Engine overheating
Can old antifreeze cause the engine to overheat. The tester shows that it is still okay for minus 45 degrees celsius.

If your radiator has never been professionally flushed, that would be the first thing that I would do (as mentioned already).
I doubt your's has an electric fan, but (as also has been mentioned) if it does it would be a prime candidate.
The fact that it heats up going up hills indicates that the cooling system just isn't up to par. A loaded vehicle going up a hill in warmer weather is the test for all cooling systems. That is about the only condition that makes the cooling fan come on in our Sprinter unless we are in really hot weather.
