AIRCONDITIONING REPAIRS, WHERE DOES THE NEW 134A ORFICE GO?

[LASVEGASCRUISE]

1989 VOLVO 740GL

I RECHARGED MY AC LAST SUMMER, EVAC AND RECHARGE RETROFIT FIT KIT, ESTER OIL AND 134A...THEN THE COMPRESSOR LOCKED UP. I COULDN'T UNDERSTAND WHERE ALL THE BLUE SMOKE WAS COMING FROM WHEN IT HAPPENED....IT WAS MY CAR!!!!

i BOUGHT A NEW COMPRESSOR WHICH IS NOW 134A, RECEIVER DRYER, ORING KIT, RETRO KIT WITH 134A ORFICE WITH ESTER OIL.

I PLAN ON INSTALLING THE COMPONENTS MYSELF THEN TAKING TO A QUALIFIED AC SHOP FOR AC EVAC AND CHARGE. THE COMPRESSOR AND DRYER ARE OUT OF THE VEHICLE AS OF YESTERDAY BUT I HAVE QUESTIONS.

1. FROM READING OTHER POST REGARDING AC ON THIS THREAD, I HAVE DECIDED TO REPLACE THE AC LINES (RUBBER). ONE LINE THAT GOES FROM THE CONDENSOR TO THE DRYER HAS A MUFFLER ON IT AND IT SEEMS A NEW HOSE IS NO LONGER AVAILABLE WITH THE MUFFLER.

DOES THIS MATTER.

2. I HAVE A NEW 134A ORFICE BUT DO NOT KNOW WHERE IT GOES

3. I PLAN ON TAKING ALL LINES APART FROM THE REMAING FITTINGS AND FLUSHING ALL INDIVIDUAL COMPONENTS )EVAP/CONDENSOR/REMAINING LINES NOT REPLACED)WITH BRAKE CLEAN THE WITH AIR...IS THIS ADEQUATE?

4. WHERE THE DRYER MOUNTS THERE IS A LARE BLACK CAP ON THE BRACKET...APPROX 2" TALL AND CAN BE REOMOVED WITH A 22MM WRENCH. (A) WHAT IS THIS (ORFICE)? (B) I REMOVED IT AND OIL SOME DYE CAME OUT (THE SYSTEM WAS EVACUATED ALREADY)

5. IF AC ESTER OIL IS INSTALLED DIRECTLY INTO THE COMPRESSOR UPON INSTALLATION WILL THIS OIL BE VACUMED OUT WHEN THE AC EVAC/RECHARGE IS PERFORMED. IT SEEMS THAT THE SUCTION SIDE OF THE AC SYSTEM (LOW SIDE) IS ON THE COMPRESSOR.

6. ANY OTHER SUGGESTIONS WOULD BE HELPFUL.



I WORK IN A SERVICE DEPARTMENT SO THE TECHS HAVE NO CLUE WHEN IT COMES TO A VOLVO.

THANKS
