I think this has been discussed, but one more time- can I convert my R12 unit to R134? If so, how and what are the down sides? Does the oil need to be drained and replaced before converting? Any help will be appreciated. |

Put the blue (compound gauge) on the low side. Put the red (pressure gauge) on the high. Some hoses are color coded some are not. just put the hosew directly under each gauge as described above. Purge freon through manifold before charging so as to not force in air. Pressures vary by temperature.I think the 82 has a sight glass up front?? If so charge with compressor on till no bubbles. If not a litle more diffucult unless you evacuate system and charge from empty. Then weigh in 2.2 .lbs. Recommend getting a pro to do this job if unfamiliar. Suppose to have EPA license to do legally anyway. |

If you are using R12 and R12 gages you can use the 2 attachments to do a refill. Make sure that the high pressure hose (red) is on the high pressure side of the compressor and the low pressure (blue) hose is on the suction side of the compressor. Check the pressures to make sure they are in spec. and if not charge through the low pressure side. I assume that you had checked for leaks and vacuum down the system. Good luck. |

Don't the gauges have colored areas for different types of refrigerant such as R12 and R22? And the colored areas represent which side of the compressor you're on. Just make sure you don't get a hose full of ordinary air pushed into your system. |

Can anyone tell me if you can charge the A/C on a 1982 model with the two gauge, two hose system? And what pressure should it read? Anything to watch out for (other than too much pressure)? |
