GASOLINE ENGINE OIL

SAE 5W-30 viscosity oil is preferred for all temperatures. SAE
10W-30 or 10W-40 viscosity oils may be used if the ambient
temperature is above -18°C (0°F).

Use of 5W-30 viscosity oil will increase fuel economy.
ANTI-FREEZE COOLANT MIXTURE RATIO
The engine cooling system is filled at the factory with a high-quality, long life, year-round, anti-freeze coolant
solution. The anti-freeze solution contains rust and corrosion inhibitors. Therefore, additional cooling system
additives are not necessary.
CAUTION:

When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Anti-freeze
coolant or equivalent with the proper mixture ratio of 50% anti-freeze and 50% demineralized water
or distilled water.

Other types of coolant solutions may damage your cooling system.

3. Open the radiator drain plug at the bottom of the radiator, and
remove the radiator filler cap. This is the only step required
when partially draining the cooling system (radiator only).
CAUTION:
Do not to allow the coolant to contact the drive belts.
4. When draining all of the coolant in the system for engine
removal or repair, it is necessary to drain the cylinder block.
Remove the RH cylinder block drain plug to drain the right bank
and the oil cooler hose to drain the left bank as shown.
5. Remove the reservoir tank to drain the engine coolant, then clean the reservoir tank before installing it.
6. Check the drained coolant for contaminants such as rust, corrosion or discoloration.
If the coolant is contaminated, flush the engine cooling system. Refer to MA-15, "
FLUSHING COOLING
SYSTEM" .
REFILLING ENGINE COOLANT
1. Close the radiator drain plug. Install the reservoir tank, cylinder block drain plug, and the oil cooler hose, if
removed for a total system drain or for engine removal or repair.

The radiator must be completely empty of coolant and water.

Apply sealant to the threads of the cylinder block drain plug. Use Genuine High Performance Thread
Sealant or equivalent. Refer to GI-45, "
RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS" .
2. Set the vehicle heater controls to the full HOT and heater ON position. Turn the vehicle ignition ON with
the engine OFF as necessary to activate the heater mode.
3. Remove the vented reservoir cap and replace it with a non-vented reservoir cap before filling the cooling
system.

2. Remove the drain plug and drain the final drive oil.
3. Apply sealant to the drain plug threads.

Use High Performance Thread Sealant or equivalent. Refer to GI-45, "Recommended Chemical Prod-
ucts and Sealants" .
4. Install the drain plug and tighten to specification.
5. Refill the rear final drive with new specified oil.
6. Check the oil level.
NOTE:

7. Install the filler plug and tighten to specification.
Balancing WheelsELS001H4
REMOVAL
1. Using releasing agent, remove double-faced adhesive tape from the wheel.
CAUTION:

Be careful not to scratch the wheel during removal.

After removing double-faced adhesive tape, wipe clean traces of releasing agent from the
wheel.
WHEEL BALANCE ADJUSTMENT

If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for wheels.
1. Set wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.
2. When inner and outer imbalance values are shown on the wheel balancer indicator, multiply outer imbal-
ance value by 1.6 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value and install it to the designated outer position of, or at the desig-
nated angle in relation to the road wheel.
CAUTION:

Do not install the inner balance weight before installing the outer balance weight.

Before installing the balance weight, be sure to clean the mating surface of the wheel.
Indicated imbalance value × 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance
weight (closer to calculated balance weight value)
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 g = 35 g (1.23 oz)
37.5 g = 40 g (1.41 oz)Drain plug : Refer to FFD-13, "
COMPONENTS" (FFD), RFD-12, "Components"

POWER STEERING FLUID
Revision: October 20052005 QX56
POWER STEERING FLUIDPFP:KLF20
Checking Fluid LevelEGS000U9
Check fluid level, referring to the scale on reservoir tank.
Use HOT range for fluid temperatures of 50° – 80°C (122° – 176°F).
Use COLD range for fluid temperatures of 0° – 30°C (32° – 86°F).
CAUTION:

Do not overfill.

Do not reuse any used power steering fluid.

Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to MA-11, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
Checking Fluid LeakageEGS000UA
Check the hydraulic piping lines for improper attachment and for
leaks, cracks, damage, loose connections, chafing or deterioration.
1. Run engine until fluid temperature reaches 50° – 80°C (122° –
176°F) in reservoir tank. Keep engine speed idle.
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each “lock” position for five seconds to
check fluid leakage.
CAUTION:
Do not hold steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not over tighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to PS-26, "
POWER STEERING OIL
PUMP" .
6. Check steering gear boots for accumulation of fluid indicating a leak from the steering gear.
Air Bleeding Hydraulic SystemEGS000UB
Incomplete air bleeding causes the following. When this happens, bleed air again.

Air bubbles in reservoir tank.

Clicking noise in oil pump.

Excessive buzzing in oil pump.
NOTE:
When vehicle is stationary or while steering wheel is being turned slowly, some noise may be heard from
oil pump or gear. This noise is normal and does not affect any system.
1. Stop engine, and then turn steering wheel fully to right and left several times.
CAUTION:
Do not allow steering fluid reservoir tank to go below the MIN level line. Check tank frequently and
add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully right and then fully left, hold for about three seconds.
Then check for fluid leakage.
3. Repeat step 2 several times at about three second intervals.
CAUTION:
Do not hold steering wheel in the locked position for more than 10 seconds. (There is the possibil-
ity that oil pump may be damaged.)
4. Check for air bubbles or cloudy fluid.
5. If air bubbles or cloudiness still exists, stop engine, perform steps 2 and 3 again until air bubbles or cloud-
iness does not exist.
6. Stop engine, check fluid level.

ting loose.
7. Install sub-gear assembly to gear housing assembly.
CAUTION:
Oil seal may be damaged if sub-gear assembly is not installed correctly.
8. Apply Genuine NISSAN PSF or equivalent to O-ring. Refer to MA-11, "
RECOMMENDED FLUIDS AND
LUBRICANTS" . Then install O-ring to rear cover.
NOTE:
Do not reuse O-ring.
9. Install rear cover to gear housing assembly using Tool.
10. Make sure projection on rear cover cap aligns with mark on gear housing assembly.
11. Apply thread locking sealant (Refer to GI-45, "
RECOMMENDED
CHEMICAL PRODUCTS AND SEALANTS" ) to the thread of
the adjusting screw. Then set adjusting screw height from gear
housing assembly. The adjusting screw height is the same as it
was measured previously.
12. Rotate pinion ten times through entire rack range to seat gears and to check operation.
13. With steering gear in neutral position, measure pinion rotating
torque using Tool from within –180° to +180°, while applying and
holding maximum torque to pinion gear.
14. After loosening adjusting screw once, tighten it again with torque of 5.4 N·m (0.55 kg-m, 48 in-lb). Then
loosen it within 20° – 40°.
