R-134a A/C Pressure Chart by Ambient Temperature - Low & High Side PSI/kPa

This document is an R-134a temperature/pressure reference chart (bilingual English/Spanish, titled 'Tabla de Temperaturas y Lecturas') from a 'DIY A/C Recharge' source, with header links labeled 'HOW TO' and 'SERVICE PORT FINDER'. It lists expected low-pressure and high-pressure gauge readings for automotive air conditioning systems using R-134a refrigerant across ambient temperatures from 65°F (18°C) to 110°F (43°C) in 5-degree increments. Each row shows the ambient temperature, the low-pressure (low-side service port) reading range in both psi and kPa, and the high-pressure (high-side service port) reading range in psi and kPa. For example, at 75°F (24°C) the low side should read 35-40 psi (241-310 kPa) and the high side 150-170 psi (1034-1172 kPa); at 95°F (35°C) the low side should read 50-55 psi (345-379 kPa) and the high side 275-300 psi (1896-2068 kPa). A footnote clarifies that ambient temperature means the outside atmospheric temperature. The chart is a generic diagnostic aid for checking A/C system charge and performance with a manifold gauge set; it is not vehicle-specific, though it was filed with a 1995 Ford Bronco.
