I have a 93 ford taurus 3.8L V6 automatic GL. I had my car up on ramps the other day to change my oil and filter when I saw drips of antifreeze coming from the bottom of my catalytic converter. I knew before that I had a antifreeze leak because my coolant reservoir has to be refilled completely ever couple of weeks. I could not find where the leak was starting. I inspected my radiator, all hoses, coolant reservoir and water pump. They were all leak free. I thought it was possible the leak may be coming from my heater core or maybe a freeze plug. Can antifreeze leak from your catalytic converter and if so is this a sign of a leaking head gasket?
