wikiHow Contributor When the process is charging and also the engine is just earlier mentioned idle, you are going to ordinarily need a low stress looking at about 30 psi (two hundred kPa). The large tension reading fluctuates tremendously with engine pace, air humidity, and also other components, but a very tough guideline is "significant pressure psi = 2 x temperature in Fahrenheit." This is much more accurate for R12 refrigerant, even though R134a refrigerant tends to be a good bit greater.
Use the ambient air stress chart within the gauge to determine pressure. Examine the gauge Display screen whilst taking the ambient temperature under consideration to determine what amount the refrigerant is now at.
