Let me give the scenario when I took the readings. Side of a building in direct sunlight, no wind, cabin temp reading about 90+ but over the engine it feels way hotter.
Based on my picture and ambient temperature 90 Fahrenheit is my low side 42 using the black number or is it 48 in the blue scale that looks to be marked at the beginning of the blue "r134a"?
have the same problem?
