RECOMMENDED FLUIDS AND LUBRICANTS
Engine Coolant Mixture Ratio
ELS001JC
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:
lWhen adding or replacing coolant, be sure to use only Gen-
uine NISSAN Anti-freeze Coolant (L250) or equivalent in its
quality. Because L250 is premixed type coolant.
The use of other types of engine coolant may damage your
cooling system.
lWhen 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.
Mixed coolant specific gravity
Unit: specific gravity
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator. Wait until the engine and radiator cool down.

Checking Drive BeltsELS001JO
lBefore inspecting engine, make sure engine has cooled down; wait approximately 30 minutes after engine
has been stopped.
lVisually inspect all belts for wear, damage or cracks on contacting surfaces and edge areas.
lMeasure deflection at the marked point ( ).
CAUTION:
lWhen 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 varia-
tion in deflection between pulleys.
lTighten idler pulley lock nut by hand and measure deflection without looseness.

Deflection Adjustment
ELS001JP
lAdjust belts with the parts shown below.
CAUTION:
lWhen a new belt is installed as a replacement, adjust it to the specified value under “New” value
because of insufficient adaptability with pulley grooves.
lIf the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.
lWhen checking belt tension immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust it to the specified value to avoid vari-
ation in deflection between pulleys.
lMake sure the belts are fully fitted into the pulley grooves during installation.
lHandle with care to avoid smearing the belts with engine oil or engine coolant.
lDo not twist or bend the belts with strong force.

Changing Engine CoolantELS001JQ
WARNING:
lTo avoid being scalded, do not change engine coolant when engine is hot.
lWrap a thick cloth around cap and carefully remove radiator cap. First, turn radiator cap a quarter
of a turn to release built-up pressure. Then turn the cap all the way.
DRAINING ENGINE COOLANT
1. Open radiator drain plug (1) at the bottom of radiator, and
remove radiator cap.
CAUTION:
Be careful not to allow engine coolant to contact drive belts.
When draining all engine coolant in the system, also perform the following steps.
2. Remove air relief plug (1) on heater feed tube.

4. Remove reservoir tank, drain engine coolant, then clean reservoir tank.
5. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush engine cooling system. Refer toMA-21, "
