Agreed, cooling should happed via airflow through the radiator, not flow
through the engine.  I recommend leaving at least the low temp thermostat in
place so it can close and let coolant heat up, that way your heater will
work.  Also, you should always have coolant flowing through a warm engine,
and use a fan thermostat to bring on the fan if coolant temps start getting
high.
