Mounting electric fan to radiator

I have an aluminum radiator that will go inside a model A grille shell. Can you guys give me some ideas on how to mount an electric fan to radiator. I see those plastic straps but I have heard those are not that reliable.

What do ya say?

ur local parts store should sell plastic push pins that mounts thru the core. I have 2 electric fans being held onto my radiator with them...no problems yet!

I fab'd my mount after the stock camaro mount, there was a channel on the top and bottom of my rad, I made a bracket that locked into the bottom channel that stuck out far enough so that the shroud/mount would rest and be secured on the bottom, then I fab'd a plate that locked into the top channel and bolted to the top of the shroud..... these parts, fans and shroud were salvaged off a early 90's camaro

I just upgraded to dual electric fans. Not sure if it will help you much but this is what i did in my 70 elky. I used a piece of 3/4" angle steel and used 1/4" selftaping screws and went right into the radi support and into the shroud.

Totally different set up but it might give you an idea

Nothing wrong with the Plastic Pin/Ties, very durable. Can be a pain to remove tho'.

If your Fan has a Shroud that covers the complete Radiator it will work best with some space between the Rad & Fan.
Large Fans work best w/full coverage Shrouds, they're less likely to block airflow @cruising speed. "elcaminodragster"'s setup above is a good example.

You will never see electric fans mounted the same way twice. We take 1/2" x 1/8" steel bars and press set screws in to them. The bars are riveted to the side brackets or tabs of the radiator and the fan mounts to the screws rather than anything going through the core.
You will hear good things and bad things about the nylon push through ties. Fact of the matter is, yes they work for some, but have given others trouble. Custom brackets are easy enough to come by, so in my opinion, taking a gamble with the nylon ties isn't really worth it.

It's all in how you install the nylon ties. You have to use the foam tabs, and don't strap them too tight because nylon shrinks when heated up. I'm sure the people who have had bad experiences clamped the ties too tight, and with the heat shrinkage they snapped.

I personally never had problems with them, but I'd agree with using a more sturdy approach.

I know, I know, I'm contradicting the posters above - but, IMHO those plastic ties look like crap!!! Cheap!!! And unimaginative on a street rod. OK, use them on a street machine where you don't see 'em. Everything on an early Ford (or whatever) hangs out for comment and cricism.

Make a bracket like El Camino did or smaller ones like I did on my '31:



Tough if you have an a/c condenser also - you can see my brackets on the side radiator frame here:

Thanks guys. I believe I will be making a bracket for the electric fan. You gave me some really good ideas how to do the fabricating.

Right on Irelands Child! And I think you should be the first one to go to the Crankshaft Coalition Wiki and list your buildup under a new title of Electric Fan Buildups and Pictures.
