Looking for confirmation. GM A6 compressor using R-134 takes PAG 150, 10.5 oz? Is that total system capacity? 69 Camaro, factory system.
Also, is it filled through the suction port?

Does it matter where in the liquid line the dries is located?
I am putting a system in a car with very limited space. It is not at all possible to mount it on or, very near the condenser. The evaporator/expansion valve/blower unit is in the trunk.
I am considering a horizontal flow drier in the ...

Going to refund the customer on the Parts & Labor to replace a perfectly good condenser unnecessarily?
.
Refund? The job was still a work in progress when condenser replaces so, the customer had not paid anything yet. However, not sure I would call a 22 year old condenser perfectly good. No, not ...

Anyway, good find.

Yeah, not it was not the epitome of efficiency now was it. I believe the boss did the paper test. I asked the tech many times about the fans....

Are any of you using thermocoupeles for diagnosis? I am considering buying the below tool but, looking for opinions before shelling out $250.

So, after repeatedly telling me the fans were working correctly, the boss and tech found the condenser fan to be running BACKWARD!!S Aftermarket fan, wired backwards, pushing hot air from the radiator instead of pulling hot air from the condenser! When this first started, I asked him if he was sure ...

Condenser airflow issue.

Spray the condenser with water & watch the pressure drop like a rock.

Fan(s) not working / worn out & not reaching full speed etc.
Fans working correctly. Does not make sense. Cannot find a restriction in the high side. No cold spots on the condenser. When/if we figure ...

Update. Condenser has been replaced. Still excessive high pressure. (450 PSI) So, all major components have been replaced except evaporator. New compressor, condenser, drier,and expansion valve. Refrigerant charge level is correct and oil amount verified. It acts like a restriction in the high side ...

[quote="Cusser"]Is that a serpentine type of condenser? Those are more likely amenable to reverse flushing than the parallel flow condensers, where solvent can bypass many passages. That's why parallel condensers are most often just replaced with new.[/quote
I am not sure what type of condenser it ...

Trying to help out a fellow tech. in the shop. !996 VW Eurovan came into the shop with no cooling. Single A/C - front only. Technician replaced compressor, drier and espansion valve, flushed out condenser and evaporator, evacuated system and charged with correct amount of correct refrigerant. When ...
