What temperature should my car run at in Celsius?
For most of the modern car, the normal operating engine temperature is in the range of 75 to 105 degrees Celsius . When it reaches 80-90 degrees, the thermostat allows the cooling fluid flow through the other cooling circuit. If the temperature continues rising, the radiator fan starts cooling the engine.
What is normal operating coolant temperature?
For most cars, the normal operating engine temperature is in a range of 195 to 220 degrees Fahrenheit , though most dashboard temperature gauges don't show an exact temperature. Instead, there are typically markings for cold and hot on the edges of the gauge and a normal range in the middle.
