David Brown Case 1210 running hot

kmdugger · Apr 16, 2020

We have a David Brown Case 1210 4wd that is showing hot. It s goes from cold almost directly to hot. The top hose at the thermostat is warm but the other two hoses are still cold. The top of radiator is warm but the bottom is cold. Do I need to check anything or be concerned? It seems to be running fine. I have not ran the engine long after this happened. When this first happened I had been mowing all day and it just suddenly showed hot. I do not remember checking the hoses that day. Maybe a bad gauge?

Sounds like the gauge or sending unit took a dump, if it isn't air locked. Could be an air lock if radiator was low & fluid added when she wasn't running & circulating.

Bottom of radiator should be cooler that the top, means its working. I agree that you gauge may be shot. If you are concerned check it with an infrared thermometer or a candy thermometer

Plugged up radiator core would act like that.

If the gauge is all the way to hot, and nothing bad is happening, like blowing steam, loosing coolant, smelling hot, then I would suspect the gauge.

If it's an electric gauge, could be the sending unit, or the wire is shorting to ground. When the gauge is showing hot, unplug the wire from the sending unit, it should drop to cold. If it stays up, look the wire over for damage, pinched, burned, mouse chewed.

If it's a mechanical gauge, unlikely it is giving a false high.

When the engine is up to temperature, you should feel hot air coming through the radiator. If the air is cold, there is no circulation. Could be low coolant, failed thermostat, clogged radiator, rare cases a failed pump impeller.

The gauge is electric so maybe it really is just a bad gauge. I ll try unplugging like you said and see what happens. The fuel gauge also always shows empty, fortunately it is easy to look in the tank to see the level.
