"overheating"
My Car Is A 1994 Firrehawk #497 Of 500
Recently In The Past Few Months Ive Been Having Trouble With Overheating Issues. Ive Flushed The Radiator, Changed The Water Pump Twive, Changed The Temp. Sensor Twice, Had The Heads Resurfaced As Well As A Valvejob, Changed The Gaskets Eliminated The Heater As Well As The A/c. And I Cant Go Five Mile Cause My Temp Gauge Goes Up To Between 3/4 And The Red Area? I Also Had A Mechanic Check The Radiator Pressure And It Didnt Go Over "0" Lbs. I Have Also Bleed The System. What Could It Be?????????

Re: """ Over Heating""
How did you bleed they system? You have to fill it up cap it off let it run till it gets to operating temp then open the thermostats bleed screw and you will hear air escape then you open the radiator cap and fill it up until you do not hear anymore air coming from the bleed screw. Close it and run it some more and then open the bleed screw back up and repeat the process until no more air escapes. Remember to put a towel or rag under the bleed screw because you do not want any coolant getting on the opti. If you have the heater system still in then you also need to bleed that with its bleed screw at the same time your bleeding the thermostats bleed screw.
If you didn't follow this procedure than your system is not bled properly and that is the cause of your over heating.
also put your thermostat in a pot of boiling water with a cooking thermometer and see if its opening at 180 degrees. If it does then its fine. I would replace that thermostat as it slows down the water flow in the system allowing the water to "absorb" as much heat as possible. I've had people come to me asking for a new radiator because there car was overheating and the only cause of there car overheating was that they removed the thermostat and it was letting the water flow too fast to provide any decent heat exchange.
Also your cat could be stopped up and needs removal or replacing. Crank it up at night and let it run for a few min and open your hood and if you see your exhaust manifolds glowing red. If they are glowing red then your cat is stopped up.
*edit* I noticed that you said that there cooling system is not pressurizing. This leads me to believe that you do have air trapped in your system and that is what is causing your overheating issues. The system should pressurize. Try bleeding it the proper way and reinstalling the thermostat and see if that fixes it. If it doesn't check for clogged cats with the method I mentioned above. If there fine then I may lean to the Clogged radiator side.
How Often did you change the coolant?

a few years ago I had an overheating issue. Turns out the radiator got "clogged" per say...nothing a flush would do, but only like 1/3rd of the radiator was cooling the engine. New radiator and all was good.

I'ld just buy a 160 degree thermostat and you would be done that is what i did to my stock LT 1 and it never hits half way on the temp gauge also turning on your A/C will kick on your fans this should cool it right down.

with the system not pressureizing the thermostat isnt the problem. he either has air in the system or has a clogged radiator could be causing the overheating as well but im leaning to the air in the system
