INSPECTION AFTER REMOVAL
Use standard type spark plug for normal condition.
The hot type spark plug is suitable when fouling occurs with the standard type spark plug under conditions
such as:
Frequent engine starts
Low ambient temperatures
The cold type spark plug is suitable when spark knock occurs with the standard type spark plug under condi-
tions such as:
Extended highway driving
Frequent high engine revolution
CAUTION:
Do not drop or shock spark plug.
Do not use a wire brush for cleaning.
If plug tip is covered with carbon, spark plug cleaner may
be used.
Checking and adjusting plug gap is not required between
change intervals.
INSTALLATION
Install in the reverse order of removal.
Checking EVAP Vapor LinesALS000GO
1. Visually inspect EVAP vapor lines for improper attachment and for cracks, damage, loose connections,
chafing and deterioration.
2. Inspect fuel tank filler cap vacuum relief valve for clogging, sticking, etc.
Refer to EC-643, "
EVAPORATIVE EMISSION SYSTEM" .

Checking Drive BeltsALS000GP
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 undercover (with power tool) when inspecting power steering oil pump belt.
Make sure that indicator (single line notch) of each automatic tensioner is within the allowable working
range (between three line notches).
NOTE:
Check the auto tensioner indication when the engine is cold.
When the 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
compressor belt, while it is found on the fixed 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 the belt.
Tension AdjustmentALS000GQ
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.
Changing Engine CoolantALS000H6
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 pressure. Then turn radiator cap all the way.

DRAINING ENGINE COOLANT
1. Remove engine front undercover with power tool.
2. Open radiator drain plug at the bottom of radiator, and then
remove radiator cap.
Be careful not to allow engine coolant to contact drive
belts.
When draining all of engine coolant in the system, open water drain plugs on engine cylinder
block. Refer to EM-241, "
DISASSEMBLY" .
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to MA-23, "
FLUSHING COOLING SYSTEM" .
4. Remove reservoir tank, drain engine coolant and clean reservoir tank before installing.
REFILLING ENGINE COOLANT
1. Install reservoir tank, and radiator drain plug.
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring.
If cylinder block water drain plugs are removed, close and tighten them. Refer to EM-244, "
ASSEM-
BLY" .
2. Remove air relief plug on heater hose.
3. Fill thermostat housing and reservoir tank to specified level.
Refill engine coolant up to filler neck of thermostat housing.
Pour engine coolant through engine coolant filler neck slowly of less than 2 (2-1/8 US qt, 1-3/4
Imp qt) a minute to allow air in system to escape.
Use Genuine NISSAN Long Life Antifreeze/Coolant or equivalent mixed with water (distilled or
demineralized). Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

CAUTION:
Be sure to clean drain plug and install with new washer.
7. Refill with new engine oil.
Engine oil specification and viscosity:
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
Engine oil capacity (Approximate):
Unit: (US qt, Imp qt)
CAUTION:
The refill capacity depends on the engine oil 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 the engine.
