Question about 1999 Chevrolet Malibu
I have the same exact car and had the same exact problem when i bought mine. I would check to see if it is a head gasket becuase that is the problem that i had with mine, but with that i also replaced the water pump and the thermostat and things have been okay so far so i would check into that.

Before you spend any money on fixing the heater core or the car, block off the lines for the heater and try running the car. I'm very suspicious that you will need to do more than fix the heater.
To block off the heater, you will see 2 hoses going into the firewall from the engine. Unhook them from the firewall and either plug them with a large bolt and clamp or use a plastic elbow from the hardware store to join them together and bypass the heater.
If it still overheats then you should prbably take it to a shop and have it looked at but I'm guessing you will probably have to do some serious engine work. Hope this helps.
