Is a Coolant Temperature of 90 Degrees Normal?

[ElianaMarie]

Coolant temperature of 90 degrees is normal. For traditional engines, the normal operating temperature range for coolant is between 80-90 degrees, while for high-performance engines, it is normal below 105 degrees. The engine coolant temperature should neither be too low nor too high; it needs to be within a certain range. The normal temperature is typically indicated by the central position of the gauge at 90℃. Below is relevant information: Coolant Temperature Sensor: It is installed in the engine block water jacket or coolant pipeline, in contact with the coolant, to detect the engine's coolant temperature. After receiving this temperature signal, the ECU adjusts the fuel injection timing and ignition timing. Winter Antifreeze: To prevent the coolant from freezing after the car is parked in winter, which could cause the radiator and engine block to crack, the coolant's freezing point should be about 10℃ lower than the region's lowest temperature, in case of sudden weather changes.
