Boyz,
Its a current model vehicle fan, not sure, got off shelf in salvage.
Bingo, lookin back at my original post, saying to use a marine blower
I had forgot.. but
I really want someone to try this,, thinkin that it will work better and
save battery power, specially if you only run 1 battery.
I would tie the suction hose to the tub cellar., mount the fan coupling
where the old battery location was, and that would be it.
Quieter, less amps. and could run at all times,, enhancing the cold air draw
through the rad and also removal of extra hidden carbon monoxide in the engine tub.
