I need to order an electric fan ASAP for Clarkson. We are putting a brand new OEM radiator back in and going with electric fans. Right now, I’m looking at a a 4000 CFM set of fans with less than 50 amp draw, which we can address.

Any quick recommendations or thoughts?

Anyone want to throw out a better radiator I could snag from Amazon?

 

I have heard that this fits with minor modifications on the factory rad: https://www.summitracing.com/parts/der-16927.

The Nissens radiator is a popular OEM-type. Allisport is all aluminum, but expensive and they didn't have any in stock the last time I heard. I am planning on a custom-made radiator from Griffin the next time I have to go into that.

 

Why you want to go electric with the fan?

I have one and plan to go back to stock.


No power or mpg gain and one big flaw…

if your alternator dies that fan will eat your battery in about 15 minutes. Not good if you ever plan to leave civilization.

 

I was thinking about using one of these, measurements seem about perfect, and they come with a PWM controller: https://www.summitracing.com/parts/der-66826

What fan set up do you have Dave03S? You running a Derale or Flex fan kit, or more like a DIY setup? I've got a brand new heavy duty clutch fan setup I may be willing to trade with...

 

I disagree about no MPG or power gains. I have historically noticed a roughly 1mpg gain switching to an electric fan.

I like using these, but they're getting a bit harder to find. They work killer. Tons of CFM because they have to pull through those tiny Ford grilles. Can usually be had for around $75 or so, and the shroud is generally built in.

 

If you are planning to get that far away from things, then I would say that you need to carry a spare working alternator regardless if you are using an electric fan or not. These rigs need a substantial amount of electricity to run. Without an alternator, it's not going to take long to run out of juice just to run the fuel pump, ECUs, etc even without the additional load of the fan. Could always hook up a switch to turn off the electric fan in case of issues or water crossings.

The biggest cooling advantage is that you can get max CFM from the electric fan while at idle and completely turn it off while cruising on the freeway. There's plenty of reasons why so many OEMs are now using electric fans.

 

thanks brother but nothing will change my mind on electric fans. It’s going to happen.

 

I’ve looked at that very fan and presented it to my local shop. Evidently it draws a lot of amps. He said he’d like to see less? I’ve found another Derale that has fans that run under 300 watts and also pushes 4000 cfm at less than 50amps.

 

Also just thinking about a combo with 3 core aluminum radiator with fans…
