5W-30 is preferable.
If 5W-30 is not available, select the viscosity, from the chart, that
is suitable for the outside temperature range.
CAUTION:

5W-20 should only be used for QR engine models.

5W-20 is not suitable for sustained high speed driving.
Anti-Freeze Coolant Mixture RatioBLS0009E
The engine cooling system is filled at the factory with a high-quality,
year-round anti-freeze coolant solution. The anti-freeze coolant solu-
tion contains the specific solutions effective for the anti-corrosion
and the anti-freeze function. Therefore, additional cooling system
additives are not necessary.
CAUTION:

When adding or replacing coolant, be sure to use only Gen-
uine NISSAN Anti-freeze Coolant or equivalent in its quality
with the proper mixture ratio. See the examples shown
right.
The use of other types of engine coolant may damage your
cooling system.

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.

Checking Drive BeltsBLS0005J
WARNING:
Be sure to perform the following when engine is stopped.
1. Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
2. Inspect drive belt deflection at a point on the belt midway
between pulleys.

Inspection should be done only when engine is cold, or over
30 minutes after engine is stopped.

When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point.

Adjust if belt deflection exceeds the limit.
CAUTION:

When checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turning
crankshaft two turns or more, re-adjust to the specified
value to avoid variation in deflection between pulleys.

Release the tension by loosing lock nut and turning adjust-
ing bolt when adjusting the belt. Tighten once the lock nut
at 4.9 N·m (0.50 Kg-m, 43 in-lb). Then, adjust the belt ten-
sion by loosing lock nut between 45° and 90°.
Belt Deflection
Tension AdjustmentBLS0005K
CAUTION:

When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.

When deflection of belt being used exceeds “Limit”, adjust it to value for “After adjustment”.

When checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust to the specified value to avoid variation
in deflection between pulleys.

When installing belt, make sure that it is correctly engaged with pulley groove.

Keep engine oil, working fluid and engine coolant away from belt.

Do not twist or bend belt excessively.
