GASOLINE ENGINE OIL 

SAE 5W-30 viscosity oil is preferred for all temperatures. SAE
10W-30 and 10W-40 viscosity oil may be used if the ambient
temperature is above -18

°

C(0

°

F). 

Anti-Freeze Coolant Mixture Ratio

ALS0009F

The engine cooling system is filled at the factory with a high-quality,
year-round, anti-freeze coolant solution. The anti-freeze solution
contains rust and corrosion inhibitors. Therefore, additional cooling
system additives are not necessary.

CAUTION:

When adding or replacing coolant, be sure to use only Genuine
Nissan Long Life Antifreeze/ Coolant or equivalent with the
proper mixture ratio of 50% anti-freeze and 50% demineralized
water/distilled water.
Other types of coolant solutions may damage your cooling sys-
tem.

Checking Drive Belts

ALS00062

WARNING:

Be sure to perform when engine is stopped.

Remove air duct (inlet) when inspecting drive belt for alternator, water pump and A/C compressor.

Remove engine undercover (with power tool) when inspecting power steering oil pump belt.

Make sure that indicator (single line notch) of each auto tensioner is within the allowable working range
(between three line notches).

NOTE:

Check the auto tensioner indication when engine is cold.

When new drive belt is installed, the range should be A.

The indicator notch is located on the moving side of the tensioner for alternator, water pump and A/C
compressor belt, while it is found on the fixed side for power steering oil pump belt. 

Visually check entire belt for wear, damage or cracks.

If the indicator is out of allowable working range or belt is damaged, replace the belt.

Tension Adjustment

ALS00063

Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.

Changing Engine Coolant

ALS00064

WARNING:

To avoid being scalded, never change engine coolant when engine is hot.

Wrap a thick cloth around cap and carefully remove cap. First, turn cap a quarter of a turn to
release built-up pressure. Then turn cap all the way.

DRAINING ENGINE COOLANT

1.

Remove engine undercover with power tool.

2.

Open radiator drain plug at the bottom of radiator, and remove radiator cap. 

CAUTION:

Be careful not to allow engine coolant to contact drive belts.

When draining all of engine coolant in the system, open water drain plugs on engine cylinder block.
Refer to 

EM-81, "DISASSEMBLY"

 .

3.

Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to 

MA-14, "FLUSHING COOLING SYSTEM"

 .

4.

Remove reservoir tank, drain engine coolant and clean reservoir tank before installing.

REFILLING ENGINE COOLANT

1.

Install reservoir tank if removed, and radiator drain plug.

CAUTION:

Be sure to clean drain plug and install with new O-ring.

If cylinder block water drain plugs are removed, close and tighten them. Refer to 

EM-85, "ASSEM-

BLY"

 .

2.

Remove air relief plug on heater hose.

3.

Fill radiator and reservoir tank to specified level.

Use Genuine Nissan Long Life Antifreeze/ Coolant or
equivalent mixed with water (distilled or demineralized).
Refer to 

MA-10, "RECOMMENDED FLUIDS AND LUBRI-

CANTS"

 . 

Pour engine coolant through engine coolant filler neck
slowly of less than 2  (2-1/8 US qt, 1-3/4 Imp qt) a minute
to allow air in system to escape.

When engine coolant overflows air relief hole on heater hose,
install air relief plug.

4.

Warm up engine to normal operating temperature with radiator
cap installed.

5.

Run engine at 3,000 rpm for 10 seconds and return to idle
speed.

Repeat two or three times.

CAUTION:

Watch engine coolant temperature gauge so as not to overheat engine.

6.

Stop engine and cool down to less than approximately 50

°

C (122

°

F).

Cool down using a fan to reduce the time.

If necessary, refill radiator up to filler neck with engine coolant.

7.

Refill reservoir tank to MAX level line with engine coolant.

8.

Repeat steps 3 through 6 two or more times with radiator cap installed until engine coolant level no longer
drops.

9.

Check cooling system for leaks with engine running.

Sound may be noticeable at heater unit.

11. Repeat step 10 three times.
12. If sound is heard, bleed air from cooling system by repeating steps 3 through 6 until engine coolant level

no longer drops.   

Clean excess engine coolant from engine.

FLUSHING COOLING SYSTEM

1.

Install reservoir tank, and radiator drain plug.

If cylinder block water drain plugs are removed, close and tighten them. Refer to 

EM-85, "ASSEM-

BLY"
