1987 SUZUKI GRAND VITARA oil pressure

NOTE:
Steps 1) - 6) outlined above must be performed
with ENGINE NOT RUNNING. For step 7),
be sure to have adequate ventilation while
engine is running
It is recommended to use engine oil of SE or
SF class.
NOTE:For temperatures below
32”F(O”C), it is highly
recommended to use SAE 5W-30 oil.

8) Check oil filter and drain plug for oil leakage.
5. COOLING SYSTEM HOSES AND
CONNECTIONS INSPECTION
1) Visually inspect cooling system hoses for any
evidence of leakage and cracks. Examine them
for damage, and check connection clamps
for tightness.
2) Replace all hoses which show evidence of
leakage, cracks or other damage. Replace all
clamps which cannot maintain proper tight-
ness.
6. ENGINE COOLANT CHANGE
WARNING:
To help avoid danger of being burned, do
not remove radiator cap while engine and
radiator are still hot. Scalding fluid and
steam can be blown out under pressure if
the cap is taken off too soon.
1) Remove radiator cap when engine is cool.
2) Loosen radiator drain plug @
to drain
coolant.
3) Remove reservoir tank 0, which is on the
side of radiator, and drain.
4) Tighten plug
@ securely. Also reinstall reser-
voir tank.

Parking Brake Cable
Inspect brake cable for damage and smooth
movement. Replace cable if it is in deteriorat-
ed condition.
36. TIRE INSPECTION AND ROTATION
1) Check tires for uneven or excessive wear, or
damage. If defective, replace.
2) Check inflating pressure of each tire and
adjust pressure to specification as necessary.
NOTE:
l Tire inflation pressure should be checked
when tires are cool.
l Specified tire inflation pressure should be
found on tire placard or in owners’ manual
which came with the car.
3) Rotate tires.
For the details of above steps 1) to 3), refer
to MAINTENANCE SERVICE (p. 18-19 and
18-20) of SECTION 18.
37. WHEEL DISCS AND FREE WHEELING
HUBS (if equipped) INSPECTION
Wheel Discs
Inspect each wheel disc for dents, distortion and
cracks. A disc in badly damaged condition must
be replaced.
Free Wheeling Hub
This is applicable to the car equipped with
free wheeling hubs.
Check free wheeling hub for proper operation
by moving free wheeling hub knob to LOCK
and FREE positions. (The same check on both
right and left wheels)
For checking procedure, refer to MAINTE-
NANCE SERVICE (p. 17-29) of SECTION 17.
38. STEERING KNUCKLE OIL SEAL
REPLACEMENT
For replacement procedure, refer to MAIN-
TENANCE SERVICE (p. 17-23) of SECTION
17.
39. WHEEL BEARING INSPECTION
[Inspection of wheel bearing]
1) Check front wheel bearing for wear, damage,
abnormal noise or rattles. For the details,
refer to MAINTENANCE (p. 17-20 and
17-21) of SECTION 17.
2) Check rear wheel bearing for wear, damage
abnormal noise or rattles. For the details,
refer to MAINTENANCE SERVICE (p. 17-24)
of SECTION 17.
[Inspection of front wheel bearing grease]
1) Remove wheel hub and spindle referring to
FRONT WHEEL HUB REMOVAL of SEC-
TION 17.
2) Check grease around front wheel bearing
rollars and between front axle shaft surface
and wheel spindle bush for deterioration and
capacity.
If grease is deteriorated, remove grease tho-
roughly and apply enough amount of new
SUZUKI SUPER GREASE A or wheel bearing
grease. If grease is found insufficient, add some
more.
1-18

3) Install spindle, bearings, wheel hub, bearing
nut and brake disc referring to INSTALLA-
TION (p. 17-12) of SECTION 17.
4) Adjust bearing preload and then tighten
bearing lock nut to specification. Refer to
MAINTENANCE (p. 17-21) of SECTION 17.
5) Install drive flange or free wheeling hub (if
equipped), brake caliper with mounting and
wheel referring to INSTALLATION (p. 17-
12) of SECTION 17.
For tightening torque of each bolt and nut,
refer to torque table (p. 17-26) of SECTION
17.
40. SHOCK ABSORBERS INSPECTION
1) Inspect absorbers for evidence of oil leakage,
dents or any other damage on sleeves; and
inspect anchor ends for deterioration.
2) Depending on the results of the above inspec-
tion, replace absorbers.
2
1. Shock absorber
2. Leaf spring
WARNING:
When handling rear shock absorber in
which high-pressure gas is sealed, make
sure to observe the following precautions.
1. Don’t disassemble it.
2. Don’t put it into fire.
3. Don’t store it where it gets hot
4. Before disposing it, be sure to drill a
hole in it where shown in the illustration
below and let gas and oil out. Lay it
down sideways for this work.
Drill hole with approx-imately 3 mm (0.12 in.)diameter.
Cover with a vinyl envelope asshown so that drill dust willnot scatter around.
41. PROPELLER SHAFTS INSPECTION AND
LUBRICATION
1) Lubricate propeller shaft,
The nipple for lubrication is located on each
sliding yoke. Be sure to use chassis grease.
2) Check universal joint and spline of propeller
shaft for rattle. If rattle is found, replace
defective part with a new one.
