The industry has no tests or published information to establish cooling performance, reliability, compatibility, or an assessment of chemical damage to a system's lubricant seals and hoses. And the EPA has approved the new 1234yf refrigerant only for new vehicles with systems designed ...An R-12 system converted to R-134a will normally loose some refrigerant over time. The R-12 systems didn't use barrier hoses . The R-134a molecule is much smaller than the R-12 and it finds its way out of smaller leak paths. So even if the system is fairly well sealed, you may have to add refrigerant every year or so.We'll show you both a quick and dirty way, and a precise, more complicated formula for converting a Celsius temperature to Fahrenheit (and vice versa).

I plan to install one whenever i get around to doing my ac, i have everything else. If you want to do it by the 'book',
