Leaked out alot of antifreeze between the fire wall and the engine block

There are two lines - on in and one out - to allow coolant to circulate through your heater box. One of them has likely sprung a leak. The inlet to the heater box runs from the radiator and the outlet from the heater box runs into the engine block.

You can get a free loaner tester from most auto parts stores. Replace the radiator cap with the test cap, which has an air fitting on it. Use the air pump, with engine off, and pump up to about 10 PSI. Believe me, you will see exactly where the leak is coming from, where ever it is coming from.
