85 500SEC R134A conversion

500sec on Wed June 15, 2011 5:06 PM User is offline

Year: 85
Make: Mercedes
Model: 500sec
Refrigerant Type: R134A
Country of Origin: United States

I have a 1985 Mercedes 500sec with an A6 compressor. The car has been converted to R134A before I bought it. The system has very slowly leaked down. I will be replacing the dryer and evacuating and recharging. Do I add any oil with the refrigerant like with an R4 compressor or is all of oil needed in the sump of the compressor?

If all you're replacing in the drier. Add 1.5 to 2.0 ounces to the new drier.

I don't know what type of oil was used when the car was converted. I purchased some BVA Auto Ester Glow from ACkits.com. Will this be OK?

BVA Auto Glo is a very good oil for conversions.
