Automatic Trans Radiator for FJ40/45/55

[CaptainAussum]

Hello everybody,

I’m pretty new to Mud but have been reading lots of threads and builds here for a long time.

I’ve been working on my FJ40 for a while now, and have decided to swap the drivetrain to the 1KZ-TE / A343F. This is coming along pretty good, but recently I was wondering about radiator options for this application. I found a company on eBay that builds radiators for both the 1KZ-TE and FJ40 but I wanted a custom rad that would work for my situation. So I contacted them with a request and some design sketches and they said they could do it.

These are my designs...

I’ll be ordering mine from them but I’m wondering if there is anybody out there that might be interested in something like this? The radiator is based off my original 1969 Toyo, so all the mounting tabs, core size, and overall size will be the same. Where it differs is obviously the bottom tank and trans cooling line, but also the OD of the inlets and outlets are 38mm instead of the 36mm measured on the original.

The cost right now is ~ $360 US, delivered. That might go down the more that gets ordered. I’m told lead-time could be a couple months but I’ll find out for sure when I order mine.


Some links to look at…

Thanks for looking! If you want, I can email you the SketchUp file with all the measurements.

Probably should have mentioned that it'll be constructed entirely out aluminium and 100% TIG welded.
The core thickness will be either 62mm / 56mm / or 52mm still waiting on confirmation on that. They're unable to produce the 70mm thick core that the rig originally came with.

Also, here's the manufacture blue prints...

Few notes.... I would be interested except the thinner radiator would be a bit concerning on a V8 conversion like mine (I have a feeling I could struggle to keep up as it is).

Is opposite end auto-trans inlet/outlets the best option for most vehicles? As in - won't the in/out lines be on the same side of the vehicle and possibly be best on the same side of the radiator?

This could also be used for those with a MT who have upgraded to a Saginaw and want a PS cooler

Sorry to leave anybody hanging...

Thanks Carreta, I think I'll be going this route and scraping this project, I got confirmation back from Worley on the core size. It would be a 3 row, 52mm (~2") thick core with 14.5mm (0.57") tubes so roughly the same as the mid level Champion radiator Carreta pointed out above. My goal was to get a thicker rad made than the champion, but if they're gonna end up near identical not really worth the extra cash/time/effort.

Toyotaspeed, I would look into the Champion radiators. The one I was referring to above is suppose to be able to handle 500hp, if that won't work they sell one good for 600hp. As far as the design of my rad, all I did was copy and merge the stock FJ40 and Hilux radiators the best I could. I was hoping that Toyota R&D wouldn't let me down.

I'm going to get back to working on the 40 now..

Well.... what I've been reading is that HP rating isn't really everything when a SBC is thrown into a 40.... it sounds like placement of the engine and type of fan have almost just as much ability to cause the engine to overheat due to engine bay ventilation (and I have seen this first hand with a friends 68 350 swapped).... so taking a radiator that is barely keeping up and then putting one in that's smaller (potentially less capable to dissipate heat) then you could have issues.

That's all I was getting at.

And also that an AT cooler could be used as a PS cooler for those with manuals

Given that it appeared my factory radiator had a leak and the core was too thick to accommodate the oversize coolers I purchased for trans/oil... I ordered the champion radiator.

My FJ40 has a V8 that's got a very forward mount in the frame... it has a flex-a-lite fan mounted without a clutch and it fits with the stock radiator (and yes, I have run it like this). The champion radiator has the trans cooler that juts out past the core about 1/2-3/4" (over stock, the lower tank is flush with the core) and as such, at least with my current setup... doesn't fit. The fan makes contact with the cooler tank fitting.

They did offer to return the radiator and indicated they have never heard of this problem - they recommended I make sure I can't "make it fit" but then said if I modify it to try to get it to fit then it isn't returnable.

Fun times...
