Where to look when the car is cold and when the temperature is high?

Wait until the car gets cold. When the temperature is high, look on the dashboard. If the water temperature is high before starting the car, it may be difficult to start the car. There are many reasons for the high temperature of the car. The cooling fan does not turn, the cooling liquid is insufficient, the water thermometer fails, and the water tank is blocked, which may lead to excessive temperature in the car. If the water thermometer is normal, it should slow down when the temperature reaches the red warning line. When it is safe, pull over and be careful not to turn off the engine.

Brief introduction of automobile temperature

Specifically, which temperature, the dashboard of the car will display two temperatures, one inside the car and one outside the car. Insufficient antifreeze. The thermostat can't open normally or is stuck in a fully closed state. Poor pumping capacity of water pump will lead to poor water circulation and high temperature. The cooling fan can't work normally at the water temperature, and the rotation speed is slow.

If the antifreeze is insufficient, check the leaking part and add it to the correct water level after repair. The water does not circulate, the thermostat cannot be opened normally or is stuck in a completely closed state, so it needs to be replaced. Poor pump capacity caused by poor water circulation may also lead to high temperature, which may damage the pump blades, so the pump needs to be replaced. After the water temperature of the cooling fan is abnormal, it is necessary to check the fuse and relay circuit or replace the fan.
