Hi all
I'm planning on installing twin AU thermos onto the patrol and I'm after advise on how I should wire it up.
My first thoughts are to have a 3 way toggle switch, where I have either "off", "half speed" or "full speed" as the options. What do I need to run the fans at half or slower speed? Is it as simple as running a resistor in the loop?
Any advise on this is appreciated.

IMO and should be taken with a grain of salt.
Sorry cant' help ya mate, my dual thermos are wired to come on automatically when it a pre-set temp with an override switch to turn them on at will, I personally don't really see any need for a half speed.

No that helps a lot. I'm keen to know what other setups people are using as it helps me decide what to use. What are you using to automatically turn the fans on?

You can buy them off the shelf at repco, auto barn, supercrap also
* this is just an example

Lower speed will need a pwm controller. You can get them at jaycar.

If you have A/C will the A/C fan still be fitted?
If the A/C fan is being removed then you will want at least 1 of them to run when the A/C is running regardless of engine temp but you can use the existing wiring for that.
Don't bother bumming around with 1/2 speed or whatever, just set them up to run off a thermo switch with a toggle switch for either;
"Off" and "On" where "On" means they both run from the thermo switch and "Off" is for water crossings or really deep muddy crap.
OR
if you tow or don't do much water/mud work "Auto" and "On" which is how I have my auto tranny cooler fans setup
I don't recommend having a manual system and remembering to turn them on yourself.
You only have to forget once in the heat of battle and it can be major damage so use a thermo switch.
A warning light that the switch is "Off" can be useful as well if you go that way.
If you are doing this because you have overheating issues then you may be disappointed.

Mine came with the fans when I bought them from Davies Craig, but you can buy them separately: http://www.daviescraig.com.au/Contro...ches-list.aspxOriginally Posted by Parksy

Have you got an after matket cooler evil? And or a temp guage if so what temps do you see with the fan
X2,
Also with thermos makes sure you have a good customized shroud or you will easily find yourself with overheating issues

I have twin fan assisted tranny coolers for my 4L85 and I run an engine and tranny watchdog system that switches them on at 80 degrees.
I have a manual override switch so that if I am low speed wheeling or towing in hilly areas I can select them permanently on.
The watchdog will sound alarms at preset temps for the engine coolant, tranny temperature and also low oil pressure
