What is the normal coolant temperature for a car?

The normal temperature is indicated by the center of the needle--90℃. Here are specific details about coolant temperature: 1. Coolant is an essential part of a car's engine. It circulates within the engine cooling system, carrying away excess heat generated during engine operation, allowing the engine to run at its optimal working temperature. 2. Both excessively high and low temperatures can cause damage to the car. Lower temperatures indicate stronger heat dissipation. Excessively low temperatures mean greater heat loss through dissipation, and lower working temperatures result in higher fluid viscosity. Increased viscosity leads to greater resistance in moving parts, reducing output power. 3. Excessively low cylinder wall temperatures prevent proper formation and combustion of the air-fuel mixture, increasing fuel consumption. The engine becomes harder to start, operates with greater resistance, and fuel evaporation becomes difficult. Unvaporized fuel due to low temperatures can wash over cylinder surfaces, damaging the lubricating oil film and accelerating component wear.
Speaking of coolant temperature, I've been driving for over 30 years. Normally, it should be around 90 degrees Celsius, with the temperature gauge needle pointing right in the middle. If it's too high and exceeds 100 degrees, the engine might overheat and smoke, potentially ruining the machine. If it's too low, below 80 degrees, the car will lack power and consume more fuel. During the hot summer months, extra attention is needed. If the radiator is dirty or the fan isn't working, the temperature can easily spike. Once, I had a coolant leak on the road, and as soon as the warning light came on, I stopped immediately to deal with it. In winter, the temperature rises more slowly during a cold start, but it should reach 90 degrees after a few minutes of driving. As for maintenance, I check the coolant reservoir every quarter to ensure the level is between the marks. If the color changes, I replace it with new fluid and never skimp by adding water. Developing these habits can significantly extend the life of your car.
