An article on how to properly flush a car engine, what to pay special attention to. At the end of the article - interesting video on how to safely wash the car motor.

The content of the article:

The engine is often called the "heart" of the car. And this is no accident. If a person leads an unhealthy lifestyle and lives in mud, his heart function will deteriorate dramatically. The same thing happens with a car. If the driver does not take care of the engine, breakdowns will begin. Moreover, you need to take care not only from the inside, but also from the outside. The motor must be washed periodically. How to do it? What should be considered when washing the engine? Let's figure it out.

Is it worth washing the motor at all?

Almost all car owners ask themselves this question. It should be noted that there is no single answer to this. There are both supporters and ardent opponents of car washing.

For example, Anton Rotov, an engine repair specialist at the service station, believes that the engine should be washed only before selling a car. Of course, if the car has been constantly used off-road or is more than seven years old, then you need to wash the engine. Potential buyers can confuse a dirty engine when they open the hood.

There are also more ardent opponents of engine rinsing. They are convinced that this procedure (if performed incorrectly) can lead to negative consequences, which are much worse than a thick layer of dust and impaired heat transfer.

Others believe that it is imperative to wash the motor, only to do it in professional car washes, where special detergents are used and the workers understand how to do it correctly.

After all, the motor also gets dirty during operation, dirt gets on its moving and stationary elements ( technical fluids, abrasive), which has a negative impact. A thick layer of dirt can cause the engine to overheat, contacts in the wiring connectors can clog (if they are poorly protected), dirt particles can get into containers with technical fluids. In addition, a dirty motor is more difficult to maintain, as it can get very dirty.

Here are the main reasons why it is still worth washing the engine:

1. Aesthetic. It's nice to open the hood of a car and see clean engine compartment... At the same time, carry out renovation work will be simpler.
2. A clean motor allows you to quickly identify the places of leaks of technical fluids. If you find and fix the problem in time, you will not need expensive repairs.
3. A car with a sparkling engine is easier to sell. Moreover, its cost may be slightly higher, since many buyers pay attention not only to technical condition car, but also on its appearance. Therefore, car wash is even financially beneficial.
4. Washing protects the engine from overheating. The dirt deposited on the motor serves as a kind of fur coat that impairs heat transfer between power plant and the environment. This can lead to a loss of car power and an increase in fuel consumption.
5. A mud coat conducts electricity well. Therefore, the engine may run intermittently or not start at all.
6. The engine compartment is usually stained with various technical fluids, which can lead to a fire. Washing will avoid this.

Thus, it is necessary to wash the engine, just do not show excessive fanaticism. Experts advise doing this about once a year. Moreover, it is necessary to wash the motor correctly, because an inept washing can do more harm than the existing layer of dirt.

How to wash the motor

First, we will tell you how NOT to wash the engine. First of all, you need to give up household detergents and detergent powder. They will not be able to deal effectively with the engine oil. In addition, it is not known what is included in their composition.

Do not wash the engine with a car body cleaner. Many of these contain acid that will damage the metal parts of the motor.

You should also abandon the old old-fashioned way - washing the engine with gasoline, diesel fuel or kerosene. Washing the engine with a diesel engine is safe, but pointless. After all, you need to rid the engine of oil and other substances, and not smear all the details in them. In addition, after such a wash, the whole car will smell of diesel fuel for a long time. If we talk about gasoline or kerosene, then this is very dangerous. An arbitrary discharge will cause a fire. Then you have to say goodbye to your favorite car. So don't experiment.

Now in car dealerships you can buy various products for caring for the engine compartment. But there are many factors to consider.

Detergents are packaged in a wide variety of containers. Typically, aerosol cans or plastic bottles are used that allow manual spraying. AT rare cases glass bottles are used.

Hand spray bottles and sprays are most convenient, as you can direct the stream of detergent even to hard-to-reach places. This cannot be done with products that are packaged in simple containers. However, bottles without sprayers are cheaper, so you can buy them if you are ready to apply the substances with improvised means (for example, brushes).

When choosing detergents, you must also take into account the density of the units in the engine compartment of the machine. As a rule, in old and simple cars, the engine compartment is not filled tightly, so bottles with a hand spray can be used to wash it. This design of the bottle, among other things, allows for more accurate dosing and saving of detergent.

In modern new cars, the engine compartment is densely filled, so aerosols are more effective for cleaning it. They will allow you to remove dirt in all hard-to-reach places.

Detergent concentrates are also sold in stores. They can only be used if the motor is very dirty. Then the concentrated product will cleanse it in one go.

Now that you understand why you need to wash the car engine and how to do it, you can proceed to consider the features of the washing procedure.

If you have no experience in this matter, it is better to contact a specialized car wash. You just need to trust the motor wash to really professionals. Many sinks are staffed by students or even high school students. They have no idea how to properly wash the motor.

Moreover, even experienced workers often do not understand the intricacies of washing the engine. On many autobahns, the motor is washed under high pressure. It is strictly forbidden to do this, since a powerful jet can easily break through the hood insulation, water can get into the candle wells or under the rubber caps on the candles. Moreover, a strong jet can wash away the lettering from the plastic covers and attachments under the hood.

You also need to be aware that the employees and management of the car wash are not responsible for any consequences of rinsing the motor. And, as you can see, they can be.

In the best case, the car simply won't start, and I don't want to talk about the worst. You can, however, write complaints and go to court, but this is an extra headache.

Therefore, the choice of a car wash must be taken very seriously.

Better to wash the engine yourself. There is nothing difficult in this, you just need to do everything carefully.

Here is an algorithm for the main actions when washing a car engine:

1. First you need to close all the main nodes so that moisture does not get on them. Take cellophane and tape and carefully wrap the motor control unit, battery, generator, air filter, alarm, electrical wiring and other important components that are afraid of moisture. You also need to tape the factory stickers on the engine with tape, otherwise they may come off.
2. Then you need to process the engine compartment with the acquired chemical composition. Then you need to wait for a certain time (indicated on the instructions of the substance) and wash off this product with water (light pressure). If some places after this still remain dirty, you must repeat the procedure.
3. After finishing the wash, remove the protective cellophane and thoroughly dry the engine compartment with compressed air. In this case, a household vacuum cleaner will help. Places where electrical equipment is located must be dried with particular care.
4. Then you can start the car to make sure the engine is running smoothly. At the end of this entire procedure, you can work with a rag to remove all drips.

This is a general sequence of actions. However, it is important to follow a number of rules:

1. It is forbidden to wash cold or hot engine... Large temperature fluctuations can deform the cylinder head. The optimum temperature is 40 degrees. Therefore, you need to start the engine and turn it off. Also, do not wash the engine in winter.
2. The water temperature should approximately correspond to the engine temperature (+10 degrees is permissible).
3. The battery can be removed during washing, but you can also leave it (previously covered with polyethylene). In this case, the negative terminal should be disconnected. When the engine wash is completed, it is worth treating the battery with a soda solution (in a 1: 1 ratio). This will protect the battery from metal corrosion. Then you need to wipe the battery with a damp cloth and dry it in the sun.
4. Use a spatula or scraper to clean thick layers of dirt. A thin brush will help to clean hard-to-reach places.

If you follow all of the above recommendations, the engine compartment of your car will be perfectly clean. And this will save you from many problems.

Let's sum up

It is imperative to wash the engine and do it about once a year. This procedure can be entrusted to professional washers or you can do it yourself. There is nothing complicated about this, any car owner with hands from the right place can easily cope with this.

Every car enthusiast knows a simple fact - a car will last longer if properly cared for. Perhaps, for those who recently got behind the wheel of their favorite car, this will seem unusual, but for long-term operation of the car, you need to periodically wash its engine. To make sure that such an action is necessary, it is worthwhile to understand why it is important to arrange water procedures motor.

Choosing a sink: the pros

The main reasons why many car enthusiasts decide to wash their engine are very compelling.

1. Motor connectors that are poorly protected tend to accumulate dirt. Such mud deposits, in turn, can lead to the fact that in electronic system a short circuit occurs. And when closing, a variety of consequences are possible - from a blown fuse to a fire.
2. If the oil begins to mix with dirt deposits, and this process continues for a long time, then the machine body in the area of \u200b\u200bthe motor will not be able to fully cool. In addition, a dirty unit overheats much faster, which leads to thickening of the oil and, as a result, engine boiling.
3. On a dirty engine, it is difficult to notice leaks of oil and other fluids, as well as to see the negative consequences of unqualified repairs.
4. Well, of course, the aesthetic component is also important: studying a dirty engine compartment before repairs is not a pleasant activity.

The only tangible argument against washing the engine is the risk of water coming into contact with the vehicle's electrical mechanisms, alternator, battery and starter. If such contact occurs, a short circuit can be the consequence. Therefore, it is important to know how to properly wash the engine of your favorite car in order to get a clean unit to a shine and the absence of any negative consequences.

Necessary conditions for washing the motor

If you have the funds, the best option would be to visit a decent car service, whose workers have a clear idea of \u200b\u200bhow the engine is washed in the car. If the sink power unit you have to do it yourself, then you should thoroughly prepare before directing a stream of water into the engine compartment.

First of all, you need to pay attention to the temperature of the motor - it should not be higher than 40 ° C. If detergents come into contact with a hot engine, it can lead to breakage of the unit head, micro cracks and other malfunctions. But a cold engine is also not the best way: At low temperatures, more effort is required to remove dirt.

The temperature of the water used for washing should not differ from the engine temperature by more than 5-7 ° C.

Once this issue is under control, care must be taken to ensure that all parts of the engine vulnerable to water are protected. To do this, you need to use a plastic wrap, which is convenient to fix with tape. Vulnerabilities include the fuse box, battery, wiring, electrical, and anything that could be damaged by water. It will not hurt to protect the stickers from the manufacturer with adhesive tape. The sensors must be covered with masking tape.

It is important to protect the air intake from entering the cleaning agent, for this you need to close it and put a film on top.

There is one more special point that must be taken into account before proceeding with the washing of the car unit: in order to fully clean the engine, you will have to pay attention to the oil pan. Since this part of the engine compartment is washed from below, it will be extremely inconvenient to clean it in a regular garage. Therefore, in order to clean the pallet efficiently and correctly, you need a room that has a viewing hole.

What to use for washing

When choosing products for cleaning the power unit, it is better to start with the most the best option and give preference to special formulations that are designed specifically to work with the engine. Moreover, the best packaging in this case are aerosol cans or plastic bottles with dispensers.

Some motorists use alcohol diluted in water as a cleaning solution, or diesel fuel... And although it is quite possible to achieve certain success with such a wash, it is worth recognizing that these are not the best methods of dealing with dirt in the engine.

Those drivers who have an idea to tidy up the engine compartment with car shampoo can immediately abandon this idea, as well as from attempts to wash the unit with gasoline. The latter option, by the way, is very dangerous, as it can lead to a fire.

It is important to consider the following nuance: cans are recommended for use when working with an engine modern car... The motor of a four-wheeled friend with experience is best washed using a spray bottle that allows you to accurately determine the dose of detergent.

How to clean the motor correctly

After the power unit has been prepared for washing, you need to apply a chemical agent mixed with water on its surface (1: 1 ratio) and leave for 10-15 minutes. The exact waiting time should be indicated on the package. It is necessary to pause after applying the cleaning solution so that the necessary effect is exerted on the layer of dirt and dust. Hard-to-reach areas can be cleaned with a brush.

After waiting 10 minutes, the engine compartment must be carefully washed, removing the formed foam, and if there are traces of dirt on the engine, repeat the procedure.

The question "whether it is necessary to wash the motor with Karcher" can be answered unequivocally - it is better not to do it yourself. The most correct thing to do in this situation is to entrust such a sink to professionals. This advice is rooted in the fact that such mini-washers produce a jet of water under high pressure that can wash off the factory inscriptions on the unit's components. Moreover, it is quite problematic to protect the relay housing, candle wells and distributor from moisture from getting into it with such a strong pressure. It is good to use Karcher when it is necessary to thoroughly wash the lower part of the car body, but for the engine this cleaning method is too aggressive.

When the engine compartment is free of dirt and oil build-up, care must be taken to ensure that the unit is thoroughly dry. And only when the remaining moisture evaporates, you can remove the plastic wrap and scotch tape.

On cold winter days, cleaning the engine compartment will have to be postponed. At sub-zero temperatures, the unit after washing will not be able to dry out qualitatively, which is fraught with malfunctions and problems with starting the engine.

It makes sense to wash the car in winter only if there is a warm, dry room equipped with an inspection pit (for cleaning the oil pan), where the car can easily fit.

Amateur video:

It is not difficult to draw a conclusion from the above information: it is possible to wash the engine compartment, but this will have to be done very carefully, since if the cleaning process is negligent, the unit may not start. Therefore, it is important to carefully select chemicals and strictly follow the rules for safe engine washing.

Washing the engine compartment and engine for many motorists can be both a forced procedure and a desire to keep the car as clean and serviceable as possible. In the first case, there is an urgent need to wash engine oil and other technical fluids from the engine, which have formed drips due to various malfunctions. Also, the engine often becomes dirty after repairs.

In the second case, the engine is washed to maintain cleanliness and remove the so-called mud "coat". According to a large number of owners, a layer of dirt on the motor impairs the efficiency of heat removal from the engine, and can also cause malfunctions of electrical equipment, etc. As for the process of cleaning the engine from dirt itself, you can use the services of a car wash to remove dirt with a jet of water under pressure, as well as more delicately wash the engine yourself.

At the very beginning, we note that it is optimal to wash the engine in dry and warm weather, which allows you to quickly get rid of high humidity under the hood after washing. To remove various engine contaminants, special formulations... Also used are "mild" acid-free car shampoos.

Note that a kitchen dishwashing detergent is quite suitable for washing the engine at home. Such products remove grease well, and also do not contain aggressive components that can harm plastic, rubber and other elements in the engine compartment.

In addition, you will need a regular plastic bag or foil, a sponge, rubber gloves, a rag and a soft bristled brush. It is not recommended to use hard brushes, especially with metal bristles, as there is a risk of scratching soft surfaces. You should also have some baking soda on hand to clean oxidized electrical contacts.

How to properly wash the motor

1. Allow the engine to cool down before washing, if it warms up to operating temperatures. Failure to comply with this requirement may lead to the fact that under the jet cold water there is a risk of rapid cooling and subsequent deformation when heated.
2. The next step is to disconnect the terminals from the battery. As for, then it is necessary to clarify the location rechargeable batteries on a specific model. It should be added that often the batteries of hybrids are located in the rear of the car, so washing the engine on a hybrid car in this case is not dangerous.
3. Further, certain elements in the engine compartment must be protected from moisture. This will require the above polyethylene and foil. The engine air intake is closed first. For this, a package is perfect, which should additionally be wrapped with tape or electrical tape for secure attachment.

   Always remember, water ingress through the duct can cause serious damage! Also, the ignition coil and other accessible contacts, terminals and elements of the electrical circuit are closed without fail. In hard-to-reach places, foil should be used to protect against moisture ingress.

4. Then you can start preparing the engine cleaning solution. For this, 1 liter. about 20-50 ml of warm water is added. detergent. As for car shampoos that are used for washing the body, their use is not recommended due to the possible presence of aggressive reagents.
5. It is necessary to start washing the engine by slightly wetting the surfaces with water. Water can be sprayed with a brush. After that, the sponge is moistened in the cleaning solution, after which you should start wiping the dirty surfaces. In areas that are difficult to reach, a brush or paintbrush should be used. The parts covered with the solution are left for 5 minutes.
6. If the motor has oil stains or streaks, then such dirt can be removed with a toothbrush. It should be added that this method is suitable for both plastic and metal surfaces. Another way to remove greasy stains is with a solution of kerosene and water. This solution is not desirable for plastics and painted surfaces. Kerosene is applied with water using a soft cloth, after which the surface is wiped off and immediately rinsed with a small amount of water.
7. The final stage is rinsing the engine after washing. Care should be taken during this process. Minimizing the total amount of water entering the locations electrical contacts and electrical equipment (even taking into account that the elements are covered with bags and foil), will reduce the risk of unwanted moisture penetration. Try not to rinse off the detergent with a heavy hose stream or use equipment that supplies water under pressure.
8. Upon completion, you should make sure that there is no need to re-clean the internal combustion engine and individual sections in the engine compartment. If necessary, complete or partial washing should be repeated.

Drying the engine after washing

The engine must not be started immediately after washing, as the engine must be dried. Ordinary paper towels work well for drying the unit. With their help, it is necessary to remove water as efficiently as possible. After that, you can remove the protection in the form of bags and foil. Make sure no moisture gets on the protected items. If water drops are found on the connectors and electrical contacts, they should also be thoroughly dried.

Finally, we add that in case of detection of corrosion and oxidation of the battery contacts, you can use a solution of baking soda and water in a 1: 1 ratio. This solution is applied with a toothbrush and allows cleaning of the indicated parts. Then you need to wipe the cleaning sites with a cloth dampened in water, after which you will need to completely remove the remaining moisture with a dry paper towel or rag.
