Default ENGINE KNOCKING and BIG LEAK

Today I started hearing a hard knocking noise from my engine and knew it wasn't normal. I used to A/C for first time in awhile too. Then the engine tempature went all the way to red and so I quickly got to an auto parts store and got some anti freeze. I drove the car home and popped my hood to see all the anti-freeze everywhere: on top of my engin and everything. I started the car again and all of sudden the anit freeze and water started coming out very strong from the front of the engine by the round black dome on the front by the belts. It is coming out very strong and I can't make out where its coming from or what to do. Has anyone had this problem and a solution?

No offense, but it sounds like you need to have your car flatbedded to a shop.....I'm sure they will know what to do.

with Lucky. The fact that you didn't park the car immediately and simply add WATER to your radiator from the nearest source tells me a lot. Driving it when it's that hot to a parts store is not the best decision ever made. You need professional HELP.
