W110 W111 W112 Sedan, BENZ AID - COMMON QUESTIONS AND ANSWERS

Whats the proper way to bleed the coolant lines for an 84 300SD. I have just acquired an 84 300 SD and have put in a new thermostat. I turn the car off when the temperature gauge is just shy of the mark between the 80C and 120C (I assume this is 100C). There is also no heat out of the heater where there was once before. So I probably still have air in my collant lines. What is the proper way to bleed the coolant lines? As an aside question, is there a way to tell if there is air in the coolant line versus the thermostat being bad?

Will the manual for front seat repair help me with my model. I already paid for this repair once and and was wondering if we can do it ourself with instructions in the manual. Appreciate ur input.

I just got hold of an 84 300SD with 87,000 miles on it. I haven't started any of my initial maintainance yet (filters, hoses, compression test etc). There were no maintance records with the car so I will be replacing a lot of the "minor" stuff. It starts great on only one crank and shuts down perfectly as well. Not having owned one before I don't know if what I am seing is normal or not. When you press down on the accelarator there does not seem to be a direct response from the engine(rpms). It does climb up there though.

Hi--I recently acquired a 1981 300D--upon closer inspection of the underside, I discovered one of the former owners covered up the jacking points with metal (I am guessing to patch for rust). In any event, I am now wondering what options I have for jacking it up seeing as the jacking points are covered. I am working with a floor jack and jack stands--I have worked with trucks before but not a sedan so I am not sure what my options are as how to get around this problem. Any advice on how to go about safely jacking it up would be appreciated, Thanks, Archie
