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!
If you want really cold AC either fit a new evaporator core with a new TX valve or get your existing evaporator core cleaned thoroughly which requires removal. If you try cleaning it without removal will not be as good but ideally just get a new one. You would be surprised how much crap blocks up the evaporator core over the years limiting airflow across it. I got mine replaced with a new one made a huge difference much colder and stronger air flow. I also run a condenser fan.
I have cleaned mine out in a video that I had never posted as it didn't come out well and I didn't film very much 😂. I didn't replace it due to them not being available in the US, but I didn't know about partsouq at the time, so I may revisit that when I replace my condenser at some point in the future. Also threw a new expansion valve and dryer in as well.
Toyota really cooked the 80 series with the small condenser. I have a surf where they slung the condenser under the engine and its awesome. With the additon of that extra fan on your 80 series I would also charge the ac and go over to give it more subcooling and to stack more liquid refrigerant in the condenser. Another more expensive route is to replace the condenser with a new direct fit or a much better universal fit micro channel. Your car already has the largest denso compressor offered so replacing that will be fruitless. Another thing you can do is replace the evaporator and TX valve. Toyota at least used off the shelf denso parts so its relatively painless to source. I am lucky with my Hilux surf as toyota slung the condenser under the engine. I removed the twin 7in thermo fans and fit a 14in SPAL fan. replaced the evap and TXV and it really gave it a kick up the ass.
Great tips. I did a lot of AC work before this just to refresh it, but there's still the original condenser on there. I have a new one from Toyota but you bring up a good point on the size of it, I may look for a larger one 🤔
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.
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.
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
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
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 😂.
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.....
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/

Absolutely! Good idea as well!

This has been one of the best mods I've done hands down, really makes a difference at idle for AC.
@@motor.mausGarage I will have to try it.
Hey love your videos , what size is the aux fan going to do the same on my 80 series.
This is the one I used, I think a 12 inch would be the max you could fit imo.

What is that beefy radiator you have in there?
That is a Ron Davis radiator OEM replacement. 10/10 recommend, well worth the money.
why not just upgrade the clutch on the belt driven fan to move more air???
Already did! This is for idle/low rpm AC performance mainly

Thank you! I sent them a email asking about it. 🤙
Those solder joint connectors are trash. Bought some and just metal plastic before the solder melts, heat gun isn't any better
Good to know, figured I would use them on something less critical just in case 😂
