Around 35 (30-40) is recommended and, when I first started up the car and connected my gauge it was hovering in the 29-31 range. I have a charge hose with a built-in gauge that can be connected to a recharge can. I was using that to monitor the pressure. Unfortunately, as I mentioned, it only checks low-side pressure, which is why I was reluctant to play around too much. | |

| Aug 13, 2015 at 11:42 | comment | added | John Chrysostom | I think my next step is going to be to go to a mechanic to get high side pressure checked, and to verify that there is no debris in the system. I'll check back. | |

Pressure was on the low end of the recommended range, so I tried adding a bit of coolant. Interestingly, the system didn't seem to want to accept coolant for some reason - it all came leaking out of the hose. I've never experienced this when recharging A/C before, and it's possible that my charging hose/gauge was faulty (they're really old). I was reluctant to try too hard to get it to accept coolant, as I understand you can kill your compressor if you add too much without monitoring the high side pressure. | |

| Aug 12, 2015 at 12:46 | comment | added | John Chrysostom | This makes a ton of sense. Thank you. I'll check the high-side pressure tonight and, if that looks good, I'll take it to somebody to have the low-side looked at. | |
