After the engine floods, you should first take initial corrective measures according to the specific situation to avoid secondary damage to the vehicle. Find out the key to the problem and determine the extent of damage to the car.
After understanding the specific situation, if you find that water has entered the engine, you should remove the spark plug and artificially prevent the fuel supply system from starting and d ignition, so that the water in the engine can be drained successfully.
Once the inspection is complete, use compressed air to treat the electrical connections inside the motor to prevent water from corroding them.
The parts to pay attention to are: the fuse box, the sensor socket and the body water accumulation area.
After cleaning, test drive the vehicle to ensure normal engine operationduring use.
Repair Guide for Flooded Vehicles
1. Water passage is less than one third of the tire:
Water passage is divided into different degrees and levels. If your car only wades slightly in the water, less than a third of the tire size, then you don't have to worry too much. You can eliminate hidden dangers as long as you do a little inspection yourself.
Check if there is any trash attached to the chassis. Rain in Beijing is acidic and will corrode tire paint and rubber. To protect the paint and tires of the car, the car should be cleaned in time. .
2. Water flooding up to one third of the tire:
If the water reaches more than one third of the tire, clean the sound insulation cotton in time.
Having the tire flooded more than a third of the way is the limit for repairing it after wading through water. Because if this limit is exceeded, the waterwill leak upward through the water-permeable holes in the vehicle floor, thereby wetting the sound insulation cotton inside the chassis.
1. Abnormal noise from the body
Abnormal noise from the body is the most common. It is generally caused by insufficient body rigidity over a long period of time. -long term intense driving or a lot of walking on bumpy roads. This will cause the steel frame of the car body to be slightly deformed. The most direct impact is abnormal impact or friction between the door and the car, or abnormal friction during some welding or. screw parts, which may also cause abnormal noise; some cars have more wind noise, to some extent this is related to the shape of the car.
Solution:
These abnormal noises are not terrible and will not have a big impact on performanceoverall vehicle ances, but they are annoying to deal with and difficult to cure. can only be caused by abnormal conditions. Add rubber pads or sponges to areas of friction or impact.
2. Abnormal noises in the car
Abnormal noises in the car are the most common, and there are many places where abnormal noises occur, such as improperly installed decorative panels and the glove box. of the driver Loosening, impact of seat belt buckle, etc.
Solution:
Reset it automatically or fill it with soft objects.
3. Abnormal brake noise
If there is a “squealing” sound when applying the brakes, it is most likely caused by excessive wear of the brake pads, resulting in excessive gaps. Of course, if the brake disc material is misused or deformed, the brake hardness, porosity, friction characteristics and characteristicsUnsatisfactory compression characteristics of the sheet may cause abnormal noise.
Generally speaking, the lifespan of front brake pads is 30,000 kilometers and that of rear brake pads is 120,000 kilometers.
Solution:
Abnormal brake noise can usually be resolved by replacing the brake pads. If the brake disc is damaged, it must also be replaced. When replacing, be careful. Model and other issues, otherwise the mismatch will still persist. There will be an abnormal noise.
4. Abnormal suspension noise
The suspension system continues to operate while driving and the rubber bushings between the shock absorbers and each connecting rod inevitably wear out as the bushing ages or. falls, there will be abnormal metal impact sounds. If the shock absorber is broken, there will be a "dong dong" or "click" sound on bumpy roads.
Solution:
Generally, abnormal suspension noise cannot be solved by yourself. You need to go to a repair shop or 4S workshop to have a specialized master replace the parts. If this occurs, it must be resolved as quickly as possible. It is best to strengthen inspections during daily maintenance to avoid the occurrence of abnormal noises.
5. Abnormal noise from tires
Abnormal noise caused by tires is generally tire noise. The noise generated will also depend on the car's driving speed, tire type, tire pressure and road surface. conditions, etc. Factors produce various noises of different strengths and weaknesses. When there is a faint “pop” noise, it is mainly due to tire tread deformation, bagging, heavy wear, or insufficient air pressure. If there is a “clicking” sound, the tread may be mixed with small stones or nails. .
If the wheels make a collision and metallic friction noise while driving, it is likely that the shock absorbers and bearings are damaged. Car owners should be careful when encountering these problems, even just driving nails can be dangerous.
Solution:
If you find that the tread is mixed with small stones, you can clean it yourself. Other issues should be brought to the attention of the car owner and handled by professionals.
6. Abnormal noise from steering wheel
Abnormal noise will be detected when the steering wheel is turned left and right. When an abnormal noise occurs halfway, it may be. essentially considered an abnormal noise coming from the steering gear. If it is difficult to determine the source of theabnormal noise after turning the steering wheel, the most common response obtained when going to a 4S shop for testing is friction of the rubber sleeve of the steering wheel. the ball joint of the steering rod.
In addition, abnormal noises may also be caused by oil leakage from the steering gear cover, insufficient tightening of the power assist belt, or aging.
Solution:
The tie rod ball joint is getting old and the steering gear has problems and needs to be replaced in time.
7. Abnormal noises in the engine compartment
The situation of abnormal noises in the engine compartment is complicated and requires careful investigation.
If the belt squeaks or whistles, it is usually due to belt slippage. If it is an air leak noise, it may be caused by a blockage or breakage in the exhaust system or vacuum tubes; if there is friction andabnormal noise from external metal parts when the engine is running, this can usually be caused by damage to the generator, water pump, etc.
Solution:
Find a professional to repair it as soon as possible
8. Abnormal gearbox noise
If there is a “whistle” inside the gearbox while the car is moving, or a whistling sound when shifting gears, it may be whether the bearings or gears of the gearbox are worn, or the bearings are worn due to stains.
If the gearbox makes an abnormal noise when accelerating and changing gears, the gearbox oil may contain metal powder, indicating excessive gear wear. the brake belt of the gearbox, clutch and other components.
Solution:
The gearbox is precision equipment, so regardless of abnormal noise itIf occurs, it must be repaired in time.
