My temp stays around 195*

 

Thanks! Mine sounds like a crop duster about to take off! Would make the change if it was quieter.

An under drive pulley for the fan would be a larger diameter and would spin it slower and the exponential increase in fan rpm versus engine rpm would be less too. The old 5.0 crowd used them for a cheap mod.

 

And a 6.4 fan DWARFS a 6.0 fan.
That thing must move a ton of air more!

Almost nobody runs a fan around here, even towing in the summer.

 

I know you wouldn't want to suggest the idea that its okay to run without a fan. It looks like the reason it works for you is the elevations in the state you live in. I don't think it would work well for those that tow and live in areas with higher elevations,

 

Can the 6.0 electronic clutch be operated separate from the computer similar to a torque converter lockup switch? And will this electronically operated clutch fit the 7.3 water pump?

 

You need the bigger fan to naturally cool the engine when the radiator blows

6.4 fan is really loud, engine is quiet though, so that probably has an effect.

I would say the 6.0 fan is equally as loud as the 7.3 fan if not a bit louder. I can't say that from experience of running a 6.0 fan on a 7.3, but I have definitely heard both fans running quite a bit.

 

To each his own.

 

I'm with you Rich. My fan stays on. It never gets driven in the cold months, just hot ones. I wouldn't mind trying the 6.0 fan though.

Jim: To each his own is always the option we are just sharing information / ideas that others may find interesting. (key word may)
When I posted I was just trying to relate how elevations where people live, drive, and tow the most, could relate to their decisions to remove the fan or not. I may not have been very clear on what I was trying to say. This is just a comparison, the state of Ohio has the highest elevation of 1,549 ft and a low of 455 ft as is fairly common in the Midwest. On the west coast the elevations usually are much higher, Washington State highest is 14,417 ft and the lowest is sea level. Towing here could be very inconvenient to say the least if you have over heating problems, although our trucks have a fantastic cooling system and as much as I would like to remove the fan I think it would not be a very good plan for me. The 6.0 fan could be something I would like to look into. Getting rid of the stock clutch and fan sounds like it could be a good thing.

Recently had to replace the water pump, thus had to remove the original metal fan blades and clutch, followed a few online threads about replacement with the 6.0L plastic fan blades. No one listed a part no. for the replacement, and several cautioned that a used fan might break apart and destroy the radiator. Several posts, presented their observation that the fan blades hit the radiator when installing. Well, they did not rub on mine, are about 1.5" away from radiator when fully installed, directly bolted to the existing fan clutch.

Purchased the blades from Rock Auto, was for a 2004 6.0L F250, SPECTRA PREMIUM CF15107. Took at least two lbs. off the clutch/water pump shaft/seal. No negative effects, cools the radiator/engine. Installation was so much easier, also, make sure the belt is off the water pump pulley, so you can spin it and thread the clutch/fan assembly on very easy.
