REMOVAL
WARNING:
Be careful not to get burn yourself, as en
gine oil and engine coolant may be hot.
NOTE:
When removing oil cooler only, step 2 is unnecessary.
1. Remove front engine undercover with power tool.
2. Drain engine coolant from radiator and cylinder block. Refer to CO-10, "
Changing Engine Coolant" and

ENGINE MAINTENANCE (VQ35DE ENGINE)
When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.
When deflection or tension of belt being used exceeds “Limit”, adjust it to value for “After adjust-
ment”.
When checking belt deflection or te nsion immediately after installation, first adjust it to the specified
value. Then, after turning crankshaft two turns or mo re, re-adjust to the specified value to avoid vari-
ation in deflection between pulleys.
When installing belt, make sure that it is correctly engaged with pulley grooves.
Keep engine oil, working fluid and engine coolant away from belt and pulley grooves.
Do not twist or bend belt excessively.
ALTERNATOR AND POWER STEERING OIL PUMP BELT
1. Remove front engine undercover with power tool.
2. Loosen idler pulley lock nut (A) and adjust tension by turning adjusting bolt (B).
For the specified belt tension, refer to EM-14, "
Checking Drive
Belts".
3. Tighten nut (A).
A/C COMPRESSOR BELT
1. Remove front engine undercover with power tool.
2. Loosen idler pulley lock nut (C) and adjust tension by turning adjusting bolt (D). For the specified belt tension, refer to EM-14, "
Checking Drive Belts".
3. Tighten nut (C).
Changing Engine CoolantINFOID:0000000001328902
WARNING:
To avoid being scalded, do not change en gine coolant when the engine is hot.
Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressu re. Then turn radiator cap all the way.
Be careful not to allow engine coolant to contact drive belts.

CHASSIS AND BODY MAINTENANCE
3. Loosen the level gauge bolt.
4. Drain ATF from drain plug and refill with new ATF. Always refillsame volume with drained ATF.
To replace the ATF, pour in new ATF at the A/T fluid charging
pipe with the engine idling, at the same time drain the old ATF
from the radiator cooler hose return side.
When the color of the ATF coming out is almost same as the color of the new ATF, the replacement is complete. The
amount of new ATF to use should be 30 to 50% increase of
the stipulated amount.
CAUTION:
Use only Genuine NISSAN Matic J ATF. Do not mix with other ATF.
Using ATF other than Genuine NISSAN Matic J AT F will cause deterioration in driveability and A/
T durability, and may damage the A/T, which is not covered by the warranty.
When filling ATF, take care not to scatter heat generating parts such as exhaust.
Do not reuse drain plug gasket.
5. Run engine at idle speed for 5 minutes.
6. Check A/T fluid level and condition. Refer to MA-26, "
Checking A/T Fluid". If ATF is still dirty, repeat step
2. through 5.
7. Install the removed A/T fluid level gauge into A/T fluid charging pipe.
8. Tighten the level gauge bolt.
Checking Transfer FluidINFOID:0000000001328921

POWER STEERING OIL PUMP
Before starting work, confirm belt tension is proper.
1. Connect oil pressure gauge (SST) and oil pressure gaugeadapter (SST) between oil pump discharge connector and high
pressure hose and then bleed air from the hydraulic circuit.
2. Start engine. Allow engine to run until tank temperature reaches 50 to 80 °C (122 to 176 °F).
CAUTION:
Warm up engine with shut-off val ve fully opened. If engine is started with shut-off valve closed,
fluid pressure in power steering pump increases to maximum. This will raise fluid temperature
excessively.
Be careful not to contact hose with belt when engine is started.
3. With engine at idle, close shut-off valve and read the relief oil pressure.
CAUTION:
Do not close shut-off valve of pressu re gauge for more than 10 seconds.
4. After measurement, open shut-off valve slowly. If relief oil pressure is outside the specification, disassemble and repair oil pump. Refer to PS-32, "
Disas-
sembly and Assembly (VK45DE Models)".
5. After inspection, disconnect oil pressure gauge (S ST) and oil pressure gauge adapter (SST) from hydrau-
lic circuit, connect oil pump discharge connector and high pressure hose. Add fluid and bleed air from
hydraulic circuit thoroughly. Refer to PS-7, "
Air Bleeding Hydraulic System".
