Want to know about factory fan operation
No mods that I'm aware of on my car.
From what I've been told, the primary fan is ECM controlled and the secondary fan comes on by the fan switch which I was told should come on around 238*.
What temp should the primary come on at? I think now it is approx. 231*.
