Does the engine compartment of a car need to be cleaned?

Hello, it is generally divided into two cases:

1. If the engine does not leak oil, and there is only dust and dust on the surface, then it is okay not to clean, and there is no harm to the engine.

2. If the engine is leaking, then it is best to clean it regularly. Engine oil leakage is common is the valve cover pad leakage, the leaked oil will adhere to the entire engine, the oil is easy to stick to the dust, dust and mud and oil mix, after the high temperature baking of the engine, will form a very thick layer of sludge.

Because the sludge is corrosive, if it is on the engine line or rubber pipe, it will corrode these parts, causing the line and rubber to deteriorate faster, so it is best to do a cleaning. It is best to clean the engine compartment in a professional shop, because they have a special cleaning agent, and the cleaning effect is better.

The engine compartment is the one that needs to be cleaned, and the cleaning steps:

1. First of all, let's use a blow gun to fish for dust in various parts of the engine compartment, including some dead corners, so as not to miss places;

2. After that, take the second step, which is to remove the oil stains in the cabin, and the part that has not been blown off before;

3. Mix the engine cleaning liquid with a certain proportion of water, then dip the brush with a small amount of mixed liquid, and use it to wipe the oil stains on the engine and the places where the dust gun has not been cleared in place;

4. After that, you should dispose of the residual cleaning solution just now, and you can use a rag here;

5. Then blow it with a dust gun to blow the place where the rag can't be wiped; Start the engine and idle it to let the engine heat dry off any remaining moisture.

The engine factory should also be cleaned and maintained at a graded level, so as not to produce too much dust, which will form oil quality. This leads to an increase in temperature, so wash it regularly.

Of course, it needs to be cleaned, otherwise it will be full of dust and oil.

Steps to clean the throttle:

1. First of all, you need to remove the car key, open the hood, and find the throttle valve of the engine. 2. Use a flat-edged screwdriver to remove the air filter and intake pipe, and unplug the electric socket on the throttle; Then use a hex screwdriver to unscrew the three hex screws on the throttle (be careful with this step, be careful that the screws "play missing"). Once the screws are removed, the throttle can be removed and the engine intake is plugged with a dry rag to prevent dirt from entering the engine.

3. First see if the throttle is black or not, and then spray the detergent, the dirt will slowly dissolve, then you can wipe it with a paper towel, spray the detergent again, the throttle will become clean and beautiful, and then you don't need to wipe it with a paper towel, so that the residual detergent will be retained on it. 4. Reverse the disassembly and assembly sequence and reset them one by one; Finally, turn the key to the ignition (don't activate) and turn it off after 5 seconds, which is a procedure for "initialization". Precautions for cleaning the throttle:

The frequency of cleaning the throttle has a lot to do with the habits and environment of the car. If there is no unstable idling, engine shaking, a significant increase in fuel consumption, and weak acceleration, there is no need to clean. It is not too late to clean the above situation, carbon deposition is a slow accumulation process, and there will be no serious failure directly, so pay attention to the condition of the car at ordinary times, and repair it in time if there is a problem.

Extended Information: Reasons to Clean the Throttle:

Every time the cylinder works, it is first injected with fuel and then ignited, and the ignition will be cut off immediately when the engine is extinguished, and the gasoline sprayed by the working cycle can not be **, but can only be attached to the intake valve and the combustion chamber wall. Although gasoline is volatile easily, the wax and gum in gasoline remain, and over time, the wax and gum in gasoline accumulate thicker and thicker, and carbon deposits form when they harden after repeated heating.

Cleaning the engine For a vehicle that is in normal motion, the engine compartment needs to be cleaned after a long period of use. However, it should be noted that when cleaning the engine compartment, it is necessary to first turn off the engine and turn off all electrical appliances to allow the engine compartment to cool down sufficiently. Remember not to wash at high temperatures.

At the same time, it is not recommended to flush the engine compartment with a high-pressure water cannon, since now there are various electronic components in the engine compartment of a car. Although these components have different waterproof measures, if the electronic components come into contact with water, it can cause a short circuit or even damage to the engine components in severe cases.

The general steps for engine clearance are: the first step is to turn off the engine and wait for it to cool down. The second step is to wrap the important electronic components in plastic film to prevent moisture from entering.

The third step is to carefully spray a professional engine topical cleaner into every corner. The fourth step is to wipe every corner with a sponge. Finally, use a hair dryer to dry the wire joints.

Hidden dangers that are not cleaned engines:1. During driving, the engine will produce grease, and the engine will run at high temperature for a long time, which greatly increases the probability of spontaneous combustion.

2.Dirt on the surface of the engine can affect heat dissipation, causing the cabin to be too hot. If regular maintenance is not done, it will affect the service life of the engine, accelerate the aging of the internal parts of the engine, and lead to a series of problems.

The engine compartment needs to be cleaned, and the following lifting years are relevant information: 1. In fact, the maintenance of the engine compartment is more important than the cleaning of the exterior of the car, because the engine compartment has dirt, and with the increase of the age of the car, it will affect the driving safety of the car. Therefore, the cleanliness of the engine compartment also determines the safety of the vehicle.

2. The surface of the engine is covered with dirt, which will affect the heat dissipation of the engine, resulting in the temperature of the engine compartment being too high, which will affect the service life of the engine on the one hand, and accelerate the aging of the internal parts of the engine compartment on the other hand, such as the thread smile and regret bundle, which will constitute a potential safety hazard. 3. In the process of using the car, a thing called sludge will be produced on the surface of the engine, which greatly increases the probability of spontaneous combustion of the engine. At the same time, it is not easy to find problems on the surface of the harness.

<> "Does the engine compartment need to be cleaned?" Presumably, many riders don't know this problem, and even think that it's covered anyway, and it's the same whether it's washed or not! More car enthusiasts who go to the car wash in confusion will not be recommended to clean the engine compartment, and they don't know how to start.

So today, let's talk about whether there is a need to clean the engine compartment and how to clean the engine compartment.

Generally speaking, the car is only 3 years old cars do not need to be cleaned, it depends on the car environment, if you often drive in dusty areas, the new car is driven for two or three years, and the engine compartment is pasted with a layer of "film", then it needs to be cleaned. Cars that are 4 to 5 years old are also in need of the situation, depending on the situation; For cars over 5 years old, it is recommended to focus on the situation in the engine compartment. In addition to the engine compartment, except for the engine engine, gearbox, and battery, other parts are more or less plastic and rubber; Plastic and rubber are relatively easy to age and damage materials compared to metal parts, not that there is no dust in the engine compartment does not need to be cleaned, we usually add oil, glass water, lubricating oil when we are not careful, filial piety will overflow, these things will more or less corrode the parts in the engine compartment, and the accumulation will accelerate aging.

Although there is no change on the outside, or only a slight change in color, but it has actually affected the performance of the car, and the needle-like appearance is one ring after another, the first is the increase in fuel consumption, in addition to the decline in heat dissipation performance, abnormal noise and other problems one after another, the most serious may lead to spontaneous combustion of the car. Although there are generally no extreme consequences, it is very unfriendly to simply increase fuel consumption for no reason, so it is necessary to keep the engine compartment clean.

Let's talk about how long to clean and how to change the cleaning problem, the above more than 5 years old car is the object that needs to be taken care of, but it does not mean that you have to wait until 5 years to clean, after all, the aging of the car is a process, are accumulated bit by bit, in order to maintain the best car condition, it is recommended to deep clean the engine compartment once a year. The easiest way is to go to a car wash or 4S shop. It's also very simple to do it yourself, because all parts of the engine compartment are waterproof, so you can rinse it with an ordinary water hose, wipe it when it should be wiped, and it won't take much time to get it done.

However, it should be noted that do not use high-pressure water guns, steel wool balls, violent pulling, etc. to clean the engine compartment, nor can it be cleaned when the engine is not completely cooled, otherwise it is just doing you a favor!

The above is about the maintenance knowledge of the engine compartment, the car wash can not only wash the appearance, the engine compartment is also a very important thing; Only by taking good care of the car in all aspects can you maintain a good car condition, please give the car a deep clean regularly
