Confirm if the top and bottom hoses (0f the radiator ) are at the same hot temp ( when upto engine temp) if a difference in heat between the two Hoses . Problem more likely to be the thermostat ! Replacement required followed by correct collant re added and coolant system bleed correctly. . Cheers .
