< SERVICE INFORMATION >
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.

Engine oil capacity (Approximate):Unit: (US qt, lmp qt)
CAUTION:
 When filling engine oil, do not pull out oil level gauge.
 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.
8. Warm up the engine and check area around drain plug and oil filter for engine oil leakage.
9. Stop the engine and wait for 10 minutes.
10. Check the engine oil level.
Changing Oil FilterINFOID:0000000001328906
REMOVAL
WARNING:
Be careful not to get burned when the engine and engine oil may be hot.
1. Remove front engine undercover with power tool.
2. Using oil filter wrench (SST), remove oil filter. CAUTION:
 Oil filter is provided with relief valve. Use genuine NISSAN
oil filter or equivalent.
 When removing, prepare a sh op cloth to absorb any
engine oil leakage or spillage.
 Do not allow engine oil to adhere to drive belts.
 Completely wipe off any engine oil that adheres to engine and vehicle.

Checking Drive BeltsINFOID:0000000001328909
WARNING:
Be sure to perform when the engine is stopped.
 Remove air duct (inlet) when inspecting drive belt for alternator, water pump and A/C compressor.
 Remove front engine undercover with power tool when inspecting power steering oil pump belt.
 Make sure that indicator (single line notch) of eac h auto tensioner is within the allowable working range
(between three line notches).
NOTE:
 Check auto tensioner indication when engine is cold.
 When new drive belt is installed, the range should be “A”.
 The indicator notch is located on the moving side of the tensioner for alternator, water pump and A/C com-
pressor belt, while it is found on the fi xed side for power steering oil pump belt.
 Visually check entire belt for wear, damage or cracks.
 If the indicator is out of allowable working range or belt is damaged, replace belt.
Tension AdjustmentINFOID:0000000001328910
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.
Changing Engine CoolantINFOID:0000000001328911
WARNING:
 To avoid being scalded, do not change engine coolant when 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.

Checking Seat Belt, Bu ckles, Retractors, Anchors and AdjustersINFOID:0000000001328937
CAUTION:
 After any collision, inspect all seat belt assembli es, including retractors and other attached hard-
wares (I.e. anchor bolt, guide rail set). Nissan recommends to replace all seat belt assemblies in use
during a collision, unless not damaged an d properly operating after minor collision.
Also inspect seat belt assemblies no t in use during a collision, and replace if damaged or improperly
operating.
Seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal colli-
sion where the driver and passenger air bags are deployed.
 If any component of seat belt assembl y is questionable, do not repair.
Replace as seat belt assembly.
 If webbing is cut, frayed, or damaged, replace belt assembly.
 Never oil tongue and buckle.
 Use a genuine NISSAN seat belt assembly.
