To Lee and All,
My '92 400SE runs at about 87-90 degree without A/C and 97-100 degree with A/C on(all during the night, outside temp. 18C). How about other MBs??
My car used to run cooler than now(about 85 degree with A/C during a 33 degree summer day). Is it because of engine wear?? Or the tuning of the engine when the car is serviced(of my knowledge is that MB has changed the engine management computer in late 1994 to get better fuel economic/emission,).
