Randy, I have seen people tap the head at a water jacket and get a sending unit also I have seen a radiator hose cut and a section put in to accept a sending unit but as for a factory spot there is none.
As long as the cooling system on these engines are in good repair it is almost impossible to over heat.
Here is a pic of the same engine in a Ford truck with the temperature pickup guage installed in the block -- It is just in front of the oil filter assembly.
One of the best things done by Ford on this tractors was to install an extra large cooling system. The tempature that you really want to monitor is your cylinderhead. Too hot and you will warp your cylinderhead and blow a headgasket. On your flathead, there is usually a flatboss up by the water outlet that it oftentimes drilled and tapped for a temp sensor by the brave.
I have never done this myself, but I have seen it done numerous times. You can also install a "T" in the radiator upper hose for the temp sensor.
Oh yeah --- you have something else wrong there buddy. The N
should never overheat unless you have a major problem in the cooling system. Did you check the water flow out of the radiator?
Do you have a fan shroud? Is the radiator packed with debris?
Hopefully it is not something major. Let us know!!!!!
Popping this up becouse I am thinking of adding a guage to mine.[Why? who knows. I have the guage and figure"what the heck" ] Now my N does not have that boss on the side like the later ones had. Anyone hear of drilling a head without that boss? I would much rather mount the snesor in the head, beciuse thats the most important place for it.
