Smelt antifreeze when I turned on the fan...

a quick fix is to bypass the heater core by "looping" the hoses on the water pump. then you can at least drive it

Make sure you use enough hosing so that it loops smoothly. You don't want any kinks/pinches in it.

Heater cores are relatively easy to change (especially if you have done it before). Of course, non-AC cars are easier.
