I have owned a 2N since 1987 and have always used it without a thermostat. I have been doing some service on it. Going back on with the radiator I decided I would put a thermostat in it. It seemed that almost all of you recommended it.
Now with the thermostat installed after running my tractor for a few minutes it overheats. There is steam coming from the top of radiator and I cannot keep my hand on top of it. To hot. I installed it with the point of thermostat towards the radiator.
Thanks for any ideas
