Refrigerant: R134a My Coupe GT has been retrofitted to R134a by a local wrench. He told me the system might be "slightly overfilled, but not enough to be a problem." Well, I checked the low side pressures over the weekend it was well over 50lbs. That too high for my comfort. So I bled off some and rechecked. Well, now it was too low. Grab a can, tap it and throw it in. It sucked in in in seconds flat. Something must be wrong I thought. Look the now empty can more closely and IT'S A 11.5 OZ CAN OF R134A OIL!!! Eeek! So now my system has the original oil the mechanic put in (11 oz according to the sticker) + 11.5 oz that I added! My understanding is that the extra oil will just accumulate at the bottom of the condenser or evaporator. Can anybody confirm which? Or is it both? Will it cause harm? Also, how do my pressures look? Too high? Too low? around 45 static (engine & AC off) Yes, I have a pusher fan. It's actually the readiator fan out of an early 1980s Honda Civic. Seems to work great. I wired it into the +12v for the AC clutch so that it comes on whenever the AC is on. I sort of cooling fine. On the way into work it reaches decent temperatures(45-50*F), but on yesterday's trip home in 95*F with lots of sun it only dropped to 58*F and that took about 45 minutes, it dropped to about 65* very quickly but took for ever to come down further. I'm not sure how much R134a is in the system, it was WAY overfilled by the idiot who did the conversion, so I bled some off, realized I had bled too much off, went to put some more back in, accidently added 11.5oz more oil, then added R134a until the low side pressures were what I considered to be right. Will evacuation of my Coupe's AC system remove most/all of the oil in the system? If evacuation does not remove the oil, any suggestions on how to get it out? Or should I even worry about it?
