How to repair the vehicle accidentally flooded?

In summer, the amount of precipitation increases, and in some low-lying areas, vehicles are prone to flooding, which has an extremely adverse impact on the safety of vehicles and cargo and the performance of the vehicle itself. When the stagnant water recedes, what measures should car owners take?

1. The accumulated water has not passed the axle

The axle is the part with the smallest height from the ground except the tire. Once the accumulated water has soaked the axle, the owner should pay attention to the following points:

Check and replace the gear oil inside the drive axle, because the casing of the drive axle is generally designed with air holes, if the sealing is poor, the accumulated water will enter the inside of the drive axle through the gaps and air holes, causing the oil to emulsify. Lead to lubrication failure and damage to the basin teeth;

Check whether the braking performance of the vehicle is affected, especially the axle of the drum trailer, it is easy to retain foreign matter such as water or sediment, which will cause the braking effect to decrease or the abnormal wear of the braking system. Therefore, if conditions permit, it is best to disassemble the braking system. Drums, clean the sediment deposited inside, wash the brake pads with clean water, etc.;

Check whether there are sundries in the brake air chamber. The exhaust hole of the double-chamber air chamber is under the water surface, so it is easy for water to enter, and sundries are easy to enter, resulting in blockage of the air circuit. In severe cases, it is easy to cause the brake failure of the trailer. Check;

Check the wheel end parts, disassemble the wheel end, check whether trailer axle there is water in the interior, whether the sealing rubber ring is leaking, whether the oil is polluted or emulsified, etc. If there is a problem, replace the new parts in time and add new lubrication Oil.

2. Water accumulated over the transmission shaft

If a grease nipple is designed on the transmission shaft, remember to check and replace the deteriorated grease after the accumulated water recedes to ensure that the performance of the transmission shaft will not be affected. If there are grease nipples on other structures of the car body and are submerged by stagnant water, the grease should also be replaced and filled.

3. Water accumulated over the gearbox

Water ingress will also occur inside the gearbox. Once water enters, the valve body and electronic control system will fail, and the internal oil will deteriorate and lose its lubricating effect. Therefore, after the height of the accumulated water exceeds the gearbox, the owner must remember not to continue driving, otherwise it will easily cause more serious damage to the gearbox. You should contact the towing company as soon as possible to move the vehicle to the repair shop for inspection and maintenance.

In addition, when the accumulated water passes through the gearbox, the suspension is basically unavoidable. If the owner uses air suspension, remember to clean the airbags and shock absorbers, and ask the repair shop to repair the electronic control system and air suspension. The height is detected and adjusted to avoid uneven inflation and inconsistent height.

4. The accumulated water has covered the engine

The flooding of the engine is a relatively serious and difficult problem to deal with. The owner needs to replace the engine oil and filter; check the fan, belt tensioner and other positions with exposed bearings, and replace them if necessary; check the entire vehicle Whether there is rust in the electric control wiring harness, replace the corresponding accessories in time; the air circuit connector, quick release valve, handshake valve, and water vapor in the air circuit should also be cleaned together; The water vapor in the road is blown dry with compressed air.

The owner of the car should pay attention to that once the height of the accumulated water has submerged the engine, even if the accumulated water recedes, the engine must not be started to avoid secondary damage and affect the insurance company’s compensation. If you need to move the vehicle, you should contact the towing company.

In addition, the car owner should check the fuel tank and urea trailer axle tank on time, especially after a long period of heavy rain, even if the vehicle is not soaked in water, check the oil and urea tank, because any problem with these two containers will cause the vehicle to stall .

It is recommended that car owners who often go in and out of rainy areas purchase corresponding insurance, "raising soldiers for a thousand days and using them for a while", if the vehicle is flooded, you need to contact the insurance company in time:

1. Do not start the vehicle after it is flooded;

2. Take pictures on the spot and take pictures of the license plate number at the same time;

3. Call the insurance company to report the case (be sure to report the case within 24 hours);

4. Call the rescue tow truck, tell the insurance company which repair shop the car is in, and let the surveyor investigate;

5. Before maintenance, report and verify the loss to the insurance trailer axle company as required.
