check your coolant levels. One time, some how the coolant disappeared from my resivoir when I was going to school. Next thing I know, my car is smoking with no coolant, don't ask me how. I filled it with water and as soon as I got home I replaced it with prestone.
That was very scary, every week now I check fluid levels to make sure they are fine.
