1985 500 SEL coolant temperatue

1985 - 500 SEL When starting the engine from cold, the coolant temperature slowly rises until it is up in the red zone, above the 120C marked on the gage. The temperature stays there for several minutes, then drops down to 80C where it will stay. The coolant level is correct and the thermostat has recently been replaced. Is the new thermostat sticking or is this normal behavior? It worries me to see the temperature gage that high.

1990 300 SE trouble starting after driven short distance

My 1990 300SE runs fine normally but lately when I go out and start it it starts fine but if I drive a very short distance or kill it and try to resart it it turns over and sounds like it is mis-firing and won't start. This is happening more and more often but not every time. After I finally get it started it runs fine in park but if I put it in gear it sputters and dies this happens over and over and then eventually I can get it started and go. While it is doing this I can rev the engine up in park and it runs great but as soon as I put it in gear it dies.

300sd 1982: Electric surge under console drains battery

Dear Friends!
I am an owner of MB 300SD 1982. Recently, the car presents disabling electrical issue which I hope to pin point eventually. There is a electrical surge somewhere under console ( I can hear climate control clicking) which drains all electric charge (battery). When it happens all my dashboard indicators go wild. Surprisangly, all fuses stay intact. I suspect it may be blower engine goes bad, but I am not sure. Anybody had this problem before?
