine not starting due to water entering the electrical wiring connectors. Sometimes car owners do not take into account the significant temperature difference that leads to deformation of the cylinder head. For this reason, washing in winter is best postponed until summer.

Washing the car engine is included in the list of mandatory maintenance work. At the same time, among car owners there is still no consensus on whether it is worth performing the procedure. There are some subtleties that not all car owners know about. That is why it is worthwhile to separately deal with this issue and decide: is it worth it and how to properly wash the engine yourself.

Washing the engine compartment of the car is necessary once or twice a year. At the same time, answering the question why to do this, it is worth giving the following arguments:

1. A clean engine does not heat up, as the dust acts as a body insulator and puts additional stress on the car's cooling system. If you wash it off, the motor will run smoothly, without interruption.
2. if the engine compartment is clean, it is easier to maintain.
3. in a dirty engine compartment, fires can occur from drips of gasoline and automobile oil. For this, an ordinary spark or a breakthrough of exhaust gases is enough.
4. washing the motor is also needed because it allows you to clean the surface power unit locate the leak yourself. As a result, it becomes possible to take action in a timely manner, without waiting for the situation to worsen.
5. Before selling, the motor must also be washed in order to show the potential buyer that it works without interruption. In addition, a clean engine compartment allows him to adequately assess technical condition engine.

How to properly wash your car engine

Do-it-yourself car engine washing is far from that simple procedure as it seems. The fact is that a powerful jet of water can pierce the hood insulation, in addition, water in this case will penetrate into the candle wells, or under the rubber caps on the candles. Also, a strong jet of liquid is able to rip off various covers and attachments located under it.

If you have no experience in cleaning the engine compartment, or you do not know how to wash a car engine with your own hands, it is better for you to contact a professional car wash. They have experience in performing work and special equipment for this.

If you decide to remove the existing dirt in the engine compartment and properly wash the car engine yourself, you should adhere to the following algorithm of actions:

1. First you need to seal all the main components and assemblies of the motor so that water does not get into them. This is especially true for wiring and air filter. This can be done with plastic wrap and tape. It is necessary to seal all factory stickers placed on the engine.
2. Then it is necessary to clean the engine compartment from oil and dirt with a specially purchased chemical composition. To do this, a certain amount of these fluids is applied to the engine. In order for the chemicals to work, you need to wait for the time specified in the instructions and then rinse off the detergents with a jet of water under pressure or steam under gentle pressure.
3. When the washing procedure is completed, it is necessary to remove the protective film from the components and assemblies and thoroughly dry the engine compartment with compressed air. At home, this can be done using a conventional building hair dryer that does not work on full power. If you have a need for such equipment, and you cannot quickly find a hair dryer, you can dry the motor with a vacuum cleaner.
4. The work is completed by removing the resulting stains and streaks with a microfiber sponge or suede cloth.

In addition to following the general algorithm of actions, it is required to follow some separate rules on how to properly wash a car engine. The engine compartment must not be washed too often to avoid corrosion. It is forbidden to wash the engine in a completely cold or too hot state to avoid damage to the cylinder head. Therefore, the engine compartment is not washed in winter, and before starting the procedure, the engine is started and immediately turned off.

It is also impossible to use water with a temperature above +10 degrees. Under the influence of high temperatures, not only engine elements can deteriorate, but also accessories made of plastic. For this reason, before starting the procedure, it is worth clarifying whether it is possible to wash the car engine with Karcher.

Separately, it is worth mentioning that it is advisable to de-energize the car before washing. The battery itself can be washed and dried outdoors. During the procedure, the battery terminals must be treated with a soda solution in a 1: 1 ratio.

How to wash a car engine

In order to find out which product will best perform the function of washing, it is necessary to study in advance specifications one means or another. For example, relatively old cars have an engine compartment that is not too densely filled. As a result, it can only be operated using hand spray bottles. Their design allows precise dosing of the detergent. This makes it possible not to spend a large amount of money when washing the power unit, which is better than washing a car engine from a bucket. New cars with a tight engine compartment are treated with aerosols that penetrate even hard-to-reach places.

Concentrated detergents are available from specialized auto accessory stores, which can be used to remove the most stubborn stains. At the same time, it is worth remembering that when washing the engine, it is strictly forbidden to use those products that contain acids or other chemicals.

Separately, it should be noted that the use of gasoline or diesel fuel when washing the engine is strictly prohibited to avoid fire.

The advantage of washing with steam

The most popular way to wash the engine compartment is to wash the car engine with steam. This method of washing has a number of advantages over other means of maintaining cleanliness in the engine compartment:

• there is no need to use chemical cleaners, which is safe for the paintwork of the engine compartment elements;
• the ability to clean all the elements of the car at once, and not just the power unit;
• production simultaneously with washing, disinfection of the interior and engine compartment, attacks like steam has a high temperature, at which almost all harmful microorganisms die;
• steam cleaning is a dry washing of a car engine, since a car treated in this way can go on a trip immediately after all the necessary procedures have been carried out;
• steam perfectly washes away oil and fuel stains, which makes chrome parts shine;
• steam is able to penetrate into the seams and joints of machine parts, as well as into the folds of the upholstery;
• steam cleaning takes 30-40 minutes, which is several times faster than traditional cleaning.

Washing products

To properly clean the engine compartment, you need to know how to wash a car engine. You need to purchase special products, and other types of cleaners should not be used, as they can cause damage paintwork certain elements of the engine compartment of the car. Separately, it is worth mentioning that the washing equipment used in the washing process (for example, Karcher) should be used only with the car shampoo that is indicated in the instructions for it.

Drying engine

The washed engine compartment and the engine itself must be dried after the procedure is completed with a dry paper towel or rag. At the same time, if after this it is found that there are traces of corrosion on the elements of the engine and the engine compartment, their locations must be cleaned with baking soda and water in a ratio of 1: 1. The washed and processed engine should be started and let it run to check its performance.

conclusions

The car engine needs to be washed, just like all its other structural elements. At the same time, when washing it, it is necessary to follow some rules in order not to damage the power unit and components of the engine compartment. The frequency of washing the motor is once a month and it should be adhered to so that the engine not only looks neat, but is also serviceable. On a clean engine, you can see in advance traces of fuel and oil leaks, and eliminate the malfunctions that caused them in time.

How to wash a car engine and whether it is worth doing it at all - such questions sooner or later arise in almost all motorists. And the answer here is unequivocal - it is necessary to wash. And there are a number of reasons for this.

Washing a car engine provides undeniable pre-sales benefits

Car engine wash. Is it worth washing?

• The first reason is aesthetic. Agree that it is nice to open the hood of your car and see the engine compartment sparkling with pristine cleanliness. Yes and repair work in the engine compartment it is much more pleasant to spend if it is not covered with a thick layer of dust.
• Secondly, a clean engine allows you to determine at a glance the location of leaks of technical fluids. And if the problem is noticed and solved in time, it will save a lot of money. In addition, a car with a sparkling engine compartment will find its buyer much faster. Yes, and its cost, other things being equal, can be slightly higher average price on the market. After all, whatever one may say, most motorists, when buying a car, are guided not only by its technical condition, but also by its appearance. So there is also a financial aspect in washing a car engine.
• Thirdly, timely washing of the car engine allows you to protect it from possible overheating. After all, dirt, fluff and other contaminants that have settled in the engine compartment act as a kind of fur coat that does not allow transferring excess heat from the power unit to the surrounding space.
• In addition, a mud coat is a fairly good conductor of electricity. In the worst case, it may cause problems with starting the engine, and the engine itself will start to work intermittently.
• Do not forget about safety. The engine compartment, as a rule, is quite heavily soiled of various kinds. technical liquids. And most of them are highly flammable. So in this case, you can not do without washing the engine.

That's just automotive manufacturers unanimously declare that it is worth washing the car engine only in exceptional cases. And there is some truth in this, because it often does more harm than that layer of dust and oil stains that have accumulated in the engine compartment.

How to wash the engine?

There is a wide range of car engine care products on the market.

But if you nevertheless made a firm decision to clean the engine compartment of your car from contamination, then you should know that engines can be packaged in a wide variety of containers. Most often, aerosol cans and plastic bottles are used for this, allowing you to spray the cleaner manually. Occasionally, cleaning products are also packaged in glass bottles.

Aerosols and bottles with manual sprayers are, of course, the most convenient when washing a car engine. They allow you to direct a jet of liquid even to the most inaccessible places, which cannot be achieved when using products packed in ordinary containers. On the other hand, glass or plastic bottles without atomizers bribe with their low cost, so if you are not afraid of applying a cleaning agent with improvised means, you may well take a closer look at them.

Although in any case, when washing a car engine, it is more expedient to proceed from how tightly the units are located in the engine compartment of your car. In old or comparatively simple cars the engine compartment, as a rule, is not filled very densely, which makes it possible to wash it with the help of bottles with a manual sprayer. In addition, this design of the bottle allows you to accurately dose the product, which allows you to use it in minimal quantities. But to clean the engine compartment of new cars, it is more expedient to use aerosols. With their help, even in the presence of a large number attachments you can reach the most inaccessible places.

Quite often, detergent concentrates can also be found on the market. It is most often not very convenient to use them, but if the engine of your car is very dirty, then it is easier to use a concentrated product to clean it, which will allow you to clean even heavily contaminated areas at a time.

Please also note that the products intended for cleaning the car body from dirt are not suitable for washing the engine. The fact is that most of them are based on acid, which can damage the metal parts of the engine.

Washing the engine compartment with diesel fuel looks even more barbaric. And although this old-fashioned way is quite effective, there are still more minuses from it. Firstly, after such an engine wash, it will be very difficult to get rid of the smell of diesel fuel. And this applies not only to the car itself, but also to you. And secondly, this method is simply dangerous. Vapors of diesel fuel ignite instantly under certain conditions.

The same thing can happen with gasoline, which some motorists also use to wash their engines. A small spark is enough, which may well be formed due to static electricity, and a fire cannot be avoided. At best, you will have to get off with a little fright, and at worst, say goodbye to the car. Is it worth the risk?

Even before you start washing the engine, you should make sure that it will not be washed with. A strong jet of water can easily wash off the inscriptions not only from decorative plastic covers, but also from attachments that are in the engine compartment. And after all, these are far from all the troubles that a strong pressure of water can create. A powerful jet can break through the insulation on the hood, penetrate into the candle wells and under the rubber caps on the candles. So if you use a mini-sink when polishing under the hood, then only with a minimum pressure of a jet of water.

2. After that, the engine compartment with the selected chemical composition and after the time indicated on its instructions for use, wash it off with a light pressure of water. If after that some parts of the engine compartment still have not got rid of dirt, then the procedure should be repeated.
3. Now it remains to remove the cellophane and dry the engine compartment with compressed air. For this you can use air compressor or a regular household vacuum cleaner. When drying, pay special attention to those places where electrical equipment is located.
4. Now it remains to start the car and make sure that the engine runs stably.

What are the consequences of an improper engine wash?

Washing the engine without following the rules listed above can be very detrimental to the power unit of the car. Quite often, motorists forget that large temperature changes should be avoided, which can lead to deformation of the cylinder head. That is why you should not wash the engine in winter. Yes, and in the summer it is better to wait until the engine cools down.
