Ken last asked about his fan.
You REALLY need this book.
Appendix F is 'Fans, Spacers, and Viscous Clutches' - 12 full pages of fan details.
The Mustang Fans table lists 23 different fan possibilities in the years 65-69: Standard fans, HiPo fan, Extra Cooling Fans, A/C fans. You should have the idea by now that this guy is a detail fanatic.
There were 4, 5, 6 and 7 bladed fans. Let us see if I can figure out what yours was/is. I find nothing to suggest that P/S had anything to do with what fan you got.
BTW, yes, HiPo was a 4 blade, fixed fan.
However, sorry about that Extra Cooling 6-blade fan. All Extra Cooling fans were either 4 or 5 bladed. I think I have one of those 6 blade fans on my shelf that I put on my '68 (in '70) in a personal search for 'extra cooling' after I had added A/C to the car. I sold the car and kept the fan. Wonder what the new owner used for a fan???
If you happened to have Extra Cooling AND T/E for 66/67 you would have fan C5AZ-8600-A with FIVE, fixed blades. The table on the next page says that fan had 17" aluminum blades with a 5/8" hole in the center. The ID stamped on the fan was C5AE-B. You also got the same fan in a standard '66 T/E car without Extra Cooling. Sound familiar to you?? BTW, once you determine fan number there are 11 different design styles to visually ID the fans. If you want that detail I am going to make you buy the book.
No, I don't get any commission. No one does, Bob sells these out of his kitchen I think.
Sorry, radiators were not bolted to the engine, and this is an engine book, so Mannel does not give us any data on what an Extra Cooling, or any other type of original radiator might have been. I have revived old radiators to use since the new ones are not very original in their detail. Both of mine are 2-row but then neither of my cars had Extra Cooling.
