Its a 2.2 Engine Automatic if that matters.

It will drive fine but if I drive it for more than half an hour it heats a little. I check the radiator fan and it doesn't spin so Im wondering if it kicks in at a certain temp(it should if its running hot). If my sensors are messed up or if its the radiator fan itself. Im buying a code scanner soon but until then, what do you guys think the problem could be?

 

What do you mean by heats a little? Is it overheating? The code scanner will only work if the check engine light is on. The fan only comes on when engine reaches a specified temperature.
