Inspect the cooling system? 200 1980

Thanks for the info. Just had the sensor in the head replaced - not overheating - it was apparently a false signal.

However here is what it is now doing.

When I shut down the needle drop well below C and I can't even see it except if I look to the side.
As it warms up it stabilizes at 9 O'clock and stays there - until I select heat and turn the fan on then it drops to 25% - between C and 9 O'clock (happens immediately) - so likely an electrical thing. When I turn heater blower off it goes back to 8:30-9 O'clock.And when idling needle wanders mostly downward and looks jumpy 'sticky' Erratic.

Where and what should I look for next ?

Much appreciated. At least I know it's not overheating.
