Start with the obvious. Check the radiator and heater hoses under the hood. Heater cores usually leak into the passenger compartment with a strong antifreeze smell in the car. Loss of fluid means no heat transfer to the heater and, the engine can overheat due to the lack of coolant. Repair the leak(s) and replace the coolant.

Check the hoses for sure like Goldstar suggested. Heater cores usually drain into passenger floor but sometimes they have a drain going through the firewall. But, they usually do not produce a huge puddle.

Antifreeze is a very POWERFUL smelling chemical. You could have a few drops of this leakin in the engine area, and it will be smelt in the vehicle.

I suspected a burst coolant hose or fitting.

I had an ,87 Plymouth Sundance 2.2 Turbo (cousin to your car) and the heater control valve at the firewall under the hood are known to crack at the hose fittings.
The valve is located on the passenger side of the engine compartment at the firewall and has 2 hoses going in and 2 hoses going out.

You don't want that valve to crack when your on the road because it will dump all of your coolant.
It's plastic and they don't cost that much, about $ 20.00 bucks.
Easy to replace.

By the way that 2.2 non turbo motor is bullit proof.
It will run forever. Also had a '86 Dodge Omni 2.2.
