1. The water tank is broken, and the autotransformer oil is cooled by the water tank. If the cooling pipe inside is broken, it will flow into the water tank.
2. It may be that the oil seat is connected with the water channel, because the oil filter seat of this car has a water channel to cool down. If it is corroded, the oil circuit will run into the water channel with high pressure, and it is unlikely to wash the cylinder gasket.
Extended data:
Reasons for excessive consumption of antifreeze:
1, the radiator is damaged, and the sealing of the upper and lower water chambers is not good, resulting in antifreeze leakage.
2. The joint surface of overflow box, water pump and cooling system pipe fittings is loose and poorly sealed, resulting in antifreeze leakage;
3. The cylinder gasket is damaged, the flatness of the joint surface between the cylinder head and the cylinder block is out of tolerance, and the fastening bolt of the cylinder head is warped and loosened, which leads to the high-temperature and high-pressure gas in the cylinder entering the cooling system, resulting in excessive consumption of coolant.
Many people think that antifreeze is only used in winter, but to correct this misunderstanding, antifreeze is not only used in winter, but also used all year round. When the water leakage is lower than the standard value, the water level warning light will flash, and some with display screens will prompt the cooling system failure.
There are many reasons for engine overheating:
1. The most common reason is that scale, scale, gel and other dirt accumulate in the cooling system, blocking the waterway and reducing the cooling effect of the cooling system.
2. In the past, the common way to eliminate this kind of fault was to remove the water tank for replacement, but it turns out that the situation of many cars has not been improved, but the engine fault light is not on. It is not enough to add a water tank to the main water tank, because the water difference is too big. The water can't pass at once. It is best to open the main water tank before starting when the car is cold. Too much difference, the air will be exhausted.
