Hey All,
So i bought the R12 to R134A retrofit kit from advance auto and the low pressure side adapter fitting doesn't seem to fit my receiver/dryer.
I am thinking this kit is for domestic cars only??
Did I just lose my $12.99??
Well, doing it 'right' would consist of getting all the mineral oil out of the system and refilling with pag 46.
Pag oil is incompatible in former R-12 systems. Use esther oil as recommend by Volvo.
OP do you have a copy of the conversion greenbook?
Yea i plan to buy a new compressor and condenser and bought a new receiver/dryer. I tried the retrofitting low side adapter on the new receiver/drier but it acts like it wont fit. Maybe its user error.
I bought some ac gauges and plan to vacuum the system etc. I don?t see an oring for the low side adapter, should there be one?
I'm just telling you what the greenbook says to do. If they thought PAG oil was the correct lubricant, they would have specified its use.Why is that? Pag 46 is incompatable with r12 itself. But removing all mineral oil, filling with pag 46 and r134a works totally fine.
Source: I’ve done it multiple times.

Yea thats why i was asking. I plan to replace all. Rub them with oil prior to fitment?
I need to get the low side figured out as far as the 134a adapter.
Receiver/Dryer was bought from ebay, not sure if that matters.
How necessary would replacing the evaporator be??
Replacing the evaporator seems a little extreme but I would replace the expansion valve.
The bill for conversion under that service advisory even back in '95 surly would be well over $1000.
