I am getting ready to replace the receiver/dryer (accumulator) on my '95 850T. I have the receiver/dryer, o-ring kit and orifice tube from FCP. I have the r134a, PAG oil, vacuum device, and good gauges. I have been recharging the system for the first half of the summer, but recharging has become too frequent. Two independent diagnoses say that the evap is ok, the Volvo dealer says that the receiver/dryer is the problem (pd $100 for the diagnosis).

I don't have the coupling tool yet, but will make a run this afternoon to the local parts store. I checked with Volvo and they wanted $50 for the tool and couldn't ship it until September 15th.

My question is, where is the orifice tube located?

I will post pictures of the job when it is complete.

    I bet it is your evaperator. I also was told no leaks. But eventually it got so bad that it showed up. The evaperators are prone to leak freon on the 850. Swedish Engineering sold me everything to fix the problems with the original evaperator. Unfortunately, this usually damages the clutch in the compressor for all the clicking on and off. I replaced my compressor with a used one and it has the same problem with the clutch. Good luck to you.
