On Board Diagnosis LogicBBS0052V
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.
This self-diagnosis has the one trip detection logic.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to CO-34, "
Changing Engine
Coolant" . Also, replace the engine oil. Refer to LU-21, "Changing Engine Oil" .
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-15, "
Anti-Freeze Coolant Mixture Ratio" .
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckBBS0052W
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
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.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to EC-581,
"Diagnostic Procedure" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-581,
"Diagnostic Procedure" .
3. Turn ignition switch ON.

Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.

If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.

Battery posts, terminals and related accessories contain lead
and lead compounds. Wash hands after handling.

To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.

Dispose of or recycle drained oil or the solvent used for cleaning
parts in an appropriate manner.

Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.

Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.

Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.

Replace inner and outer races of tapered roller bearings and needle bearings as a set.

Arrange the disassembled parts in accordance with their assembled locations and sequence.

Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.

After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.

Use only the fluids and lubricants specified in this manual.

Use approved bonding agent, sealants or their equivalents when required.

Use hand tools, power tools (disassembly only) and recom-
mended special tools where specified for safe and efficient ser-
vice repairs.

When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.

Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.

SAE Viscosity NumberBLS0009D
GASOLINE ENGINE

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.
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 BeltsBLS00090
WARNING:
Be sure to perform this step when the engine is stopped.

Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use
range (between three line notches on moving side).
NOTE:

Check the drive belt auto-tensioner indication when engine is cold.

When new drive belt is installed, the indicator (notch on fixed side) should be within the range “a” in the
figure.

Visually check entire belt for wear, damage or cracks.

If the indicator (notch on fixed side) is out of the possible use range or belt is damaged, replace drive belt.
Tension AdjustmentBLS00091
Belt tensioning is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Changing Engine CoolantBLS00092
WARNING:

To avoid being scalded, do not change engine coolant when engine is hot.

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

Be careful not to allow engine coolant to contact drive belt.
DRAINING ENGINE COOLANT
1. Remove grommet from undercover.
2. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.

When drain all of engine coolant in the system, open water drain plug on engine cylinder block.
Refer to EM-81, "
CYLINDER BLOCK" .
3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to MA-18, "
FLUSHING COOLING SYSTEM" .
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 water drain plug on cylinder block is removed, close and tighten it. Refer to EM-81, "
CYLINDER
BLOCK" .
2. Make sure that each hose clamp has been firmly tightened.
3. Remove air duct assembly. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
4. Disconnect heater hose (left side of vehicle) at the position in
the figure.

Enhance heater hose as high as possible.
5. Fill radiator and reservoir tank to specified level.

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

Use NISSAN Genuine Engine Coolant or equivalent
mixed with water (distilled or demineralized). Refer to
MA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS".

When engine coolant overflows disconnected heater hose, connect heater hose, and continue filling the
engine coolant.
6. Install air duct assembly. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
7. Install radiator cap.Radiator drain plug:
