REMOVAL AND INSTALLATION
1. Use refrigerant collecting equipment (for HFC-134a) to discharge refrigerant.
2. Remove the liquid tank.
3. Using a vise, secure liquid tank, and remove dual-pressure
switch.
CAUTION:
● When working, be careful not to damage the compressor
fan.
●Apply compressor oil to the O-ring of the refrigerant
pressure sensor when installing it.
Condenser AssemblyEJS0020R
REMOVAL
1. Use refrigerant collecting equipment (for HFC-134a) to dis-
charge refrigerant.
2. Disconnect the high-pressure flexible hose and the high-pres-
sure pipe from the condenser.
CAUTION:
Cap or wrap the joint of the pipe with suitable material such
as vinyl tape to avoid the entry of air.
3. Remove the battery and battery tray.
4. Remove the front grille and radiator mounting bracket.
5. Remove the mounting nuts from the condenser upper bracket.
6. Remove the radiator from the lower mount, move it to the engine
side, then remove the condenser between the radiator and the radiator core support.
CAUTION:
Be careful not to damage the core surface of the condenser and the radiator.
INSTALLATION
CAUTION:
●Replace the O-rings of the high-pressure pipe and the high-pressure flexible hose with new ones,
then apply compressor oil to them after installing them.
●When pouring refrigerant, check for leaks.Tightening torque :9.8 - 11.7 N·m (1.0 - 1.2kg·m, 87 -

Checking for Refrigerant LeaksEJS0020U
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant leakage may indicate an area of refrigerant leakage. Allow
extra inspection time in these areas when using either an electronic refrigerant leak detector or fluorescent
dye leak detector.
If dye is observed, confirm the leak with an electronic refrigerant leak detector. It is possible a prior leak was
repaired and not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic leak detector, move the probe along the suspected
leak area at 1 to 2 inches per second and no further than 1/4 inch from the component.
CAUTION:
Moving the electronic leak detector probe slower and closer to the suspected leak area will improve
the chances of finding a leak.
Checking System for Leaks Using the Fluorescent Leak DetectorEJS0020V
1. Check A/C system for leaks using the UV lamp and safety glasses (J-42220) in a low sunlight area (area
without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a bright
green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain opening indi-
cates an evaporator core assembly (tubes, core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner (J-43872) to prevent future misdiag-
nosis.
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant
leak detector.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and lubricants, may falsely trigger the leak detector. Make sure the surfaces to be
checked are clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings
and may damage the detector.

PRECAUTIONSNJAX0001When installing rubber parts, final tightening must be car-
ried out under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
After installing removed suspension parts, check wheel
alignment and adjust if necessary.
Use flare nut wrench when removing or installing brake
tubes.
Always torque brake lines when installing.

REMOVALNJAX0029CAUTION:
Before removing the rear wheel hub assembly, disconnect
the ABS wheel sensor from the assembly. Then move it
away from the hub assembly. Failure to do so may result
in damage to the sensor wires and the sensor becoming
inoperative.
Wheel hub bearing does not require maintenance. If any of
the following symptoms are noted, replace wheel hub
bearing assembly.
1) Growling noise is emitted from wheel hub bearing dur-
ing operation.
2) Wheel hub bearing drags or turns roughly. This occurs
when turning hub by hand after bearing lock nut is tight-
ened to specified torque.
