Re: 134 A/C
I`ve converted no less than 25 cars to R-134. Its better to vacuum the system but not mandatory. Add one can of 134 to keep the compressor energized, then add the correct amount of oil. Now add 134 until the low side gauge reads 40-45 lbs. The compressor or dryer does not have to be changed.
