Need to know correct operating pressures on the high and low side with freon 12 and 134a, for 93 chev 1500 extencab 4x4. In process of replacing compressor, dryer, and orfice with all NEW A/C delco parts. If I change to 134a will be changing the oil to PAG 150. Vehicle is in south florida temp 90's humity 90%. What do you recommend as far as change over. If I do change to 134a will I be looking at other problems ie hoses due toincrease pressures?
Thank YOU
