INSTALLATION SERVICE POINT
.
>>A<< FLEXIBLE SUCTION HOSE CONNECTION
To prevent mis-alignment of suction hose to bracket use the
folowing assembly procedure.
1. Insert hoseconnector into compressor and hand start bolt.
2. Assemble P-clip to hose and suction hose bracket. Tighten
bolt.
3. Tighten bolt between compressor and hose connector.
.
>>B<< COMPRESSOR INSTALLATION
If a new compressor is installed, first adjust the amount of oil
according to the procedures described below, and then install
the compressor.
1. Measure the amount (X ml) of oil within the removed
compressor.
2. Drain (from the new compressor) the amount of oil
calculated according to the following formula, and then
install the new compressor.
New compressor oil amount = 140 ml
140 ml
X ml = Y ml
NOTE: Y ml indicates the amount of oil in the refrigerant line,
the condenser, the evaporator, etc.
NOTE: When replacing the following parts at the same times as
the compressor, subtract the rated oil amount of each part from
Y ml and discharge from the new compressor.
Compressor oil: ND Oil 8
Quantity:
Evaporator: 40 ml
Condenser: 40 ml

>>A<< DRYER REMOVAL PROCEDURE
1. Remove the condenser assembly from the vehicle to access
the modulator.
2. Remove the modulator cap using a14 mm hexagon wrench.
3. Remove the desiccant bag from the modulator.
Do not remove the desiccant bag from the plastic bag until
just before inserting it into the modulator.
.
<<B>> DRYER REPLACEMENT PROCEDURE
1. Fit the desiccant bag with the welded portion facing the
bottom of the modulator towards the screw-thread end.
2. Add 40 ml of ND Oil 8 into system to balance the oil
removed from the system.
3. Tighten the cap to the required torque.

1.0 Nm
Because the plastic cap has a large, 14 mm hex socket, it
is susceptible to generating excessive torque. Therefore,
be careful not to damage the crown portion of the cap.

O-RING REPLACEMENT
1.Removal- use a wooden toothpick or plastic awl to remove
o-ring without damaging the tube.
2.Installation- lubricate o-ring with ND-Oil 8, roll the
new o-ring into captured position.
.
PIPE JOINT PRECAUTIONS
1. Before making any hose and tube connections, always
apply ND-Oil 8 compressor oil to o-ring.
Avoid applying oil in areas with acrylic resin or ABS plastic
as it causes enviromental stress cracking to these resins.
2. Ensure the connecting parts are free of foreign material.

HOW TO DIAGNOSE
GENERAL <ELECTRICAL>00E-6
5. Ohmmeter
An ohmmeter is used to check continuity or measure
resistance of a switch or coil. If the measuring range has
been changed, the zero point must be adjusted before
measurement.
CHECKING FUSESM1001005000044
A blade type fuse has test taps provided to allow checking of
the fuse itself without removing it from the fuse block. The fuse
is okay if the test light comes on when its one lead is connected
to the test taps (one at a time) and the other lead is grounded.
Remember to turn the ignition switch to ON to ensure all cir-
cuits are live.
CAUTIONS IN EVENT OF BLOWN FUSE
When a fuse is blown, there are two probable causes. One is
that it is blown due to flow of current exceeding its rating. The
other is that it is blown due to repeated on/off current flowing
through it. Which of the two causes is responsible can be easily
determined by visual check as described below.
1. Fuse blown due to current exceeding rating
The illustration shows the state of a fuse blown due to this
cause. In this case, do not replace the fuse with a new one
hastily since a current heavy enough to blow the fuse has
flowed through it. First, check the circuit for shorts and check
for abnormal electric parts. After correcting shorts or
replacing parts, use only a fuse of the same capacity as a
replacement. Never use a fuse of larger capacity than the
original fuse. If a larger capacity fuse is used, electric parts
or wiring could be damaged, or could start a fire.
2. Fuse blown due to repeated turning current on and off
The illustration shows the state of a fuse blown due to
repeated current on/off. Normally, this type of problem
occurs after a fairly long period of use and is less frequent
than above. In this case, simply replace with a new fuse of
the same capacity.

HOW TO DIAGNOSE
GENERAL <ELECTRICAL>00E-8
CHECKING RELAYSM1001004900152
1. By using a relay, a heavy current can be turned on and off by
a switch using much less current. For example, in the circuit
shown here, when the switch is turned on (closed), current
flows to the coil of the relay. Then, its contact is turned on
(closed) and the light comes on. The current flowing through
the switch is much less than that for the light.
2. When current flows through the coil of a relay, its core is
magnetized to attract the iron piece, closing (ON) the
contact at the tip of the iron piece. When the coil current is
turned off, the iron piece returns to its original position by a
spring, opening the contact (OFF).
3. Relays may be classified as the normally open-type or the
normally closed-type, depending on their contact
construction.
NOTE: The deenergised state means that no current is flow-
ing through the coil. The energised state means that current
is flowing through the coil.
(1) The normally open-type
When a normally open relay as illustrated here is
checked, there should be no continuity between terminals
3 and 4 when the relay is deenergised. There should be
continuity between terminals 3 and 4 when battery
voltage and ground are applied to terminals 1 and 2. The
relay condition is determined by this check.
NOTE: Check the relay in both situation which is
energised and is not energised.
(2) The normally closed-type
When a normally closed relay as illustrated here is
checked, there should be continuity between terminals 3
and 4 when the relay is deenergised. There should be no
continuity between terminals 3 and 4 when battery
voltage and ground are applied to terminals 1 and 2. The
relay condition is determined by this check.
NOTE: Check the relay in both situation which is
energised and is not energised.

ENGINE COOLING DIAGNOSIS
ENGINE COOLING14-4
INSPECTION PROCEDURE 2: Engine Overheating
DIAGNOSIS
STEP 1. Remove the radiator cap and check for coolant
contamination.
Q: Is the coolant contaminated with rust and oil?
YES : Replace it. Refer to P.14-27.
NO : There is no action to be taken. Go to Step 2.
STEP 2. Check the radiator cap valve opening pressure.
NOTE: Be sure that the cap is clean before testing. Rust or
other foreign material on the cap seal will cause an improper
reading.
(1) Use a cap adapter to attach the cap to the tester.
(2) Increase the pressure until the gauge indicator stops
moving.
Minimum limit: 83 kPa (12 psi)
Standard value: 93
123 kPa (14 18 psi)
Q: Does the reading remain at or above the minimum limit?
YES : Go to Step 3.
NO : Replace the radiator cap. Then go to Step 5.
STEP 3. Check thermostat operation.
Refer to 38.
Q: Does the thermostat operate correctly?
YES : Go to Step 4.
NO : Replace the thermostat, then go to Step 5.
STEP 4. Check the drive belt for slippage or damage.
Refer to GROUP 00, Maintenance Service
Drive Belts
(Check Condition). <3.8L Engine>39 .
Q: Is the drive belt loose or damaged?
YES : Adjust or replace the drive belt, then go to Step 5.
NO : There is no action to be taken.
STEP 5. Retest the system.
Check the engine coolant temperature.
Q: Is the engine coolant temperature abnormally high?
YES : Return to Step 2.
NO : The procedure is complete.
