Remote oil thermostat install ?'s.

[Lou]

As part of my effort to ensure max cooling for my Scout I installed a hayden plate type auxiliary trans cooler in series with and downstream from my radiator cooler. It works great in the summer pulling a trailer but I’ve found that in the winter months the fluid is overcooled. It rarely rises above 100 deg. I’m now looking at installing a derale remote oil thermostat to put the lower temperature reading in the 170-180 deg range. Being quite capable of over thinking anything I’ve determined that I have two options in plumbing the thermostat into the cooling system. What I don’t know is if it makes any difference other than one way is a simpler install.
First routing option: the pressurized fluid leaves the trans and then enters the radiator cooler, then to the remote thermostat which determines if the fluid is sent back to the trans or on to the auxiliary cooler and then return to the thermostat.
Second routing option: the pressurized fluid leaves the trans and goes straight to the remote oil thermostat. From there it’s either returned to the trans or it’s sent to the radiator cooler and auxiliary cooler circuit and a return to the thermostat.
I’ve thought of several pros and cons for either method and can’t convince myself that one is better than the other. If there is no genuine benefit of one over the other then I’ll go for the simpler install. That would be the first option.
Has anyone installed a remote thermostat and what have you seen as a result?
Thanks,

Shit man, see what happens when ya ain't gotta j.o.b. To go to? Ya spend all day in yore skivvies look for more shit to dream up. Yawl need to be workin' on a plan to git tha hail outta kalifornikate before it's too late, don't forgit, we can make that riverfront next door to us "available" for ya!

But since all you are good for now is surfin' shit all day, take a look at earl's stuff and home in on the "tech" in the azzend of the catalog:

earl's performance plumbing, hoses, hose ends, and brake systems

That is the tstat I'd use from now on.

And...in your case, I'd not run the tranny through the radiator, use the tstat (with built-in bypass) in stand-alone mode with the tranny cooler.

And yore next question is..."which tranny fitting is the out and which one is the in?". The $1 answer is...the front port on the tranny is the out that would go to the in on the tstat, you figgr out the rest!

If we wuz neighbors, we could be doin' this shit in our skivvies every day,I got plenty transmission cores in the shed you could practice on!

Hola Mike, thanks for the contact from the outside world. The wife goes to work and I drink coffee all day and look for crap to bolt onto the Scout. I have in hand a derale thermostat #25011. It’s to begin to open at 160 and be fully open at 180. Your response tells me that my first option works best for me. It won’t hurt anything to go through the radiator first (might even help warm the atf quicker?) and it’s much easier to plumb. The auxiliary cooler beyond should take care of any remaining cooling needed to keep the 180 max. I’ll just keep an eye on the temp gauge and see what I get. I can always dump the derale for the earls and replumb the whole mess.
I’m staying in calif for now, I wanna see how this ends! With any luck gubna brown won’t be raising the skivvie tax for awhile. Meanwhile I’m now stuck with this damn caffeine enhanced image of the two of us doin’ shit with tools in our skivvies. I can think of two women that are gonna sit in the kitchen window drinking wine and making crude and rude comments. Sounds worth it!!

It's gonna end dude, with the moonbeam finally bein' transported back to wherever the hail he was hatched at on that asteroid in some other galaxy.

Let's see...he fooked up kalifornikate once already, he fooked up oakland but it's no worse off than before he fooked it up by maintaining status quo, no yawl gonna let him keep fookin'.

In the meantime, that derale stat system will work just fine, I'd leave the radiator out of the loop though, that why we're puttin' the standalone stat in the loop.

Ya wanna "warm" the tranny? As soon as the autochoke pulls off the first high idle cam, then powerbrake the tranny with it in d or r for 10 seconds at 1/2 throttle. Make shore the camaro ain't parked in front or behind though! Powerbrakin' will heat a slushbox much quicker thana microwave oven! If ya have a tranny temp gauge installed, ya can watch the needle move while powerbrakin' like the second hand onna clock (analog clock though!).

Muchas gracias Mike, standalone cooler it is!
We’re on a suicide watch down here. The smartazz liberal I used to work with years ago asked me how I planned to deal with y2k. I told him I had five days worth of food, five days worth of water, 15,000 rounds of ammo and his address. He figgered I was all good.
And now we’ve not only got moonbeam back, we’ve got kamala harris as attorney general. I’m gonna need another auxiliary cooler and thermostat that I can stick in my butt!! We need you as governor down here Mike. Just make sure you don’t have any illegal nanny/cleaning ladies in yore past.
Thanks again to you and IH only for sponsoring this excellent website and tech service. I'll post up some photos when I finish cobbing this thing together.

Ok, it took a couple of weeks but I have the remote thermostat installed. I welded up a bracket to mount the thermostat to the radiator support. I plumbed it into the existing hard lines and should I ever need to reconnect to the radiator cooler circuit it's a ten minute job. As it is I'm only using the hayden cooler (#679) behind the grill. As the derale thermostat (#13011) approaches 180deg the valve begins to close, sending the fluid to the hayden cooler. I drove it on the freeway today at 55deg ambient and the trans temp sat at 155deg. What I've read indicates that the valve is open, with minimal flow to the cooler until about 160deg. At that point it begins to close, being fully closed at 180deg. I'm curious to see what it reads this July when it's 108deg ambient and I'm pulling my trailer.
I'm also now a believer that you can overcool a transmission or engine or anything else that is engineered to operate with hydraulic fluid in a defined temp range. If I can keep this between 160 deg and 185deg I'm happy. Prior to installing this thermostat the temp wouldn't top 90deg on a cold day.
Thanks for your help Mike!!

Nice work man!

Should now be about time to do the motor though so's yawl can make it up to the bee in July? Yawl must come stay for a few days either pre- or post-bee. Pre-bee is best looking forward now, we won't have anything on the books this coming year, just the bee!

Hey Mike, I checked with anna and we look good to do a pre bee stay. I'll load some roundup in the crankcase so that when the truck leaks at least you'll get some weeds killed.
