Electric fan - $100 (Wonewoc)

I have a barley used Derale dual electric fan for sale.
It measures 28 1/4" W X 17'H It has less than 200 miles on it.
It worked fine with stock exhaust manifolds but when I put headers on the truck the fan does not run frequently enough to keep components cool, i.
e.
starter, power steering pump, fuel pump.
Water temperature is perfect at the Thermostat temp.
I have the instructions for it
