Has anybody ever used thermo fans on their 60s instead of the standard fan.
 
Hello,

Are you talking about using electric fans in place of the OEM mechanical fan? IF so then yes...a number of folks have done that with mixed results. When looking at the related write-ups its important in my view to understand how the truck is driven/operated (off-road or no), does it have A/C installed and operational..and what kind of temps does the vehicle operate.

Here in the states...a common swap is the dual fan setup from a V-6 ford contour, the large fan from a mark VIII, and also ford tarus. Some folks have run the dual fan setup that SPAL makes.

I'll post up a couple of links to the related threads if this is what you are looking for information on...electric radiator cooling fans?

I'm curious. What would be the benefit?

I can see mounting an AUXILIARY electric fan, say, on the front of the radiator, for extra cooling when running at crawling pace, at low engine RPMs, in hot places.

But it's not like the fan really adds a lot of load to the engine, and , efficiency-wise, I'd guess that the added load on the stock undersized alternator, (and, hence, the engine) would be worse.

I spend a lot of time in hot places with my FJ60, and, even with the AC running and running at a max speed of 5 MPH (at an event where that is the speed limit) for long periods of time, it has never even gotten warm, as far as the temp gauge reads.

So I am curious as to why one would want this.
 
well everyone has their own preference.

Clearly the OEM mechanical fan setup outperforms just about anything.

I never had an issue with my stock I-6 execpt had to replace the fan clutch one time...ice cold a/c and would run with a/c on anywhere and idle all day without issue (summer time).

Went to a V-8 and run the GM fan and fan clutch & fan because nothing else works as well.

If you use thermo fans you might be able to have a little bit more power because the engine isn't trying to turn the large standard fan.

They put so little load on the alternator that it isn't really noticed and I have a larger alternator than standard.

Yes my truck does have the air conditioning but I have disconnected it. Yes I am talking about electric fans instead of the mechanical fan.
 
The only thing that I can add it's you can't beat reliability on OEM fan setup .. so if you decide to go that route, I would recommend you always keep your OEM setup with you ..

Yeah I will because it isnt really big so I can keep it in the draws
 
I think you need to stick with the stock setup, the fan moves alot of airflow around the engine compartment, given that you have the extra heat of the turbo there as well, I think that electric fans are going to be the cause of some problems. The electric fans, even with shrouds never seem to help dump out as much of the hot air from the bay as mechanical ones do.

I'm gonna give it a try to see how it is like then I might change it back to original if it's needed.

my advice would be keep your toyota OEM cooling setup, make sure your radiator is in good shape, install new thermostat, gasket and seal, replace fan clutch with OEM and make sure fan and fan shroud are in good shape...you'll be good for the next 100K miles. The power saved by using electric fans will not be worth the effort. Read that threads and or search through the forum.

All the standard stuff is fine cause I have replaced it not long ago I just wanna see how these go and I can always put the old fan back on its an easy swap. I bought one that had been made for a hj60 I'll add a pic of it soon. It isn't the neatest looking thing but along as it does the job for a while then that's all that matters.
 
A few pics of it. Don't judge by the looks of it.

One of the problems with those types of fans is that they don't allow good airflow at highway speeds. so they cycle on and off even when you are cruising. I hated that about my electric fans. I also was not happy with the reliability. Mine were done pretty well and I had several small issues that caused overheats. Last thing was the noise, they were loud.

They do draw quite a bit on the alternator. especially if they move a lot of air... I think people underestimate the draw actually.

Try it and see, you may love them.

I'm thinking of running them full time when the engine is running so they always are having air flow. Im not to stressed if they are loud because there isn't a quiet thing about my 62.
 
I remember seeing an 8-blade fan on somebody's website; mine is only a 7 blade. Am I missing out?

I think the markets where A/C was not an option had a fixed blade fan which might have a minor different configuration.

Do the math and make sure your charging system is up to the task of running those fans full time.

If those things pull 20 amps you'll need a 240watt alternator to keep from starting to run batteries down.

Hell, even if they pull only 10 amps, that's 120 watts.
 
I really wouldn't bother with electric fans. Moby on this board lost his 62 in a fire due to the fan wiring.

The stock set-up will out-perform the electric fans. If you want more air movement from the stock fan put higher viscosity fluid in the clutch.
