What to do if the car gets into water and won t start.

Find professional personnel for maintenance, preferably a 4S shop.

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.

If it is ignited after suffocation in water, the engine will be scrapped directly, and the crankshaft connecting rod will be deformed.

Due to the incompressibility of the water, the piston travel will become shorter, resulting in bending or breaking of the engine connecting rod, and under extreme conditions, the broken connecting rod will fly out and break through the cylinder block. The reason why the car stalls in water is that the distributor loses its normal ignition function after the distributor cover is flooded, and the engine air filter element is soaked in water, resulting in increased air intake resistance and water ingress into the combustion chamber, and the spark plug cannot be ignited.

If you restart the engine at this time, it is easy to burst the cylinder, when the cylinder has been filled with water, the water is not compressible, causing the connecting rod to bend or even break.

Impact:

1. There is a situation where the water ingress will damage the connecting rod, that is, when the car is driving, it accidentally enters the river (the engine is running), the river water enters the cylinder, and the engine is turned off.

2. If the car is parked in the underground garage and flooded, as long as the water inlet treatment can be done, remove the water inside the engine, replace the lubricating oil, replace the three filters, clean the circuit, check the gear oil of the gearbox, replace the gear oil if necessary, and check the braking system.

Don't start again. Disassemble the flower plug to start draining, install the spark plug and try to start. The engine cannot be forced to start after water ingress, and the water cannot be compressed in the cylinder to prevent the connecting rod from deformation.

The intake duct needs to be cleaned. Air grid. Remove the spark plug, hit the motor, and drain the water in the tank!

If the vehicle is wading in water, and the water has already overflowed the door and entered the car, then your car is already soaked. This is when you need to determine one thing: whether the mechanical parts of the vehicle are still in working order.

If the car can be driven without any faults, then the water in the car must be dealt with first. This is done by removing the floor mats from the interior of the car until the steel plate under the car is exposed. There will be drainage holes on the steel plate under the car, and after draining all the accumulated water, wipe the bottom plate.

Then it is necessary to strengthen the ventilation of the interior of the car for a period of time, and you can also place a bag of lime powder to absorb moisture.

1. Remove the negative wire of the battery as soon as possible to avoid short circuits caused by water ingress in various electrical appliances on the car.

2. Check the engine immediately, first check whether there is water in the engine cylinder, which will cause the connecting rod to be bent and damage the engine.

3. Check whether there is water in the oil, which will cause the oil to deteriorate, lose its lubrication effect, and make the engine wear excessively.

4. Check whether the gearbox is flooded, and the gearbox water will cause the gear oil in the gearbox to deteriorate, resulting in gear wear.

5. Check the brake oil, the water in the brake oil will deteriorate the brake oil, resulting in brake failure.

6. If water enters the exhaust pipe, the stagnant water should be removed as soon as possible to avoid impurities in the water blocking the three-way catalytic converter or damaging the oxygen sensor.

7. Check whether the battery is full of water, and replace the electrolyte if necessary.

8. The automatic transmission car should check whether the automatic transmission and the transmission control computer are flooded.

9. Dry the soaked items (seat covers, floor mats, etc.) in the car as soon as possible to avoid mold.

Hello dear! Friend, first of all, I want to tell you, if the vehicle turns off in the process of passing through the water, it must not be started again, there are three possibilities to start again: first, it can also be opened, but the air filter water intakes, and the engine inhales air and brings in part of the water to the intake tract to form water vapor, and the water vapor is mixed with gasoline and fully combusted, which has little impact on the engine.

Second, a small amount of water enters the engine, and after it is mixed with the engine oil in the cylinder, the oil quality becomes worse, and the oil containing water will increase the wear of the engine parts, and the engine noise and vibration may become greater in the future. Third, start the engine again to make a sound after a few seconds and turn off again, and then start many times has not been able to start, 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 cylinder is seriously worn, and the crankshaft is bent, it is recommended that the landlord replace the oil as soon as possible. Some models are designed with the air intakes on the fenders or on the hood, and the splash caused by driving in the water is also too high to compare.

Remember to change the oil and blow the intake pipe clean!

Hello, after the car is flooded, you must not continue to ignite, which will cause water in the engine compartment to be overhauled. If my answer is helpful to you, please set it to.

1. Take the wire: This is a necessary item for the car to take the electricity, do not take two wires to make do, because the instantaneous current of the vehicle at the start can reach 200-600A, and the diesel car even reaches 1000A, if it is calculated, 10 square copper wires can ensure the smooth and safe start, so the car battery connection line must buy the right brand, the quality is the best, do not try to be cheap. This is one of the must-have items in the car, once the battery is out of power, you can take it out and use it, and you can also help others when you don't use it.

2. Emergency power supply: This is a new type of power bank like a thing, there are two kinds of lead-acid and polymer lithium battery, which can help the vehicle with a loss of power to start, and can also have lighting, charging mobile phones and multi-functional supplies used with an inflatable pump to inflate the car. And it is generally portable, very lightweight, if you have it, you don't have to ask others for help.

Be sure to charge it in time after use and keep it full of power to deal with emergencies.

3. Positive, first connect the positive: first turn off all the electrical equipment on the car, make the key in the OFF position, open the cabin cover to find the battery, there are positive and negative poles written on the battery, generally the red "+" sign is the positive pole, and there are generally two wires, at this time, take out the red one, open the battery cover, pinch the clamp on the head to clamp firmly the positive pole of the battery of the electric car, and the clamp at the other end to clamp the positive pole of the battery of the rescue vehicle. Be sure to connect the positive electrode first, then the negative electrode, do not reverse the order, and do not use the battery clamp to touch anywhere except the battery pile head.

4. Negative connection, negative connection: After the red positive electrode is connected, take out another wire, first clamp the negative pole of the tram battery, the negative electrode is generally black "—" number, and then pinch the other end of the clip, from beginning to end the clip do not touch other places, to clamp the negative pole of the rescue vehicle battery, when the connection will pop out of the electric spark, please don't be afraid, this also shows that you are right. The reason why the negative electrode is not connected first is because the whole vehicle is basically a negative electrode (that is, commonly known as "tie iron"), if the negative electrode is connected first, when connecting the positive electrode, the clip will cause a short circuit and burn the parts on the car when it touches any conductive place in the body.

5. After starting the vehicle, first remove the negative, and then dismantle the positive: after the battery is connected, the rescue vehicle will first ignite and charge the battery, and then the no tram enters the vehicle to open the key, at this time the instrument light will be lit smoothly, and then try to ignite (not more than 5 seconds), if it fails to start smoothly, step on the accelerator of the rescue vehicle, and the speed is kept at about 2500 rpm, and then the tram is ignited again, if the starter is no problem, the car has oil in the case of general can be started smoothly, after the non-electric vehicle starts, Remove the negative clamp first, then remove the positive clamp, for the same reason as why the negative pole is followed by the fourth one.

The positive and negative poles of the battery must not be reversed, and the order of assembly and disassembly should be strictly in accordance with the order of first connecting the positive and then the negative, and the first dismantling and then the positive.

If the engine does not catch fire after water is in, if it is just that the high-voltage line or ignition system (gasoline engine) is wet with water and does not catch fire, it is enough to dry the water. If the oil pan oil is filled with water, you must not force the engine to start, just put the oil out and clean the oil pan and add the oil. If there is water in the intake pipe or exhaust pipe into the combustion suffocation, do not force the engine to start, because the water is incompressible, such as forced start will bend the connecting rod or piston pin, crush the piston or crankshaft or cylinder block is fractured.

The cylinder head must be opened and the water must be cleaned before starting the engine.

If the secondary starter repair is more troublesome, go to the repair shop to dismantle the engine to clean and change the oil.

Pour out the stagnant water inside, and never start a fire, otherwise it is easy to break the valve. The correct way is to remove the spark plug, disconnect the fuel injector plug, hit the starter, wait for the water in the cylinder to drain out, change the engine oil, and then install the spark plug and fuel injector plug to start the engine.

If the water does get into the engine, you should have to go to the repair shop to see what the specific problem is, and also to see what the insurance will pay.

What should I do if the car doesn't catch fire and gets into the water? After the water is ingress, it is easy to cause the piston connecting rod to bend up, you need to check whether the piston connecting rod is bent up, if it is bent up, you need to overhaul the engine.

The car has stalled due to water ingress and cannot be started a second time, otherwise the engine will cause irreversible damage or even damage. If you don't start it twice, you can fix it quickly when you go to the garage.

If the car does not catch fire, if the engine gets water, do not start it again, otherwise it will cause damage to the engine, and the insurance company will not compensate. You should report the insurance immediately, and the insurance company will find a tow truck to tow it away.

According to your description. In this case, it is recommended to go to a repair shop for an inspection to determine the specific cause of the failure. Then carry out targeted maintenance. Hope, thank you.

As long as the engine is not started after the water is in, it is fine, but if it is started, the engine will basically be scrapped, and it will need to be replaced or overhauled.

1. The spark plug should be checked first. Because the spark plug is the key to the ignition system of the car, and the ignition system is the key point of the engine work, the performance of the spark plug is related to the working performance and efficiency of the whole vehicle.

2. The battery loses power - its performance is characterized by the starter starting to rotate but the speed is not enough, that is, it is weak, and then the starter only clicks and does not turn. Low temperature in winter and forgetting to turn off individual electrical equipment will cause the vehicle to be unable to start, especially in winter for long-term short-distance low-speed use, the battery voltage will be lower than the rated value, starting and unable to operate normally. If it happens, please call the service station for rescue**, or find the right car, or temporarily on fire, and then you must go to the service station to replenish the battery.

3. The flow of gasoline is blocked - the performance is characterized by no oil pressure in the engine oil supply pipe. This situation usually occurs in the morning when the temperature is very low, and is caused by long-term dirt in the fuel line. When the temperature is very low, the water mixes with debris and the fuel line is blocked, and as a result, it cannot be started.

Emergency method: Put the car in a warm environment, and the car can start after a while; Or use the method of cleaning the oil circuit to solve it completely.

However, summer is also the rainy season, and driving is inevitable, so many cars will encounter such problems: the car can't start after being flooded? So what should I do if I tremble?

Not everyone will encounter such a problem, but we still need to know some workarounds. Below, we will detail three situations and solutions for cars that won't start after water ingress. First of all, with the continuous improvement of people's living standards, cars have become an indispensable part of people's lives, so it is also common to drive in summer.

The inability to start a vehicle after being flooded is a common condition for car travel. In this case, this article will discuss from the perspective of those vehicles that have not purchased the corresponding insurance. Secondly, there are three main situations in which the car cannot be started after entering the water.

One is that the vehicle is immersed in water, which causes the engine to enter the water, and more importantly, the engine has not started until the vehicle is towed back to the repair shop; Second, the vehicle is driving in water, and the engine stalls due to water ingress; Third, after the engine enters the water (a small amount of water will not hinder the engine from starting), the owner starts the engine without knowing it and travels a certain distance. The workaround is different for different situations. If the vehicle has only been watered once (not turned off in water, but soaked in water) and dragged to the repair shop afterwards (the engine has not yet started), it will not cause irreversible damage to the engine.

The main job is to clean the stagnant water inside the engine, but the degree of cleaning should be considered according to the situation. More commonly, the intake pipe and intake manifold should be removed and the water inside should be dried with compressed air. Stagnant water in the cylinder can be removed from the spark plug and then dried.

However, it is important to pay attention to safety during the process of removing stagnant water. After cleaning up the engine water, it is also necessary to check whether the oil has entered the lubrication system. If the oil is found to be cloudy, the oil needs to be changed.

In addition, in the case of connecting rod and piston problems, it is necessary to check them one by one and replace them according to the measured results. Finally, the corresponding oil needs to be changed after assembling the engine. In short, the problem that the car cannot be started after water ingress needs to be analyzed and solved according to the specific situation.
