How difficult is it for 'me' to change my AC compressor on y 89 190E 2.6? is it an extremely tight squeeze down there? Would I need any special tight spot tools to do it? As far as capability, I have it...already done most of the car's work myself. I haven't been under it to investigate the compressor mounting yet. I'll be changing the oil shortly @ 228,000 miles! and I'll look closely while I'm under there. Compressor died last summer.
