2004 NISSAN TERRANO check engine

Checking Fluid Leakage
Check the lines for improper attachment and for leaks, cracks,
damage, loose connections, chafing or deterioration.
1. Run engine between idle speed and 1,000 rpm.
Make sure temperature of fluid in oil tank rises to 50 to 80ÉC
(122 to 176ÉF).
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each ªlockº position for five seconds andcarefully check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 10 seconds (There is possibility that oil pump may be
damaged.).
4. If fluid leakage at connectors is noticed, loosen flare nut and then retighten.
Do not overtighten connector as this can damage O-ring,
washer and connector.
5. If fluid leakage at the connectors are noticed, then loosen the flare nut and retighten it.
Bleeding Hydraulic System
1. Raise front end of vehicle until wheels are clear of the ground.
2. Add fluid into oil tank to specified level. Meanwhile quickly turnsteering wheel fully to right and left and lightly touch steering
stoppers.
Repeat steering wheel operation until fluid level no longer
decreases.
3. Start engine. Repeat step 2 above.
I Incomplete air bleeding will cause the following to occur. When
this happens, bleed air again.
a. Generation of air bubbles in reservoir tank
b. Generation of clicking noise in oil pump
c. Excessive buzzing in oil pump
While the vehicle is stationary or while moving the steering wheel
slowly, fluid noise may occur in the valve or oil pump. This noise is
inherent in this steering system, and it will not affect performance
or durability of the system.

Checking Steering Wheel Turning Force
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating tempera-ture.Temperature: 50É - 80ÉC (122 - 176ÉF)
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has been turned 360É from neutral position.Steering wheel turning force: 39 N (4 kg, 9 lb) or less
I If steering wheel turning force is not within specification,
perform the following inspection procedure:

Checking Hydraulic System
Before starting, check belt tension, driving pulley and tire pressure.
1. Set Tool. Open shut-off valve, then bleed air. (Refer to ªBleed-ing Hydraulic Systemº, ST-5.)
2. Run engine.
Make sure temperature of fluid in tank rises to 60 to 80ÉC (140
to 176ÉF).
WARNING:
Warm up engine with shut-off valve fully opened. If engine is
started with shut-off valve closed, oil pressure in oil pump will
increase to relief pressure, resulting in an abnormal rise in oil
temperature.
3. Check pressure with steering wheel fully turned to left and right positions with engine idling at 1,000 rpm.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds. Oil pump maximum standard pressure:TD27Ti engine8,800 - 9,200 kPa (88 - 92 bar,
89 - 93 kg/cm
2, 1,276 - 1,334 psi)
ZD30DTi engine 9,800 - 10,500 kPa (98.0 - 105.0 bar,
99.96 - 107.10 kg/cm
2, 1,421 - 1,523 psi)
4. If oil pressure is below the maximum pressure, slowly close shut-off valve and check pressure.
I When pressure reaches maximum pressure, gear is damaged.
I When pressure remains below maximum pressure, pump is
damaged.
CAUTION:
Do not close shut-off valve for more than 15 seconds.
5. If oil pressure is higher than maximum pressure, check oil pump flow control valve.
6. After checking hydraulic system, remove Tool and add fluid if necessary, then completely bleed air out of system.NST033

Panel joint
Side sill of rear fender and center pillar, rear wheel housing of rear fender, around strut tower in engine
compartment, etc.
Panel edge
Back door opening, sunroof opening, fender wheelarch flange, fuel filler lid flange, around holes in panel, etc.
Parts contact
Waist molding, windshield molding, bumper, etc.
Protectors
Damage or condition of mudguard, fender protector, chipping protector, etc.
Anti-corrosion materials
Damage or separation of anti-corrosion materials under the body.
Drain holes
Condition of drain holes at door and side sill.
When repairing corroded areas, refer to the Corrosion Repair Manual.

Precautions for Servicing Compressor
IAttach a blind plug to the suction port (low pressure) and discharge port (high pressure) of the
compressor to prevent oil from leaking out and dust from getting inside.
I When the compressor is removed, store it under the same condition as it is when mounted on the
car.
I When replacing or repairing compressor, be sure to remove oil from the compressor and check
the oil quantity extracted.
I When replacing with a new compressor, be sure to remove oil from the new compressor so that
the quantity of oil remaining in the new compressor is equal to the quantity collected from the
removed compressor. See the section ªLUBRICATION OILº.
I Pay attention so as not to allow dirt and oil to attach on the friction surfaces between clutch and
pulley. If the surface is contaminated, with oil, wipe it off by using a clean waste cloth moistened
with thinner.
I After completing the compressor service operation, be sure to rotate the compressor shaft more
than five turns in both directions by hand to equalize oil distribution inside the compressor, then
run the compressor for about one hour by idling the engine.
I When the compressor magnet clutch has been replaced, be sure to check the magnet clutch for
normal operation by applying voltage to the clutch.

Lubrication Oil
Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
Maintenance of Oil Quantity in Compressor
The oil used to lubricate the compressor circulates through the
system with the refrigerant. Whenever any component of the sys-
tem is replaced or a large amount of gas leakage occurs, add oil
to the compressor to maintain the specified amount.
If oil quantity is not maintained properly, the following malfunctions
may result:
ILack of oil: May lead to a seized compressor
I Excessive oil: Inadequate cooling (thermal exchange impeded)
Checking and Adjusting
Adjust the oil quantity according to the flowchart shown below.

Operation Check
The purpose of the operational check is to confirm that the system
is as it should be. The systems which will be checked are the
blower, mode (discharge air), intake air, temperature decrease,
temperature increase and A/C switch system.
CONDITIONS:
Engine running and at normal operating temperature.
PROCEDURE:
1. Check blower
1) Turn FAN CONTROL DIAL to 1.Blower should operate at speed 1.
2) Then turn the DIAL to speed 2.
3) Continue checking blower speed until all speeds are checked.
4) Leave blower on speed 4.
2. Check discharge air
1) Turn AIR CONTROL DIAL toposition.
2) Confirm that all discharge air comes out of face vents.
3) Turn AIR CONTROL DIAL to
position.
4) Confirm that discharge air comes out of face vents and foot vents.
5) Turn AIR CONTROL DIAL to
position.
6) Confirm that discharge air comes out of foot vents, with some air from face vents.
7) Turn AIR CONTROL DIAL to
position.
8) Confirm that discharge air comes out of foot vents with some air from defroster vents.
9) Turn AIR CONTROL DIAL to
position.
10) Confirm that all discharge air comes out of defroster vents, with some air from face vents.
3. Check recirculation
1) Switch AIR RECIRCULATION SWITCH to ON position (Indica-tor light ON).
2) Listen for intake door position change (you should hear sound change slightly).
