 yanmar 1500D overheating

I have owned a yanmar 1500D 4x4 tractor for about 5yrs and have had no problems with it until about 7 months ago and then the temp light came on after running for approx 45 min. I have done the following list things to correct the problem, but tractor is still running between 220 and 230 degrees.
1.) Flushed radiator and engine block at home.
2.) Installed temp meter to verify temp.
3.) Removed radiator and had flushed, rodded and check by radiator shop. (they found no signs of any blockage)
4.) Check fan belt tention
5.) Check and cleaned front radiator screen.
6.) Check radiator water for any signs of bubbles. (none)
7.) Check oil for water, (no signs of water)
8.) cooling system is 75% distilled water, 25% antifreeze.

If anyone has any ideas or suggestions, they would be greatly appreciated
Thank you all in advance for any help
Pat

Ok, I am in for the 20 questions, logic double check.
#1 Did you pull the thermostat and check that it was opening at the proper temperature? Usually #2 or 3 on the hit parade.

 yanmar 1500D overheating

Laughing out loud on the 20 questions, but no problem if it gets me to t he problem.. Im not even sure the yanmar 1500D has a thermostat and if it does i didnt see it in the manual parts layout or even where it would be located.. I would assume it would be around the top hose entry point to the engine. Just to be sure I will look thru the manual again and take a closer look at the hose entrys on the engine..
Thanks for the feedback,, I actually had not thought of that.

 yanmar 1500D overheating

Pat;
I have the JD version so? The parts schematics for the 1500 show a temperature sender and something else. I could not find the names for the numbers on the web. Looking at the schematics for the 1600 it looks to be a thermostat, but not the type is common in NA.
Did you have any success?

 yanmar 1500D overheating

Well Peters; Got home from work and first thing i did was go look at the tractor, radiator hose connects to a pipe screwed into the top of the engine, bottom hose connects to a pipe sticking out the front lower section of the engine, saw no likley spot for a thermostat. if there is one it might be under what appears to be a plate covering the top front of the engine under the top radiator hose ????
look thru the 2 manuals I have, but at the time i bought the tractor the only manuals you could get were for the 135D and the 155d, and I was told that these manuals were used for the 1500D also.. (not real sure I believe that, but it was better than no reference at all), anyway,, found no reference to a thermostat in them either.. another thing that now puzzles me is when I was reading thru the manual it indicated that the temp light would come on when the water temp reached 248F and go off at 233.6F +or- 5.4F. So now Im not even sure what the normal operating temp for the yanmar 1500D is.. ????? (Starting to think I should just stick with riding horses, Laughing out loud)
anyway,, thanks again for your help and suggestions because im out of ideas..

This is what I found. What is #8 and what is #12? One is the temperature probe or thermostat.

 yanmar 1500D overheating

Peters, #8 is a stud with a nut on it, #12 is the tempature sensor witch connects to the yellow temp light on the dash, about a month ago I replace it with a manual guage so that I could tell what the temp realy was. I never have trusted those lights to much. I did read an article that something to do with injector timing could cause overheating also, but have know idea exactally what they were talking about or how to even check the injector timing.
Thanks again. I will continue checking out anything you come up with..

 yanmar 1500D overheating

I hate to be the spoiler of all this good diagnostic logic, but...

These machines are built to South Asian specifications. They don't have a thermostat in most of their equipment. It would only serve to hinder the performance of cooling system under their conditions. As PK noted, they are designed to run hotter than our motors typically do in NA.

I suspect the culprit is nothing more than a defective temperature sending unit causing the light to go on at 'normal' operating temeratures. The $24.47 test would be to buy a new temp. sender and see if the light goes out, or even just ask the dealer to verify what the 'normal' operating temperature is.

Best of luck.

 yanmar 1500D overheating

I did a little more hunting on the web last night. There is a post on another site that the 1500D tractors don't have a thermostat.
I checked the 650 JD parts schematic and the area connecting to the top hose is different with a regular thermostat.
I can not find any thing that confirms the operating temperature. The marine units are low at 140 F, but have a thermostat.
Like Murf said you can double check it with the additional sender, check your thermocouple (temperature gauge) or maybe check with someone that works on them. The temperature gauge could be out a little.
