Overheating, and the cool fan turns on as soon as you crank the engine.(No the a/c compressor is Not turned on) In the morning I would turn the car on and its the first time I have driven it that morning. So the temp gauge isnt at the 3/4 line its at cold. But the engines cooling fan still turns on, what could be the issue for my this specific type of car? (94 Saturn sc1 coupe)

Sounds like a coolant temp sensor issue and possibly its connector being corroded its really common on those cars for those two issues. Its going to be the bottom sensor with two wires going to it a yellow wire and and a black wire. Do you have a multimeter to do some testing?
