Q: Radiator fluid bursting out behind engine what's the problem

It is very possible that your heater hoses could have sprung a leak. The heater hoses are routed behind the engine normally because they must be connected to the heater core which is inside the dash. Therefore these hoses are routed towards the firewall. If the heater hoses are leaking, the fluid would be leaking from behind the engine itself and close to the windshield. I would recommend having your vehicle inspected by a qualified professional to determine the exact source of the coolant leak. Consider YourMechanic as inspection such as these can be performed at your home or office.
