1, cylinder liner is damaged
There is oil in the water tank, probably because the cylinder liner is cracked. Under high pressure, the engine oil will pass through this gap and directly penetrate into the automobile water tank.
2. The radiator is damaged
Secondly, if the oil radiator or gearbox radiator is damaged, it will also lead to oil mixing in the water tank, which needs everyone to check.
3. Cylinder gasket is damaged
If there is oil in the water tank and the high temperature light in the water tank is still on, it is probably because the cylinder gasket is damaged. Because the fuel in the cylinder is under high pressure for a long time, so that the cylinder liner is damaged, then the oil circuit and waterway at this time are equivalent to the state of intercommunication.
Generally speaking, there are many factors that lead to the oil in the water tank, which need to be checked one by one. If damage is found, just replace it with a new one. Of course, we have to clean the water tank thoroughly afterwards. After all, it is mixed with some engine oil, which will definitely affect the normal efficiency of the coolant.
