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.
