Q: We were driving yesterday on the highway and the check engine light went on. When we pulled off the road we found antifreeze all over top of engine like something exploded. What could this be?
A: It could be something as simple as a radiator or heater hose that has burst. Another possibility is a frost plug or engine block heater popping out. Or, it could be as complex as a cracked cylinder head, faulty head gasket, or damaged engine block causing the problem. Do not drive the car. The vehicle should be towed to your service center. Driving the car without antifreeze will damage the engine further.
