What to do if your car gets flooded? What to do if the car engine gets water

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.

As we all know, in some places with more precipitation in the south of our country, we often see the news of flooded cars. Even if there is no immersion, what if there is inevitably rain splashing into the engine when passing through some wading sections? Bian Xiao will give you a detailed answer today.

What should I do if the car engine is flooded?

1.Do not force the engine to start again, and do not force the engine to start again, this can easily cause the engine to be cylinder**. If the purchase involves marine insurance, the insurance will not pay out.

2.The vehicle needs to be towed to the repair shop for imitation rubber repair, and in severe cases, the engine may need to be replaced.

What does the engine look like when it gets water.

1.Look at the height of the flood. If the height of the water exceeds two-thirds of the vehicle, there is a high chance of water ingress.

2.Check the color of the oil. If the oil has a milky mixture, it may be caused by water ingress into the engine.

3.Inspect the air cleaner and air intake duct for visible signs of water leakage.

4.If white smoke comes out of the exhaust pipe while driving, it may be that water is entering the engine.

Hazards of water ingress into the engine.

Due to the incompressibility of the water, the travel of the piston is shortened, causing the engine connecting rod to bend or break, or even the cylinder**. At the same time, some electrical appliances and engine air filter elements can also be flooded, increasing the intake resistance, making the vehicle unable to ignite.

The above is the answer to what to do if the car engine is flooded and what is the performance of the engine when water is ingress. It should be noted that when passing through the water part, millions of subsidies for the purchase of cars.

1. Remove the spark plug, artificially cut off the fuel supply system and ignition system, and use the motor to transport the water to drain the water. Foaming, turbidity and other phenomena should be replaced.

2. After the test is completed, use the compressed air to clear the electrical appliances in the engine compartment and the sliding parts, and after the cleaning is completed, the vehicle road test is carried out.

3. If there is obvious driving noise, check the engine bearings and rotating parts of Hail. After removing the spark plug, the engine is started and does not rotate, indicating that the engine is ejected to death and sent to the maintenance station for processing.

After the car is soaked in water, do not try to start or turn the engine, otherwise it will cause serious deformation of the engine connecting rod. And the consequence of forcibly starting the engine is that it is often denied by the insurance company. Therefore, it should be towed to the maintenance plant as soon as possible for dismantling and cleaning, and the disposal of the engine requires the disassembly of all the spark plugs of the vehicle, and finally the cylinder pressure test is done, usually the cylinder pressure of the gasoline engine is in the range of 900kpa to 1100kpa.
