Yesterday, a buddy and I were out driving, I guess you could say, faster then normal driving. We did a few pulls, up to about 5.5k, and I noticed a coolant smell, so we pulled over. After opening the hood, there was white smoke coming up from around the rear of the engine. We look upon closer inspection, and notice that I blew the coolant hose going from the heater core to the hole that is between the two valve covers at the very back of the engine, we also notice a sound that resembles boiling over. So we tighten it back up, limp it back to my house, fill it back up with water and coolant, as well as the overflow tank, and all is well. However today after I drive my car, my overflow tank is already getting a low read warning from inside the car. So I filled it back up, and I'm worried that this could be a possible BHG. What can I do to investigate this matter?
