yeah, me too. And I want to do the same with my LC.
That has been discussed quite a bit, and while there are advantages, the reliability if the stock fan wins out.....

My brother's truck has a new blue hub and a 14" electric pusher, mine has an older blue hub that has been tuned up with 10,000 fluid. Mine out performs his big time! I bought the same fan at the same time as his and have sold it. The tuned up blue hub works very well, can now sit in traffic at 115F+ and still have nice cold air from the vents.
If you have a supercharger, then everything changes. Due to the fan size, spacing it will never move as much air as a stock fan, even with an upgraded clutch. With the S/C adding the pusher is a good upgrade.

TRU, I wonder if your fan pushing that much air decreases your mileage?
Romer- IIRC, CDan has exactly the same setup and he said that his produced no significant coolant temperature decrease. 10F is huge! Are you sure the decreae is not due to the fan clutch changing fan speed or the thermostat opening? I have a 14", 3000CFM pusher fan installed and, while AC performance is much better, coolant temperature does not change according to OBD2. And I have verified that it is pushing air into the condensor and it is sealed against the condensor properly.
How did you measure this 10F decrease? Can you take multiple measurements with fan on and off and post them? Is there anything else you did differently from CDan to get such a great coolant temp decrease while he did not? I'll post some measurements from my setup soon for comparison.

I'm of the mind that most any vehicle manufacturer's OEM electric fan will be as good as any clutch fan, because when a car builder offers a 7 or 10 year warranty on a drivetrain with an electric cooling fan, he's going to put top quality parts and labour into the assembly of that fan to prevent warranty claims due to overheating.
If something like Ford's 19" Crown Vic (fleet/cop) fan or Mazda's dual fan from the older RX7 pulled enough CFM, I'd give it a try.
**Note: I don't live in a hot climate. Overheating, even when stopped in traffic for extended periods isn't an issue here.

Been running it for a year and if anything the mileage is slightly better.
I remember reading that after Dan "tuned" his blue clutch that the pusher made no difference. And at that point only opening the hood helped lower the temps.

I have not tuned my blue clutch, I will do that later. This was a sample of one as I just installed it. Driving in traffic stop and go, no AC. Turned the fan on and saw the aftermarket temp gauge go down, could have been coincidance, but I think a good part of it is due to the fan. I will run some more tests. I think Dan did his test with the AC on. I also know that if Dan doesn't turn it on in hot weather with the AC On, the temp goes up.
Dan is the one who recommended I get one. I wouldn't think he would do that if I wouldn't see any real difference. He told me about being able to sit in high heat with the AC blasting and the fan on not letting the truck get hot.
I agree.
If the stock fan clutch setup was so good you wouldn't need to "tune-up" the blue hub clutch. Nor would Toyota have put tabs on the vehicle to install an aux electric fan for some markets. The real question to me is, why didn't they make this an option in all markets?
CappyKD- the aux fan was included only for models with rear air and coolbox in order to provide additional cooling capacity for the AC system.
I believe the blue fan clutches are not the stock units. They have replaced the original ones. I had a nearly new blue clutch and radiator and overheated badly. The clutch was the fault and after tuning it it has worked flawlessly.
I would like to do this as well...but I think I'll just have the aux. fan engage only when the A/C is on. Any feedback regarding this method. Also, any wiring info for how to do this is appreciated. Thanks all...

problems solved daily...
I think Tools or his brother wrote this up a while back.
I'm planning on adding an aux fan. As hot as it gets in my area...if nothing else, it could be a little extra "insurance" if the fan clutch fails someday.

How long does it take to get the fan in once you order it?

I ordered from Cdan. He can tell you if he has any in stock and if not what the lead time is.

Oh good deal.. i thought he had to order all JDM products.. all the time, i didn't know he had any of that stuff 'in stock'.
I have sold enough of them through the years that my depot usually has one on hand even though they never existed here.
I've also purchased this JDM fan from CDan a while back. I'll get around to installing it when my job slows down later this summer.
This fan looks exactly like the electric fans installed on the other FWD Toyota models. The mounting tabs are different, but the motor and wiring looks identical.
