*1: For further details, see “Engine Oil Recommendation”.
*2: Using automatic transmission fluid other than Genuine NISSAN Matic J ATF will cause deterioration in driveability and
automatic transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new
vehicle limited warranty.
*3: For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 0 °C (32 °F).
*4: Canada NISSAN Au tomatic Transmission Fluid or DEXRON
TM VI type ATF may also be used.
*5: Available in mainland U.S.A. through your INFINITI dealer.
Engine Oil RecommendationINFOID:0000000001328898
NISSAN recommends the use of an energy conser ving oil in order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certification and International Lubri-
cant Standardization and Approval Committee (ILSAC) certification and SAE viscosity standard. These oils
have the API certification mark on the front of the c ontainer. Oils which do not have the specified quality label
should not be used as they could cause engine damage.

POWER STEERING FLUID
Checking Fluid LevelINFOID:0000000001327709
 Stop engine before performing a fluid level check.
 Ensure that fluid level is between the MAX range and MIN level.
 Because fluid level differs within the HOT range and the COLD range, check it carefully.
CAUTION:
 Do not overfill the Max level.
 Do not reuse any used power steering fluid.
 For recommended fluid, refer to MA-9, "
Fluids and Lubricants".
Checking Fluid LeakageINFOID:0000000001327710
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 to 80 ° C (122 to
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 loos en 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-27
.
6. Check steering gear boots for accumulation of fluid indicating a from steering gear.
Air Bleeding Hydraulic SystemINFOID:0000000001327711
Incomplete air bleeding causes the following. When this happens, bleed air again.
 Generation of air bubbles in reservoir tank.
 Generation of 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 low-level line. Check tank frequently and
add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully to the right and then fully to the left, and keep for about
three seconds. Then check whether a fluid leakage has occurred.
3. Repeat the 2nd procedure several times at about three seconds intervals. CAUTION:
Do not hold steering wheel in the locked position more than 10 seconds. (There is the possibility
that oil pump may be damaged.)
4. Check generation of air bubbles and cloud in fluid.
5. If air bubbles and the cloud don't fade, stop engine, hold air bleeding until air bubbles and the cloud fade.
Perform the 2nd and the 3rd procedures again. HOT : Fluid temperatures from 50 to 80
°C (122 to
176 °F)
COLD : Fluid temperatures from 0 to 30 °C (32 to 86 °F)

2. Heat rack Teflon ring to approximately 40 °C (104 °F) with a
dryer. Assemble it to mounting groove of rack.
3. To fit rack Teflon ring on rack, use rack Teflon ring installation tool (SST) from tooth side. Comp ress rim of ring with the tool.
4. Apply recommended grease to rack oil seal. Insert rack oil seal, then insert rack assembly to gear housing assembly.
CAUTION:
 When inserting rack assembly, do not damage retainersliding part. If it is dama ged, replace gear housing assem-
bly.
 When inserting rack assembly, do not damage cylinder
inner wall. If it is damaged, it may cause oil leaks. Replace
gear housing assembly.
 Attach rack oil seal. Both in ner lip and outer lip should
face each other.
a. To avoid damaging inner rack oil seal, wrap an OHP sheet [approximately. 70 mm (2.76 in) × 100 mm (3.94 in) around rack
tooth. Place oil seal on sheet. Then, pull oil seal along with OHP
sheet until they pass the toothed se ction of rack, then remove it.
b. Insert rack oil seal (inner) to piston (rack Teflon ring) position and push retainer to adjust screw side with fingers lightly, and
then make rack move in gear housing assembly, install rack oil
seal (inner) to fit with gear housing assembly.

c. When installing outer rack oil seal, cover the end of rack with anOHP sheet [70 mm (2.76 in) × 100 mm (3.94 in)]. It will avoid
damaging rack oil seal. Then place oil seal on sheet. Pull rack oil
seal along with OHP sheet until they pass rack end. Then
remove OHP sheet.
d. Install end cover assembly to rack, move it to gear housing assembly.
5. Using a 45 mm (1.77 in) open head (suitable tool), tighten end cover assembly at the specified torque.
CAUTION:
Do not damage rack surface. If it is damaged, it may cause
oil leaks. Replace rack assembly.
6. After tightening end cover assembly, caulk cylinder at one point as shown in the figure using a punch. This will prevent end cover
from getting loose.
7. Install pinion assembly to gear housing assembly. CAUTION:
In order to protect oil seal from any damage, insert pinion
assembly out straightly.
8. Apply recommended fluid to O-ring. Install O-ring to rear cover.
9. Use a rear cover wrench (SST), install rear cover to gear hous- ing assembly.
10. Confirm projection on rear cover cap nearly fit with marking posi- tion on gear housing assembly.
11. Apply recommended thread locking sealant to the thread (2 turns thread), and then screw in the adjusting screw until it
reaches height “H” from gear housing assembly measured
before disassembling.
12. Rotate pinion ten times whole range of rack so that parts get to fit with each other.
