In a word, YES! If your vehicle is overheating, serious and costly engine damage could happen. When it is safe to do so, pull over to the side of the road and turn off the engine. This will begin to let the vehicle cool down. DON’T try to test the radiator’s fluid level, which is red-hot and can cause serious burns. We advise drivers to have their overheated vehicle towed to the nearest, trusted auto repair facility.
