NOTE: When compressing the damper spring, use a
commercially available strut spring compressor
(Branick MST-580A or Model 7200, or equivalent)
according to the manufacturer’s instructions.
1. Remove the cap (A) from the top of the damper.
2. Compress the damper spring, then remove the self- locking nut (A) using the strut nut adapter, a ratchet
or breaker bar while holding the damper shaft with
a hex wrench (B). Do not compress the spring more
than necessary to remove the nut.
3. Release the pressure from the strut spring compressor, then disassemble the damper as
shown in the Exploded View. 1. Reassemble the damper mounting base and the
self-locking nut.
2. Compress the damper assembly by hand, and check for smooth operation through a full stroke,
both compression and extension. The damper
should extend smoothly and constantly when
compression is released. If it does not, the gas is
leaking, and the damper should be replaced.
3. Check for oil leaks, abnormal noises, or binding during these tests.

21-621-6 Climate Control
A/C Service Tips and Precautions A/C System Inspection
A
 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
or 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 c onditioning
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. Before troubleshooting any problem with the air
conditioning system, do the following:
1. With the ignition switch in LOCK (0), inspect the A/C components, the pressure lines, and the hoses for
stains that may indicate a refrigerant or a
compressor oil leak.
2. Check the A/C condenser (A) for material clogging the fins or for damage to the fins:
 Carefully clean any material from the A/C condenser fins with water and detergent. If
deeper cleaning is required, clean the fins with
Honda brite cleaner (P/N 08732-0020B).
 Be sure to dry the A/C condenser completely.
 Refer to the Refrigerant Leak Check (see page 21-93) to confirm leaks if there is visible damage
to the A/C condenser.
Check for stains.

3. Inspect the drive belt (see page 4-30).
4. Make sure no material is blocking the air flow to the
A/C condenser.
5. Check the dust and pollen filter. Replace it if it is clogged (see page 21-75).
6. Check for kinks or sharp bends in the A/C lines and hoses, which can greatly reduce system
performance. Replace A/C lines and hoses if they
are kinked or damaged (see page 21-8).
7. Start the engine, turn the air conditioning system on, and allow it to run for a few minutes and reach
stable operation.
 Check that the A/C operates at each position of the blower fan switch (except OFF). If the A/C
does not operate, refer to the symptom
troubleshooting.
 Check that the A/C compressor clutch (A) is engaged. The pressure plate should be rotating
at the same speed as the pulley. If the pressure
plate does not engage, refer to the symptom
troubleshooting.
 Check that the A/C condenser fan (B) and radiator fan (C) operate when the A/C compressor clutch
is engaged. If either fan fails to operate when the
A/C compressor clutch is engaged, refer to the
symptom troubleshooting.
 Check that the engine idle speed is correctly maintained when the A/C is switched on and off
and the A/C compressor clutch is engaged and
disengaged. Recommended PAG oil: SP-10
P/N 38897-P13-A01AH: 120 mL (4 fl·oz)
It is important to have the correct amount of refrigerant
oil in the A/C system to ensure proper lubrication of the
compressor. Too little oil damages the compressor; too
much oil reduces the cooling capacity of the system,
and can produce high vent temperatures.
 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.
Add the recommended refrigerant oil in the amount
listed if you replace any of the following parts: ........
.............. ............ ........

A/C condenser .50 mL (1 2/3 fl·oz)

Leakage repair .25 mL (5/6 fl·oz)
A/C compressor .Since the oil separator is
equipped inside the compressor
for this vehicle, oil drainage is
unnecessary at the time of
compressor replacement.
