Is anyone here familiar with high and low side pressures I should look for on a 98 V70 with r134a refrigerant? The average daytime temp around here is about 80F this time of year. Also, I found the low side port, but where the heck is the high side port located? Mine was not cooling well and the compressor was cycling, so I put just enough charge in to keep the compressor on. I don't want to continue adding refrigerant until I can measure the disharge pressure. This is the first time refrigerant has been added to the system, so I suspect the low charge was normal due to age.
thanks,
kcarl
