check for leak at heater hose connections, near the firewall. Also check to see if the coolent is coming from the heater case. If so you probably have a leak in the heater core.
You can also turn on the defroster if you get a sweet smelling mist on the windshield, then
it is most likely you have a heater core leak and you would need to replace it.
you can bypass the heater core , til u can fix it and u wont have leak, hard to defrost windows though
