Continued my coolant top-up operation. Refilled tank again and brought engine up to full temperature. Gauge stayed in middle, radiator fan came on high-speed. Coolant tank overflowed so I stopped engine and screwed top back on tank and reconnected hose. Ran engine again and coolant went down a little more. Still NO coolant came out of thermostat bleed valve.
