That said, were originals 6 finned like below, or 5 ? I've seen some and can't tell.

If it is not an original, I may be interested in replacing it with an original as part of the engine rebuild so if anyone has one going let me know. thanks.

Ps - i put some rust removing gel on the center casting in case you noticed....

There has been much discussion about the issues with the original 5 blade fan. If you are determined to use a Ford replacement fan then read thru what Steve AKA Secluff and others wrote in a couple of posts ... https://www.7173mustangs.com/thread-chec...=D9AZ-8600

"There was a massive recall because of blade fracturing in early 1972 and remained active through the early 80's. Since all the fans have engineering numbers on them, I'll just list them and not the part numbers. These are the most commonly used 5 blade fans: DOAE-A, D1AE-CA, D2SE-AA, D3OE-AA, D4OE-AA, D6OE-AA, D7AE-AA, D8OE-AA, D9AE-EA. Unfortunately there was also a problem with some of the replacement 5 blade fans fracturing. So the easiest and safest solution would to be to use the D9AE-EA as it was in use on a lot of later models such as the 79-91 Crown Vic. It was also a service replacement for all the ID #'s I've listed above and was the fan listed for the 73 302, 351 AC Mustang in the final issue (Nov 88) 73-79 Master Parts Catalog. Part number for the D9AE-EA fan is D9AZ-8600-A"

thanks all, this is all good info and I would like to replace fan at some point, is it a priority ? probably not.

I did try and search for this topic to avoid reposting, but it appears google does a better filter on searches than the forum as i found more detailed info from an earlier posting on this site ! after i posted, so in future i will check that first. These cars keep you on your toes...

Rich, with all the fan blade related postings, I had almost forgotten about posting that one earlier. Never had a problem with either of my 71's since they had the DOAE, D1AE style fans. Of the three Gran Torinos I owned, two were Q code cars and had the 7 blade fan. My 429 powered Torino had a 19 1/2" clutch fan and was not involved. The 72/ cars were running leaner, emissions controls, NOX and later EGR systems were adding to the cooling system load. The 7 blade fan was an attempt to pull more air through the cross flow radiator. As Geoff will tell you, looked good on paper, but was a disaster out in the field.
If you want originality or have a show car, use the D9AZ-8600-A fan (Motorcraft YA-153) . It was the final "Fix" fan and replaced ALL previous versions of 5 and 7 blade flex fans. It was the OE fan on my XR-7 Cougar and remained in use through the 90's. Due to previous experience with my Torinos, I inspected the blades very carefully on the Cougar every oil change. Never had any problems with that fan but did respect it, especially with the hood up and engine running. Green sales does still show three of them.  DO NOT risk your safety with a used one!!    http://www.greensalescompany.com/

For a daily driver or if originality is not a concern, I would take Hemikillers suggestion and go with a clutch fan. They are quieter and take the load off your engine since the clutch disengages the fan when not needed. I hit the books and found a clutch fan setup for the 79-91 Police Interceptor that used a 18 1/2" fan and worked great for my setup.

Or an electric fan from a Taurus.
