Well I just bougth a conversion kit which contains the shrader valves, O-rings, and a bottle of Synthetic poly ester oil. Also purchsed a new receiver dryer.
Any recommendations on the conversion would be appreciated.
This is what I think I have to do.
Disconnect and remove the compressor and drain the old oil. Pour some amount ????? (anyone know how much?) of the synthetic poly ester oil into the compressor and reinstall the hoses.
Replace the receiver dryer with the new one including new O-rings and install the new 134a standard shrader valves.
Have the system evacuated and charged with 134a some amount ???? (anyone know how much of the R134a should be placed in a 1987 240DL?)BTW, there is no R12 left in the system, it was recovered last year.
Have I missed anything?
Thank you for any and all advice.
Jim K.
