a/c accumulator/dryer

[oliver12]

Ok im gonna try and get this a/c working im retro fitting to 134a. I purchased new orifice tube and accumulator and need to add a few ounces of oil to dryer. Anyone know which port to pour it into ? Or does it matter?

The compressor needs to be removed and make sure no old oil is in it. Pour half into the accumulator (port does not matter, oil circulates through the entire system), half into the compressor. Change out all the o-rings, put it all back together, pull a vacuum for about 30 mins and shut the pump down. Take the reading and walk away. Check it again an hour later if the reading is the same, turn pump back on and come back next day (really a few hours is sufficient, but better safe than sorry). Remove pump, charge and enjoy.

When you pull the old compressor and dryer off flush the lines to get all the old oil out of them too.
