designed to use R-134a. System failure will
occur.
Both of the service ports to charge the air condi-
tioning system are located on the hoses (Fig. 4). New
design of service ports have been used to ensure that
the system is not accidentally filled with the wrong
refrigerant (R-12).

When servicing a system, it is required that an air
conditioning charging recovery/recycling machine be
used (Fig. 5). Contact an automotive service equip-
ment supplier for proper equipment. Refer to the
operating instructions provided with the equipment
for proper operation.
A manifold gauge set (Fig. 6) must also be used in
conjunction with the charging and/or recovery/recy-
cling device. Only use gauges that have not been
used for R-12. The service hoses on the gauge set
should have manual (turn wheel) or automatic back
flow valves at the service port connector ends. This
will prevent refrigerant R-134a from being released
into the atmosphere.
R-134a refrigerant requires a special type of com-
pressor oil. When adding oil, make sure that it is
designed to be used in a R-134a system. Refer to the
label under the hood for proper oil and refrigerant
charge levels (Fig. 7).
Due to the different characteristics of R-134a it
requires all new service procedures.
