I just had the radiator/thermostat replaced (Dec.2000) in my 84 300DT and experience the same simptons. Prior to change out temp always just a nudge above 80C, now is runs just a nudge below the 100C. Another curious thing, the pressure escaping when opening the expansion cap is dramatically less than before. The old radiator leaked at the top tank, thus the need for replacement, would this leak cause it to build more pressure in the system? Counterintuitive I know but it just seems odd.
