Do you have list/links to all the stuff I would need?

Thanks for the advice, I don't have a mod'd fan clutch, so maybe that is a good place to start.

Yes, by far the best value in performance cooling mod

Use the blue female crimps to make the electrical connection of the fan. The is not available form Toyota or any other aftermarket company I could find. If you cut the plug off the fan for another type of connection you have voided the fans warranty. The crimp connection is solid and will last.

I used the follow wiring diagram for hook up. The fan runs at ~7amps and a relay is not needed and will only reduce reliability. I used a Toyota factory switch rated at 21amps that will fit several factory blanks. The switch will fit in near the dimming panel on the dash left, under the radio, and will replace any of the coin slots in the center console. Always fuse any addition electrical accessory closes to the power source as possible.

Wheres a good place to secure the fan switch, All I found was a 95 dollars OEM switch

if you take a close look over my turbo timer, between rear AC switch and sub tank switch ..

To be honest having spent plenty of time on the Islands this will not do anything for you given if you have a mod'd fan clutch.

THIS!!

I have the JDM fan and although it worked ok with the stock clutch, it was a waste of money after modding my blue clutch

 

[RFB]

Oh man, ran a little voltage to the aux fan and it works perfect, boggles my mind why anyone would UNDO such a effective mod. well got an OEM fan button on the way Ill wire it up and move on to the next task.

one question left, what size fuse betwixt battery and switch

one question left, what size fuse betwixt battery and switch

For aftermarket fan, the volt should be printed on the fan, you then size the fuse. I'd buy a Blue Sea fuse panel and go off of that.

Motor loads are fused at 125% of the rated amperage.

so two more things phil Im putting that switch I got from you into the coin slot perfect fit. on this denso fan it HAD a 12/24v relay(little two bolt deal) the above diagram shows hot from switch to fan and neg from bat to fan. Do I circumvent the relay deal as I dont see it in diagram and to be clear motor load is say 100v fuse it with 125 volt fuse(hypothetically)

First
Voltage is the power source that pushes electrons, aka current
Amperage is the strength of an electric current measure in amperage

If your fan motor states 100v is will not work because you are working with a 12volt DC power supply

You want to look at the motors name plate and look for a measurement in amperage or wattage. Also look for a voltage number

Example #1- name plate shows 60 watt 60/12V = 5amps * 1.25 = 6.25amps there is not a 6.25amp fuse so you would use a 7amp

Example #2 - name plate shows 3.2amps 3.2 * 1.25 = 4amps no 4Amp fuse so you would use 5amp

Hope that helps

LOL, I was being hypothetical, and again does the 12/24 relay need to remain. should i run the fused hot from switch into relay into pos fan?

 

[LandCruiserPhil]

Depends on the fans amperage. The switch you now have or will soon have is rated at 20amps so anything aux fan rated under 20amps would not require a relay.

Take a pic of the fans specs and post it may be an easier way to the correct answer

I stand corrected....

Nice write up and pics. Did you go through all that work, and not bother to clean the outside of the condenser, trans cooler, and radiator?

Thanks
The install pics were taken from over a years worth of pics at different times for installation purposes. With that said you will be hard pressed to find a cleaner 80 that is used.

Ok so I was planning on doing the Fan Clutch Mod.. would this be a better option or do both ??

Fan mod always first. No other mod will benefit your cooling system more.

Aux fan helps control your water temp and keep your AC blowing cold during low speed wheeling, sitting in traffic, if you have a SC, or just sitting parked with AC on.
