Good info to know. I shall heed your recommendations.
And as always, very grateful for your assistance. I'm glad to have happened upon this forum.

True regarding the scribbling of data...I actually remembered to take pictures during the charging, with a final picture of the MGS post charge. Unfortunately it says the file is too big, but the readings I did verify. I am using the new Denso comp instead of the OE Delphi but I am guessing whether ...

John, Bringing an end to this thread... The problem is solved. I didn't understand the VD compressor concept previously, and upon following your recommendations, everything seems to be working upon my most recent recharge. I also did not realize the length of time this process takes. In all, it prob...

John, Thanks very much for this info. Next recharge attempt forthcoming... I started reading about the VD compressors on the MACS website. It was enlightening, realizing that even when the clutch is turning it is operating at a smaller capacity and increases accordingly. The old OT tube was not bad,...

John, Yes, hi side gained around 50 psi, max 60 or so, never exceeding the highest readings of the lo side. Cabin air never seemed to change temp throughout. I should note, the new compressor is a Denso 4719185; the first 2 attempts were Delphi's. The sticker was worn off the original Delphi so unsu...

A note that came to mind: I am seeing oil around the compressor seals. I remember putting several drops on them prior to my installs, but the amount I am seeing looks like there is too much there than what may have come off of them as I tightened the suction/disch lines down. That said, I have reuse...

John, Thank you for all this information. I'll change many things for the next attempt... I am sure that the adapters were connected and turned CW. I wondered about a leak, but thought certainly that a satisfactory vac test ruled it out. Your statement on that intrigues me. I thought of the condense...

John, Thank you for your response. I had the handwheel closed to hi side during charging, only was open for vacuum and leak tests. I would like to know more about liquid charging to the hi side. I have heard this can be a bad thing? Yes, air was bled from the schrader on the MGS, not the can directl...

Hello, New to the forum. Seeking AC wisdom...getting headaches from this situation below. Sorry in advance for this long ignorant post... 98 Buick Park Ave 3.8L NA -AC system worked for previous owner, circa 1 year ago, but he would only have cold air for 2 weeks after adding freon. Diagnosed at sho...
