1987 SUZUKI GRAND VITARA oil level

4. ENGINE OIL AND FILTER CHANGEBefore draining engine oil, check engine for oil
leakage. If any evidence of leakage is found,
make sure to correct defective part before
proceeding to the following work.
1) Drain engine oil by removing drain plug.
2) After draining oil, wipe drain plug clean.
Reinstall drain plug, and tighten it securely.

3) Loosen oil filter by using oil filter wrench
“A” (special tool 09915-47310).
4) Screw new filter on oil filter stand by hand
until the filter “0” ring contacts the mounting
surface.
ICAUTION:
To tighten the oil filter properly, it is important to accurately identify the
1-position at which the filter “0” ring first
contacts the mounting surface.
5)Tighten the filter 3/4 turn from the point of
contact with the mounting surface using an

6) Replenish oil until oil level is brought to
FULL level mark on dipstick. (about 3.7liters or 7.8/6.5

US/Imp pt.). The filler
inlet is atop the cylinder head cover.
7) Start engine and run it for three minutes.
Stop engine and wait another three minutes
before checking oil level. Add oil, as necessary,
to bring oil level to FULL level mark on dip
stick.
NOTE:
Before fitting new oil filter, be sure to oil its
“0” ring. Use engine oil for this purpose.

flange yoke bolts for tightness, and retighten
them as necessary:

42. TRANSMISSION, TRANSFER,
DIFFERENTIAL OIL INSPECTION
AND CHANGE
[I nspectionl
1) Inspect transmission case, transfer case and
differential housing for evidence of oil leakage.
Repair leaky point if any.
2) Make sure that the car is placed level for oil
level check.
3) Remove each level plug of transmission,
transfer and differential (front and rear).
In any of these cases, oil level can be checked
roughly by means of level plug hole. That is,
,if oil flows out of level plug hole or if oil
level is found up to hole when level plug is
removed, oil is properly filled.
If oil is found insufficient, pour specified
amount of specified oil as given in the below
table.
[Change]
Oil change procedure is as follows.
Place the car level and drain oil by removing
drain plug. Pour specified amount of specified
oil as in the below table and tighten drain plug
and filler plug to specified torque.
It is highly recommended to use SAE 75W-90
gear oil.

43. LEAF SPRING lNSPECTlON
Check leaf spring for wear, crack and damage.
(Where each end of the shorter leaf contacts.)
If excessive wear of cracking is noted, replace
the spring with a new one.
44. BOLTS AND NUTS TIGHTENING
Check suspension bolts and nuts for tightness
and retighten them as necessary.
Repair or replace defective parts, if any.
NOTE:
For the details of check points, refer to the
table of MAINTENANCE SERVICE (p. 17-24)
of SECTION 17.
45. STEERING SYSTEM INSPECTION
1) Check steering wheel for play and rattle,
holding car in straight forward condition on
the ground.
Steering wheel play10 - 30 mm
(0.4 - 1.2 in.)
3) Check bolts and nuts for tightness and retigh-
ten them as necessary. Repair or replace
defective parts, if any.
Refer to MAINTENANCE SERVICE on p.
18-18 for particular check points.
4) Inspect steering gear box for evidence of oil
leakage. If leakage is found, check oil level
in gear box.
NOTE:
For the details of the above steps 1) to 41, refer
to MAINTENANCE SERVICE (p. 18-18) of
SECTION 18.
.5) Check boots of tie rod ends for damage. If
damage is found, replace it with a new one.
6) Check wheel alignment.

Lubricate door hinges for smooth operation.
2) Check universal joint and rubber joint of
steering shaft for rattle and damage. If rattle
or damage is found, replace defective part
with a new one.
