Have a 1995 E220 (W124) 160 000 km which runs hot (100-110) when driven slowly around the suburbs (putting the baby to sleep stuff) On a long trip at 130km/h it sticks at 80 I've spoken to a couple of other owners who say it should stick at 80 no matter what. Thought of having the radiator (and engine?) flushed. Any suggestions/experience. Thanks in anticipation.
