Klimakompressor

[Erich]

Tja, das musst Du selber entscheiden, ob Du das kannst. Ich hab schon einige aus-/eingebaut aber am M70 Motor, ich hab aber ne Grube und auch Vakuumpumpe etc um dann nach neuem Einbau Vakuum zu ziehen, den Trockner sollte man dann auf jeden Fall tauschen. Wenn noch Gas im System ist, muss man das vorher absaugen, kannste nicht so einfach in die Luft ablassen. Engl. Anleitung ist hier drin fuer den 735 ab Sektion 640-13
