oil change INFINITI QX4 2001 Factory User Guide

SEF977Y
Component DescriptionNBEC0292The crankshaft position sensor (POS) is located on the oil pan
facing the gear teeth (cogs) of the signal plate (flywheel). It detects
the crankshaft position signal (1É signal).
The sensor consists of a permanent magnet, core and coil.
When engine is running, the gap between the sensor and the gear
teeth (cogs) will periodically change. Permeability near the sensor
also changes.
Due to the permeability change, the magnetic flux near the core is
changed. Therefore, the voltage signal generated in the coil is
changed.
The ECM receives the voltage signal and detects the crankshaft
position signal (1É signal).

HFC-134a (R-134a) Service Tools and
Equipment
=NBHA0009Never mix HFC-134a refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/or its lubri-
cant.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/
lubricant.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
Adapters that convert one size fitting to another must never be used: refrigerant/lubricant contamination will
occur and compressor failure will result.

Maintenance of Lubricant Quantity in
Compressor
NBHA0071The lubricant in the compressor circulates through the system with
the refrigerant. Add lubricant to compressor when replacing any
component or after a large gas leakage occurred. It is important to
maintain the specified amount.
If lubricant quantity is not maintained properly, the following mal-
functions may result:
ILack of lubricant: May lead to a seized compressor
IExcessive lubricant: Inadequate cooling (thermal exchange
interference)
LUBRICANTNBHA0071S01Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
CHECKING AND ADJUSTINGNBHA0071S02Adjust the lubricant quantity according to the test group shown
below.
1 CHECK LUBRICANT RETURN OPERATION
Can lubricant return operation be performed?
IA/C system works properly.
IThere is no evidence of a large amount of lubricant leakage.
YesorNo
Ye s©GO TO 2.
No©GO TO 3.
2 PERFORM LUBRICANT RETURN OPERATION, PROCEEDING AS FOLLOWS:
1. Start engine, and set the following conditions:
ITest condition
Engine speed: Idling to 1,200 rpm
A/C or AUTO switch: ON
Blower speed: Max. position
Temp. control: Optional [Set so that intake air temperature is 25 to 30ÉC (77 to 86ÉF).]
2.Next item is for V-5 or V-6 compressor. Connect the manifold gauge, and check that the high pressure side
pressure is 588 kPa (6 kg/cm
2, 85 psi) or higher.
If less than the reference level, attach a cover to the front face of the condenser to raise the pressure.
3. Perform lubricant return operation for about 10 minutes.
4. Stop engine.
CAUTION:
If excessive lubricant leakage is noted, do not perform the lubricant return operation.
OK©GO TO 3.
3 CHECK COMPRESSOR
Should the compressor be replaced?
YesorNo
Ye s©Go to ªLubricant Adjustment Procedure for Compressor Replacementº, (HA-148).
No©GO TO 4.

NOTE:
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) fluid (A/T, all mode 4WD transfer)/differential gear oil (exc.
LSD) at every 30,000 miles (48,000 km) or 24 months, and change LSD gear oil every 15,000 miles (24,000 km) or 12 months.
(2) Refer to ªTire rotationº under the ªGENERAL MAINTENANCEº heading earlier in this section.
(3) The propeller shaft should be re-greased after being immersed in water.
(4) If operating frequently in water, replace grease every 3,750 miles (6,000 km) or 3 months.
(5) Inspect the air bag system 10 years after the date of manufacture noted on the FMVSS certification label.
(6) Refer to SU-5, ªFront Suspension Partsº and SU-16, ªRear Suspension Partsº, AX-3, ªFront Axle Partsº and AX-18, ªRear Axle Partsº.

Changing Engine OilNBMA0015WARNING:
IBe careful not to burn yourself, as the engine oil is hot.
IProlonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Stop engine and wait for more than 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain oil and refill with new engine oil.

CAUTION:
IBe sure to clean drain plug and install with new washer.
Oil pan drain plug:

IThe refill capacity depends on the oil temperature and
drain time. Use these specifications for reference only.
Always use the dipstick to determine when the proper
amount of oil is in the engine.
JMA122D
5. Warm up engine and check area around drain plug and oil fil-
ter for oil leakage.
6. Stop engine and wait for more than 10 minutes.
7. Check oil level.

Changing Oil FilterNBMA00161. Remove oil filter with Tool.
WARNING:
Be careful not to burn yourself, as the engine and engine oil
are hot.
The filter is a full-flow cartridge type and is provided with a relief
valve.

15. Apply multi-purpose grease to cavity at sealing lips of oil seal.
Install side oil seal.
Tool number: KV38100200 (J26233)
SPD513
16. Measure ring gear to drive pinion backlash with a dial indica-
tor.
Ring gear-to-drive pinion backlash:
0.10 - 0.15 mm (0.0039 - 0.0059 in)
IIf backlash is too small, decrease thickness of right shim and
increase thickness of left shim by the same amount.
If backlash is too great, reverse the above procedure.
Never change the total amount of shims as it will change the
bearing preload.
SPD664
17. Check total preload with Tool.
When checking preload, turn drive pinion in both direc-
tions several times to set bearing rollers.
Tool number: ST3127S000 (J25765-A)
Total preload:
P

P
1: Drive pinion preload
SPD561
IIf preload is too great, remove the same amount of shim from
each side.
IIf preload is too small, add the same amount of shim to each
side.
Never add or remove a different number of shims for each side
as it will change ring gear to drive pinion backlash.
18. Recheck ring gear to drive pinion backlash because increase
or decrease in thickness of shims will cause change of ring
gear-to-pinion backlash.
SPD524
19. Check runout of ring gear with a dial indicator.
Runout limit:
0.05 mm (0.0020 in)
IIf backlash varies excessively in different places, the variance
may have resulted from foreign matter caught between the ring
gear and the differential case.
IIf the backlash varies greatly when the runout of the ring gear
is within a specified range, the hypoid gear set or differential
case should be replaced.
20. Check tooth contact. Refer to ªTOOTH CONTACTº, PD-29.
21. Install rear cover and gasket.
