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 -

pressure such that vehicle stopping time equals 3 to 5 sec-
onds.
3. To cool the brake system, drive the vehicle at 50 km/h (31
MPH) for 1 minute without stopping.
4. Repeat steps 1 to 3, 10 times or more to complete the burnish-
ing procedure.

Bleeding Brake SystemNJBR0009CAUTION:
Carefully monitor brake fluid level at master cylinder dur-
ing bleeding operation.
Fill reservoir with new brake fluid “DOT 4”. Make sure it is
full at all times while bleeding air out of system.
Place a container under master cylinder to avoid spillage
of brake fluid.
For models with ABS, turn ignition switch OFF and dis-
connect ABS actuator connectors or battery ground cable.
SBR419C
Bleed air in the following order.
Right rear brake,Left front brake,Left rear brake,Right
front brake
1. Connect a transparent vinyl tube to air bleeder valve.
2. Fully depress brake pedal several times.
3. With brake pedal depressed, open air bleeder valve to release
air.
4. Close air bleeder valve.
5. Release brake pedal slowly.
6. Repeat steps 2. through 5. until clear brake fluid comes out of
air bleeder valve.

ABS Actuator and Electric UnitNJBR0162Disconnect each ABS actuator and electric unit E217 connector.
Confirm continuity and resistance value between each pair of ABS
actuator and electric unit harness connector.
CAUTION:
Be sure ABS motor is securely grounded.
Basic Inspection 1 Brake Fluid Level and
Leakage Inspection
NJBR01631. Check fluid level in brake reservoir tank. If fluid level is low,
refill brake fluid.
2. Check area around brake piping and ABS actuator and elec-
tric unit for leaks. If a leak or oozing is detected, check as fol-
lows:
If connections at ABS actuator and electric unit are loose,
tighten piping to the specified torque. Then check again for
leaks, and be sure there is no fluid leak.
If the flare nuts at the connections and the threads of the ABS
actuator and electric unit are damaged, replace the damaged
parts. Then check again for leaks, and make sure that there is
no fluid leak.
If leak or oozing is detected except for ABS actuator and elec-
tric unit connections, wipe it with clean cloth. Then check again
for leaks. If there is still leak or oozing, replace damaged part.
If leak or oozing is detected on ABS actuator and electric unit,
wipe with a clean cloth. Check again for leaks, and if there is
still leak or oozing, replace ABS actuator and electric unit.
CAUTION:
ABS actuator and electric unit body cannot be disassembled.
Basic Inspection 2 Inspection for Loose Power
Supply Terminal
NJBR0164Check battery for looseness on battery positive/negative terminals
and ground connection.
