Hi All,

Before you go through the harrasment and hard work of changing thermostat, dismantling radiators as well as doing radiator flush due to high temperature readings, please check the ground and also try and replace the temperature sender. I have suffered first hand with insanely high temperature readings only to find out that I had a faulty ground and a defective sender, these two problems are quite common with MB, specially the older OM 616/617 and 603 series.
