How to drive correctly after the vehicle wades in the water and what is the treatment method after i

1. Be cautious about wading in the water.

If the vehicle is flooded and the water level is high, the owner should not start the engine forcibly, first of all, turn off the power supply, contact the insurance company or the repair shop, and they will go to the scene to deal with it; If the water level is not high, the owner can drive the vehicle to the repair shop or the insurance company's damage assessment point for inspection, and if any parts are damaged, he can claim compensation from the insurance company. It is worth reminding that never when passing through stagnant water"Skimmer"so that the pipes do not suck water back into the engine.

2. Do not restart after turning off the ignition.

The stagnant water entering the cylinder block does not have the effect of lubrication, and restarting the engine will cause serious wear and tear of the engine piston and cylinder block, and even lead to the scrapping of the engine in serious cases.

Operate in different situations.

1. When the car is driving, it encounters a waterlogged road.

First, you should slow down or stop and observe. As long as the water level reaches two-thirds of the bumper or tire, there is a certain danger of wading in the water. High speed increases the actual depth of the car's water crossing, causing rain to enter the cab from the cabin or from the chassis.

Avoid driving against the waves with large vehicles. If the water level is high through observation, you should try to detour as much as possible and do not force your way through.

Second, in addition to maintaining a low speed when the car wades in the water.

Also try not to stop, not to shift, not to throttle, and not to accelerate. It should pass at a constant speed in low gear and at high throttle, not over large waves or splashes.

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.

Wading Tips:

One look: When the city encounters heavy rain and the road is waterlogged, most of us often do not know the depth of the water surface due to the dirty and turbid water quality, especially in some potholes and uneven sections. At this point, it is necessary to pull over and observe the passing of other vehicles.

Second Exploration: If there are no other vehicles to provide reference, then you will have to explore the depth of the water on your own. When exploring the water, you can estimate the depth of the water with the help of umbrellas, branches on the side of the road, or by reference to the greenery of the roadside. If you are not absolutely sure, do not go into the water recklessly.

Three passes: The first point of driving is to be slow, do not hit the accelerator with a big foot, so as not to cause the consequences of water filling into the engine due to the water level pushing up. In the process of traveling, it is necessary to maintain a low gear and high speed, and slowly pass through the water at a uniform speed.

The purpose of this is to get the slowest speed and maximum torque by using the vehicle's lowest gear. Slow driving, of course, is to prevent water from entering the intake pipe; If an obstacle is encountered, the maximum torque output in the low gear allows the vehicle to cross the obstacle.

processing methods; 1. Check whether the brakes are normal.

After successful wading, do not rush to speed up, continue to maintain a low speed for a period of time, and step on the brakes a few times over the section where there is no water to avoid brake failure and rear-end accidents. This practice can not only check whether the brakes are normal, but also make the brake disc and brake pads fully rub, so that the residual moisture can volatilize as soon as possible, so that the vehicle can recover the braking force faster.

2. Go to the 4S shop to check the air filter and other important parts.

In addition to checking the brake pads by themselves, it is recommended that the driver send the vehicle to a 4S shop for inspection after the vehicle wades, especially the key parts such as the air filter and the wiring harness interface in the engine compartment.

3. Give the chassis a "bath" when washing the car

On rainy days, the water on the road is dirty, and there will be various debris such as fallen leaves. When the vehicle is wading, these debris can easily adhere to the chassis gaps and other places, which will rust the chassis over time. Therefore, it is necessary to "take a bath" of the chassis when washing the car and do a thorough cleaning.

What to do with a car after wading in water?

In the face of various factors such as heavy rain or high winds, low and bright ridges on urban roads, it is difficult for us to ** what will happen, but how should we calmly deal with these problems? Bian Xiao has provided you with relevant information. 1.

If the vehicle wades through water while driving, and the ignition stalls in the water, you need to stay calm, turn off the ignition immediately, and do not try to start the engine again, because this will cause great damage to the engine, and the insurance company will not handle the claim; Then remove the negative wire of the battery as soon as possible to avoid water ingress causing a short circuit in various electrical appliances on the car, and then move the vehicle to a safe place, try to make the front of the car high and the back low, so that the water entering the exhaust pipe can flow out and avoid damage to the three-way catalytic converter and muffler.

2.After the car comes out of the water, check the engine: first check if there is water in the engine cylinder, which will cause the connecting rod to bend, damaging the engine.

After judgment, if it is determined that water has entered the engine, the spark plug should be removed first, the oil supply system and ignition system should be artificially cut off, and then the motor should be used to transport the motor to make the water entering the engine be discharged smoothly.

3.At the same time, it is necessary to check the oil condition of the vehicle's various systems to avoid foaming, turbidity and deterioration after the oil enters the water, loss of lubrication, and excessive wear and tear of the engine caused by sand particles in the water. At this time, it should be cleaned and replaced in time.

After the test, it is necessary to clean the electrical connection parts in the engine compartment to prevent corrosion and sand slag due to the build-up of moisture in the electrical connection parts. The key components that need to be disassembled are: fuse box, sensor plug, and water accumulation on the body.

After the above-mentioned parts are cleaned, the vehicle can be tested on the road, try to maintain medium and low speed, and listen carefully to whether there is abnormal noise during the driving of the engine. If there is significant driving noise, the engine bearings and rotating parts should be inspected again to avoid damage caused by excessive wear.

4.If water enters the carriage when wading, the maintenance process is mainly to clean up the water in the compartment. There are several sealing strips in the lower part of the chassis of the vehicle, which can be opened to drain the water in the cabin.

However, since the adhesive used as an interior material is highly absorbent, the adhesive should be removed and placed in a spacious, empty room to facilitate moisture evaporation. After installation, pay attention to turn on the empty switch and adjust the circulation switch in the car to the internal circulation, so that the water vapor in the compartment can be discharged out of the car through the empty switch system, which can effectively dehumidify and prevent mold and deterioration of vehicle supplies.

5.Chassis components are prone to deterioration of lubricating oil during wading, especially in systems such as hail and gearbox. At the same time, during the road test, listen carefully to whether the chassis has abnormal noise, or check the disassembly and assembly of the chassis.

6.Check whether the gearbox is also flooded, because water ingress will cause the gearbox gear oil to deteriorate, the lubrication effect will be ineffective, and long-term use will cause gear wear. Automatic transmission models also need to check whether the automatic transmission and transmission control computer are inundated.

7.Brake fluid and four-wheel brake are items that must be inspected, and they are important items related to driving safety. The key point to check here is the brake fluid, if water enters the brake will deteriorate, leading to brake failure and even traffic accidents.
