These are not modern engines designed to run at 192-208F. The thermostat should be 160F. A very low pressure radiator cap, and unless there is an aftermarket overflow tank, leave 2" of clear space at the top of the radiator for expansion. If you fill it full, it will just dump out 1-2" of coolant each time it's up to temp.
Ethelyn glycol can be added to protect from freezing, but it will not increase the cooling capacity of the water. Temps over 190F should be avoided, and also, cool down after a hot use is a good idea to keep from warping a 60 year old head. Let it idle for a bit after a hard work and let the temps get back down to 160 or so before shutting it off. I usually close the fuel petcock once I'm done, and let the fuel in the line and float empty out for about 2 min, then turn off the key.
The 8x1 tractors are a great strong old beast. My only complait is that few were ordered with power steering. I have a 961 and the power steering makes life on the tractor much nicer.

This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
