Electromagnetic fan to electic fan conversion

Post by lapuwali » Thu Jan 05, 2006 3:02 pm

I have a '69 124 Sport Coupe, which still has a 1438 in it. The electro-fan clutch is dead, and the fan is wired to run all the time. I can't find the electro-fan in any parts catalogs, so I'm assuming it's NLA, so I'd like to just replace it with a regular electric fan.

Removing the old fan is no problem, though it looks like the pulley is actually attached to the fan clutch, not directly to the hub, so I guess I'd have to keep at least some of the clutch in place. This really restricts the clearance between the radiator and the end of the pump. The skinniest fan I've seen for sale is about 2.5" deep. I could mount the fan off-center and it MAY work, it may not.

Anyone out there done this conversion, or can offer any advice on which fan to use, or which parts I can swap out to expand the clearance?

Have you tried our vendors such as C.Obert, Bayless, Bruce's Parts Bin, IAP or Vick Autosports? Many of them have an online catalog you could view these items at, or sales staff who would be happy to answer questions over the phone.
Good luck!
P.S.- do you have a good manual? I have an old manual that covers your model; I will look in there to see if there is any info I can find for you on that old fan.

I haven't seen one of those, but I would suggest that you change the water pump and pulley to be the same as the early spiders with electric fans (1970), and then use the regular Fiat Electric fan with shroud. Jon Logan (jonl1968@hotmail.com) has plenty of the used shrouds and fans, and may have the pulley, but I wouldn't suggest putting on a used water pump.

Again, I haven't seen your set-up, so I may be way off base here.

Dear L,
I hope you found the info you needed. My old manual has limited info in there about the fan specifically, but there are a couple of diagrams that may help. If you want them, E-mail me and I will scan them to you.

Thanks. The solution I've settled on is to use a 1608 water pump and pulley. This eliminates the stock fan and clutch. An aftermarket electric fan will go on the front of the radiator as a pusher, as even with the stock fan and clutch removed, there's still very little clearance between the pulley and the radiator. There's loads of room in front of the radiator, however.

Sounds good. I know in the IAP catalog they claimed one of their new modern fans would move more air volume, and we all know how hot our Fiats tend to run.
