What is the normal water temperature for a BMW?
1 Answers
BMW cars have a normal water temperature of 90°C. Here is a detailed introduction about the car cooling system: 1. Temperature: The engine coolant temperature should not be too low or too high, but must be within a certain range. The normal temperature is the center position of the gauge, which is 90°C. After the vehicle starts, the antifreeze temperature rises rapidly. Once the pointer reaches the center position, the heat exchange balance ensures the antifreeze temperature no longer rises. Generally, it is optimal to start driving when the temperature reaches the middle position, which is one of the reasons why it is necessary to warm up the car before driving. 2. Cooling system faults: Generally, cooling system faults mainly include liquid leakage, insufficient coolant, radiator fan failure, and circulation water pump failure. When a car engine operates normally, it requires a certain working temperature. Neither too high nor too low is conducive to the normal operation and performance of the engine. On the other hand, the heat generated by the engine is difficult to meet the demand with conventional air cooling, so water cooling is widely adopted in car engine designs. 3. Function of the cooling system: To maintain the engine working within the most favorable temperature range, thereby improving engine power, reducing engine wear, and fuel consumption. Both excessively high and low temperatures will adversely affect the engine's operation.
