Why has coolant exploded all over my engine?

So, I noticed something was weird with my car today. I pulled over and checked under the hood. Turns out, the coolant exploded all over the place. What would cause that? And what should I do now?

There are a couple of possible causes for coolant exploding all over the engine. The extent of the “explosion” is very important.
Many drivers describe it as an “explosion” when their coolant system develops a leak and spays fluid everywhere. If the explosion you’re referring to was much more literal, you may have blown your head gasket—especially if you were noticing overheating issues beforehand.
In either event, you’ll need to do the same thing: have your car towed to a mechanic. The main difference for you will really just be the cost of the repair. If it’s a leaking coolant system, a quick and cheap patch should sort things out.
On the other hand, if your head gasket is blown, you could be looking at extensive engine damage—and thus expensive repairs.
