It'll be 105 here today also, but we would not expect to see a reading of over half unless the tractor was being worked real hard. Maybe you need to at least temporarily install another gauge to verify the accuracy of the dash unit?

Could be the gauge, could be the thermostat isn't opening all the way, restricting the flow. Thermostats are cheap, I'd invest in a new one, having gone this far. But, the good news is it's running now!

"the thermostat must be open or I would not have been able to flush the system...."

You must not have a thermostat, or I doubt that you would have been able to flush the system with cold water without removing it, (it would never open). The ambient temp. or how hard you work your tractor should have little or no effect on the tractor's temp, (with a water pump). My YM2000B gauge doesn't have degrees on it, only marks, but it never gets above 1/4, (160-170), in any weather or usage. Here is a SunPro gauge, and as you can see, 3/4 is about 235 degrees, (HOT). http://www.tractorbynet.com/forumfiles/678521-sunprogauges1.jpg

That thermostat could be stuck open. So you still might have one that isn't any good. I would check and see. I understand that sometimes they will run hotter without a thermostat. From the old days some people would take them out of the old Ford cars and they ended up running hotter. Something about the water moving too fast, it don't have time to pick up the heat from the block.

the t-stat shouldn't have been open when you flushed the engine .It opens when the water gets hot.It should have been closed when you flushed.

Does it seem incredibly hot? I am guessing it is ok at 3/4. I am not familar with your unit though. Do you have a manual?

Ok, so you all have found something for me to do on my next day off....At 3/4 its still hot and the fluid is boiling in the overflow. Can someone tell me where I can find the correct thermostat to use in this FX20D. Based on the posts it sounds like the thermostat is probable stuck open, as I flushed the system this past weekend by placing the garden hose in the top of the radiator and letting it run out of the top hose...I recall it being cold.....Can I locate and purchase one quick?

Thanks again
Scott

Slow down and think about this. As I said before, if you have a thermostat, it will be located in a housing where the upper hose attaches to the block. Is it there? Also, have you proven to yourself that the water pump is actually pumping, and not sheared or anything like that?

thegreatrandini · Jul 26, 2005

Norme is smart in say slow down and think about it.
Hoye tractor should have a thermostat!!!
I don't think that is your problem.. I don't buy the water don't have time to take in the heat thing. My cars always ran cold without the thermostat...
I bet your water pump is bad or you have corrosion in your engine or your Thermostat is stuck shut not open......

First place I guess you weren't driving Fords back in the 40's they ran hot without one. It would have to be stuck open for the water to flush through, if it were stuck closed the water wouldn't go through it. Think about it, its pretty simple. And like has been said, he needs to see first if he even has a thermostat in it, or can have one in it.
