[W126 Coupe] Air-conditioning condenser

[Dick Spellman]

Hey Markus, you got the components turned around a bit. Condenser is up 
front of the radiator, evaporator is in the dash. Steve, give Jonathan a 
call (404)805-1357 and he can set you up with the genuine replacement 
required by your compressor mfg. You should do the receiver/dryer once 
you open that system up again too.
Are you doing this yourself or using a shop? They may recommend the 
expansion valve ( a real fun job) be replaced as well and a complete 
flush followed by compressed nitrogen to clear any remaining debris if 
your compressor suffered the black death as it's sometimes called.
