JmP6889928 Posted June 16, 2013 Share Posted June 16, 2013 Accumulator is the big silver can that is on the A/C lines, usually in the passenger side rear corner of the engine bay. You will want to use PAG oil and depending on where you live will dictate the viscosity of the oil. Ask your parts store which viscosity they sell the most of where you live and purchase that.

JmP6889928 Posted June 16, 2013 Share Posted June 16, 2013 Not having ever actually worked on a Subaru A/C, I do know that some vehicles have the accumulator in an end tank of the condenser. Maybe that's what you are seeing on rock auto. Link to comment Share on other sites More sharing options...
apexi Posted June 16, 2013 Share Posted June 16, 2013 I don't know much about AC systems, but hopefully the attached images help. http://thumbnails106.imagebam.com/26060/5a57ef260598196.jpg Link to comment Share on other sites More sharing options...

apexi Posted June 17, 2013 Share Posted June 17, 2013 I think what you're looking for is actually attached to the ac condenser on our cars, the cylinder on the left hand side in the first attached picture. I see the drier/accumulator part that rockauto lists, and from the pictures I've seen it looks like you put that inside the cylinder. Link to comment Share on other sites More sharing options...
jp233 Posted June 18, 2013 Share Posted June 18, 2013 Yes that is the drier, it is basically a dessicant that acts as a dryer and a filter. You will want to replace that with the compressor, before you pull vacuum down and charge it with 'fridge. And check/clean the expansion valve at a minimum, replace if necessary. On a lot of vehicles, it is a big aluminum can that sits between the evaporator and the compressor (LOW pressure side). It's the can that gets ICE COLD and sweats (exterior condensation) like crazy inside a hot engine bay too. You need to read the FSM about the HVAC system. It recommends Denso Oil 8. I don't know if that crosses to PAG oil or not, but PAG oil comes in different weights, 46, 50, 100? Normally there is a sticker in the engine bay that talks about AC oil and R134a amounts. The FSM says min 370g (0.82lb) and max 430g (0.95lb) of R134a, and to maintain 18-28psi LOW and 213-242 psi HIGH with ambient conditions of 86-95 deg F.
