I have a 93 ford taurus 3.8L V6 automatic GL. I have an antifreeze leak and as far as I can tell I think it is leaking from the heater core. I have checked every thing else. I would like to know if the heater core is leaking then does it have to be leaking from inside the car onto the carpet or can the leak be from under the hood on the outside? My antifreeze leak is hitting the top of my catalytic converter. Can the leak occur on the outside of the car or is it always on the inside of the car to be a heater core leak?
