If you have the car window(s) open or the car air conditioners on, turn them off when you get cold. If none of the things listed above are turned on in the first place, turn the heat on. If you don't have any car heaters, perhaps you can buy a coat somewhere.
turn the heater on...
Your car's operating temperature should be 192 degrees.
yes, should never add coolant to cold engine
In a car with a properly working cooling system, the coolant temp should be around the same whether the car is idling or running. There should be little variation. The car should warm up to that temperature quickly after a cold start.The temp would depend on your car make and sometimes engine size and characteristics. In general, however, it should be a little lower than boiling. For example, the normal operating coolant temp on a jeep grand Cherokee is 210 degrees Fahrenheit.
If your car running less then 10 minutes then it's considered a car with cold transmission fluid (fluid should be in the region of cold level marks, but not lower), if more then 10 minutes then it's hot (fluid should be in the region of hot level marks, but not higher). When you check transmission fluid level your car should be running.
In temp vs out temp should be about 18 degrees different if running top notch.
no you shouldn't because the cold air that your engine sucks up can quit your engine and stop running
That's a classic symptom of a sticking thermostat.
Your engine should be cold ( to be on the safe side) when adding antifreeze/coolant. i let the car sit overnight and then add it.
That depends on what the car is supposed to run at.
lets you know from inside the car if your engine is running at the proper operating temperature.
Normally your dipstick has a hot and cold mark on it. If not check it hot, always check it with the engine running on an even surface.
Depends on the ambient air temperature, humidity level, and type of refrigerant used.
