Almost 100% guarantee that a fluid hat is being pumped will result in
turbulent flow...a Reynolds number below 2000 is laminar and above 4000
turbulent, in between is the "critical zone".... Don't think there is
much engineering left in the design of engine radiators. A copper radiator
will transfer heat almost twice as fast as an aluminum one.
I live in lower regions of AZ --- at 120F ambient temperature it's too hot to
be anywhere outside. Best you can do for engine cooling is: make
sure the antifreeze mixture is correct, the water pump is operating properly,
the radiator is clean and no tubes are obstructed, straighten any bent or
damaged fins, make sure the fan shroud is installed correctly, the fan is in
the right position relative to the shroud, there are no obstructions to the
air flow, the radiator is paint black.. Then add rows or increase the
fins/inch -- after that you're into fan sizes and speeds and/or electric
fans.
