It moves the hose; what moves the hose?

Lube the radiator port and the hose connector O-ring with brake grease (synthetic grease) and with the clip fully inserted, push the hose on the radiator port until the clip is clicked over the port barb.

You still have air in the system which might cause the coolant light on/off.
