Not sure if I have seen one? The specs as rockauto lists them; https://www.rockauto.com/en/moreinfo.php?pk=3608253&cc=1276691&jsn=402 Not sure I believe the 1 core and/or 1 1/4" thing? the ones that have performed the best have been 1 7/16" and 2 core. If it is that thick of a single core, could perform well?

I guess its one of the NAPA house brands. Seems like a low tier option. I am trying to talk to CSF about a replacement but they wont even talk to me. Im guessing because I installed it myself they wont bother. paid way too much to get a faulty rad AND no customer support.

100% correct, this is also where is the 'sweet spot' for cruising snd fuel vonsumptiin

I was 'saying', there is a speed versus airflow point where the airflow keeps the engine cool however, go past that and the engine starts to heat up, so the viscous coupling starts to drive the fan, at this point you are using additional power/fuel, how much YMMV?
The link in my sig has all the info, suffice to say I am a tad OCD about this stuff.

You are aware that diesel/manual setup differs from gasoline/auto ones right? Depending on conditions, etc, there are likely narrow windows where it will self cool, but outside of that not so much. It's safer to say, that for practical purposes, the 1FZ/auto (the subject of this thread) is fan dependent. Diesel research is awesome for that platform, but is useless for a USA spec 1FZ.
On ebay there are a variety of huge aluminum 80 series radiators available for pretty cheap. Might want to consider that instead of a wimpy plastic one or failure prone CSF.

Link to the proper one for a USA spec, proper sized hose, trans cooler, steam port, etc, have looked and not found one?
Yeah, yeah... I'm sure there's something you could nit pick with any of them. I didn't buy one for a 1Z myself (I bought a manual diesel radiator from GPI and it is a beast) but there are tons of different ones if you just search for fj80 or fzj80 radiator.

That one looks like a winner to me - with an external trans cooler of course. I don't buy the needing the trans cooler within the radiator line of thinking myself.

I have tested plenty of different setups over the years both petrol and diesel although the majority have been petrol engines, but no testing on a petrol 80. The results have always been the same, more stock and tuned four cylinder engines than you could wave a stick at, as far back as a stock and then tuned 3 litre Capri in the 70's, V8 Capri, V12 Jaguar ect ect. No fan has been needed over around 30 MPH thru to around 70 MPH.
Even assuming all engines are in perfect tune (petrol not running lean or diesel running rich) the results will be the same, agreed there are many variables, workload, space around engine, frontal area, but why would a USA spec motor be any different?

Because it has a crapload of smog restrictions on it.

Yep in Europe we blame the Americans for that.
Seriously though, we have not escaped from smog pumps and EGR rubbish, but how much impact that adds to the cooling system is unkown?
I do know that engine bays are more crammed these days with smog gear and particle filters, and yet the electric fans are rarely called on except for AC use.
Perhaps the USA spec is different with ROTW?

I think this is the crux of why your points are being challenged.

Absolutely agree, very possible the petrol 80 is a special case, so even more important for people to keep an open mind, and explore different avenues and ideas involving topics of this nature.
