Replacement
1.Remove the glove box (see section 20).
Remove the glove box frame {see page 22-4A).
Release the wire harness from the clamps on the
evaporator. Remove the filter lid, then pull out the
,VC filter assembly from the evaporator housing.
A/C FILTER ASSEMELY
Remove the A/C filter from the filter housing.
Replace the Ay'C filter according to the maintenance
schedule in the owner's manual.
Install in the reverse order of removal. Make sure
that there is no air leakage.

1. Disconnect the negative cable from the battery.
2. From under the hood, open the cable clamp, then dis-
connect the heater valve cable from the heater valve
arm. Turn the heater valve arm to the fullv ooened
oosition as shown.
When the engine is cool, drain the engine coolant
from the radiator (see section 10).
@ Do not remove the rldiator cap when
the engine is hot; the engine coolant is under pres-
sure and could sevo.ely scald you.

Engine coolant will run out when the hoses are dis-
connected; drain in into a clean drip pan.
CAUTION: Engino coolant will damage p8int. Ouickly
rinse any spill€d engine coolant Itom painted sur-
faces.

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.
