Author's Note: Top 5 Signs of Engine Trouble

I mentioned in that last tip that no one could possibly be so ignorant as to let their car run out of coolant. No one but me, that is. My first car (when I was 17) was a Chevy Chevette. I knew nothing about car maintenance, having only a vague idea about oil changes being somehow necessary. I certainly didn't know about checking fluids, or paying attention to the temperature gauge in the dashboard, or what to do when any warning lights came on. When hot, white smoke billowed from under my cheap hood, I learned very quickly about the price of coolant ignorance. It's expensive to replace an engine, even in a crappy car from the 80s.
