To add to the radiator that Scott pointed out:
From quick search at AutoZone.com:
THERMOSTAT\ufffd$4.99
WATER OUTLET GASKET $.99
RADIATOR CAP $4.99
LOWER RADIATOR HOSE $6.99
UPPER RADIATOR HOSE $5.99
4 HOSE CLAMPS and 2 GALLONS OF ANTIFREEZE ~$12
So you're looking at about another $36 worth of parts. Changing a radiator in that car should be a piece of cake, easily done in a couple of hours.
