Good morning, I have a 2005 Chevy Spark 1.0LS and my cooling fan stopped working. We manually checked the fan by connecting it to the battery and it still work. We also replaced the relay, I have noticed that the little car seem to use more water then usual and it would seem that the Radiator cap seal has done its time, however it would seem that the Temperature sensor that control the cooling fan has gone. I dont have an engine diagram and would like to know where it would be located
