Ron decided one afternoon to take his dad’s car for a spin despite just learning how to drive one and despite the snow that was building up. As was taught to him, before he drove off, he checked the engine oil and refilled the the cooling system with water. But after an hour or so of driving the car, he noticed the engine was having a problem. He popped the hood to see that the water he had refilled had started to freeze. What went wrong?
He did not include a coolant in the water used to refill the cooling system.
A coolant is an antifreeze, which it lowers the freezing point of water to prevent it from freezing during cold weather.
