Ok I have a 1997 sunfire and it is over heating.
1)Changed the thermastat same problem
2)Flushed the rad same problem.
Then I noticed the fan was not kicking in.
It did once for about 5 seconds then shut off.
So i wired the fan direct and it droped temps to below normal so I know that is my problem.
So where is the sensor located for my fan so I can replace it?
