Too Hot?

[coosa]

I emailed Bobby at Fredricks and gave him all the info I've shared here and asked if he thought I had a problem. He said that I didn't; all the temps were normal and that I should be careful to not overwork a small diesel like I have. He said that every tractor is different in the way those temp gauges read. I think he meant that one that showed the needle at the middle might be running the same temp as another that shows it at 1/4.

Thanks for all the help and replies; I'm sure I learned some things from the thread. A good evening to all!

thermostat ? I don't think mine has a thermostat. Do any of these have a thermostat ? If you are concerned, maybe you could add 1 of those small elec. fans in front of the radiator.. Just a thought

is the block clean? Unless Fredricks specifically back-flushed it, it could very easily be plugged.

Bobby is misinformed. Your tractor is running hot, (IMHO). I have never seen a gauge erroneously register hot but otherwise appear to be working.

Some Yanmars do, some don't. It's a good bet that if Hoye does not show one it does not.

I can totally see that. I had thought that as an option. There idiot gauges and can be out of calibration. That's why you would need a really good gauge on multiple tractors to see if they indeed run at similar temps. And then there still would be varations for all types of things from ambient temp to condition of cooling system as well as individual radiators. That's why operating temps are given in a range.

So many tractor owners have said that here that it really makes me wonder. Of course, the gauge isn't reading hot; its only just past the middle mark and the outside of the block never registers above 160. The needle is still a long way from the red mark on the gauge. I wonder if reaching the red mark on this gauge would correspond with the light coming on with a system with no needle?

I think I oughta hook up a real temp gauge with numbers on it. Can anyone who has added one of these post some pics, tell me what you bought and where you got it? Thanks!

Block is clean and outside was painted. Installed new sleeves, bearings, pistons, rings and head. (I wonder if the head is used?) Also radiator, water pump, and thermostat are new. All of the things that would normally make a tractor run hot are nearly new. I don't see anything on the form saying they back-flushed the block, but they told me they steam cleaned it. Wouldn't that have taken care of any issues?

Here is what I did when inbstalled guages.

A mechanical water temp gauge is very easy to check. I always take any new ones and put the probe in a pan of water alongside a digital thermometer. As the temps rise, just compare the two as the process continues.
I've only had one that I took back, after the gauge hit 160 degrees, it sort of stuck and hung until the water reached boiling.
