The Secret To ICE COLD AC In An 80 Series Land Cruiser! | Aux Fan Install FZJ80

Living in the desert proposes a few challenges to keeping any cars interior cool, and the 80 series is no exception. One of the ways I have found to mitigate this on the 80 is an 2200 CFM auxiliary fan install. Much like the JDM 80 Series, this fan is mounted in a similar location, but with a lot more airflow and some custom wiring. If you are struggling during the summer months, give this a shot. Relatively inexpensive and rather quick upgrade to the factory AC system.

I did the same thing to my 80 with an old fan from a 4Runner. It’s perfect for stop and go traffic, slow speeds and on the trails. World of difference in the AC temps. Great mod!

[@motor.mausGarage]

Absolutely! Good idea as well!

[@Ghostrider-71]

Great video, very informative. My AC feels a bit humid so I think a new dryer is in order. This fan set up looks like it would make a difference. I might have to try it. Thank you for posting.

[@motor.mausGarage]

This has been one of the best mods I've done hands down, really makes a difference at idle for AC.

[@Ghostrider-71]

@@motor.mausGarage I will have to try it.

[@NigelNaughton]

It's always good to torque down the grill screws to 300 ft/lbs 😜 So whenever the AC is on the fan will turn on? It doesn't gauge what the temp or pressure is in the AC system is and then turn on? I think there are a couple of write-ups in Mud about this. I am curious to see what affect this has on the H2O temps when that air is being blown over the radiator.

[@motor.mausGarage]

Yeah, basically this fan runs off of the AC pressure switch, I'm not sure what the function of that switch is, perhaps for compressor operation. I went wheeling soon after this and it keeps the temps right at 190 while doing low speed stuff and idling. It was about 85-90F ambient temp so I think that's pretty good. We'll see this summer when we're well over 100 degrees lol

[@kptheprelander]

So now that summer has definitely hit, how is the fan working out? What kind of temps are you pushing? In Vegas around 110°+ I'm pushing 60°ish without a fan

[@motor.mausGarage]

Yeah I'm sitting around 102-108 depending on the day. I haven't measured it directly, and admittedly I should probably replace my condenser, but so far it has made a pretty significant difference over not having one last summer. AC is quite nice when idling for long periods compared to basically non existent before 😂.

[@fromwatertowater]

What is that beefy radiator you have in there?

[@motor.mausGarage]

That is a Ron Davis radiator OEM replacement. 10/10 recommend, well worth the money.

[@TOPOM42]

Those solder joint connectors are trash. Bought some and just metal plastic before the solder melts, heat gun isn't any better

[@motor.mausGarage]

Good to know, figured I would use them on something less critical just in case 😂

[@Dimitron20]

why not just upgrade the clutch on the belt driven fan to move more air???

[@motor.mausGarage]

Already did! This is for idle/low rpm AC performance mainly

[@Dimitron20]

Oh, perfect! Do you have a link to it by chance? I wanna see if it'll be compatible with my 80. Mines got the diesel engine, and i dont have the room to install an Aux fan because of all my coolers i added an intercooler.....

[@motor.mausGarage]

This is the one I got, but I don't think it'll work with the diesel engines. I'm not sure if there's an equivalent 🤔 redlinelandcruisers.com/shop/80series/1fz-fe-80-series-land-cruiser/modified-95-degrees-fan-clutch/

[@Dimitron20]

Thank you! I sent them a email asking about it. 🤙
