Never remove the radiator cap or expansion tank cap of an overheated engine as it is pressurised and could lead to severe steam burns. If you do open the cap once the engine has cooled, open it slowly and cover your hand for protection.

Should car engine be hot after driving?

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.

Does driving slower keep engine cooler?

When you're driving, the normal airflow will cool down the coolant in the radiator. However, when you're driving slowly or sitting still, the fan keeps the air moving so that your coolant can still get cooled down.

Should I stop driving if my engine is hot?

If your car is overheating while driving, you should not, under any circumstances, continue. It can cause extreme damage to the engine and even lead to a fire. Pull over if your temperature gauge starts to tick up too high.

Is my engine ruined if it overheats?
