NOTE:
Explained here is how to disassemble with engine stand s
upporting transmission surface. When using a differ-
ent type of engine stand, note the difference in the steps, etc.
1. Remove the engine assembly from the vehicle. Refer to EM-98, "
Exploded View".
2. Remove crankshaft pulley. Refer to EM-96, "
FRONT OIL SEAL : Removal and Installation".
NOTE:
The drive plate is fixed with a ring gear stopper [SST: KV10119200 (J-49277)]. Loosen the crankshaft pul-
ley mounting bolts before installing the engine stand.
3. Remove the parts that may restrict installation of engine to a widely used engine stand.  Fix crankshaft with a ring gear stopper [SST: KV10119200 (J-49277)]. Loosen drive plate mounting bolt
with power tool.
 Check for deformation or damage of drive plate. Refer to EM-115, "
Inspection".
NOTE:
The procedure is described assuming that you us e a widely used engine stand holding the surface, to
which transmission is installed.
4. Remove pilot converter using the pilot bushing puller (commercial service tool), if necessary.
5. Lift the engine with hoist to inst all it onto the widely used engine stand.
CAUTION:
Use an engine stand that has a load capacity [240 kg (529 lb) or more] large enough for supporting
the engine weight.
 If the load capacity of the stand is not adequate, remove the following parts beforehand to reduce the potential risk of overturning the stand.
- Remove intake manifold. Refer to EM-30, "
Exploded View".
- Remove fuel injector and fuel tube assembly. Refer to EM-48, "
Exploded View".
- Remove ignition coil. Refer to EM-29, "
Exploded View".
- Remove rocker cover. Refer to EM-33, "
Exploded View".
- Remove exhaust manifold. Refer to EM-40, "
Exploded View".
- Other removable brackets. NOTE:
The figure shows an example of widely used engine stand (A)
that can hold mating surface of transmission with drive plate
removed.
CAUTION:
Before removing the hang ing chains, check the engine
stand is stable and there is no risk of overturning.
6. Drain engine oil. Refer to LU-8, "
Draining".

5. Install the oil pressure gauge [SST: ST25051001 (J25695-1)] (A)and hose [SST: ST25052000 (J25695-2)] (B).
6. Start the engine and warm it up to normal operating temperature.
7. Check the engine oil pressure with engine running under no-load. Refer to LU-17, "
EngineOilPressure".
CAUTION:
If the difference is extreme, check the oil passages and oil pump for leaks and blockages.
8. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to the specification. Use Genuine RTV Silicone Seal ant or equivalent. Refer to GI-22, "
Recommended Chemical Prod-
ucts and Sealants".
c. After warming up engine, make sure there is no leakage of engine oil with engine running.

WARNING:
 Be careful not to burn yourself, as th e engine and engine oil may be hot.
 Prolonged 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 the engine, and check for any oil leaks.
2. Stop the engine and wait for at least 10 minutes.
3. Remove drain plug and oil filler cap to drain the old oil.
RefillingINFOID:0000000006289618
1. Install drain plug with new washer. CAUTION:
Be sure to clean drain plug and install with new washer.
2. Refill with new engine oil. Engine oil specification and viscosity:
Refer to MA-10, "
Fluids and Lubricants".
CAUTION:
 The refill capacity depends on the engine oi l temperature and drain time. Use these specifica-
tions for reference only.
 Always use oil level gauge to determine the proper amount of engine oil in engine.
3. Warm up the engine and check area around drain plug and oil filter for engine oil leakage.
4. Stop the engine and wait for 10 minutes.
5. Check the engine oil level. Refer to LU-7, "
Inspection".

transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle limited wa rranty.
*3: DEXRON™ VI type ATF may also be used.
*4: Available in mainland U.S.A. through an INFINITI dealer.
*5: Using transfer fluid other t han Genuine NISSAN Transfer Fluid will damage the transfer , which is not covered by the INFINITI new
vehicle limited warranty. See an INFINITI retailer for recommended transfer fluid.
*6: For hot climates, Viscosity SAE 90 is suitable for ambient temperatures above 0 °C (32 °F)
*7: See an INFINITI dealer for service for synthetic oil.
*8: Using Hydraulic Suspen sion fluid other than Genuine NISSAN Hydraulic Susp ension fluid will damage the Hydraulic Suspension,
which is not covered by the INFINITI new vehicle limited warranty. See an INFINITI retailer for recommended hydraulic suspensio n fluid.
*9: The fluid capacity is the reference value.
Engine Oil RecommendationINFOID:0000000006287732
NISSAN recommends the use of an energy conservi ng 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) ce rtification and SAE viscosity standard. These oils
have the API certification mark on t he front of the container. Oils which do not have the specified quality label
should not be used as they could cause engine damage.
