Need a new fan

[Gyrodoc]

Does anybody have any experience Mac's 4 Blade fan P/N Part #: 28-24689-1
Looks like it would be easy to remove when changing water pump. Pros and Cons would be appreciated

Stay with the aluminum type 2 blade. JMO

The 4 blade does NOT move more air.

[Del in NE Ohio]

Neither does the six-blade plastic

You don't even need a fan over 35mph anyway.

I put the plastic fan in my rig right after the 4-blade fan that was in there lost the rivets holding it together and took out my nice radiator. I just figured that the plastic fan would be "kinder" to my new Berg's Radiator.

Too nice a Model A to fit with a cheap looking plastic fan ....... two (2) blade aluminum looks far more original & appropriate.

The aluminum 2 blade gets my vote as well. Works very well, and is quiet. The plastic fan is OK for a Model A that has V8 wheels with radial tires, alternator, and other hop-ups. Doesn't look quite right on an otherwise original looking Model A.

+4 for the aluminum 2 blade fan. As mentioned, it looks original and is one cast piece.

Buy the 2 blade aluminum it out performs the others looks proper and is quieter. .its easy to change the pump if needed.. If you do go with plastic keep the hood shut

They have been all coming through true.... Very well made

Tom W has a balancing rig, the ones he tested were good

I had one exactly like that one shed a blade are take out my radiator.

[DougVieyra]

It sounds like the two-blade ALUMINUM fan gets the most votes. Are there more than one manufacturer of the 2-blade Aluminum fan ? Does anyone know who (Parts Dealer) makes them ? If there are more than one manufacturer / source, which is the better ?

At the moment I am still quite happy with my original 87 year old original steel Ford-made fan. BUT after all these many years of service and age, this thread has made me nervous.

Knowing that often times there are a number of reproduction items that have a 'run' made and then the source dries up, I thought I would purchase the best aluminum fan I can get, NOW, and store it up for later use - if needed.

[Tom Wesenberg]

Snyder's makes the aluminum fan, and they sell to other parts houses.
If I change out my original fan, it will be a new aluminum fan.

[tbirdtbird]

pay attention!
dump that 87 YO fan now

would you drive on 87 yo tires? no. why? because they will disintegrate! same for the fan!

[DougVieyra]

tbird: "dump that 87 YO fan now"
-----------------

Oh, ye of little faith ! . . . ."Would you drive an 87 year old car?"
. . . well, yes I would. Yes I do.

But there are SHAYs out there for those who prefer them to driving an 87 year old car. I just prefer to drive my 87 year old car, as long as it is serviceable and safe. And I would not be averse to using 87 year old original tires - as long as they are safe and serviceable (I have not found that to be the case, so I don't use them).

I have however, found a source for original air from 1928, which I have in all six of the tires on my 1928 Phaeton ! I know that it is stale, and perhaps musty, but it still is serviceable and safe to use. So I do.

I just had my original 4 blade fan develop some stress cracks and lose rivets. I caught it before it did any damage to the radiator. I purchased the 4 blade fan from macs and i am running that now. Hindsight being what it is and after reading a few fan related threads i probably would have went with the aluminum 2 blade one. My thought on the 4 blade was that is what my car had and it seams to stay fairly cool so i stuck with the 4 blade.

[tbirdtbird]

"I just had my original 4 blade fan develop some stress cracks and lose rivets."

LOL what is your point LOL!
there are posters here that are determined to tempt fate and have a fan blade go thru the hood no matter what the consensus !!

and we are all driving 85 YO cars; just not all using the dreaded 4 blade fan

So what are you going to do now that you have stired up the hornets :-)

[Mitch//pa]

There was another study that showed the 2 blade pulled more air.... I think it was from Bob Johnson????

The text on the pictures above are to small to read on my iPad .....

Looks like 2 Blade aluminum is the way to go. Since someone said you don't need a fan over 30 miles per hour, who gives a rats how much air a fan moves?

If some genius would come up with a clutched fan for the Model A we could move air and gain horse power too.

[CarlG]

Bill Stipe modified a "Flex-A-Lite" fiberglass fan to fit a Model A. Theory is that the blades flatten out at higher RPM's, therefore not using any HP to turn them.

If you want to be able to remove the water pump and fan without moving forward the radiator you can use a water pump mounting kit sold by Snyder (A-8501-MBM) $5.50 for the set. These bolts are machined to look like the original studs & nuts. These are one unit bolt and stud, so it makes it easy to remove pump and fan.

The original fans can brake at anytime so the aluminum fan is the way to go. They are balanced and powder coated. In our club we have at least two members that the original fan got impaled in the hood and caused a lot of dollar damage. After seeing this I changed the fans on my 3 Model A's. This is peace of mind.
