'95 saturn sw1 still runs hot!

[CJC]

as soon i noticed the temp rising i flushed the system and replaced the thermostat. not only did that NOT work but i noticed the radiator was ruptured a few days later and antifreeze was spraying right onto the air filter housing. i don't know if that happened before or after i flushed it. so i replaced the radiator thinking that was it but it still runs hot. what am i missing? water pump? any ideas?

thanks in advance for your advice.
