Question on 1997 BMW Z3 1.9 Coolant Flush

Hi Wayne, I have a problem with my 1997 BMW Z3 1.9 owned from new with 46000 miles on clock with full bmw service history. Just done my first work on it and changed the water pump bleeded system and ran ok on normal temp. When checking for more air and topping up I found that the top hose to rad VERY hot and lower hose Very cold? I was not happy with this so put in a new thermostat. Followed all bleeding again but same problem? Hot top hose and cold lower hose with fan heater in car blowing hot then cold when set on hot?
To me this looks like I still have air in system? followed all bleeding suggestions but still have same problem. Are you able to advise me on what to do as I don't want to use car and cause a larger problem like overheating and blowing head gasget etc.

Be patient and repeat the bleeding steps. make sure your heater is on high, turn the key on and top coolant up. Start engine, monitor coolant level, top up as needed.
