Yeah, heater cores leak like crazy when they're kaput.

How hard is it to replace the core,
The core is under the dash, so it's likely to be a healty PITA.
how much does it cost,
no idea, call around to local auto parts stores, there's no special name brands you need to worry about.
AND most importantly... is there a way for me to PREVENT this problem until then??? Thanx
Yeah, don't use any heat. If worse comes to worse, put in a piece of generic heater hose connecting the heater core in and out hoses so that no fluid is directed into the cabin.
