REFRIGERATION SYSTEM SYMPTOMS
Trouble Diagnosis For Unusual PressureINFOID:0000000009463923
Diagnose using a manifold gauge whenever system’s high and/or low side pressure(s) is/are unusual. The
marker above the gauge scale in the following tables indicates the standard (usual) pressure range. Refer to
above table (Ambient air temperature-to-operating pres sure table) since the standard (usual) pressure, how-
ever, differs from vehicle to vehicle.
Symptom TableINFOID:0000000009463924
Gauge indication Refrigerant cycle Probable cause Corrective action
Both high and low pressure sides
are too high. The pressure returns to nor-
mal soon after sprinkling wa-
ter on condenser. Overfilled refrigerant. Collect all refrigerant, evacuate
refrigerant cycle again, and
then refill it with the specified
amount of refrigerant.
Air flow to condenser is insuf-
ficient. Insufficient condenser cooling
performance.
• Poor fan rotation of radiator and condenser.
• Improper installation of air
guide.
• Clogged or dirty condenser fins. • Repair or replace malfunc-
tioning parts.
• Clean and repair condenser
fins.
When compressor is stopped,
a high-pressure reading
quickly drops by approximate-
ly 196 kPa (2 kg/cm
2, 28 psi).
It then gradually decreases. Air mixed in refrigerant cycle.
Collect all refrigerant, evacuate
refrigerant cycle again, and
then refill it with the specified
amount of refrigerant.
• Low-pressure pipe is cooler than the outlet of evapora-
tor.
• Low-pressure pipe is frost- ed. Expansion valve opened too
much (excessive flow of refrig-
erant). Replace expansion valve.
High-pressure side is excessively
high and low-pressure side is too
low.
High-pressure pipe and upper
side of condenser become
hot, however, liquid tank does
not become so hot. Clogged or crushed high-pres-
sure pipe located between
compressor and condenser. Repair or replace the malfunc-
tioning parts.
High-pressure side is too low and
low-pressure side is too high. • The readings of both sides
become equal soon after
compressor operation
stops.
• There is no temperature dif- ference between high- and
low-pressure sides. Malfunction in compressor sys-
tem (insufficient compressor
pressure operation).
• Damage or breakage of
valve.
• Malfunctioning gaskets. Replace compressor.

1. Loose harness or harness connectors.
2. Front console map/reading lamp lens loose.
3. Loose screws at console attachment points.
SEATS
When isolating seat noise it's important to note the pos ition the seat is in and the load placed on the seat when
the noise is present. These conditions should be dupl icated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of thes e incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component installed to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator installation pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine rpm or
load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

GENERAL MAINTENANCE
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically (e.g. each time you check the engine oil or refuel).
SeatsCheck seat position controls such as seat adjusters, seatback recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every po-
sition. Check that the head restrains move up and down smoothly and that the
locks (if equipped) hold securely in all latched positions. Check that the latches
lock securely for folding-down rear seatbacks. —
Seat belts Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly, and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage. SB-5, "Inspection"
Accelerator pedal
Check the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal. —
Brakes Check that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
booster Check the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Be sure to keep
the floor mats away from the pedal. BR-48
,
BR-49
Parking brake Check that the pedal has the proper travel and make sure that the vehicle is held
securely on a fairly steep hill when only the parking brake is applied. PB-4
CVT P (Park) position
mechanism On a fairly steep hill check that the vehicle is held securely with the shift selector
in the P (Park) position without applying any brakes. —

Windshield washer
fluid Check that there is adequate fluid in the tank. —
Engine coolant level Check the coolant level when the engine is cold. MA-14
(QR25DE)
MA-23
(VQ35DE)
Radiator and hoses Check the front of the radiator and clean off any dirt, insects, leaves, etc., that
may have accumulated. Make sure the hoses have no cracks, deformation, de-
terioration or loose connections. —
Brake and clutch fluid
levels Make sure that the brake and clutch fluid levels are between the “MAX” and “MIN”
lines on the reservoir. MA-41
Battery
Check the fluid level in each cell. It should be between the “MAX” and “MIN” lines.
Vehicles operated in high temperatures or under severe conditions require fre-
quent checks of the battery fluid level. —
Engine drive belts Make sure that no belt is frayed, worn, cracked or oily. MA-13
(QR25DE)
MA-22
(VQ35DE)
Engine oil level Check the level on the oil level gauge after parking the vehicle on a level spot and
turning off the engine. MA-17
(QR25DE)
MA-26
(VQ35DE)
Power steering fluid
level and lines Check the level when the fluid is cold, with the engine off. Check the lines for im-
proper attachment, leaks, cracks, etc. MA-44
Exhaust system
Make sure there are no loose supports, cracks or holes. If the sound of the ex-
haust seems unusual or there is a smell of exhaust fumes, immediately locate the
trouble and correct it. MA-31
Underbody
The underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these sub-
stances, otherwise rust will form on the floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean those areas where mud and dirt
can easily accumulate. —
Fluid leaks Check under the vehicle for fuel, oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping from the air conditioner after use is
normal. If you should notice any leaks or gasoline fumes are evident, check for
the cause and correct it immediately. —

RECOMMENDED FLUIDS AND LUBRICANTS
FOR USA AND CANADA : Engi ne Coolant Mixture Ratio
INFOID:0000000009464538
The engine cooling system is filled at the factory with a pre-diluted mixture of 50% Genuine NISSAN Long Life
Antifreeze/Coolant (blue) and 50% water to provide year-round anti-freeze and coolant protection. The anti-
freeze solution contains rust and corrosion inhibitors. Additional engine cooling system additives are not nec-
essary.
WARNING:
• Do not remove the radiator or coolant reservoir cap wh en the engine is hot. Wait until the engine and
radiator cool down. Serious burns could be caused by high pressure fluid escaping from the radia-
tor.
• The radiator is equipped with a pressure type radiator cap. To prevent engine damage, use only a
genuine NISSAN radiator cap.
CAUTION:
• When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Antifreeze/Cool-
ant (blue) or equivalent. Genuine NISSAN Long Life Antifreeze/Coolant (blue) is pre-diluted to pro-
vide antifreeze protection to -34°F (-37°C). If additional freeze protection is needed due to weather
where you operate your vehicle, add Genuine NISS AN Long Life Antifreeze/Coolant (blue) concen-
trate following the directions on the container. If an equivalent coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) is used, follow the coolant manufacturer’s instructions to main-
tain minimum antifreeze protection to -34°F (-37°C). The use of other types of coolant solutions other
than Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent may damage the engine
cooling system.
• Mixing any other type of coolant other than Genu ine NISSAN Long Life Antifreeze/Coolant (blue),
including Genuine NISSAN Long Life Antifreeze/Coolant (green), or the use of non-distilled water will
reduce the life expectancy of the factory-fill coolant.

CHECKING RESERVOIR LEVEL
• Check if the reservoir tank coolant level is within MIN to MAX when the engine is cool.
• Adjust coolant level if it is too much or too little.
ENGINE COOLANT : Changing Engine CoolantINFOID:0000000009464545
WARNING:
• To avoid being scalded, do not change the coolant when the engine is hot.
• Wrap a thick cloth around cap and carefully remove the cap. First, turn the cap a quarter of a turn to
release built-up pressure. Then push down and turn the cap all the way to remove.
DRAINING ENGINE COOLANT
1. Remove the engine under cover. Refer to EXT-17, "Removal and Installation".
2. Open the radiator drain plug at the bottom of the radi ator and remove the radiator filler cap. This is the
only step required when partially draining the cooling system (radiator only).
CAUTION:
• Do not allow the coolant to contact the drive belt.
• Perform this step when engine is cold.
3. Follow this step for heater core removal/replac ement only. Disconnect the upper heater hose at the
engine side and apply moderate air pressure [103.46 kPa (1.055 kg/cm
2, 15 psi) maximum air pressure]
into the hose for 30 seconds to blow t he excess coolant out of the heater core.
4. When draining all of the coolant in the system, re move the reservoir tank and drain the coolant, then clean
the reservoir tank before installation.
CAUTION:
• Do not allow the coolant to contact the drive belt.
• Perform this step when engine is cold.
5. When draining all of the coolant in the system for engine removal or repair, open the drain plugs (A and B) on the cylinder
block.
