Good evening wayneh,
Kubota's temp guages are some funny creatures. They will make you feel like they are overheating, but trust me, they are not ....
Go to this thread, it shows some drawing of such ~~~~

It was awhile even before I thought my fan was even working. And God as my judge, I thought 1,000 times that mine was going to overheat, but didn't.
Rule of thumb, if it is not in the red, it is running normal ~~~~ that comment come from two well known Kubota mechanics from down here in Louisiana ~~~~
Now, let me state this, the older RTV units, had different sending units on them, the ohms read different , and they read so much different that the ones we have had for the last two years ~~
When the thermostate opens up, and the fan kicks in, that temp will fall fast, that is the way it's designed to do ~~~~
Hope this makes you sleep better, after learning this, many of us did !!!!!!!!
