Can you determine refrigerant levels based on pressures alone? In other words if my readings are whatever normal would be, let's say 35/250, is that enough to know I have the proper amount of refrigerant? How accurate would that be considered? Is it accurate to say 4 ounces, or dead on accurate?
Is the only true way to get an accurate idea of refrigerant level an evacuation and recharge with weighed refrigerant?
Just a general question. TIA!
You must weigh "out" the charge to know refrig amount
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
