Check to make sure the electric fan is engaging. There is a temperature sensor that tells the electric fan when to engage. Its driven by temperature for the command prompt. And, of course check your fan to see if it even works at all.. You can bypass the electrical system and jump the fan to make sure the motor isn't fried in it.

Make sure you fan is running in the right direction just solved my overheating issues cause my fan wasn't sucking in cold air thru the radiator it was actually blowing hot against the radiator easy to tell that put a paper towel in the front grill if it gets pulled in the grill fans running correctly if not then shut it off reverse the wires that power the fan
