What is the normal coolant temperature range for a general car engine?

[MartinLynn]

When the engine is cold and just started, the coolant temperature is the same as the ambient temperature. After 3-5 minutes of engine warm-up operation, the coolant temperature will rise and gradually enter the working temperature range of 75-98 degrees Celsius. The specific working temperature range depends on the vehicle model or driving style. Here is some relevant information about coolant: 1. Coolant serves functions such as antifreeze, cooling, corrosion prevention, and scale prevention. Although coolant also contains water, this water is soft water, specifically distilled water that has undergone deionization and softening treatment. If the car engine coolant is insufficient, soft water can be added, but attention should be paid to the amount added. It should not be added excessively, as this would alter the boiling and freezing points of the coolant. However, hard water such as tap water should not be added, as it can cause adverse effects. 2. When it is found that the car engine coolant is insufficient, timely replenishment is the best solution. Regularly check the remaining amount of coolant. If the coolant level is below the minimum mark, it indicates insufficient coolant, and it is recommended to replenish it promptly.
