checking oil NISSAN PATROL 2006 Service Manual

Checking Brake Fluid Level
+Check ¯uid level in reservoir tank. It should be between Max
and Min lines on reservoir tank.
+ If ¯uid level is extremely low, check brake system for leaks.
+ If the brake warning lamp comes on, check brake ¯uid level
switch and parking brake switch.
Checking Brake Line
CAUTION:
If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.
1. Check brake lines (tubes and hoses) for cracks, deterioration
or other damage. Replace any damaged parts.
2. Check for oil leakage by fully depressing brake pedal while engine is running.
Changing Brake Fluid
CAUTION:
+Re®ll with new brake ¯uid ``DOT 3''.
+ Always keep ¯uid level higher than minimum line on res-
ervoir tank.
+ Never reuse drained brake ¯uid.
+ Be careful not to splash brake ¯uid on painted areas; it
may cause paint damage. If brake ¯uid is splashed on
painted areas, wash it away with water immediately.
1. Clean inside of reservoir tank, and re®ll with new brake ¯uid.
2. Connect a vinyl tube to each air bleeder valve.
3. Drain brake ¯uid from each air bleeder valve by depressing brake pedal.
4. Re®ll until brake ¯uid comes out of each air bleeder valve. Use same procedure as in bleeding hydraulic system to re®ll
brake ¯uid. Refer to ``Bleeding Brake System'', BR-4.

19. Pack drive ¯ange groove with grease, apply grease to O-ring
and mating surface of drive ¯ange, and install ¯ange.
20. Place snap ring in drive shaft groove. Choose snap ring so that
the gap between groove and snap ring is 0.4 mm (0.016 in) or
less.
Refer to SDS for selection of snap ring.
Front Wheel Alignment
Before checking front wheel alignment, be sure to make a prelimi-
nary inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand
tools and mats in designated positions.
PRELIMINARY INSPECTION
1. Check tires for wear and improper in¯ation.
2. Check wheel runout on outside and inside.
Wheel runout average
[(Outside runout value + Inside runout value) x 0.5]:
Refer to SDS (FA-27).
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that shock absorbers work properly.
7. Check vehicle posture (Unladen).
CAMBER, CASTER AND KINGPIN INCLINATION
Camber, caster and kingpin inclination are preset at factory
and cannot be adjusted.
1. Measure camber, caster and kingpin inclination of both right
and left wheels with a suitable alignment gauge.
Camber, Caster and Kingpin inclination:
Refer to SDS (FA-27).
2. If camber, caster or kingpin inclination is not within
speci®cation, inspect front suspension parts. Replace damaged
or worn out parts.

Precautions for Three Way Catalyst
(If so equipped)
If a large amount of unburned fuel ¯ows into the catalyst, the cata-
lyst temperature will be excessively high. To prevent this, follow the
instructions below:
+Use unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
+When checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
+Do not run engine when the fuel tank level is low, otherwise the
engine may mis®re causing damage to the catalyst.
Do not place the vehicle on ¯ammable material. Keep ¯ammable
material off the exhaust pipe and the three way catalyst.
Precautions for Engine Oils
Prolonged and repeated contact with used engine oil may cause
skin cancer. Try to avoid direct skin contact with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner
as soon as possible.
HEALTH PROTECTION PRECAUTIONS
+Avoid prolonged and repeated contact with oils, particularly
used engine oils.
+Wear protective clothing, including impervious gloves where
practicable.
+Do not put oily rags in pockets.
+Avoid contaminating clothes, particularly underpants, with oil.
+Heavily soiled clothing and oil-impregnated footwear should not
be worn. Overalls must be cleaned regularly.
+First Aid treatment should be obtained immediately for open
cuts and wounds.
+Use barrier creams, applying them before each work period, to
help the removal of oil from the skin.
+Wash with soap and water to ensure all oil is removed (skin
cleansers and nail brushes will help). Preparations containing
lanolin replace the natural skin oils which have been removed.
+Do not use gasoline, kerosine, diesel fuel, gas oil, thinners or
solvents for cleaning skin.
+If skin disorders develop, obtain medical advice without delay.
+Where practicable, degrease components prior to handling.
+Where there is a risk of eye contact, eye protection should be
worn, for example, chemical goggles or face shields; in addition
an eye wash facility should be provided.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Burning used engine oil in small space heaters or boilers can be
recommended only for units of approved design. The heating sys-
tem must meet the requirements of HM Inspectorate of Pollution for
small burners of less than 0.4 MW. If in doubt check with the
appropriate local authority and/or manufacturer of the approved
appliance.
