[W126 Coupe] Nippondenso Compressor

[Chet Hwilka]

Hi Dan;

I went through this with my wife's 190E (similar A/C system).  I started by
simply recharging with the R134A kit, but eventually had to tear down the
whole system.

I cleaned/flushed everything up as best I could, but the compressor started
making noise, so I tore it down again and replaced the compressor with a
used one.

Good Luck
Chet
