The very first thing you should be doing is get the car to someone with an OBD II scanner capable of real time data capture (PID); have them check what your water temp really is at before you puke something major.

You could have a bad dash gauge, temp sending sensor, water pump, externally blocked radiators, or dead thermostat; you need to start eliminating items one at a time rather than just swapping out parts……………
