thanks david, but i think my problem might be deeper than that...i'm still working on it though. it ran fine from school, but the damn thing is overheating. this i know for sure: the external fans are NOT kicking on. I'm currently working with my ALLDATA machine to find which (of the 4) coolant sensors control the fans. It is possible that the wires from the fan controlling sensor are shorting and not sending power to the appropriate relay. Problem is, my ALLDATA machine is not giving me what i want to know. I think I am going to post another thread for the techs...
