On-Vehicle ServiceINFOID:0000000009460536
CHECKING COMPRESSION PRESSURE
1. Run the engine until it reaches normal operating temperature.
2. Turn the ignition switch to OFF.
3. Release fuel pressure and leave t he fuel pump electrically disconnected.
Refer to EC-687, "Work Procedure"
.
4. Remove all six spark plugs. Refer to EM-132, "Removal and Installation"
.
5. Install the compression tester with the adapter into the spark plug hole. • Use compression tester whose end (a) (rubber portion) is
smaller than 20 mm (0.79 in) in diameter. Otherwise, it may be
caught by cylinder head during removal.
6. Depress accelerator pedal fully to keep the electric throttle control actuator butterfly-valve wide open to
maximize air intake flow.
7. Crank the engine and record the highest gauge indication.
8. Repeat the measurement on each cylinder (steps 5 - 7). NOTE:
Always use a fully charged battery to obtain specified engine speed.
Unit: kPa (kg/cm2, psi)/rpm
9. If compression in one or more cylinders is low:
a. Pour a small amount of engine oil into cylinders through the spark plug holes.
b. Retest compression (steps 5 - 8).
• If adding oil helps raise compression pressure, then the piston rings may be worn or damaged. If so, replace piston rings after checking piston.
• If the pressure stays low, a valve may be sticking or is seating improperly. Inspect and repair the valve and/
or valve seat. Refer to EM-212, "Inspection After Disassembly"
. If the valve and/or valve seat is damaged
replace as necessary.
• If compression stays low in two or more cylinders that are next to each other:
- The cylinder head gasket may be leaking.
- Both cylinders may have valve component damage. Inspect and repair as necessary.

The following tables show the normal maintenanc e schedule. Depending upon weather and atmospheric con-
ditions, varying road surfaces, indi vidual driving habits and vehicle usage, additional or more frequent mainte-
nance may be required.
Periodic maintenance beyond th e last period shown on the tables requires similar maintenance.

PERIODIC MAINTENANCE
NOTE:
• (1) After 40,000 miles (64,000 km) or 48 months, inspect every 10,000 miles (16,000 km) or 12 months. Replace the drive belts if
found damaged.
• (2) If operating mainly in dusty conditions, more frequent maintenance may be required.
• (3) Maintenance-free item. For service procedures, refer to the FL section.
• (4) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles (120,000 km) or 60 months.
• (5) Use only Genuine NISSAN long life Antifreeze/Coolant (blue) or equivalent with proper mixture ratio of 50% anti-freeze and 50%
demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water will reduce the life expec tancy of the
factory fill coolant.
• (6) Replace spark plug when the plug gap exceeds 1.25 mm (0.049 in) even if within specified periodic replacement mileage.
• (7) Periodic maintenance is not required. However, if valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and inter vals are
required.
