I did this on my '91 with reasonably good success. It's not as cold as some original units, but plenty for me. I have to add about 1 can per year; this may be because the smaller 134a molecules seep thru the hoses or because my system still has a slow leak. If I recall, it took some searching to find adapters that would fit easily behind the C pillar cover and under the engine lid. I replaced the receiver-dryer and the O-rings in its connectors. I dismounted the compressor to drain out as much of the mineral oil as possible and replaced the O-rings there also. I put in ester type oil (guessing at the amount), in the compressor and the dryer. Used a real gauge set ($80 ), pumped it down for a couple of hours with a good vacuum pump. I think it took about 5 cans to get the system to cycle and blow cold air. Check the vanagon.com archives and the conversion info on aircondition.com good luck, Larry A. |
