Need to know how to add freon to 1992 Chev. Lumina Euro. Have gauges and can purchase freon, but don’t know where to attach gauges.
Am ready to sell car. but don’t want to do so if ac does not work. I don’t want to put more money into it, if compressor is problem.
Please help this dummy.
If you don’t know where to connect the gauges, then this is not something you want to mess around with as it can cause more damage to the AC system. Here’s an example. Do you know what conditions the engine must be operating at when recharging the system? And do you know what it means to make ambient temperature corrections when charging an AC system? If not, you’ll save yourself a whole lot of headaches and money taking it to someone who knows what they’re doing.

I agree with Tester. It can also be very dangerous to your health.
Inadvertently open the high side of the gauges with slightly excessive pressure involved and the can of refrigerant can explode in your hands.
This can lead to frostbitten fingers in a few seconds and blindness in half a second.
The car is 17 years old and if the system is empty it’s quite likely that all you would accomplish is a recharge today followed by an empty system the next day due to multiple refrigerant leaks.
Hint, if it needs freon, it has a leak, after all the A/C does not consume the stuff. If it has gone down too far it will need more than just more freon, it will need a new dryer etc.
Have it evaluated and repaired by a good shop. It will save you money in the long run.
