universal inline (in hose) thermostat???

Is there such a thing available that anyone knows of??? I need a thermostat for my tractor but they are hard to find used and still good. Really don't want to pay the price (almost 300 bucks) for a new one. They are sealed units so rebuild isn't an option with my level of expertise. Rumer has it that there is an aftermarket that you can screw apart and replace a couple buck normal thermostat but I haven't found it.
Any tips? This is what they look like. Not sure if the bypas is really that important?

Thanks for any tips.

The bypass is necessary to keep a little coolant circulating through
the engine while the thermostat is closed. You could keep that
intact by leaving a gutted stock thermostat housing in place.

For a thermostat, some of the older Minniapolis Moline tractors and
pre 1949 Ford V8 cars and trucks used a thermostat cartridge that
fit inside the upper radiator hose and was retained in place by a
hose clamp outside the hose
 
(quoted from post at 14:35:14 02/06/11) 9/2/8 Ns also have the thermostat inside the upper rad hose.

Any idea the diameter? Just cut the hose and clamp it in? Is 160 degrees enough temp for a diesel motor?

Thanks, Dave
 
in early 70's I worked parts counter at car and Jeep dealer with French cars- Renault and Puegeot- that had thermostats in upper hose. The aftermarket parts house also had some of these thermostats. Were about $8.00 at the time most Chevy and Fords were $5.00, small bypass hole. Model T club people got a couple to use in their projects, some of antique tractor people also got them as cheaper than 'must be ordered custom at the time thermosiphon' system thermostats and were off shelf. Might want to check the foreign car parts house for somthing that would work, the Peugeot was about a 2 inch diameter. RN
 
To install the Ford or Moline thermostats, you do not cut the hose.
You slide the thermostat up inside the hose, far enough to not
interfere with the pipe nipple on your old thermostat unit and
retain it in place with a radiator hose .clamp outside the hose.
 
Should bee least 185* or 190* diesels like it hot, what I did one time was to bolt two 79 chevy thermostat houseing together then put the whole shebang in the hose.
 
Rusted Nuts gets the prize for a great idea made from junkyard parts. :)

Two thermostat housings, a thermostat with a tiny coolant bleed hole drilled in it, a gasket and two 3/8 bolt /nut. Makes a great inline thermostat housing from easily availible parts.

Great tip, thank you. :)
 

the bleed hole to take the place of the bypass? I'll be at the junkyard when it opens up on Tuesday.

Your welcome, I was in the same boat as Dave 2, only I was in the USA and needed a thermostat for a German diesel, small world.
 
You may still need the bypass, the houseing I use had a pipe plug in them removed it and put in a 1/2 nipple to hook on the bypass hose.
 
You just have to make sure the thermostat is in the right direction. I had a mower with a Continental R (Renault)engine that had the thermostat in the hose. You want at least a 180 in a diesel and a 190 doesn't hurt. Dave
 
Dave something to reflect on. I would cut the old housing apart, braze /mig weld a flat circle (cut from sheet steel -thin) drill new bolt holes around the flange, make a gasket, install a new thermostat bolt both halves back together,that way by pass is still functional. Just a thought. VICTOR.

Thanks, but that's just a tad beyond my capabilities. Got one more place to check and gonna try rusted nuts' idea.

Thanks though,

The German IH tractors used this thermostat. They are available in Germany at 135 Euro which is rather pricey. The side fitting is for the temperature probe. The first thermostats did not have the temperature probe fitting as the temperature sensor went to the bottom tank of the radiator. When they shifted the temperature probe I do not know. The unit in my D-214 has the thermostat wide open (cold) and was in the tractor upside-down. The by=pass is a small hole in the thermostat which is clamped by the two halves as the centre joint. If I thought I could un-roll the joint I would replace the thermostat unit and re-use the two half tanks.

If I could find it for 135 euro, I might consider it. Think I'll just do the idea rusted nuts had. How does your D214 perform running cold? Do you have faom in the oil filler tube and does it slobber gunk out of the breather tube?

It seems you could could solder one up from copper pipe fittings. Of course by the time you bought all the parts you would be close the cost of the original.

And yes, you do need the bypass. Otherwise the thermostat won't open when it should. And you'll get hot spots in the engine.
 
O n Ford cars the in hose thermostat was used 32 to 36.Ford stopped the outside clamp because it was over tightened, that meessd up the thermostat.In 1937 to 48 the thermostat sat on top of the water outlet and was held in place by a necked down water hose.The bypass lets the heater work sooner.My 38 Dodge had a bypass hose.New cars have a bypass for the same reason.
