1993 Ford Tempo sounds like water running and I smell anti-freeze

The water running sound that you hear is probably caused by air in the cooling system. As the air and coolant go through the heater core, it will make the sound you described. The anti-freeze that you smell is probably from a leaky heater core. You mentioned that you checked the anti-freeze level and it was okay. Was this done in the radiator or in the over flow reservoir? The radiator should be checked, ice cold and clear full of coolant.
