Hello All,

OK, coming back from my previous studies and this thread (old thread) "electric engine fan ?? any idea" dated (11-09-2009) the link:
http://www.fjcruiserforums.com/forums/engine-performance/97243-electric-engine-fan-any-idea.html

and from my personal experience with classic GM V8 engines and previous E.Fan project, I have to clear many cons of the mechanical fan and to be realistic and clear E.Fan system is the best for every day use which is not less than 70% of the use of our trucks! (my self offroding on sand, dunes, dirt and some times rocks only a day every week or every two weeks!!)

So the list if the mechanical fan cons:
1- Every time you start your truck you have to notice that high fan noise (90`s like) and to feel its drag.

- When you are stuck in traffic or offroading or just stopping for more than 10 min and the engine is ON:
2- Radiator temp increase.
3- Intake temp increase (big time).
4- Trans fluid temp increase.
5- A/C don`t perform as it should.
6- Some engine power is lost.

Then lets see the Pros of the mechanical fan:
1- it break but after long life time of use.
2- If you your offroading is mud!

Alright, now after looking at the list above you for sure realised how wrong and out dated it is to use the mechanical fan! but we still have that person who thinks the E.Fan fails more than the mechanical fan actually for 3 years of using that old school poor design of E.fan on my 98 Tahoe the only thing failed (once) was one of the relays and other time was a fuse! thats it.

I well start the talk of the things (such as fan, relay...) but first I have to clear to you all (US FJC owners) something, as you can see in the image under there is a different size stock toyota radiator:

The US market got: 16400-31461 for (11/2010 - 01/2012) and 16400-31462 for (03/2012 - 06/2014)
The GCC market have: 16400-31351 for (11/2010 - 01/2012) and 16400-31352 for (03/2012 - 08/2014)

So here we go,

After studying the needed parts I ended up with the following:
1- Fuse box (OLS PSZACCEPS051H 6-Way LED Illuminated Blade Fuse Box with Cover)

2- Fan controller..
A1- Flex-a-lite Electric Cooling Fan Controls (I don’t know which one to choose)
A2- Flex-a-lite 398 Syclone Black 16" S-Blade Reversible Electric Fan.

B- Derale Adjustable Fan Controllers.

C- Volvo fan controller.

3- Inline Radiator Hose Temperature Sensor Adapter.

4- Flex-a-lite Trimline Universal Electric Cooling Fans.

Regarding the shroud, I well be using the orginal!

Any ideas??

I have also been pondering this idea. The only reason I am on he edge about electric fans is because I live in Washington state where water is a if part of our lives. Shorting is always a possibility. But to counter act that I would have a hardline switch installed just in case of failure. Have you decided on wat fan and what size you will use? And silly out use the factory fan shroud?

Makes sense - looks like the same bracket, just a much bigger core. I figured the GCC radiator would be bigger - I didn't figure the core would be double the US spec though! Probably explains why my temp needle doesn't move regardless of how hard I'm working my FJ or how hot it is!
