Hello: Sounds like you are low on coolant. Top off the system then watch for leaks.

The fan will run after the engines has been turned off. The temperature gauge at 2/3...It normal when the engine ran for two minutes then turned off. It could have been hot day, air conditioner is running, stop and go traffic, drive really slow. many factors affect the temperature of a engines. One way the manufactures fix some of this overheating problems were to install axillary fans, also increasing the psi on the coolant system from 212 degree F, to 240-5 degree F. Buy doing this the half water/half anti-freeze will not boil off. Just make sure that the bugs are removed from the front of the radiator and the air flow isn't restricted. GB...stewbison

Turn ignition to run engine off. Display OIL LIFE RESET in the Driver Information Center (DIC). Press and hold the ENTER button for at least one second. An ACKNOWLEDGED’ display message will appear for three second or until the next button is pressed. This will tell you the system has been reset. Turn the key to OFF. If the “CHANGE ENGINE OIL” message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure.

The second fan helps cool down the system with the a/c on. I would start the car get it to operating tempature then turn on the a/c. With in a few minutes the second fan should come on.
