QuestionWHEN I REPLACED A SEIZED COMPRESSOR THERE ISN'T ANY OIL COMMING OUT FROM THE OLD ONE, I USED SHOP AIR TO BLOWED OUT THE LINES,EVAPORATORS AND CONDENSOR. CHANGED NEW O-RINGS, ACCUMULATOR, ORFICE TUBES AND ADDED 7 OZ OF OIL IN. DID THE STANDARD PROCEDURES TO VAC. AND CHARGED, THEN STOP A/C REMOVED GAUGE. ON THE HIGH SIDE PORT WHILE REMOVING GAUGE, THE VALVE CORE SMALL TINY RING WAS CRACKED AND LOST ALL THE FREON (R134A),
THOUGH I LOST ALL THE OIL, SO I RE-VAC. AND CHARGE AGAIN WITH 6OZ OF OIL. NOW A/C BLOWING NOT AS COLD AS I EXPECTED. OUT SIDE TEMP 90 DEG.AND HUMMID. AT 85 PERCENT(SOUTH EAST TEXAS), ENGINE AT 1000 RPM, LOW PORT 60PSI, HIGH PORT 270 PSI,FRONT VENT BLOWS AT 70 DEG., REAR BLOWS AT 65 DEG., REV. THE ENGINE UP TO 1700-2000 RPM THE LOW PORT 80 PSI, HIGH PORT 310 PSI, FRONT BLOWS 65 DEG. REAR BLOWS 60 DEG., USE THE GARDEN HOSE MIST SPRAY ON CONDENSOR THE LOW PORT DROPPED TO 45 PSI, HIGH PORT DROPPED TO 170 PSI,
WHAT DO YOU THINK ABOUT THE READING ABOVE?
IF NOT WHAT COULD BE WRONG?
HOW CAN I CORRECT IT? CAN THE READING ABOVE DAMAGE MY NEW COMPRESSOR?
NOTE: THE COMPRESSOR IS BRAND NEW OE.
THANK YOU FOR YOUR TIME
AnswerWITH HIGH REAGINGS ON BOTH SIDES IS A INDICATION OF AIR IN THE SYSTEM.LOW SIDE 20-30PSI / HIGH SIDE- 180 210PSI @1000RPM. BE SURE THE RADIATOR FANS ARE BOTH ON.RECHECK YOUR HOSES AND VACCUM PUMP ATTACHMENTS. EVCATE AND RECHARGE A/C AGAIN
GOOD LUCK
