A little over a year broke a radiator fan blade on the G8 soon after having a Homer moment. At any rate, the V6 calls for two different fan blades, 92191939 (nine fins) and 92191938 (seven fins). The cost for the nine fin blade is slightly higher than the seven fin blade. Therefore, could the broken nine fin blade be replaced with a seven fin blade with no adverse side effects? Both radiator fan blade motors have identical part numbers. Theorized, since the V6 is much smaller and doesn't require nearly the cooling capacity as the V8, two less fins shouldn't make a significant. Understand the aerodynamics and flow of air is different between the two blades. THANKS
