What should I do if the car engine gets water?

What to do if the engine is flooded is as follows:1. If the water ingress into the engine is not serious, but only some water enters from the air filter, then only the water vapor on the air filter, cylinder and throttle valve needs to be cleaned.

2. If the engine has a little more water, but it does not affect the normal driving of the vehicle, but the engine is very loud. It may be that gasoline and engine oil are mixed with a small amount of water, and the owner can change the engine oil as soon as possible and clean the engine-related parts.

3. If there is a lot of water intake into the engine, the vehicle cannot be started and cannot be driven, and the cylinders, pistons and connecting rods of the engine may have all been deformed. If the above situation occurs, the engine is almost scrapped and cannot be repaired, and the owner needs to replace the engine with a new one, or simply scrap the vehicle.

1. If there is water ingress and stalling during the wading process of the vehicle, turn off the ignition switch immediately, do not try to start the engine again, move the vehicle to a safe place, and try to make the vehicle high in front and low in the rear, so that the water entering the exhaust pipe can flow out and avoid damage to the three-way catalytic converter and muffler.

2. After judgment, if the water enters the engine, the spark plug should be removed, and the motor should be used to transport the motor after artificially cutting off the fuel supply system and ignition system, so that the water entering the engine can be discharged smoothly. At the same time, check the oil status of each system of the vehicle, and replace it in time if there is foaming and turbidity. After the test is completed, compressed air should be used to clean the electrical connection parts inside the engine compartment to prevent corrosion caused by moisture accumulation in the electrical connection parts.

The key removal areas are: fuse boxes, sensor plugs, and water accumulation in the body. After the cleanup, the vehicle road test is carried out to confirm that the engine is free of abnormal noise during driving.

If there is significant driving noise, check the engine bearings and rotating parts.

3. If the water enters the compartment in the wading, the maintenance process is mainly to clean up the water in the car, and there are several sealant plugs located in the lower part of the vehicle chassis, and the water in the compartment can be released when the rubber plugs are opened. However, due to the strong water absorption of the interior decoration material floor glue, the floor glue should be removed, placed in a spacious space to facilitate the evaporation of water, after installation, it is also necessary to pay attention to turn on the air conditioner, adjust the vehicle circulation switch to the internal circulation, so that the water vapor in the compartment is discharged out of the car through the air conditioning system, which is a very fast dehumidification method in summer.

4. Chassis parts are easy to cause deterioration of lubricating oil in the process of wading, especially when it comes to steering, transmission and other systems. For example, the maintenance manual requires the Land Cruiser to grease the chassis components after wading through water. At the same time, you should listen carefully to the chassis for abnormal sounds during the road test, or disassemble and inspect the chassis.

I also got into the water on September 4 last year, but I didn't start the fire, so I called a friend from the 4S shop to come over, dismantle the air intake system, get the water out, and it will be fine in a while. Probably the process is like this, remove all the parts near the fan in front of me, take out all the cremation plugs, and then I don't know what kind of safety I pulled, let me use the high pressure inside to blow the water out. Put it on again, and it's all in one dozen.

The way to deal with water ingress into the engine is to contact the repair shop immediately to overhaul the engine and replace the parts according to the actual situation. Do not restart the car after the fire dies, every time there is heavy rainfall, many roads will have deep water, when driving, you should pay attention to the depth of water on the road. If the water is more than 20 centimeters deep, don't wade into the water.

Hello, according to your description, if the engine is flooded, the engine needs to be disassembled for cleaning and repair. Hope!

Water ingress into the engine is serious, and the engine needs to be dismantled for drainage.

The car engine got water and needed a major overhaul.

1. If the engine is just mixed with water vapor and enters the air filter, we only need to deal with it simply, and clean the water vapor from the air filter, throttle valve and cylinder.

2. If the engine has a lot of water, but it does not affect the normal driving, but the sound is relatively loud, it may be a small amount of water in the engine oil and gasoline, we need to change the oil and clean up the engine-related parts.

3. If there is a lot of water, the engine has been flooded, but the car has not been started, the engine has not caused damage, we need to drain the water, clean it up, and reinstall it and change the oil.

4. If the engine has a lot of water and cannot be driven after starting, the cylinder, connecting rod and piston of the engine have been deformed at this time, and the engine can be considered to have been scrapped, and we can only replace the new engine or scrap the car directly.

Water in the engine is not covered by the basic vehicle damage insurance, and you need to select the "Special Engine Damage Insurance" option at the time of insurance to get a claim. It's important to note that if you force the car to start the car again after the engine of your vehicle has been flooded and the engine is damaged, the insurance company will consider it intentional and will not pay compensation.

1. If your vehicle is flooded, whether it is parking and soaking in water or driving into water, don't save it alone, let alone start again, call a tow truck to minimize the loss.

2. Once something happens, don't worry about not being within the scope of the insurance claim, and call the insurance company to prepare the case (be sure to report the case within 24 o'clock).

This is not called engine water ingress, engine water inlet refers to the engine when the engine is working through the air filter to suck water into the engine, causing damage. It's just that the outside of the engine is wet, and it doesn't affect the use. If you don't feel at ease, leave the lid open for a while and let it dry.

There's no problem with this, a machine is a machine. Don't take it too seriously! Nothing. I used to clean my engine like this more than 30 years ago.

The car engine gets water, and it is dried and then used.

Once the vehicle stalls in the water, you must not try to ignite it again, because it is impossible to tell what is causing the ignition in heavy rain or wading in the water, so the most reliable thing to do is not to start the engine again. Generally, there are three situations of water ingress into the engine:

The first case: after the vehicle is soaked in water, the engine is not started until it is towed back to the repair shop; This situation is that the vehicle has only been watered once, and was towed to the repair shop afterwards, the engine has not been started halfway, basically will not cause irreversible damage to the engine, the main work is to clean up the water inside the engine, but the degree of cleanliness should be considered according to the situation, more cases, the air intake pipe and the air intake manifold are removed, and the water inside is blown dry by utilizing the compression space.

The second case: the vehicle is driving in water and the engine stalls due to water ingress; If your car is suffocated in water, the mechanic will most likely ask you to authorize them to disassemble the engine.

First of all, it is necessary to determine whether the connecting rod has been crushed and deformed during the abnormal flame-out. By the measurement of caliper, can compare the distance between two pistons formed in the same place and the upper edge of cylinder, if there is a difference in the numerical value between the two, the side with the larger value may be the connecting rod deformed, of course, it is also possible that both have problems, this needs to be by rotating the crankshaft to put two pistons in the top dead center position, see if the edge of the piston is flush with the upper edge of the rain cylinder to further confirm. After checking one by one, it is completely possible to determine which cylinder has the problem so that the relevant parts can be ordered.

But often for the maintenance engineer, in order to achieve better maintenance results, they advocate replacing all the connecting rods and pistons.

The third scenario: After a small amount of water ingress into the engine, the owner starts the engine and travels a certain distance without knowing it. How can you tell if your engine is damaged?

If the crankshaft cannot be rotated with a wrench, it can be preliminarily judged that the connecting rod is seriously damaged, and after disassembly, the engine block, connecting rod and piston should be replaced as a whole. The specific testing situation is the same as the second situation.

What should I do if the engine gets water?

If the engine is not damaged, remove the spark plug first, pat the water, and there will be no problem if it can run normally after installation.

First of all, it is necessary to roughly judge what kind of state the engine is in. There are basically three situations: first, the engine is flooded after the vehicle is soaked in water, and more importantly, the engine is not started until the vehicle is towed back to the repair shop; Second, the vehicle is driving in water, and it stalls due to water ingress into the engine; Third, after the engine is flooded (a small amount of water will not prevent the engine from starting), the owner starts the engine without knowing it and drives for a certain distance. These problems are discussed from the perspective of those vehicles that have not purchased the corresponding insurance, in fact, even if there is the corresponding insurance, when it comes to the assessment of damage, it is also based on the principle of saving money.

The second method:

If the vehicle turns off in the process of passing through the water, it must not be started again, there are three possibilities for starting again: first, it can still be opened, but the air filter water intakes, and the engine inhales air and brings part of the water into the air intake tract to form water vapor, and the water vapor is mixed with gasoline and fully combusted, which has little impact on the engine. Second, a small amount of water enters the engine, and after it is mixed with the engine oil in the cylinder, the oil quality becomes worse, and the oil containing water will increase the wear of the engine parts, and the engine noise and vibration may become greater in the future.

Third, start the engine again to make a sound after a few seconds and turn off again, and then start many times has not been able to start, this situation is the most serious, because the water can not be compressed, the engine is still working at high speed after the water enters the cylinder, and the water can not be compressed when doing work, which directly leads to the top bending of the valve and connecting rod, the piston is stuck, the cylinder is seriously worn, and the crankshaft is bent, it is recommended that the landlord replace the oil as soon as possible. Some models are designed with the air intakes on the fenders or on the hood, and the splash caused by driving in the water is also too high to compare. Remember to change the oil and blow the intake pipe clean.

First of all, it is necessary to judge the water ingress of the engine:Most people are aware of the dangers of water ingress into the engineThe easiest way to do this is to check if the color of the oil is abnormal, if the oil turns milky white, it means that there is water in the tank or engine.

As we all know, when the vehicle wades in water, the water enters the cylinder through the intake manifold, due to the incompressibility of the water, the piston movement stroke will become shorter, resulting in the bending or breaking of the engine connecting rod, and under extreme conditions, the broken connecting rod will fly out and break through the cylinder block. The reason why the car stalls in water is that the distributor loses its normal ignition function after the distributor cover is flooded, and the engine air filter element is soaked in water, resulting in increased air intake resistance and water ingress into the combustion chamber, and the spark plug cannot be ignited. If you restart the engine at this time, it is easy to burst the cylinder

If water enters the engine, water will also enter the oil, which will cause the oil to deteriorate and change its original performance. In this way, the engine oil can not play its role in lubrication, cooling, sealing, anti-corrosion, etc., and the engine will eventually be harmed.

Secondly, check whether the various pipes are flooded. Including the air filter and the casing under the air filter whether there are obvious traces of water ingress, and check whether there are obvious traces of water in the air intake pipe and air intake manifold. Finally, check whether there are traces of carbon deposits in the spark plug and the cylinder wall of the engine, remove the spark plug of each cylinder and check whether it is wet, when the engine is working normally, the position of the piston of each cylinder to the top dead center is the same, and the position of the top dead center point (compression clearance) of the cylinder wall is clear.

When the engine is flooded, the piston cannot reach the original top dead center position because the water is difficult to be compressed, the piston movement stroke becomes shorter, and the top dead center position will move down significantly.

In case of rainstorms, driving on the road can easily lead to water ingress into the engine, so what should I do if the engine gets water?

To find out the cause of water ingress, if it is not the problem of the engine, change the oil. If the cylinder head gasket is damaged, it is necessary to go to a professional repair shop to replace the cylinder head gasket.

When the vehicle passes through the waterlogged road, if the water is too deep, it may cause the engine to enter the water and shut down, if the vehicle turns off in the process of passing through the water, it must not be high or start again, even if a small amount of water enters the engine, it is mixed with the oil after entering the cylinder, so that the oil becomes worse, the oil containing water will increase the wear of the engine parts, and the engine noise and vibration may become louder in the future. It should be noted that if the engine is shut down due to water ingress, the engine is turned off again after starting the engine for a few seconds, and then starting many times has not started, this situation is the most serious, because the water can not be compressed, the engine is still working at high speed after the water enters the cylinder, and the water cannot be compressed when doing work, which directly causes the valve and connecting rod to bend, the piston is stuck, the middle cylinder is seriously worn, and the crankshaft is bent, at this time it may be necessary to tow the truck to the 4S shop or repair shop for inspection and maintenance. Therefore, when the engine of our vehicle enters the water, we must turn off the engine as soon as possible, call Qi Wu to rescue **, and wait for rescue.

It is strictly forbidden to start again and continue driving to avoid unnecessary losses.
