My car is a 99 and was running very hot too. I did the simple coolant flush method on renntech and It runs much cooler now. I have not gone over the 190 or 200 line on the gauge. BTW is that mark between 180 and 250, 190 or 200? Less than 2 hours work, but so worth it!!!!!!

It is impossible for your engine to run as cool as 180 once it is warmed up. Like I said, The gauge us wrong.

Thanks for your help with the fan mod suggestion by the way 1999, That step is this weekend. It is just too hot here.

CHANGE YOU COOLANT TANK RESERVOIR CAP FIRST!!!
If it hasn't been changed in two years, more than likely this is your problem. The cap is a critical part of the cooling system and if the relief valve is opening at the wrong pressure, you car will overheat. It only cost around $20. I change mine every two years because this left me standed in the desert one time.

Unless you are losing pressure, a new cap will not do anything but cost you money. To test it if any part of the system is leaking, including the cap, remove the cap approximately 2 - 3 hours after running the car and see if it is still holding a vacuum.
Anyway, a pressurized system does not make the system any cooler or hotter than if it was not pressurized. All it does is raise the boiling point of the liquid.
