My Jetta 1.8t is overheating. Im not driving the car right now, its up at NADC in nashville getting painted. My buddy thats painting it told me that on the way to school today it started to overheat, but tended to stay nearly the same at idle/neutral. He also told me that he thinks the radiator fan is not turning on, which is making me believe that the radiator fan relay, which if im correct is located under or to the side of the battery, has gone bad. Anyone else had anything simular to this. I really dont think it is the water pump, thermostat, etc because its not really overheating in neutral, he coasted halfway to class with basicly overheating when he was in drive. Any suggestions?
