What should the charge level be when converting from R12 to R134a?
Fortunately, we have an R12 to R134a conversion chart and formula to retrofit appropriately. A charge level between 75% and 85% is recommended when converting from R12 to R134a refrigerant. If no conversion information is provided, there is an easy formula to calculate the difference in charge level.
How to convert an R12 compressor to a R134a?
R12 to R134a Conversion steps. The first step is first to make sure that the AC system is empty. Discharge and make sure to recycle it properly. Make sure your AC compressor is in good shape, otherwise replace it. Flush your current system entirely of R12 without leaving any traces of the R12 in it.
How to retrofit R12 system to R134a?
If your vehicle has a Ford FX-15 compressor, replace with an FS-10 compressor. 3) R134a retrofit kit with R-134a port adapters, oi, port caps and retrofit label
When did cars start using R12 instead of R134a?
Many organizations believe that R134A contributes to global warming. Vehicles manufactured before 1994 used R12 for air conditioning. Vehicles older than 1994 started using R134A instead of R12. So what if you have a car that was made in 1994 or even earlier?

Which is better for retrofit R12 or R134A?
You can use the R134a retrofit capacity chart for this purpose. Generally, the new amount is 75-85% of the quantity advised by the manufacturer. R134a has a lower tolerance for mischarging, so you will face worse performance even if you overcharge as compared to the R12.
