Steam coming from underneath the hood of your vehicle may mean that


Steam coming from underneath the hood may mean that the cooling system has overheated. Pull over to the side of the road and turn off your engine immediately. It's a good precaution to carry extra coolant or water in your car to add to the radiator, but only after it cools down. Modern cars typically require a 50/50 mixture of coolant and water, so pouring only water into the radiator may lead to the engine overheating again eventually. If all you have is water, add it to the radiator, but also add coolant as soon as possible.

In the midst of finishing up learning on the older app, it told me to download this newer version. However, I didn’t want to have to go through all those questions again, so I simply finished reviewing on the old app and took the practice test on this newer app. Upon completion of the tests, it would not let me move forward or see my score! How should I know if I have done well enough to pass if I cannot see my own score?
