I did that conversion on 635CSi, Just used a new drier original P/N to get rid of old oil and added conversion fittings. Check Bentleys for wiring differences, and to see what each set runs.


I wanted to change the drier on my 535i to a R134 compliant one (64 53 8 390 469), but this one comes with a safety pressure switch (64 53 1 390 070) with 4 wires.
The old drier had 3 switches attached to it and 2 wires for each switch. I will end up with 6 wires in my old fixture and 4 in the new one...

Anyone knows what I am talking about? This only applies to the E34 before 2/89.

'89 535i and a pile of spare parts.
