Engine Size: 2.2l
Refrigerant Type: R12
First post and great info here!
What are the consequences of installing the receiver drier backwards with the refrigerant flowing out of the "in" port?
I am restoring this vehicle for resale and do all of my own mechanical work to this point except a/c. The system was not working and empty when I acquired the car and I paid a local mobile a/c tech to check over the system and a new compressor, txv and drier were installed. The system was flushed, leak checked, evacuated and charged.
It now blows cool but not as cool as it should and in checking over the system I see that the drier was installed wrong. I can't get the tech to return my calls at this point so I know I'll need to take it to a shop to recover the gas and replace the drier.
Is this a simple deal or will it need to be flushed and txv replaced again?
Thanks in advance for any advice.
If you see a cut-away of a receiver-drier, the outlet tube to the expanison valve is low, so below the liquid level in the receiver-drier, so that only liquid goes to the expansion valve. The inlet tube to the expansion valve is higher up, from the condenser. So installing it backwards would allow gaseous refrigerant to go to expansion valve, adversely affecting cooling.
If the receiver-drier is installed backwards, you'll need to recover the refrigerant, install it correctly, then evacuate and recharge. There should be no need to actually replace the drier, and shouldn't have caused any damage, unless I'm missing something here.
Thank you very much for the info, I appreciate the help.
Oh, and nice avatar!
