Engine Coolant Mixture Ratio
The engine cooling system is filled at the factory with a high-quality,
year-round and extended life engine coolant. The high quality
engine coolant contains the specific solutions effective for the anti-
corrosion and the anti-freeze function. Therefore, additional cooling
system additives are not necessary.
CAUTION:
IWhen adding or replacing coolant, be sure to use only
Genuine Nissan Anti-freeze Coolant (L2N) or equivalent.
Because L2N is premixed type coolant (Mixture ratio 50%).
The use of other types of engine coolant may damage your
cooling system.
IWhen checking the engine coolant mixture ratio by the coolant
hydrometer, use the chart below to correct your hydrometer
reading (specific gravity) according to coolant temperature.

WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
the radiator. Wait until the engine and radiator cool down.

Drive Belt Inspection
1. Inspect for cracks, fraying, wear or oil adhesion. Replace if
necessary.
The belts should not touch the bottom of the pulley groove.
2. Check drive belt deflection by pushing on the belt midway
between pulleys. (H)
3. Adjust if belt deflections exceed the limit.

Changing Engine Oil
WARNING:
IBe careful not to burn yourself, as the engine oil is hot.
IProlonged 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 engine, and check for oil leakage from engine com-
ponents.
2. Stop engine.
3. Remove dipstick, oil filler cap and drain plug.
4. Drain oil.
5. Install drain plug.
CAUTION:
IBe sure to clean drain plug and install with new washer.
Drain plug:
: 29-39N×m(3.0 - 4.0 kg-m, 21 - 29 ft-lb)
6. Fill slowly with new oil whilst not exceeding the maximum level.

Drain and refill
With oil filter change 6.2 (5-1/2)
Without oil filter change 5.5 (4-7/8)
CAUTION:
IThe refill capacity depends on the oil temperature and
drain time. Use these specifications for reference only.
Always use the dipstick to determine when the proper
amount of oil is in the engine.
7. Install dipstick and filler cap.
8. Start engine. Check area around drain plug and oil filter for any
sign of oil leakage.
9. Run engine for a few minutes, then turn it off. After several
minutes check oil level again.
10. If necessary, add oil whilst not exceeding the maximum level.
Changing Oil Filter
1. Remove oil filter with a suitable wrench.
WARNING:
Be careful not to burn yourself as engine and oil is hot.

AIR CONDITIONER EQUIPPED MODEL
1. Make certain that the clearance between the actuator idle con-
trol lever pin and the injection pump control lever is within the
specified limits.
2. Adjust idle speed to specified rpm without the air conditioner
operating.
3. Then check the idle speed when the air conditioner is operat-
ing and make sure it is correct.

Checking Drive Belt
IBecause an auto tensioner adjustment mechanism is
provided, it is not necessary to check or adjust the tension
of accessory belt.
1. Inspect for cracks, fraying, wear or oil adhesion. Replace if
necessary.
The belts should not touch the bottom of the pulley groove.
2. Check the damper unit of the auto tensioner for oil leaks.

Removal
WATER PUMP, ALTERNATOR AND AIR CONDITIONER
BELT
1. Remove radiator shroud.
2. Contract and hold the auto tensioner using the following proce-
dure.
a. Securely hold the 19 mm (0.75 in) hexagonal portion A of auto
tensioner with a closed wrench.
IPreferably use a tool with a handhold of 500 mm (19.69 in) or
more in length.
INo bolts or nuts are required to be loosened during the opera-
tion.
b. Turn the hexagonal portion A in the direction shown by the
arrow to contract the damper unit of the auto tensioner.
CAUTION:
IBecause the tensioner has a high tension, it shall be
securely held and turned with a closed wrench.
IBecause the hexagonal portion A of the tensioner is made
of aluminum and may be damaged by sudden input, turn
it slowly according to the contraction of the damper unit.
3. Remove the belt from the alternator pulley first, and then
remove it from the other pulleys.
IIf the tensioner is not held firmly, your finger may get caught
between the belt and the pulleys. Confirm the holding of the
tensioner, and then hold the belt side in the place away from
the pulleys to attach or remove the belt, paying attention to
prevent your finger from being caught.
CAUTION:
IWhen handling the belt, pay attention to prevent the oil or
coolant from adhering to the belt.
IDo not distort or bend the belt intensively.
Installation
IInstall the belt in the reverse order of removal.
IAfter installation of the belt, confirm that the belt engages the
pulleys securely.
IDepending on the engagement between the belt and the idler
pulley, noise (belt noise) may be heard when the engine is
started just after installation. This noise will stop with time.
Changing Engine Oil
WARNING:
IBe careful not to burn yourself, as engine oil is hot.
IProlonged 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 engine, and check for oil leakage from engine com-
ponents.
2. Remove drain plug and oil filler cap.

Checking Fluid Level and Leaks (Power
steering)
Check fluid level.
Fluid level can be checked when the fluid is either hot or cold.
CAUTION:
IDo not overfill.
IRecommended fluid is Automatic Transmission Fluid
ªDEXRON
TMº type.
ICheck lines for improper attachment, leaks, cracks, damage,
loose connections, chafing and deterioration.
Greasing Steering Linkage
Apply multi-purpose grease to point shown in the illustration.
Ventilation Air Filter
FUNCTION
Air inside passenger compartment is kept clean at either recircula-
tion or fresh mode by installing ventilation air filter into cooling unit.
REPLACEMENT PROCEDURES
IRemove glove box.
Refer to BT section.
ITake out ventilation air filter which is secured with one screw,
from cooling unit.
IReplace with new one and reinstall glove box.
