1996 Cadillac Seville V8 Front Wheel Drive Automatic

The coolant is leaking into the front passenger side floorboards, I have to refill it every few weeks. The A/C works fine and I don't use the heat, am in Florida. What could it be, is it expensive to repair, the car is in fairly good condition for its age so this will determine whether to fix it or sell it.
Thank you

Replace the heater core. It is behind the right side dash.
U will have to open the a/c case. Then remove the
heater core. U will have to remove the 2 heater hoses that go to the firewall. Replace if needed, also
check the valve for any type of seepage. If u need the car or short
of money u can block it off to stop the leak. I just
stick spark plugs in them and secure then tie the hoses
to prevent them from damage good luck
