these items:
. Apply sealant to the grommets
. Do not interchange the inlet and outlet hoses.
Make sure that the hose clamps are secure.
. Loosen the bleed bolt on the engine and refill the
radiator and coolant reservoir with the proper
engine coolant minure (see section 10).
Tighten the bleed bolt when all the trapped air
has escaped and engine coolant begins to flow
from it (see section 10).
. Connect all cables and make sure they are prop-
erly adjusted (see page 2'l-271.

clean the pulley and compressor sliding surfaceswith non-petroleum solvent.
check the pulley bearings for excessive play.
make sure the snap rings are in the groove prop-
efly.
apply locking agent to the threads of the center
bolt, and tighten it securely.
make sure that the pulley turns smoothly after
it's reassembled.
Relief Valve Replacement
Recover the refrigerant with Recovery/Recycling/
Charging System lsee page 22-221.
Remove the relief valve and the O-ring. Plug the
opening to keep foreign matter from entering the
system and the compressor oil from running out,
NOTE:
. Do not let the compressor oil run out.
. Make sure there is no foreign matter in the sys-
tem.

4. Replace the O-ring with a new one at the relief
valve, and apply a thin coat of refrigerant oil (ND-

. Replace the O-rings with new ones at each fit-
ting, and apply a thin coat of refrigerant oil
before installing them.
NOTE: Be sure to use the right O-rings for HFC-
134a (R-1344) to avoid leakage.
a Do not damage the radiator and condenser fins
when installing the condenser.
o Be sure to install the condenser mount cushions
securely into the holes.

Troubleshooting
Tips and Precautions (cont'd)
Insert the connector all the way and make sure it is
securely locked.
Position wires so that the open end of the cover faces
down.Faceopen end
V
Handling Wires and Harnesses
I Secure wires and wire harnesses to the frame with
their respective wire ties at the designated locations.
a Remove clips carefully; don't damage their locks.
Slip pliers under the clip base and through the hole at an
angle, then squeez€ the expansion tabs to release the
clro.
sNAP-R|NG PLtERS
After installing harness clips, make sure the harness
doesn't interlere with any moving parts.
Keep wire harnesses away from exhaust pipes and
other hot parts, trom sharp edges ol brackets and
holes, and from exposed screws and bolts.

Testing and Repairs
a Do not use wires or harnesses with broken insulation.
Replace them or repair them by wrapping the break
with electrical tape.
a Atter installing parts. make sure that no wires are
oinched under them.
a When using electrical test equipment. follow the
manulacturer's instructions and those described in
this manual.
a lI possible, insert the probe of the tester {rom the wire
side {except waterproot connector).
a Seat grommets in their grooves properly.
a Use a probe with a tapered tip.
Reler to the instructions in the Honda Terminal Kit for
identification and replacement oI connector terminals.

I . Verify The Complaint
Turn on allthe components in the problem circuit to
verify the customer complaint. Note the symptoms.
Do not begin disassembly or testing until you have
narrowed down the problem area.
2- Analyze The Schomatic
Look up the schematic for the problem circuit. De-
termine how the circuit is supposed to work by trac-
ing the current paths from the power feed through
the circuit components to ground. lf several circuits
fail at the same time, the fuse or ground is a likely
Based on the symptoms and your understanding ot
the circuit operation, identity one or more possible
causes of the problem.
3. lsolata The Problem By Testing The Circuit
Make circuit tests to check the diagnosis you made
in step 2. Keep in mind that a logical, simple proce-
dure is the key to efficient troubleshooting. Test for
the most likely cause of failure lirst. Try to make
tests at points that are easilV accessible.
4. Fix The Problem
Once the specific problem is identified, make therepair. Be sure to use proper tools and safep.ocedures.
5. Make Sure The Circuit Workg
Turn on all components in the repaired circuit in allmodes to make sure you've fixed the entire problem.
lf the problem was a blown fuse, be sure to test all
of the circuits on that fuse. Make sure no newproblems turn up and the original problem does not
recuf.
