Good Day All

I will like to install an Auxiliary Cooling Fan to turn on with the Air conditiong Switch.

I would appreciate anyone that has installed one to reply with brand, part#, and instructions on how to install it using the Air Conditioner for the vehicle.

I would prefer a fan that I do not have to modify.

Thank in advance.

I used the 16 inch fan from oreillys. I forgot the cfm but it definetley moves some air. mounts direct to radiator and you can set it up as a push through or pull through fan. around 50 bucks
 
Do a search for the ABC's of cooling. JDM aux fan can be used as well as a variety of similar size fans if you want to fab up your own mounts. Wiring to trigger with AC is also discussed.

Do you still have AC in your truck? Because for the life of me i could not get one to fit in between the ac condenser and the rad! Sorry not meant to hijack the thread

Only way to install one without much modification and fit like a glove is to install a JDM 80 series aux ac fan. ;)
 
perfect timing i wasn't sure if the 14 would fit. was going to get a 13" but 14 here we go.

my need is because i added an inter-cooler and can't get the air flow i need for A/C cooling. i would suppose some one with a stock front in slow traffic may need one for low RPM/low speed cooling additions.
 
If you piggy-back an aux fan on to your AC clutch wire and your battery is low, it will melt the coil in your clutch. Or at least it did so on the 92 many years back. I would run it with a separate switch/relay like we did after that misfortune or even better, mod your fan clutch with 15k cst silicone oil and don't worry about it.

I ran the auxiliary fan because when I got my LC it was on the neglected side and was running an O'Reilly flex fan and no shroud. It couldn't keep the temp down when pulling long steep trails

How much will this lower temps, ballpark? Like 5-10* maybe?

An aux fan will not lower engine bay temps.

They are added to assist with AC performance in slow/hot situations like traffic or busting along a hot dusty trail like Dusy or the Rubicon.

I have never register a lower engine temp due to an aux fan in the PS position. I've been running the JDM Toyota fan for over 8 years.

Do you recall how much if any of the necessary wiring is already in place? I see there’s a spot in the under hood fuse box.

None that I recall. I installed it to a rocker switch in the truck. Went through an aux fuse block I had set up.

I know the way Toyota sets it up is that it's connected to the AC system and a sensor will engage and disengage the fan as needed.
