You may have a bad radiator,or your head gasket has blown.

Could be blown head gaskets. Also, it's an older vehicle, so the engine could just be bad.

The thermostat shouldn't be removed for overheating unless it has failed to open at proper temperature, your cooling system doesn't benefit from removing it, you may have other issues such as clogged rods in the radiator or plugged and clogged water jackets in the engine as we'll, prolonged driving while overheating the engine will cause major damage such as TST and Ares26 have stated.

When thermostat is removed and not replaced, your radiator doesn't function as designed, it keeps coolant in the radiator to be cooled until the thermostat opens to allow coolant to cycle properly.
