The onset of the rainy season, frequent rainstorms in the south, and even the rain-reducing north, have continued to rain this year. For many car owners, the biggest concern is to face stormy weather or multiple water sections. What if the engine accidentally enters water? How to repair it? Here, Xiaobian gives you some tips.
Once the vehicle water is turned off, you must not try to re-ignite, because in the heavy rain or wading state, can not determine what is causing the flameout, so the surest way is not to start the idea of ​​starting the engine. General engine water intake usually has the following three conditions:
In the first case: After the vehicle has been soaked in water, it has been dragged back to the repair shop and the engine has not been started; this situation is that the vehicle was only passed through the water once and was subsequently towed to the repair shop. It was not started halfway. The engine will basically not cause irreversible damage to the engine. The main task is to clean the internal water of the engine, but depending on the situation, consider the degree of cleanliness. In more cases, remove the intake pipe and the intake manifold. Use compressed space to dry the water inside.
In the second case, the vehicle is driving in the water, and the engine is turned off due to flooding; if your car is annihilated in the water, the maintenance engineer will most likely ask you to authorize them to dismantle the engine.
First, it is necessary to judge whether the connecting rod is deformed during this abnormal flameout. By measuring the caliper, it is possible to compare the distance between the two pistons at the same position to the upper edge of the cylinder. If there is a difference between the two values, the larger value may be the deformation of the connecting rod. Of course, it may be two. There is a problem with this. It is necessary to confirm that the edge of the piston is flush with the rain cylinder by rotating the crankshaft to bring the two pistons to the top dead center position. After one by one investigation, it is entirely possible to determine which cylinder has a problem in order to order related accessories. However, for maintenance engineers, they always advocate replacing all connecting rods and pistons in order to achieve better maintenance results.
The third situation: After a small amount of water enters the engine, the owner starts the engine without knowing it and runs for a certain distance. How to determine the damage of the engine? If you cannot turn the crankshaft with a wrench, you can initially determine that the connecting rod is severely damaged. After dismantling, the engine cylinder, connecting rod, and piston must be replaced as a whole. The specific detection situation is the same as the second case.
It is suggested that in the face of the situation of the engine's water intake, it is necessary to calmly handle it. I hope that everyone can minimize travel in bad weather and try to avoid this situation.
