Get too low and I think it’ll run all the time
Exactly, and I don’t trust the fan or switch to last if I go with a 140* switch bc it would be on all the time. 160* might even be a problem.
I need to find out the duty cycle of the fan.

Am I the only person running this kit with the thermostat pointing down at the ground? I double checked tightness.
I had mine turned on for hours on a recent trip out west.I need to find out the duty cycle of the fan.
Amazing. Thank you.
Now I need to find out if 1/8 will work. I read somewhere that the Derale is 5/32. Can’t find that info again though so I’ll need to confirm things.
Per Derale, the switch is 6/32, it screws into the 1/8 npt plug.
Worse case, if the amazon switch isn't 6/32, you would have to switch to their 1/8 npt plug.
Nevermind, that's not right.
So worst case maybe I could run an -6AN coupler and drill/tap in the correct diameter & thread for the thermostat switch.
Edit:Or plug off the little port in the current coupler/housing and tap into that to install the other thermostat switch.
It would be nice if Derale simply has other compatible options.
I'm thinking (hoping) they're all the same size.
I'm going to try a 170° off of Ebay.

Pretty much all day, for 2 weeks.
What were your peak temps on the gauge during that time?
I wish mine worked that well.
I've never seen the temperature go down because of the fan.
Normally it stays at 180°, but air temperature and hills affect it the most.
I've even seen mine go to 215°-220° with the fan on.
This is usually on highway inclines, not crawling.
I am not claiming that if I install the 140F switch it will always stay in that area. The fan will kick in earlier and it will run cooler on average.
As for going to 220F - is your radiator OK? The oil is supposed to be cooled by radiator as well, and there it is liquid to liquid cooler. Assuming that your cooling system works fine, 220F seems to be too high. Did you disconnect the radiator cooler?
It's 2023, time to realize this cooler isn't what it's made out to be. Look into the setrab that Blaine recommends. No extra fans or wiring, no bad mounting locations.

Main thing that I like about this Derale cooler that it is located far away from engine bay and it does not add to the heat load of the radiator. I don't think that the location is problematic.
Have you considered that the Derale might heat load the radiator since it doesn’t cool the fluid as well as the Setrab?
Regarding air flow, the Setrab doesn’t harm my engine cooling. And that’s with a PSC cooler above it and the Derale sending hotter fluid through the bottom of the radiator.
Blaine wouldn’t install the Setrab if it compromised folk’s engine cooling systems.
I am not saying that Setrab is a bad solution. It is cheap and it works.
I do think that Derale cooler with lower activation point, like 140, will do it’s job as well.
I don’t believe the Derale fan coming on sooner will cool the transmission fluid as well as the Setrab does, but I hope the results are good enough to allow me to keep running it without damaging the transmission.
