Hey guys

Was getting an auxiliary fan for the Tacoma (Toyota part #88590) and thought I'd get one for my 4runner too. The dealership catalog didn't show any such fan existed for the 4runner from Toyota.

Anyone have any experience with this? Any before/ after experiences or aftermarket suggestions? Hoping for something direct fit n good quality as the heat here is ruthless.

What are you trying to accomplish with the aux fan? I live in Phx and the 4Runner seems to do well in the summer (105+ degrees)
 
105+???

I guess, it's only Spring. The really hott shizzle is in July / August. :banana::banana::banana:

1. help improve the ac circuitry cool things down a bit.
2. not have to pop the hood open after half a day in the sand at 130+ degrees

Does your 4runner have any other fan on it besides the main one attached to the engine?? just trying to figure out if my canadian version differs from az (or warm weather) spec as the sometimes do. The AZ taco came standard with a trans oil cooler if i remember correctly.

I do know all our prados here come standard with extra fans on them to help with the heat

Mechanically the Canadian and American 4Runners are the same. Toyota seems to be doing away with their hot/cold climate packages and just making any extra cooling/heating functions standard fare. I did some looking around and I can't find any OEM auxiliary fan for a 1GR-FE 4Runner.

Could you post some photos of the Tacoma auxiliary fan and how it installs in the Tacoma? I couldn't find any images on the world wide web and I'm curious. Have you tried mocking it up to your 4Runner?
 
Trust me, Phoenix does not get as hot as the Middle East...

What he said. I used to live in Arizona and spent time in Kuwait, Jordan, and Iraq. Kuwait is orders of magnitude hotter than any of them.

OP: How well does your 4Runner's AC deal with the hellfire weather in Kuwait?
 
Also, have you considered louvers? 4wd Toyota Owner magazine say they saw a 35 degree drop in the engine compartment of an FJ using Run Cool louvers.

Very true, did my BS at ASU and summers were warm, but not to what we call hot.. as in, your palm trees do not seem to randomly catch fire..

Will upload the dealer printout on this when I get home.

We're still in late Spring, so *just* approaching the 105-110f mark.. will let you know in a few more weeks.

Trans / converter temps in 195-205f range on highway with medium traffic, even with constant hard gas/ brake action (as in most middle eastern traffic)..

A/C starts to struggle a bit in stoplights with traffic. I've been tracking a few readings with the Torque App:
The "Evap fins target" is set at 36.4f when the AC control is set to "Max AC".
The "Evap fin" readings manage to stay in that range in the shade.. but after a few mins under the sun I hear the fan clutch constantly coming on and readings would start to creep up to ~42f. Air out of the AC vents is not too bad at this point, but I'm worried it won't be able to keep up once we really hit summer.

Also, have you considered louvers? 4wd Toyota Owner magazine say they saw a 35 degree drop in the engine compartment of an FJ using Run Cool louvers.

Looks promising, but don't really want to go that far if I don't have to. Hoping some fans and a good ceramic tint would pull me through!
 
Maybe add a large transmission cooler, that may reduce some of the heat load for the engine cooling.

We are stuck with the low capacity air conditioning in our 4Runners.

Thought I'd update this post with my findings so far.. Pics included

Got the fan installed. Idea is to have it run only when A/C Compressor is running. Seems wiring was routed back into a relay in the fuse box, dunno if they added an extra relay for it, but it works so far. Only funny thing is the *click* I hear from the fuse box every now and then. A/C isn't any colder, but now seems to get there quicker and maintains decently cool air in traffic as well. Guess this is as good as it'll ever get for the 4Runner.

Also figured out 4Runner's temp gauge maxes out at 50C (122F).. It's been brutal this year, and am sure we've had warmer days than 50C last July.
