Have you checked the coolant level with the engine cold? It has to be cold as the level will drop. You may also have a bit of air in the system, and/or check the connectors are all plugged in? It's the only thing I can think of if the coolant levels are correct.

checked the level today and its fine
red float up to the top of the cap
no leaks as far as i can see
read some where about a self bleed you can do
tried that and it seemed fine

May be the level sensor itself or just the connection.
