Found some info so I'll answer my own question for the next person who stumbles across this...
In my brother's car, it holds 6.5 oz of oil. Put 3 oz of oil into it and hold it so that the pully/clutch asm is facing towards the ground for about 3 minutes. Then the other 3.5 oz I injected via the AC service machine. I used a pin wrench to turn the compressor 10 turns.
But now there is another problem... so another post..... |
