Hello,

When I went to fill my reservoir tank, I was only able to get about 3 liters in the system before it stopped filling up. I drained about 5 or 6 liters of coolant out of the system so I know there was at least that much in there when I started. I've tried opening and closing both bleeder screws with the engine on and no luck getting any into the system. The top hose doesn't heat up, so I don't think coolant is flowing. Any ideas?

Sounds like trapped air. Can you share a photo of the tank you are filling?
