What is the reason why the water temperature of Chevrolet is rising too fast?
The specific reasons are as follows:
The cooling fan does not rotate. The cooling fan can be controlled by a temperature control switch; It can also be controlled by a water temperature sensor.
Insufficient cooling medium. (1) antifreeze: high-end cars are required to be filled with antifreeze all year round; ② Water or distilled water: temporary substitution; ③ The water tank cover leaks.
The thermostat is broken. (1) If the thermostat is to be removed, the small circulation should be blocked at this time to ensure that the coolant is completely dispersed by the water tank; (2) When installing a new thermostat, pay attention to the water hole, such as Santana, there is no water hole. At this time, a hole should be drilled with a 6mm drill. One function is used for marking; Another function is that when the car heats up, it will produce the temperature difference between the two sides of the thermostat, so that the thermostat can be opened accurately with the water temperature.
Water tank blockage ① External blockage should be eliminated by water or gas; (2) Internal blockage will affect the circulation of coolant and generate pressure at the same time. At this time, there will be two results, one is that the water tank leaks, and the other is that the water temperature is particularly high when driving at high speed.
The water pump is out of order. ① The timing belt is broken due to slipping or sticking of the impeller; ② Impeller deformation.
Cylinder corrosion. (1) When the combustion chamber collides with the waterway, it will drain water or discharge white smoke from the drain pipe, resulting in frequent water shortage in the water tank; (2) The waterway collides with the oil path (the oil with water is white); (3) The collision between waterways leads to poor heat dissipation of the cylinder block, especially at high speed; ④ The waterway is blocked.
Extended data:
Solution to high temperature of automobile water tank;
1, pull over, shift the automatic gear to P gear, shift the manual gear to neutral gear, pull the parking brake handle, and turn off the air conditioner.
2. If you find that the coolant boils and overflows from the radiator after opening the engine cover, please immediately turn off the engine and turn the car key to the on position. Do not start the engine again, and let the electric fan of the radiator run automatically to facilitate heat dissipation.
3. After cooling for a period of time, check the coolant, and then check whether the upper and lower water pipes and their interfaces are leaking or whether the fan drive belt is broken.
