Hello:

Recently, I bought a Volvo R134 retrofit from fcpgroton for my 87' 240DL and I'm just wondering if somebody can help me clarify some questions before I start dismantling things. In hand is a volvo copy of the original how to instructions downloaded from this sight plus some accumulated ideas from reading this forum. Here are my concern since volvo is not customer friendly enough by not attaching any info. in the box.

1. Does the new evaporator,hose line,dryer needed to be oiled to certain amount before installation? If yes, then I have to buy more since there's only one for the compressor.

2. Do I need to removed the condenser, flush it clean then re-oil it with ester oil?

3. Is it ok to purge all lines with pressurised air knowing that it might re-introduce moisture into the system?

4. Is there a better way to remove most or all the R12 oil from the compressor like a chemical maybe?

5. Concern of orifice calibration from old messages, is the new one ready for use? or needed some adjustment.

6. The pack of O-rings from the box is it complete? or do I have to buy some more, like for the compressor lines high and low.

Thanks! Any help is appreciated.
