I have a mercedes s 350d-W140 1993 year. When I take out the wire out of cooling temp/sensor,gage does not drop to zero.when I plug again and I drive,gage is erratic.when I top the accelarator,sometimes it drops a litle or goes higher a litle.and the angine temperature,goes to 180 F,BUT DOESN?T BOIL water over.when stop feel with hands the radiator from the inside looiking at the engine,right side is hot,left side is warm,and the lower thermostat hose on the left side,is cold.when the uper hose on the radiator,its hot.when you sut the car,and wait for an hour,the same upper hose is flat,like sucking air. those happened on a rebuild angine,and I have changed water pump,thermostat housing,and thermostat. I am looking forward to hearing from you soon. Best Regards Giorgos
