I have replaced the Radiator, Radiator Fan Motor, the switch, relay, thermostat. While driving (in Florida, kinda hot) With AC running, its not getting cool. and i am watching the temperature gage rise. When i accelerate (prior to replacing the Radiator Fan motor) the temp gage will drop down. Now after replacing the fan motor, when the gage rises and i am able to accelerate, its lowers very slow. I have checked and there is coolant in the Radiator and in the reserve. The Ac motor is on.. and when the car senses the correct temp, the radiator fan comes on like it should.. With both fans on, it still is over heating. What am i not looking at/missing? Anyt Ideas or suggestions?
Wait till the engine is cold, remove the radiator cap, start engine and look for coolant gushing out of radiator or a lot of bubbles, its possible you have a blown head gasket.

You need to check the water pump and thermostate.
It looks like either thermostate get stuck or water pump died.
In a future it can cuse the head gaskette to die due to overheat
So have it checked
There is one good article here about the common reasons for overheating

hi.
the sensor is usually located on the side of the radiator. it is usually a srew in unit with 2 wires coming from it. just remove the wires, unscrew the old one, and screw the new one in and reconnect the wires. if you are lucky, you should not loose more than a cup of coolant either.
hope this helps
Thermostats will stick sometimes. Most are made to open at certain temperatures. In some cases brand new thermostats fail. Try replacing it its pretty cheap probably no more the 10-15 dollars for the part it self its an easy fix also.
