Perhaps the tractor was designed for shutters only?

Good normal temp is between 180 and 190 Degrees F. Get a 180 thermostat from a decent auto parts store for a 1980 International Scout. Works and fits perfectly. It has the big diameter plate. No adapters needed. Make your own gasket.

It looks like your tractor never had a thermostat. Get a thermostat that goes in the radiator hose like the one above. This one is for a Ford 8N. It is for a 1 1/2" radiator hose. Measure your Rad hose to be sure it will fit. Make sure it is a 180 not a 160 Degree unit.

I've done the same thing to my C and one of the WD45's.  Some of the new radiators line up, but most don't.  I use 2 thickness of the inner tube and it's been great so far,,,,,5 or 6 years now.

My upper hose is 1.25" inside diameter. I bet I can find one to fit, but making it "stick" in one place is what bothers me. I don't want it shifting and losing seal, and maybe blocking water flow. I may just see if I can find a set of shutters.

theropod, your '38 'B' never had a thermostat. That is the early style water manifold as they called it and those types never had a thermostat. They used shutters to control water temp. I have an early '39 'B' which has the same water manifold.
 After engine number 23815 a thermostat housing was fitted which is the type that has the spring  to hold the thermostat in place.

well, Phil identified theropod's housing and satisfied my curiosity. thanks!

here's a picture of my 1941 housing trying to give ranse an indication of how thick the original "bottom plate" was.
mine looks to be just a hair under 1/8" and is presumed to be factory.

3 Ford 8N's I loan to neighbors, but the '52CA, '41B and little B1 I do not.

Thanks Phil. That eases my mind.

Since I don’t have the shutters anymore, or anywhere to mount a temperature gauge, I am sort of up against it here. Even if I had the shutters there would be no way to know how hot/cool the engine is. My radiator is internally vented so my B was never meant to be pressurized. Those caps with a built in gauge have short little probes, and if the coolant evaporated it would quit working right.

I am tempted to drill out my tower/manifold thing and tap it for a sending unit and mount a gauge on the tool box where the crank handle stores. I bought a straight shank crank to replace my old one as it is absolutely wore out and it won’t fit on the mount point. That would be a perfect place for one.

This all sounds like a spring project, so time isn’t a problem.

Yesterday's Tractors has a sensor & gauge kit for $22.
listed in ford 8n parts, but says universal.  numeric gauge to 250, metal wrapped capillary line, 2" gauge.
I bought 2.
they also have a hose adapter which I passed on - I'm gonna drill and tap a designated boss on the head (which surprised me!) on two 8N's.
worrier type here - can't imagine running a water cooled engine without a visual check on the temp here in too-often-hot SoCal.

I'm glad someone identified theropod's housing.

drobCA, thanks for your pics. I guess mine was correct after all. I need to order a spring and I think I can reuse the home made plate. Someone did kind of a crude job but it didn't leak so it should be ok. I can't imagine why someone cut a square hole in your hood. My sheet metal isn't perfectly straight anymore. If you look closely you can see the gauge is not dead center in the hole. This the only reason I can think of for making the hole larger.

the magic words are "it didn't leak", Ranse.
so likely it will work again.
I just wanted to let you see what "normal" looked like so you could come to your own conclusions.
I doubt even the correct police with magnifying glasses would notice unless you pointed it out.
meanwhile it's pretty and it runs.
enjoy your B!

I have a set of shutters for WC, WD, WD-45 if you're interested.

Hey Phil,

I assume you are addressing me. If not disregard the following, or not. :-)

I am not too worried about this cooling issue right now. It has finally turned into winter here in the Ozarks, and most of the work on the B is now on hold until warm weather comes back. I just don’t do cold anymore without absolute need, or if I am hunting, which is.

Aside from refilling the cooling system, and starting it a few times between now and spring, not much work is planned, with cooling system draining after each running session. Yanking the lower radiator hose off, and pulling the plug on the side of the block gets it dry, as the tractor rests slightly favoring that way and is no biggie. I still need to set the valve clearance with the engine warmed up, so I HAVE to get that done. Media blasting, and immediate repriming, appointment for the drive train in mid January is the next big step. A new manifold is going to be bought and ceramic coated at a commercial shop. I still have time to think about the color and finish for the drive train, but I am still leaning toward a flat black, or maybe a satinish less-than-glossy black. All the sheet metal, steering system and wheels will be in the shade of orange I have choosen. New wheels and tires..

I am going to start looking at the transmission and final drives for the same thing the engine experienced (condensation of epic scale). I may need to flush those systems and drive the axels, and slip the brakes to knock off crud, and flush it all again. I have the tractor on jack stands/huge blocks of wood, and should be safe to run in gear(s).

How much would you need to get for the shutters? Maybe you need a part from my donor B and we could make a trade? It has workable fenders with the left being really nice. Block is shot freeze busted bad. Tranny seems to work. No pto. All castings except block sound. I’m almost tempted to fix it too.

WC,WD shutters wont fit a 'B' radiator as they are too wide.  I have both types here.

Not to threadjack, but did Bs always come with shutters?  I have a later one (1951) and it does not have shutters and I was wondering if it should.

I think if there is a hole on the magneto side of the radiator shroud near the top of the cover your tractor was equipped with them, or that sheet metal part was built for a tractor that did.
