my 93 town car is leaking coolant from somewhere around the firewall on the passenger side, under the car... It also is blowing smoke and a coolant smell through my vents.. any ideas??

Well either the coolant hoses on the outside of the car are toast. Or your heater core is gone.

In addition to what ltdltc said, replacing that heater core is going to be a big job for any car, Town Car is no exception

If you plan to do it yourself, get a Shop manual first.

Your heater core is shot... Before it leaks inside your car you should put some Bar's Stop Leak in the radiator. This is a temporary fix, so plan to cahnge the heater core within 6 mo. or so... You can get it at any Autozone, Checkers, etc. for cheap...
