I recently was driving down the road when I heard a pop under my hood. All my instrument warning lights came on plus the car was overheating. After pulling over I found that my fan belt broke which pulled off the power steering belt, which broke off one of the fan blades. After I pulled over and shut the engine down coolant poured out from under the car from the back of the engine, steam came through the air vent, and the passenger side rear floor board is now wet. As I got under the car I could not see any hoses that may have blown off. Is there an overflow hose that I’m not seeing? Also as I was under the car in the back of the engine near the passenger side firewall I noticed a small ½” to ¾” hose nipple protruding from the wall, it there a hose the attaches to it?

Thanks

if coolant leaked from the back of your engine you might have cracked your head gasket...
