Default Electric fan conversion

So, I intend to ditch the parasitic power tapeworm we call a fan clutch in favor of an electric fan on my 3.6
I haven't done any measuring yet bit was wondering if anyone else has done it and what size fan you elected to use. I did the conversion on my trailblazer and it was good for 18whp and about 2mpg and was a great difference in how the motor pulls. I used a Flex A Lite 16" syclone S blade and love it. Much less amperage draw vs most Mishimoto units and I control of through a Flex A Lite radiator probe controller. Works like a charm.
So I guess I'm wondering what size you guys used?
If this hasn't been done I'd be glad to make a DIY for you guys.

I'm betting this would be a great fit

100% to Doug.

A VERY long time ago, my daughters 3.6 spat a fan, normal scenario.

I was in the midst of converting 3 of my V12's to twin thermo fans at the time. Hardest part of that was/is getting all the old junk out of the way.

Daughter spotted my "spare" fan pack, Australian Ford Falcon 1996 onward vintage, and fitted it herself in about 3 hours. Hers had a thermo switch in the radiator for the small electric fan, and she simply used that switch for one of the fans, and wired the 2nd direct (via a relay) for the a/c only.

While she was at it, she removed the transmission cooler from the radiator, using an aftermarket unit out the front, and also the power steer, using a smaller aftermarket coil. This then freed up the radiator to look after the engine only.

Still running sweet today.

Nice, looks like a nice setup. I've never done one of those. I've always done universal fans with the "through radiator tie mounts" and run a twist knob probe controller that goes between the radiator fins and you twist the knob to the desired on temp. I wire a 20a inline fuse for protection. I'll post a pic of my trailblazer setup

Here was my latest E Fan project last fall. Don't mind the zip tied intake, long story.

This below picture is a custom set of helper battery cables because the OE ones were rather small.


The fan itself and all that extra room


This shows my fan controller, finds temp via radiator probe and I cleverly mounted it on the extra plastic on the washer tank.

The choices and possibilities are almost limitless.

Years ago I set up two e-fans on my XJ6, one big, one somewhat smaller. Using various bits from others cars (details long forgotten) I was able to conjure up a four stage operation: both fans off, big fan low speed, big fan high speed, big fan high speed with small fan.

Amazingly it all worked! But when I went thru my "concours" phase in life I ditched it all.

Anyhow.....

Using the X300 all-in-one two-fan assembly would probably make for a nice appearance and you already know that the fans have enough capacity to cool the engine...as that part has already been engineered for you. The price is certainly right ($89.00!) and OEM e-fans generally live much longer than aftermarket types....in my experience.

Just my 2-cents

Thanks Doug, I'm gonna look in to those and for that price I'd be crazy not to.
