Given the 6 cyl, the 18" fan, 17118, should be fine for the 6cyl vs the 19" 17119. Less rotating mass.

I have yet to have any cooling issue with the fixed 4 blade here in SoCal summer....although a cutch fan would reduce fan noise....turning up stereo can do that to :-)

Not sure of an overall length of the fan clutch so a spacer may be required to keep the fan same distance as the fixed 4 blade is from radiator. The 6 cyl just has a top safety shield vs a "shroud".
