Femove the bolts, and disconnect the receiver line
and the suction line from the evaporator.
NOTE: Plug or cap the lines immediately after dis-
connecting to avoid moisture and dust contamina-

8. Install in the reverse order of removal. and:
it you're installing a new evaporator, add refrig-
erant oil (ND-OIL 8: P/N 38899 - PR7 - A01) (see
page 22-2'll.
replace the O-rings with new ones at each fitting.
and apply a thin coat of refrigerant oil (ND-OlL 8:
P/N 38899 - PR7 - A01l before installing them.
NOTE: Be sure to use the right o-rings for HFC-
134a {R-134a} to avoid leakage.
apply sealant to the grommets.
make sure that there is no air leakage.
charge the system (see page 22-39) and test its
performance (see page 22-241.

Tips and Precautions
Before Troubloshooting
a Check applicable fuses in the appropriate fuse/relay
DOX.
a Check the battery for damage, state of charge, and
clean and tight connections.a Check the alternator belt tension.
CAUTION:
a Do not quick-charg€ a battery unless the batteryground cabla has be€n disconnoctsd. oth€rwisoyou will damage the alternator diodss.a Do not att6mpt to crank the engine with the bat-tery ground cable loosely connectsd or you will se-vorsly damag€ tho widng.
a The original radio has a codod thatt plotection ci.-cuit. Be sul€ to got tho customor's code numbet
before- disconnecting th€ battery.- lomoving tho No. 32 (7.5 Al tuso f.om the
under-hood tuse/lelay box.- removing tho radio.
Aflor s€lvic€. reconn€ct powet to tho radio and
turn it on. Whon the word "CODE" is displayed,
€nt€l the customer'E s-digit codo to .astore ladio
operation.
Handling Connectors
a Make sure the connectors are clean and have no loose
wire terminals.
a Make sure multiple cavity connectots are packed withgrease (except watertight connectors).a All connectors have push-down release type locks.
LOCKII{G TAA
LOCKING TAB
a Some connectors have a clio on their side used to at-
tach them to a mount bracket on the body or on
another component. This clip has a pull type lock.
a Some mounted connectors cannot be disconnected
unless you first release the lock and remove the con-
nector from its bracket.

a Never try to disconnect connectors by pulling on thei.
wires; pull on the connector halves instead.
a Always reinstall plastic covers.
Belore connecting connectors, make sure the lermi-
nals are in Dlace and not bent.
a Check tor loose retainer and rubber seals.
RETAINER
a The backs of some connectors are oacked with
grease. Add grease if needed. It the grease is contami-
nated, reDlace it.

Handling Wir€s and Hamorao8
a Secure wires and wile harnesses to the frame with
their respective wire ties at the designated locations'
a Remove clips carefully; don't damage their locks'
Stip pliers under the clip base and through the hole at an
angle, then squeeze the expansion tabs to release the
clio.
SI'IAP-ANG PLIERS
a After installing harness clips, make su.€ the hatness
doesn't interfe.e with any moving parts.
a Keeo wire hatnesses away from exhaust pipes and
other hot parts, ftom sharp edges of brackets and
holes, and from exposed screws and bolts.

Tosting and Ropails
a Do not us€ wires or harness€s with broken insulation.
Replace them or repair them by wrapping th€ break
with electrical tape.
a After installing pans, make sure that no wir€s are
Dinched undsr them.
a When using electrical test €quipment, follow the
manufacturer's instructiona and those dsscribed in
this manual,
a It possible, insert the probe of the toster from the wire
side {except waterproof connector).
a Seat grommets in theil grooves properly.
a Use a probe with a tapered tip.
