1) Check whether the water tank leaks, open the water tank and see if the water level is lower than MIN. If the water level is very low, it is likely to leak. Add water, open the exhaust screw near the engine to exhaust, and check the water leakage point.
2) Water leakage is generally caused by a cold car. After the hot car is cooled, check it, and pay attention to whether there is water leakage in the hot water pipe joint leading to the cab. You'll know when you get up in the morning with a lot of water leakage.
3) The cylinder gasket needs to be replaced. Replace the water temperature sensor. Both sides have been heated for a long time, and the fan blades of the water pump are broken, dropped or blocked. Once I saw with my own eyes that there were many rubber strips twisted in the water pump of my car. The pump is not working well and can't circulate water, which leads to the rapid rise of water temperature.
4) Go to the 4S shop for inspection, because it is a new car within the scope of claim, and you don't have to pay for it.
5) I can tell you the cause of the failure, but you won't know what the problem is until you check it in the 4S shop. The reason for the cooling system is: 1. The belt of the water pump slipped. 2. The fan belt slips. 3. The water pipe is deflated or aged, resulting in internal blockage. There is something wrong with the thermostat. 5. Excessive scale deposition in the water jacket leads to blockage. 6. The water distribution pipe is not smooth. 7.9. The cylinder gasket burns through. High temperature gas enters the cooling system.
6) Other system problems: 1. The ignition is too late. 2. Carbon deposition in the combustion chamber. 3. The mixture is too thin or too thick. 4. The engine oil is insufficient. High water temperature is a problem that every car will have. The key is whether the cooling system is good.
