Dual Fans - Vintage Air - ProFlo-4 ECU

[Richard]

Agree with the previous post. Also note when running two fans it is very inefficient to run only one fan unless there is a divider between them. If an open shroud between the two, a large amount of air from under hood will just be recycled instead of being pulled trough radiator when only one fan is running. Air will follow the path of least resistance which is through the non running fan. Reducing speed on both fans at first call is a better option. Yes, running just one fan may work for some.
