In NYC driving(lots of parallel parking and low speed turning) I have found the fluid will turn dark very quickly. I think it could definitely benefit from a cooler if you go up in tire size and load rating.

I need to investigate. Granted valid point. The fluid would go to coolant temp.
I can remember my 87 5 speed xtra cab pickup had power steering an it actually has a loop cooler on it out by the front radiator for the power steering cooler but that was on a 22R engine 4 cylinder and a decade prior.

1/3 of my AC condenser on my grand Cherokee was for the PS cooler. On the V8’s the cooling fan was powered by it.

Coolant temp at the bottom of the radiator is much cooler than engine temp (unless you switch to e-fans with a high-ish turn on temp, maybe). Check the lower tank temp sometime... It would work well as a cooler - and might overcool in harsh winter conditions.
A small cooler for the power steering system is reasonable to install and might be a good idea for those that work the PS system hard (big tires + hard offroading). You might even be able to run something down on the frame rail to keep hose routing from causing a hassle higher up in the bay.

couple of things.
while not a full flush, I did change out a lot of fluid now, nearly a quart to full synthetic, and this morning, at -27 it did not seem so stiff after warming up.
soon I will do a real flush, and flush and fill the tranny to full synthetic. ( and a new radiator)
p/s heater and cooler. While I dont see a need for a cooler, but is a good point about those that rock crawl and really push their powersteering. Many years back in pennsylvania, for towing a trailer to claifornia, I geared my sons honda pilot up to towing. It was recomended by honda that it have a p/s cooler for towing and a big after market trans cooler, . So I put on a big auto trans cooler and then used the loop cooler that ran in front of the radiator originally for the trans and made that into a p/s cooler. I thought that was cleaver idea, so when I lived in the lower 48 picked up one of those loop coolers at the wrecking yard to install in my 4runner, thinking it would keep it cooler, add some more capacity and hook a magnafine to it, but never put it on. Anyway.......
But for those that might be concerned with the p/s getting too hot, , one of those loop coolers might be a good option.

You are correct. I had that all messed up.:shrug:
No wonder everyone is saying what in the world. That's my fault..
Doing too many things at once again.
Thanks Guys for the correction. The concept was to heat the fluid in our case you fellows are correct. I do notice that the temp gauge has to be at a certain Point to shift into higher gears auto transmission is still cold.
Did anyone ever look into the Tundra external coolers that are on the ones with the towing packages rigs? Those could be used as external coolers for those who bypass the internal transmission cooler.
I was at a pick a part and all the tocumas and tundras that were there had those on them. Looked like it could be very easy to work for the 3rd gens.
Has some size to them. Might even be a larger diameter line. I didnt look that closely.
I also know that I since we cant get 5 speed manual radiators, I will hook up the trans cooler for my power steering making a cooler and heater... What the heck its going to be there so might as well hook it to something. ;-)
So I will have a power steering cooler and heater by using the internal transmission cooler for the power steering.
on the tranny, dont those tundra ( and maybe sequoia) also have a thermostat for the coolers with a loop back if too cool. Thought that was a good idea. I know a lot of the aftermarket coolers state that they have a built in bimetalic valve to limit the amount of fluid going through cooler if cold.
Also now with synthetic fluid now in my p/s it was not as stiff today at -27.
