    Hello all, I am a new member to this forum, I have 99 slk 230, I bought a new compressor including pulley and clutch, can someone help me guide to install the new compressor? the unit came with a small bottle of oil, I don't know where would that go, also I don't think I have any freon left in my system, has any one DIY this? any help is appreciated very highly.

    Recently my A/C compressor started squealing like a banshee,so I entrusted the job of replacing this to my local Independent. My reason for choosing this option was that I did not have any means of pressurising the system to check the joints before taking it for a £70 regassing,so if it leaked, that money was just wasted. Also as part of the guarantee with the new compressor, I had to have a new air dryer, which would have been more joints that could have leaked. So I decided that it would be better to get them to use their gas for leak detection and also get a guarantee. Also, I had replaced, a steering pump pulley wheel that was running out of true,an idler pulley wheel and a new belt, all as a result of the alternator front bearings collapsing.All is now quiet on the front end and nice chilly air to breathe. Vehicle is a 210//300TD.

    I would advise you as I think the above poster is hinting at,;) that this is a job best left to an knowledgeable air con specialist. Needs lots of specialist experience to recognise potential snags- e.g. you are replacing the compressor-but what caused it to fail in the first place??:confused: Merely replacing the compressor may not cure the initial problem. These guys have the experience and the test rigs/ materials to get to the bottom of the problem.:bannana:

    The silver one.
    Oil goes into the compressor via the pipework, best find someone local as whilst you can fit the compressor easily enough you may find they wont be all that helpful in the gassing up dept because you fitted the new part, and if theres a prob whos fault is it?, let them fit it and gas it sorted.
