ENGINE MAINTENANCE (VQ23DE AND VQ35DE)

DRAINING ENGINE COOLANT
1. Remove grommet from undercover.
2. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.
When drain all of engine coolant in the system, open water drain plugs on cylinder block. Refer to
EM-229, "
DISASSEMBLY" .
3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to MA-27, "
FLUSHING COOLING SYSTEM" .
REFILLING ENGINE COOLANT
1. Install reservoir tank if removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-233,
"ASSEMBLY" .
2. Make sure that each hose clamp has been firmly tightened.
3. Remove air duct assembly. Refer to EM-131, "
AIR CLEANER AND AIR DUCT" .
4. Disconnect heater hose (left side of vehicle) at the position in
the figure.

Enhance heater hose as high as possible.
5. Fill radiator and reservoir tank to specified level.

Pour engine coolant through engine coolant filler neck
slowly of less than 2 (1-3/4 lmp qt) a minute to allow air
in system to escape.

Use NISSAN Genuine Engine Coolant or equivalent
mixed with water (distilled or demineralized). Refer to
MA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS".

When engine coolant overflows disconnected heater hose, connect heater hose, and continue filling the
engine coolant.
6. Install air duct assembly. Refer to EM-131, "
AIR CLEANER AND AIR DUCT" .
7. Install radiator cap.
8. Warm up until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3000
rpm.

Make sure thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
9. Stop engine and cool down to less than approximately 50°C (122°F).

Cool down using fan to reduce the time.

If necessary, refill radiator up to filler neck with engine coolant.
10. Refill reservoir tank to “MAX” level line with engine coolant.
11. Repeat steps 3 through 9 two or more times with radiator cap installed until engine coolant level no longer
drops.
12. Check cooling system for leaks with engine running.
13. Warm up engine, and check for sound of engine coolant flow while running engine from idle up to 3,000
rpm with heater temperature controller set at several position between “COOL” and “WARM”.

Sound may be noticeable at heater unit.
14. Repeat step 13 three times.
15. If sound is heard, bleed air from cooling system by repeating step 3 through 9 until engine coolant level no
longer drops.

Clean excess engine coolant from engine.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If cylinder block water drain plugs are removed, close and tighten them. Refer to EM-233, "
ASSEM-
BLY" .
2. Remove air duct assembly. Refer to EM-131, "
AIR CLEANER AND AIR DUCT" . Reservoir tank engine coolant capacity

1. Check for fluid leakage.
2. With the engine warmed up, drive the vehicle in an urban area.
When ambient temperature is 20°C (68°F), it takes about 10
minutes for the CVT fluid to warm up to 50 to 80°C (122 to
176°F).
3. Park the vehicle on a level surface.
4. Apply parking brake firmly.
5. With engine at idle, while depressing brake pedal, move shift
selector throughout the entire shift range.
6. Pull out the CVT fluid level gauge from the CVT fluid charging
pipe after pressing the tab on the CVT fluid level gauge to
release the lock.
7. Wipe fluid off the CVT fluid level gauge. Insert the CVT fluid
level gauge rotating 180° from the originally installed position,
then securely push the CVT fluid level gauge until it meets the
top end of the CVT fluid charging pipe.
CAUTION:
When wiping away the CVT fluid level gauge, always use
lint-free paper, not a cloth rag.
8. Place the selector lever in “P” or “N” and make sure the fluid
level is within the specified range.
CAUTION:
When reinstalling CVT fluid level gauge, insert it into the
CVT fluid charging pipe and rotate it to the original installa-
tion position until it is securely locked.
9. Check CVT fluid condition.

If CVT fluid is very dark or smells burned, check operation of
CVT. Flush cooling system after repair of CVT.

If CVT fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of CVT. Refer to CO-37,
"RADIATOR" .

PEDAL STROKE

When parking brake pedal is operated with a force of 196 N (20.0 kg, 44.1 lb), make sure parking brake
pedal stroke is within the specified number of notches. (Check it by listening and counting the ratchet
clicks.)

Make sure that brake warning lamp comes on when parking brake pedal is depressed with in one notch.
INSPECT COMPONENTS

Make sure the components are installed properly (check for looseness, backlash, etc.).

Check parking brake pedal assembly for bend, damage and cracks, and replace if necessary.

Check cable for wear and damage, and replace if necessary.

Check parking brake warning lamp switch for malfunction, and replace if necessary.
ADJUSTMENT
1. Insert a deep socket wrench to rotate adjusting nut and loosen
cable sufficiently. Then, return pedal.
2. Remove tyres from vehicle.
3. Using wheel nuts, fix disc rotor to hub and prevent it from tilting.
4. Remove adjusting hole plug installed on disc rotor. Using a flat-
bladed screwdriver, turn adjuster to clockwise in the figure until
disc rotor is locked. After locking, turn adjuster to opposite direc-
tion by 5 or 6 notches.
5. Rotate disc rotor to make sure that there is no drag. Then install
adjusting hole plug.
6. After adjusting the clearance of rear shoes, with no drag on rear
brake, adjuster cable as follows:
a. Operate pedal 10 or more times with a force of 490 N (50 kg,
11 0 l b ) .
b. Depress pedal until a deep socket wrench can be inserted.
Insert deep socket, and rotate adjusting nut to adjust pedal stroke.
CAUTION:
Do not reuse adjusting nut after removing it.
c. When parking brake pedal is operated with a force of 196 N (20.0 kg, 44.1 lb), make sure the stroke is
within the specified number of notches. (Check it by listening and counting the ratchet clicks.)
d. With parking brake pedal completely returned, make sure there is no drag on rear brake.Pedal stroke : 3 − 4 notches

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionBKS0024N

IPDM E/R (Intelligent Power Distribution Module Engine Room) integrates the relay box and fuse block
which were originally placed in engine room. It controls integrated relay via IPDM E/R control circuit.

IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control, oil
pressure switch signal, hood switch signal reception, etc.

It controls operation of each electrical part via ECM, BCM and CAN communication lines.
CAUTION:
None of the IPDM E/R-integrated relays can be removed.
SYSTEMS CONTROLLED BY IPDM E/R
FAIL-SAFE CONTROL

When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control.
After CAN communication recovers normally, it also returns to normal control.

Operation of control parts by IPDM E/R during fail-safe mode is as follows:
Control system Transmit control unit Control part
Lamp control BCM

Headlamp (HI, LO)

Parking, license plate and tail lamps

Front fog lamp
Wiper control BCM Front wiper
Rear window defogger control BCM Rear window defogger
A/C compressor control ECM A/C compressor (magnet clutch)
Cooling fan control ECM Cooling fan
Horn control BCM Horn
Controlled system Fail-safe mode
Headlamp

With the ignition switch ON, low beam headlamp is ON.

With the ignition switch OFF, low beam headlamp is OFF.
Parking, license plate and tail lamps

With the ignition switch ON, parking, license plate and tail lamps are ON.

With the ignition switch OFF, parking, license plate and tail lamps are OFF.
Cooling fan

With the ignition switch ON, cooling fan HI operates.

With the ignition switch OFF, cooling fan stops.
Front wiperUntil the ignition switch is turned OFF, front wiper LO and HI remains in the same status it was
in just before fail−safe control was initiated.
Rear window defogger Rear window defogger is OFF.
A/C compressor A/C compressor is OFF.
Front fog lamp Front fog lamp is OFF.
