Unlock the Secrets of AC Performance A Comprehensive Automotive AC Pressure Guide

... AC pressures should operate around for a vehicle using R134a refrigerant. I also talk about my recommendations for finding and fixing leaks ... Accoding to those charts, if outside temp is 95F, then low side pressure ... More to the point, does the AC cool the car when it is 95? If so, go ... Thanks but thats not vehicle specific but just a general guideline. ... AC was blowing cold air, I would think that would be good enough. If ... Anyone know what the correct low/high side air conditioning readings should be for a 190e with R12? ... Auto AC systems are inherently leaky to ... I'm far from an expert on car systems. Assuming this is a 134a system. You can look up online approximate "normal" pressures. Why did you choose ... Before the vehicle is started, the static system pressure can be read. ... The PCM gets inputs from the HVAC switch, and from the AC pressure ... You will have to get the system to the above pressure chart, while the car and AC compressor is running. I believe the total capacity for C7 ... Low side pressure should sit right at 30psi at all times the compressor is on, within a couple psi is OK. High side pressure will change ... The R134a pressure chart delineates the relationship between pressure and temperature within an air conditioning system, utilizing R134a refrigerant. This chart ... Measure the ambient temperature and compare the reading with the pressure-temperature chart of R134a below: In my case, the ambient temperature ...
