Some final R134a A/C questions before repairs begin...

[morebhp]

Guys, I have all the parts I could find for my A/C repair job but I have a few lingering questions.

1. Which oil should I use when I add to my new accumulator. POE? PAG? I still have the OEM Nippon Denso compressor. The system is R134a from the factory.

2. When I add the oil to the new part... where to I poor it into? The long end that goes into the fire wall or the short tube that comes out the bottom of the canister?

3. Those little quick connect adapters that go on the schrader valves on the replacement parts... where do I find them? Which ones do I need? Anyone recall? There are hundreds out there it seems.

Thanks!

1. Either oil will work fine since the system has always been 134A. POE however is compatible with R-12 oil for retrofit.

2. Depends on what you are replacing. If you are replacing the ACC/Dryer than you need to add the corect amount to the new acc/dryer etc. Its also desirable to drain and measure the oil out of the old components so you know how much you need to add. The entire system uses a certain amount of oil and certain components trap oil in them. Don't want to over service the system with oil.

3 Oil that doesn't get added to components prior to closing the system gets added thru the low pressure servicing port. This however is primarlily for adding oil during a servicing. So if the system is open you could just add the oil to the open line then close the system.
