What should the temperature be when the cooling fan is turned on?
The cooling fan should start running at approximately 230° F (110° C), which usually happens after 20 minutes of engine operation. If the cooling fan doesn’t turn on, it will lead to overheating. Compare the temperature of the engine head, near the thermostat, and the upper radiator hose.
Why does my car temperature gauge go up and down?
If the Temperature Gauge Goes Up and Down You may notice that your temperature gauge reading goes up and down, fluctuates in some kind of pattern, or is erratic. There may be several reasons for this: Low coolant level delaying thermostat opening and closing (check coolant level in the radiator).
