did you 'burp' it? modern cooling systems trap air, you have an air bubble.

Default your water pump is toast...

...if you see no coolant being pumped back into the resevoir, then your water pump impeller is busted. Probably got big plastic chunks lying right inside the block.

no, only the coolant recovery tank has a cap...

see Rocky's comments /\ /\

the OEM pump has a plastic impeller, known to shatter/break. When it does, reduced or no coolant circulation is the result. You have to remove the pump to inspect it. If it is bad, replace it with a new metal impeller pump only, OK...

The impeller is part of the water pump

many suppliers carry the improved metal pump:
ECS Tuning, others... try a search for this
