Servicing R134A Retrofitted Vehicle Systems
Servicing R134a Retrofitted Vehicle SystemsVehicles retrofitted from R12 to R134a use conversion fittings on the high and low side R12 service ports which allow connection to your R134a recovery equipment. When servicing a previously retrofitted vehicle, there is concern that if all of the R12 was not removed during the retrofit procedure, your R134a equipment and recovery tank will become contaminated.
