300 rad fan the same as 302? 300 rad fan removal?

Gents,

Does anybody know if the rad fan on a 300 is the same as a rad fan on a 302?

Friend of mine has a 1978 F100 with a 302 and regular (non-clutch) radiator fan. He wants to convert it to a clutch fan. His existing fan will not work obviously.

There's a 1983 F150 Bullnose at the local junkyard with a 300 in it, and a nice condition radiator fan. I know the clutches are different between 300 and 302, but are the fan blades still the same?

Next question is regarding removal. I did this before with my 1980 F150, but the truck is gone now. Can anybody remind me what size that nut is, and confirm whether it is right or left hand thread?

I made a bar to hold the water pump last time. Might have to do the same, so I want to be prepared if we go grab the fan. How do you hold the water pump from turning if you don't have a holder? I think I tossed mine after I sold the truck with the 300.

i do not remember about the cross reference but i know that i have three units on the shelf. where is he located? anywhere near mid tn?

Can't answer the question about removal, but there's a chance the fans are the same.  From our page on Documentation/Cooling Systems/COOLING FAN #'S & ILLUSTRATIONS I see that the '83 probably has an E3TZ-G and that was also used on an '83/86 302 w/o A/C.

The six cylinder has a reverse thread for the fan, Cory. With v-belts intact, one can usually hold the water pump stationary by apply pressure to the belts.

Excellent guys, thanks for the replies and confirmations!

Way up in Canada, east or northeast of Maine;).

Can you tell me the size of the big hex nut?
