Where do you add oil after replacing AC evaporator for Saab 2001 9.3?
I am replacing AC evaporator and need to add oil. Can the oil be added directly to the new evaporator before installing? If not where is the proper place to add the oil?

There most likely is no need to replace the oil as oil travels with the gas
it is normally put in through the compressor but the amount is critical as excessive oil will block the TX valve
now that you have replaced the evaporator, take it to an auto ac specialist shop , have the system evacuated right down , any oil required to be added and the correct amount of gas to be installed
Thank you for the suggestion. I will go ahead and install the evaporator and take it to a AC specialist to be evacuated and have the recommended oil added based on what was lost when removing the evaporator.
