Radiator misters system

[gm4106]

Hi All
I want to try to build a radiator water mist system. I am trying to cool my bus while pulling hills.  One question is what size nozzle would I need? Also how many and how far apart would I need for a radiator 32x 33 inches?  Suggestions. 
Thanks

Check with NAPA  hayden makes a kit that truly mist.

A lot cheaper than cobbing one up  check hayden web site

comes with pump and holds about 3 gallons of distilled water
