Maybe someone can enlighten me.... i am totally out of ideas...

Bought the 89 wolfsburg two years ago and the temperature gauge was almost
always at the bottom end of overheating. Since then i have replaced almost
everything (exact description following). It is still riding at just below
the lower overheating mark until I go highway at about 4,000 rpm and then
the temperature gauge comes down to a little above the light in the
temperature gauge in the pannel... as soon as i am back in stop start
traffic it goes up again... I am not running with air conditioning and
there is no air in the coolant system.

Here is everything that I have replaced or checked on....

1. New Radiator, new lower temp sensor for fan. (Fan working fine both
stages). (comes on once i a while)
2. Installed all New heads, piston rings (the old heads were both junk,
cracked in between each valve, so probably overheated)
3. Good newer waterpump, no visible wear on it at all
4. New thermostat
5. No cracks in overflow or coolant reservoir
6. new rear heater core
7. correct voltage at the temperature gauge in instrument panel.
8. not using any coolant.

Any ideas would be super!!!! I am totally out of ideas.
