Question about 1992 Lexus Sc 400
On a 92 sc400 the low side is right on the top left of the compressor (closest to the left side of car)with a cap on it like a tire cap pointing forward thats the low end suction side to put freon in , the one up high is the high side do not use it to put freon in use the low suction line and the motor must be running with ac on high coldest setting and only put 1 R12 can in not over 14oz anything beyond use gauge or go to shop , the reason thats safe is the range from low to high is large maximum is 2.5.lbs 16oz is a pound 1 14oz can usually perfect 2 is still medium safe without gauge, but always know what your doing! and be safe. I rate it 1 step above putting air in your tire.
