    Another question what causes the starter not to engage fully? I replaced the ignition switch and replaced the starter with an O'Reilly rebuilt starter. This is the 3rd O'Reilly starter I have gone through in the last 11 months. This current starter is not engaging fully with the fly wheel at least 30% of the time. The starter motor is a Bosch but the solenoid is another brand according to the manager from O'Reilly's. I have a Mean Grean reduction starter on the way because I am tired of these rebuilt starters.

      just get a bosch starter...you'll be fine. The o'reilly starters tend to use worn out internals that fail under the load of a diesel engine

    Hi Pierre. In my 380SL sometimes the a/c works perfect and sometimes is dead. There's no blower nor nothing. I think is an electrical problem. Where do you think I have to start checking? Thank you!

    My 84 300SD AC belt jumps around, squeaks, sqawks and flaps. The AC itself works fine. Compressor seems fine. It has a new belt from Oreillys. The dimensions are 13 x 925. In your videos you mention it is really 12.5 x 925. Does 1/2 a mm make a difference? I recently ordered a genuine merc AC belt and will try it but the dimensions are 13 x 925 on the one I just ordered. Thoughts ?

      buy your belt from mercedes. the design is totally different. set it tight- 5mm of deflection or less.

      @@mercedesclassicswithpierre1753 Just finished following your recommendation. Installed p/n 0049979392 sourced from Mercedes. New belt is a world of difference from the one I had installed previously. The AC belt is tight as a drum now and smooth as silk now. Thank you.

    Freon is illegal in US and Canada since Jan 2020. What other refrigerants can we use?

    I've seen some people just recharged their a/c when it's gone. Others will empty their refrigerant before recharging. Which is the best way? Most importantly if we emptied our refrigerant with a vacuum pump, then how do we dispose the old refrigerant?

    By the way what are your thoughts on the Klima Design Works after market system as an update for the 1981 Mercedes 240d?

      good question. I think the r4 is still a good compressor...however, I wish there was a way to use the nippon denso.

    Hello , I have a 1993 Mercedes Benz w124 E220 . The AC randomly work. It’s very cold when normally work but no cold wind blowing after driving 20-30mins
    Sometimes it’s ok if restart the engine but sometimes not.
    Clutch can’t run when no cold wind. Relay , ac pump were changed a brand new parts; high low pressure r good
    Is it the problem of the temperature sensor?
    Pls advise
    Thx so much

      I think you have a weak belt tensioner when the ac is hot, is the clutch still running? check for a loose belt first

      Hello, thanks for your reply
      The belt and the belt tensioner (pulley only) were replaced by the brand new one also.

    I have a 1981 Mercedes w123 240d. The a/c was working until about 3 days ago. The low side is about 100 lbs. the high side is about 200 lbs. What is going on?
