Temperature light stuck on a F20D

[pcrllo]

Have an F20D with aTemp light that comes on the moment I turn on the key and remains on till I shut it off. Wanted to try to figure out what the problem is but I'm at a loss as how to access the instrument cluster. there are two screws on top that I thought would be the key, but no luck initally and I didn't want to force again and cause more problems. Can post more picutres of the dash area if necessary. Also what might the problem be as far as the light is concerned?

Maybe I missed something but why do you want to take the dashboard out? The light seems to be working so it's not from there?

Anyway, to me, that symbol indicates coolant level and so does the text under the symbol after translating it. Have you checked the level of the coolant at both the radiator and expansion tank?

The coolant temperature gauge is on the right side, under the fuel level.

The TEMP light translated says radiator running hot.

Do not take the dash apart.
Instead, check to see if the tractor has enough coolant, the radiator is not plugged up, and the water pump is working.

The radiator is full, expansion tank empty; and water moves normally through radiator when observed with the cap off while running. Several reasons I wanted to look inside the dash; the light use to come on when I turned the key and go out after the engine started, also have a second wire I'd like to trace from their start in the dash. Finally the throttle lever has gotten very stiff from our PNW winter rains and I'd like to see what might need to be lubercated there.

The water level sensor is installed on the expansion tank. It's empty, the light will turn on, so it's working as intended.

When I translated it to Portuguese, it translated to "radiator water amount" and the arrow does indicate level.

Thank you I hadn't noticed any sensor on the expansion tank; I will look for one and a water level mark.

Just FYI, it is a good idea to have some coolant in the expansion tank; it helps keep air out of the system.

All the best, Peter

I used google image to text. I wonder if the other two image-to-text translators would do a better job.

I would agree with your findings. Even the image shows fluid level.
Maybe it does both ? It is a temp light.

I wish there were more manuals to be had for the F/FX Series.
Yanmar did additional amazing product innovation with these machines over the YM series.
When the AF and EF series arrived, the tractors reached a more modern level of functionality.
The downside is, those electronic PCB controllers and sensors on these machines are nearly impossible to find replacements. If I had to find something equal to my YM2610, the AF326 would align.

In the early FX series, the YM engine 3TN84 is used in the popular FX24. And likewise the 3TN82 in the FX20. Both are considered good working machines and common parts to find.

Not sure how it differs, mine reads 3TNB82-U

Long shot here....have check radiator see if clean also air filter.

Light went off the moment I started it with the expansion tank filled to the full mark. Thank you, I've never used the image-to-text translators spoken of here, I have to check them out.

Oh it's very handy, specially for stuff like this. Most of these grey market tractors were never meant to be sold outside the Asian market, so they really never released manuals in English or any info really.

I'm sure there are others but you can install Google Translator on your phone and then open it and click on the "camera" button and you're all set up. Just need to point at things and it will translate in the screen. Works surprisingly well too.

3TNB82-U

3 = number of cylinders
T = tractor or any land based use engine
N = next generation engine family
B = the emission engine family
82 = piston diameter in mm
-U = non-sleeved/liner engine block

As your machine is a non-sleeved/liner engine block type, take care not to rev the throttle very fast from an idle to high working rpms and likewise from high rpms quickly to idle. This will extend the life of the engine and many years of use.
