Check the heater hoses, they connect to the firewall connecting to the heater core inside the dash. Also might be a freeze plug came loose.

Nice one Tom I was going to suggest the same. TK, Make sure the engine is thoroughly degreased in the back, as well as the firewall. This will help you find leaks more easily. good luck.

TK, did you ever find the origin of the leak?

I surely would like to know since this is the EXACT SAME PROBLEM THAT I AM HAVING .. I just don't know what to do , except try and find the culprit and pray it doesnt cost a single mother ALOT of money
