2006 Volvo 780 D12. My air conditioner is not cooling as well as previously (probably small leak). I've not had a problem prior to this. I have access to hose gauge set for recharging if necessary. I use R-134a. My question is in looking at the high/low side pressures and ambient temperature is the chart specific for my truck or can a standard generic R-134a chart be used like this one to gauge whether I need to add coolant?
