it will overheat all the way up to the red line and I do have a check engine light, but the light did not come on. I was told that the two fans in the front are not working and that while I am driving enough air flow is cooling the coolant. I just checked and the fans will not come on regardless if the A/C is on or if the engine is hot. they will not come on period. I was told they are supposed to come on with the A?C regardless of the engine temp. The AC does not work either.
