*3: Never use API CG-4.
*4: Use Genuine Nissan Anti-freeze Coolant (L2N) or equivalent in its quality, in order to avoid possible aluminum corrosion within the engine cooling
system caused by the use of non-genuine engine coolant.
Note that any repairs for the incidents within the engine cooling system while using non-genuine engine coolant may not be covered by
the warranty even if such incidents occurred during the warranty period.
*5: Never mix DOT 3 & DOT 4.
RECOMMENDED FLUIDS AND LUBRICANTS
MA-1008

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, addi-
tional cooling system additives are not necessary.
CAUTION:
+When 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.
+When checking the engine coolant mixture ratio by the cool-
ant hydrometer, use the chart below to correct your hydrom-
eter reading (specific gravity) according to coolant tempera-
ture.

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

Checking Drive Belt
+Because an auto tensioner adjustment mechanism is
provided, it is not necessary to check or adjust the ten-
sion 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 pro-
cedure.
a. Securely hold the 19 mm (0.75 in) hexagonal portion A of
auto tensioner with a closed wrench.
+Preferably use a tool with a handhold of 500 mm (19.69 in)
or more in length.
+No bolts or nuts are required to be loosened during the
operation.
b. Turn the hexagonal portion A in the direction shown by the
arrow to contract the damper unit of the auto tensioner.
CAUTION:
+Because the tensioner has a high tension, it shall be
securely held and turned with a closed wrench.
+Because 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.
+If 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:
+When handling the belt, pay attention to prevent the oil
or coolant from adhering to the belt.
+Do not distort or bend the belt intensively.
Installation
+Install the belt in the reverse order of removal.
+After installation of the belt, confirm that the belt engages the
pulleys securely.
+Depending 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:
+Be careful not to burn yourself, as engine oil is hot.
+Prolonged 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.

CAUTION:
+Be sure to clean and install oil pan drain plug with
washer.
Drain plug:
:54-58Nzm (5.5 - 6.0 kg-m, 40 - 43 ft-lb)
+The refill capacity changes depending on the oil tem-
perature and drain time; use these valves as a reference
and be certain to check with the dipstick when changing
the oil.
4. Check oil level.
5. Start engine. Check area around drain plug and oil filter for
any sign of oil leakage.
6. Run engine for a few minutes, then turn it off. After 10 min-
utes check oil level.
Changing Engine Oil Filter
REMOVAL
1. Insert a suitable tool with a 12.7 mm square (1/2 inch square)
such as an extension bar and ratchet handle into the filter
body, and loosen the body by approximately 4 turns.
WARNING:
Be careful not to burn yourself, as the engine and engine oil
are hot.
