The engine was seriously damaged by wading, does the 4S shop have any technical proof that it was ca

Hello. Hard.

The engine is wading, if it is driving, before the engine automatically turns off, there has been damage (such as bent connecting rods) and can only be repaired; If you wade in the process of parking, do not start, contact the trailer, drag out the internal drainage of the rear cylinder, wiring harness and various parts of the engine room before starting, if there is no drainage treatment, there will still be a risk of damage to the inside of the engine, and this damage can be completely avoided.

Hello. 1. After the car wades in the water, the motor will be started again only when the ignition is turned off, and the starting motor does not respond at this time, which belongs to the second start. The second start is that the car is drowned underwater, and then the key is screwed again underwater to ignite the ignition, if you are on the water insurance, the non-ignition and the secondary ignition correspond to the claim can be claimed and can not be claimed.

2 Typically, there is a 50% chance that engine damage will occur if the vehicle stalls in water. But if it starts again after the ignition is turned off, then the engine will definitely be "scrapped".

3 Therefore, whether the owner is driving, or stopped in the community, basement, or street, the car must not start again after turning off the engine after wading. Some insurance companies will also take the second start after the water ingress is turned off as an exemption clause for wading insurance, that is, if the car owner tries to start a second time after the car is flooded, the resulting engine damage will not be compensated even if it is on the wading insurance.

Not necessarily. If there is no water in the engine, there will be no engine damage. If there is water in the engine, it will cause damage to the engine. Do not start the engine again when the car turns off after wading, because the stagnant water is sent through the intake pipe to enter the engine.

Proper operation of the car after wading.

Do not start the car when the engine is turned off after wading. If water accidentally enters the engine while driving, it should be turned off immediately, because once the stagnant water enters the engine, it will cause the engine to fail instantaneously, causing the car to stall. If the car is turned off and then restarted, the cylinders with water will be impacted by the compressed water, causing severe wear and tear on the cylinder block, and finally even causing the engine to be scrapped directly.

What to do if the car gets into the water.

Do not start the car when the vehicle is flooded. Instead, take a picture on the spot and list the license plate number. This can be used as evidence for a claim.

After the shooting, call the insurance company, then tell the insurance company the location of the car, then turn off the power of the vehicle, and then push it to a safe place, and then let the insurance company investigate the damage, and then carry out repairs.

After the car is repaired after flooding, there will be no problem with selling?

Even if the vehicle is well repaired after entering the water, it is easy to have problems. If the vehicle is heavily waterlogged, it must be thoroughly disassembled and inspected to replace the electrical parts that have been soaked by WHO. After the maintenance is completed, the various functions of the vehicle are subjected to static and dynamic testing to ensure that the vehicle is repaired to meet the requirements, and finally a comprehensive interior cleaning is carried out.

1. Although the start is normal, but your engine cylinder has been flooded, the water is poured into the engine through the exhaust pipe, because the engine has a corresponding protection system, it causes your flameout, but because you have not undergone any treatment to start the second time, the exhaust pipe part of the water is directly sucked into the engine cylinder;

2. Due to the second start, even if the engine is processed later, the service life is greatly reduced, and the possibility of failure is also very high, and it is certain that it cannot be restored to your original engine. In the end, there are only 2 results, replace the engine or sell the car;

3. Start the engine again and make a sound for a few seconds after turning off again, and then start many times has been Qi Hu Shen can not move, 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 middle cylinder is seriously worn, and the crankshaft of the shed ruler is bent, it is recommended to replace the machine pants and oil loss as soon as possible.

It's better not to do that.

There are several scenarios for a fire to go out in the water:

First, the water floating Gongdi clamped the locust electric Wei nail company did not enter the engine, but only wet the wire, and the guide roll accompanied the leakage, so that the spark plug could not get enough ignition energy to stop the engine;

2. Water enters the combustion chamber of the engine along the intake pipe, resulting in flameout;

3. The water only enters the oil pan, which increases the downward resistance of the piston, and leads to the ignition of the big digging stupidity;

If it's just the first case, it's still lucky, wipe the water dry, start again, there is no problem at all, if you can't be sure what kind of situation it is, the most scattered which is better not to start again, it is possible to break the connecting rod, break the cylinder block, or the bearing ablation, resulting in the crankshaft scrapping and so on.
