* The engine temperature gauge randomly goes to full red
* 90% of the time it goes back down to normal all by itself in a matter of seconds.
* When the temperature does go all the way up, the a/c blows warmer air.
* Sometimes when the car is shut off, you can still hear the fan spinning (before the car was silent upon being shut off).
I don't know that the above are interrelated but they seemed to all occur around the same time. Also, the water level is fine. Any insight would be greatly appreciated.

Thank you for the responses and yes, the "check guages" light comes on.

You probably have a thermostat sticking and causing the engine to overheat. The reason the A.C fails when this occurs is that the PCM(car's computer) is turning off the A/C so that the engine gets all the cooling, and there is a lessened load on the cooling system. Helps to save the engine.
Does the light on the dash "Check Gauges" come on when this happens?
If the car has been worked on, there is the possibility of a poor connection somewhere in the engine compartment, and it isn't really getting that hot, just telling the PCM and the instruments that it is.
Check the Thermostat first.
Good Luck

Sticking thermostat. The fan blowing after the ignition is shut off is just the computer trying to cool the motor if the coolant is somewhat warm. Take the thermostat out and put it in a pot of boiling water to see if it opens. It is a cheap part and couldn't hurt if you replace it. 'Failsafe' t-stats have a simple valve in them to allow coolant flow if they get stuck, but all this does is prevent overheating until they can be replaced.

I would have to agree with CowboyBill. It does sound like a sticking thermostat. When you have it replaced, have it replaced with a Failsafe thermostat. When these thermostats go out they automatically stick in the open position to keep from overheating the motor.

Sounds like a sticking thermostat unit.
