Heating/Air Conditioning
A/C Service Tips and Precautions
• Compressed air mixed with the R-134a forms a
combustible vapor.
• The vapor can burn or explode causing serious
injury.
• Never use compressed air to pressure test
R-134a service equipment or vehicle air
conditioning systems.
• Air conditioning refrigerant or lubricant vapor
can irritate your eyes, nose, or throat.
• Be careful when connecting service equipment.
• Do not breathe refrigerant or vapor.
The air conditioning 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 equipment; damage to the air conditioning
system or your servicing equipment will result.
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 conditioning system.
If accidental system discharge occurs, ventilate the
work area before resuming service.
R-134a service equipment or vehicle air conditioning
systems should not be pressure tested or leak tested
with compressed air.
Additional health and safety information may be
obtained from the refrigerant and lubricant
manufacturers.
• Always disconnect the negative cable from the
battery whenever replacing air conditioning parts.
• Keep moisture and dirt 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.
• Before connecting any hose or line, apply a few drops
of refrigerant oil to the O-ring.
• When tightening or loosening a fitting, use a second
wrench to support the matching fitting.
• When discharging the system, use an R-134a
refrigerant recovery/recycling/charging station; don't
release refrigerant into the atmosphere.

A/C Refrigerant Oil Replacement
Recommended PAG oil: DENSO ND-OIL 8
• P/N 38897-PR7-A01AH: 120 mL (4 fl·oz)
• P/N 38899-PR7-A01: 40 mL (1 1/3 fl·oz)
Add the recommended refrigerant oil in the amount
listed if you replace any of the following parts.
• To avoid contamination, do not return the oil to the
container once dispensed, and never mix it with other
refrigerant oils.
• Immediately after using the oil, reinstall 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 paint; if it gets on the paint, wash it off
immediately.
A/C condenser
(including Dryer
Desiccant) ............... ............... .35 mL (1 1/5 fl·oz)
Evaporator .............. .............. .35 mL (1 1/5 fl·oz)
Line or hose ............ ............ .10 mL (1/3 fl·oz)
Leakage repair ........ ........ .25 mL (5/6 fl·oz)
A/C compressor ...... ...... .For A/C compressor replacement,
subtract the volume of oil drained
from the removed A/C
compressor from 82 mL
(2 7/9 fl·oz), and drain the
calculated volume of oil from the
new A/C compressor: 82 mL
(2 7/9 fl·oz)
A/C compressor = Volume to
drain from new A/C compressor.
NOTE: Even if no oil is drained
from the removed A/C
compressor, don't drain more
than 50 mL (1 2/3 fl·oz) from the
new A/C compressor.
