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.

Electric Fuel Boost Pump
I installed Kent's Electric Fuel Boost Pump kit 3 years ago and it has been working great until recently. It's clicking away really fast. I pulled the bleed plug out of my filter and the pump is barely pumping the fuel/veggie oil. I disconnected the fuel line right before the lift pump and very little WVO is coming out of the fuel line. Did same thing right before I.P. and again the fuel is barely coming out of the fuel line. Yet the EFBP is pumping like crazy. Does the EFBP just need to be cleaned? Can I take the EFBP apart to clean it out or is it just worn out and time to replace it?

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.

W124 Steering Box Interchangability
Are all steering boxes for the W124 chassis interchangable? What are the limitations to swapping if there are any?
To be specific, I have a 1992 300D 2.5 Turbo with a far-too-far-gone steering box and not much money to fix it. So I'm trying to figure out how wide I can cast my net at the ol' pick-a-part, so to speak.

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?
