Replacing the A/C system from R12 to 134a?
Need to know how much oil? What kind of oil? How much 134a refrigerant? What should the pressure be on low and high side with a temperature of 85 degrees?
http://www.ehow.com/how_7160949_retrofitting-r12-r134-toyota.html ..... Please! do not release the R12 Freon in to the air when you do this. It is illegal for one thing... needs to be captured and disposed of properly. For all our sake. Thank You.
