The top of the red float must be level with the top of the tank. You have added too much coolant to the system. The tank needs an air cushion for proper operation. The coolant level is not visible inside the tank. Drain some out via the drain ok on the underside of the radiator. (I can't believe they censored this word!)

Unlock the cluster and monitor the actual coolant temperature, test #7. The coolant should not rise above 108 deg C.
