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:
I
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.
I
When 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. (

)
3. Adjust if belt deflections exceed the limit.

Changing Engine Oil
WARNING:
I
Be careful not to burn yourself, as the engine oil is hot.
I
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. Stop engine.
3. Remove dipstick, oil filler cap and drain plug.
4. Drain oil.
5. Install drain plug.
CAUTION:
I
Be sure to clean drain plug and install with new washer.
Drain plug:
: 29 - 39 N
⋅
m(3.0 - 4.0 kg-m, 21 - 29 ft-lb)
6. Fill slowly with new oil whilst not exceeding the maximum level.
Oil specification and viscosity:

See “RECOMMENDED FLUIDS AND LUBRICANTS” (MA-
17).
Oil capacity (Approximately):
Unit:

Drain and refill
With oil filter change
6.2 (5-1/2)
Without oil filter change
5.5 (4-7/8)
CAUTION:
I
The 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.
