Cooling Fan on 64 Sedan Deville

[Robert Joyce]

Good morning all,

I am a new member to your chapter...exited to be here.

I posed my question to Jason in an email, but figured I would ask the group for their insight also.

My 64 was a non ac car and I will be installing a Vintage Air Magnum system.  I got the original motor mounts from Caddy Daddy and a new A6 style compressor from Old Air.  I am questioning what to do with the cooling fan.  From my reading on the forum, the non ac cars had a different fan setup (4 blades compared to 5 with a clutch fan).

What would you recommend ---

1. Install an electric helper fan against the radiator.

2. Replace the 4 blade with a clutch and 5 blade.

3. Replace the 4 blade with a 7.

Also, should I add a schrod?

Thanks in advance of your responses,

Bob

 Bob ,I would install a seven blade fan , second choice would be a five blade with a good clutch.

A fan shroud is always better than no shroud. Shroud with a fan clutch and 7 blade fan.

Is there a fan clutch that will work with the 7 blade fan

Logan, Another member named Greg on here, Used a new Hayden severe duty fan clutch & a 1968 six blade Cadillac fan ,and stated it cooled his 1964 Fleetwood very well. But it also has a fan shroud . As Russ stated you need a fan shroud also for best cooling.

Currently, I have a 5 blade with clutch and shroud. And I have a severe duty clutch and 7 blade fan from 1964 as well. The severe duty clutch did NOT fit the factory 5 blade fan.
