1) does your oil look like oil? or milky with coolant?
2) exhaust smell sweet?
3) adding coolant all the time to keep it full?
The above tends to indicate maybe blown head gasket, or cracked head.
If none of that is going on, you might have a bad coolant temperature switch, thermostat, radiator cap, etc. Let us know more details if possible. How many miles on the engine?
Or maybe the radiator is clogged and needs flushing... there are lots of possibilities based on what you've said.
MOST IMPORTANT: Find the problem soon. If you drive the car when it's in the red zone you can probably kiss the engine goodbye.

If you find that the radiator is just no good (damaged/rusted out/whatever) and you want to replace it, make sure you get a twin-row radiator ... they work a lot better. I've never seen my temp gauge over a tad over halfway, even after hours on the freeway, with a new twin-row radiator.

have you checked the coolant level? is it full?
when the fans come on, does it stay at normal temp?
radiator could be shot as well.

Possibly, a Subaru TSB (Tech. Service Bulletin) published in the late eighties
spoke of a ground connection at fault when this occurs.
This ground point is under the front pass. side intake manifold bolt.
It is the ground for all dash related entities.
Second, all the flushing products methods on the planet will not do anything
except make your wallet lighter.
The problem with your radiator is external not internal
The fins connecting the coolant passages have delaminated from the tubes
and therefore are not "wicking" the heat away from the tubes.
Here is what you will likely find if you take the time to remove your rad.
If you want to fix this follow the advise above and get a new twin row.
