electrical fans

Is it worth it to install the electrical fans or just leave the factory one on?

It reduces engine drag but might require a larger alternator. I think I'm gonna eventually switch mine to an electric one.

I can't answer the trouble of how to hook them up is but I love mine. It is so much easier working on certain engine parts when you get that extra few inches of shroud and fan clutch and all the other items removed. I ran a ford tauras fan with a stock 75 amp for a few months untill it died out.

They are not too bad to hook up. See the Useful Info thread and go to Very Useful or Old Fuel Injection websites for diagrams.


You can get an SN95 Mustang, Taurus or almost any Ford/Mercury/Lincoln car/truck electric fan and fit them to your Mustang.
I prefer using the Ford/Mercury/Lincoln fans because you can get replacement parts for them easily if you need them.


Couple of things to note though, I have found that most diagrams leave out the need for a high amperage relay and a one way diode to keep the fan motor from spiking your electrical system when you turn it off. Those electrical spikes can damage or destroy other electrical components, so be sure to install the diodes.


The main fan power relay should be a 70-75 Amp unit to handle the start up amperage draw of the fan motor. While the fan motor may run at 20-30 amps, the start up amperage can spike way past that. Using a smaller amperage relay will lead to replacing it sooner and more often because the over current start ups weaken it each time the fan starts.
Using just a direct wired switch will not work either the high current draw will burn them up with alarming frequency.

If you are doing road course,auto cross, or strip only you might want two. If its just a DD with spirited driving and occasional strip use one should be fine. A better cooling system upgrade would be an aluminum radiator with more rows IMO

It's pretty much a weekend warrior/ show car in progress and I just got a 3 row radiator

As long as they can move 2500-2800 CFM of air it does not matter.
A fan(s) with a shroud on it will do a much better job of directing the air flow.

I haven't found any that move that much not even on AM or LMR highest I found is 2200 CFM

They are out there, see dreamstangs link.
2200 CFM would probably work ok on a stock to mildly modified SBF engine.
For a higher performance engine you would need more air flow to keep it cool.


I ran a 2200 CFM fan on a mildly built 429 BBF. It worked ok until I started playing with it, then it would heat up. I changed it out for a 3000 CFM double fan with a custom shroud and didn't have any further problems.

Performance cooling can make really nice aluminium shrouds for the fan you order to fit your radiator at an affordable price.

what i think it means is it comes with a water sensor and will kick on at a certain temp.simiar to the fan controller that i was talking about.im not sure if that one is adjustble though.

Yes, that means it comes with a thermostatic control to turn the fan on and off.


Look it up on the manufacturer's website to see if it is adjustable or not.
That looks just like a "Black Magic" electric fan I had years ago.
If it works as good as mine did you will like it.

Looking at the picture of it enlarged, on the top that looks just like the control on my Black Magic fan and it was adjustable.

It's adjustable, I have that exact fan. I didn't have any luck with the thermostat control and ended up running an external thermostat.

Quality must have suffered when they were bought out?
Mine worked perfectly.

I bought mine based on the reviews that I read, I took it out to take the electronics out and mount my switch in the original spot on the fan. Haven't gotten around to re-installing it yet.

a pusher fan will mount in front of your radiator.a puller fan will mount between your rad and motor.you want the air moving towards your motor.so basically a push fan pushes air and a puller fan pulls air.

read above.trojan and slowstang both used it. and yes your gonna want a puller

Good answer!


I don't know about all "pusher" fans but in my experience the pullers move more air (CFM) and seem to do so using less amps than the pushers.


The Black Magic puller fan I had years ago worked great, right up until a telephone pole jumped out in front of me anyways.
Yes, I . All of my hard work destroyed in seconds.

Just do a Google search for the controller you want.


Depends on what your fan amperage is when it's running.
The 30 amp fuse is usually sufficient though.
I always oversize the relays to 70-75 amp because the start up amperage spikes pretty high and will usually do in a 30-40 amp relay pretty quickly if you drive it much.
