well i dont know what to do now my series one is still over heating.

ive changed the thermostat hoseing the thermostat put new seals on.
replaced the hoses
put a new(ish) rad in
new fan
new temperature sensor
new water pump
flushed the engine thro 3 times
new gauge well extra gauge

but still it gets very very hot and over heats even if im driving on the motorway witht the fan on it will over heat has anyone got any other ideas?

i have checked the rad for cold spots and it seems fine i have bleed the system again fine the gauges seem to be working but i put a new temp sender in anyway.
i really dont know what to do now.

is it possible the head gasket may have gone?
as the car runs fine and is no sigh of oil in water or vice versa.

any help would be much appriciated

ive also given it an oil change with new filter and cooler
