What is the normal temperature displayed for car coolant?
2 Answers
The normal temperature displayed for car coolant is between 80 degrees Celsius and 90 degrees Celsius. When the car engine is operating normally, it requires a certain working temperature. Temperatures that are too high or too low are not conducive to the normal operation and performance of the engine. On the other hand, the heat generated by the engine's operation is difficult to meet the demand with conventional air cooling. Therefore, water-cooling heat conduction design is widely used in car engines. The function of the cooling system is to keep the engine working within the most favorable temperature range, thereby improving the engine's power, reducing engine wear and fuel consumption. Both excessively high and low temperatures will have adverse effects on the engine's operation.
After driving for so many years, the normal temperature gauge usually hovers around 90 degrees, and the needle resting in the middle position feels the most comfortable. With my old buddy, even if the needle is slightly off, it's still acceptable as long as it doesn't jump into the red zone. It's normal for the water temperature to be low when starting a cold car, but it should reach the middle line after driving for five or six minutes. If the temperature shoots up during hot weather or traffic jams, it's likely an issue with the fan or coolant. I once experienced a stuck fan, which almost caused the engine to overheat. It's best to keep some coolant handy in summer, and if the water temperature seems off, pull over immediately to cool it down.
