If you still have an 8N ford tractor in service on your farm, it is likely that you have taken good care of it over the years. After all, the 8N tractor is quite old. Regular maintenance on old tractors is a must, but one of the overlooked items on an 8N tractor is the thermostat. If the thermostat fails, it could leave your engine overheated and you stranded in the fields.
Follow the radiator hose from the radiator to the location where it connects to the engine of the Ford 8N tractor. Remove the hose from the engine by loosing the clamp that holds it onto the water pump with a screwdriver. Pull the hose off the water pump.
Pull the thermostat and the thermostat out of the radiator hose. The housing for the thermostat is located inside of the hose. The thermostat sits inside of the housing. If the thermostat you purchased came with a new thermostat housing, pull the housing out of the hose.
Place the thermostat inside of the radiator hose and housing with the thermostat pin facing out of the hose. If a new housing is being used, place it into the hose first. Position both pieces in the hose so the pin slightly protrudes from the radiator hose.
Place the radiator hose back onto the water pump and secure the clamp.
