Hi Everyone,

When I bought my H, it had the temp gauge there but the wire connecting it was gone, and the old bolt still in the block. So i finally got the new gauge, and got the old bolt out of the block, and installed the new guage, and it does nothing, just stays on cold, So i asked my dad about it and he said he thinks there should be some form of electricity present to power the gauge from the temp sending unit....Any ideas? Am i missing something?

I have found if you have added an external tank heater and "T"ed in off the cylinder head the temperate gage will not read at all.. So I plumbed it back int the block and it was good then...

I thought the temp guage on my 350 wasn't working, hadn't moved off the cold peg for three years. Last summer I hooked it up to a 7' foot bush hog and started cleaning up some CRP, after an hour the needle was sitting in the middle of the guage, after two hours I started to get carbon flakes blowing out the exhaust. I was luicky it didn't start the field on fire.

Water boils at 212 degrees F. Or a bit less if you are above sea level.
Put the end of the temp probe in a pan of boiling water & watch what happens.
Those tractors usually were hard to get hot enough to vaporize the tractor fuel (distillate) so many had shutters on them to manually control the air flow thus allowing the engine to run hot enough.
You should still get the engine up to 180-200 degree range to get maximum power & efficiency out of it. The oil will finally get hot enough to "boil" the water out that causes sludge.

I bought a new temp guage from CaseIH this spring and it does not work. The needle hangs clear to the left and after working the tractor, it finall touched the green paint(run). I'm taking it back.

Just put a cooking therm in the rad when you have it running those guages have to get pretty warm to register. You can always check it out by removing the bulb and lighting a match will move the guage. Better yet remove bulb put it in a small metal container of water with a thermometer and using a propane torch you can test the guage and therm at the same time.

No electricity involved. It will take a long time for the guage to come up if the tractor is only idling. You need to work it to get warmed up.

where did you get the new gauge just because its new doesn"t mean its a good one.On the H the temp gauge is a thermally operated gauge meaning it require no electrity it works like a therma couple in a gas furnace heat causes the probe to make an electrical charge that moves the gauge up and down.I would heat some water to a boil and drop the probe end of the gauge in a check to see if the gauge will operate that way. I suspect its a bad gauge I have had the same experience a couple of times Hopes this helps RIVER BOTTOM FARMER

Those old gauge types don't use electric. They work off of heat transfer thru the core of the braided transfer cable. The gauge could be stuck/defective. If you pull the sending unit back out and pass a propane torch or lighter back and forth across it, you should see the gauge rise.

Actually, the mechanical gauges operate because the vapor pressure of a "working fluid" (more or less FREON) in the gauge bulb is linked to the heat gauge (actually a pressure guage) by the copper "capillary tube" connection the copper bulb to the gauge.

And if there is no thermostat installed and the tractor is not worked hard, it may barely come up off "cold".
