Usually with a cross-flow radiator, on a cool engine, drain some of the coolant down till you can see the top coolant passages if possible. Remove thermostat, hook everything back up, the coolant flow is instant when you start the engine. If very little or no coolant flow in radiator, maybe a clogged engine block or radiator?
If you suspect the coolant sensor is faulty, replace it, I don't think it costs much. Give me a second on that sensor.
