A/C Service Tips and Precautions
The air conditioner system uses HFC-'134a (R-134a) refrigerant and polyalkyleneglycol {PAG) refrigerant oil*, which are not
compatible with CFC-12 (R-12) refrigerant and mineral oil. Do not use R-12 refrigerant or mineral oil in this system, and do
not attempt to use R-12 servicing equipmenu damage to the air conditioner system or your servicing equipment will
resutr.
*KEIHIN SP-10:
. P/N 38897 - Pl3 - A01AH: 120 m{ (4 fl.oz, il.2 lmp.oz)
. P/N 38899 - Pl3 - A01: 40 mf 11113tl.oz,1.4 lmp.oz)
Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove R-134a
from the air conditioner system,
CAUTION: Exposure to air conditioner refrigerant and lubricant vapor or misl can irritats eyes, nose and throat. Avoid
breathing the air conditioner refrigerant and lubricant vapor or mist,
lf accidental system discharge occurs, ventilate work area before resuming service.
R 134a service equipment or vehicle air conditioner systems should not be pressure tested or leak tested with compressed
air.
E@ Some mixtures of air and R-13,1a have been shown to be combustible at elevat€d pressures and can result
in fire or explosion causing iniury or property damage. Never use complessed air to pressure test R-l3,[a service equip-
ment or vehicle air conditioner systems.
Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.
1. Always disconnect the negative cable from the battery whenever replacing air conditioning parts.
2. Keep moisture and dust out of the system. When disconnecting any lines, plug or cap the fittings immediately; don't
remove the caps or plugs until just before you reconnect each line.
3. Before connecting any hose or line. apply a few drops of refrigerant oilto the O-ring,
4. When tightening or loosening a fitting, use a second wrench to support the matching fitting.
5. When discharging the system, use a R l34a refrigerant recovery/recycling/charging station; don't release refrigerant
into the atmosphere.
6. Add refrigerant oil after replacing the following parts.
Note these items when handling refrigerant oil:
o To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refriger-
ant oils.
. lmmediately after using the oil, replace the cap on the container, and seal it to avoid moisture absorption.
. Do not spill the refrigerant oil on the vehicle; it may damage the painu if the refrigerant oil contacts the paint, wash
it off immediately.

Performance Test
The performance test will helD determine if the air con-
ditioner system is operating within specifications.
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner svstem.
CAUTION: Exposure to air condiiioner r€trigerant and
lubricant vapor or mist can irritate €yes, nose and
throat. Avoid bre8thing the air conditioner retrige.ant
and lubricant vapor or mist,
lf accidental system discharge occurs. ventilate work
area before resuming service.
R-134a service equipment o. vehicle air conditioner sys-
tems should not be pressure tested or leak tested with
comDressed air.
@ some mixtur€s ol air and R-134a have becn
shown to be combuslible at olsvated pressures and can
result in lire or explosion causing iniury or property
damage. Never use compressed air to prgssure test R-
13i[a service equipment or vehicle air conditioner sys.
tems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.
Recovory/Recycling/charging station
LOW.PRESSURESIDE
1.Connect a R-134a refrigerant recover/recycling/
charging station to the vehicle, as shown. following
the equipment manufacturer's instructions,
Insen a thermometer in the center air vent. Determine
the relative humidity and air temperature.
Test conditions:
. Avoid direct sunlight.
o Open hood.
. open front doors.
. Set the temperature control dial on MAX COOL,
the mode control dial on VENT and the reci.cula-
tion control switch on RECIRCULATE.
. Turn the A,/C switch on and the fan switch on
MAX.
. Run the engine at 1,500 rpm.
. No driver or passengers in vehicle
After running the air conditioning for 10 minutes
under the above test conditions, read the deliverv
temperature from the thermometer in the dash vent
and the high and low system pressure from the Ay'Cgauges.

Recovery
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner system.
CAUTION: Exposure to air conditioner refrigerant and
lubricant vapor or mist can irritate eyes, nose and
throat. Avoid brqathing the air conditioner retrigerant
and lubricant vapor or mist.
lf accidental system discharge occurs, ventilate work area
before resuming service.
R-134a service equipment or vehicle air conditioner sys-
tems should not be pressure tested or leak tested with
compressed arr.
@@ some mixtures of air and R-134a have been
shown to be combustible at elevated plessures and can
result in fire or explosion causing iniury or property dam-
age. Never use compressed air to pressure tect R-134a
service equipment or vehicle air conditioner systems.
Additional health and safety intormation may be obtained
from the refrigerant and lubricant manufacturers.
'1. Connect a R-134a refrigerant recove rylrecycling/
charging station to the vehicle, as shown, following
the equipment manufacturer's instructions
2. Measure the amount of refrigerant oil removed trom

tems should not be pressure tested or leak tested with
compressed arr.
!@ some mixturos of air and R-1348 have
been shown to be combustible at olovatod pres3uras
and can result in fire or explosion causing iniury or
property damage. Never use comprelised air to pressure
test R-13ila service equipment or vehicle air conditioner
systems.

1.Connect a R-134a refrigerant recove rylrecycling/
charging station to the vehicle, as shown in the pre-
vious column, following the equipment manufactur-
er's instructions.
Open the high-pressure valve to charge the system
to the specified capacity, then close the supply
valve, and remove the charging system couplers.
Select the appropriate unit of measure for your
charging station.
Refrigerant capacity: 700 to 750 g
0.70 to 0.75 kg
1.5 to 1.6 lbs.
21.7 to 26.5 oz.
Check the system for leaks using a R-134a refriger-
ant leak detector with an accuracy of 14 g (0.5 ozl
per year or better.
lf you find leaks that require the system to be opened
(to repair or replace hoses, fittings, etc.), recover the
system according to the Recovery Procedure on page
22-59.
After checking and repairing leaks, the system must
be evacuated (see System Evacuation on page 22-601.
