I’m not familiar with a Ford 2N but here are some basics. The radiator allows heat to be transferred from the water to the air. You need good air flow through the outside of the radiator, good water flow through the radiator and good water to radiator contact which can be impaired with “crud” that forms inside the radiator.

To help out, carefully (I don’t know if that is a pressure system or not) take the radiator cap off and run the engine and look to see if you have water flowing in the radiator after it warms up a bit. If so then chances are the water pump is working and the thermostat is opening. If you don’t have water flowing it could be either the water pump or the thermostat causing your problems.

If you have good water flow, then the radiator may be dirty either on the outside or on the inside. Back flushing might help, but if the radiator is dirty on the inside it will probably have to go to the radiator shop.

One other thing to check is the ignition timing. Late spark timing will cause an engine to run warm.
