drain bolt SUZUKI GRAND VITARA 1987 Service Repair Manual

CAUTION:
When changing engine coolant, use mixture
of 56% water and 50% GOLDEN CRUISER
1200for the market where ambient tem-
perature falls lower than -16°C (3°F) in
winter and mixture of 70% water and
30% GOLDEN CRUISER 1200for the
market where ambient temperature doesn’t
fall lower than -16°C (3” F).
Even in a market where no freezing tempe-
rature is anticipated, mixture of 70% water
and 30% GOLDEN CRUISER 1200
should be used for the purpose of corro-
sion protection and lubrication.

WARNING:
To avoid danger of being burned, do not
touch exhaust system when system is hot.
Any service on exhaust system should be
performed when system is cool.
When carrying out periodic maintenance, or the
car is raised for other service, check exhaust
system as follows:
l Check rubber mountings for damage, deterio-
ration, and out of position.
l Check exhaust system for leakage, loose
connections, dents, and damages.
If bolts or nuts are loose, tighten them to
specification. Refer to below chart for torque
specification.
l Check nearby body areas for damaged, miss-
ing, or mispositioned parts, open seams,
holes, loose connections or’ other defects
which could permit exhaust fumes to seep
into the car.
l Make sure that exhaust system components
have enough clearance from the underbody to
avoid overheating and possible damage to the
floor carpet.
l Any defects should be fixed at once.

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.

(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.

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.

NOTE:
3) Remove distributor assembly.
l Observe critically before starting to remove a
component or part by loosening bolts, nuts
and the like. What you may find before and
during disassembly is valuable information
necessary for sucessful reassembly.
l Be careful in .handling aluminum-alloy parts.
They are softer than steel or cast-iron parts
and their finished surfaces more easily- take
scratch marks.
l Have trays and pans ready for setting aside
disassembled parts in an orderly manner.
Place parts in trays and pans in such a way_.
that they can be readily identified. Put matchFig. 3-4-3
marks or tags on them, as necessary, so that
they will go back to where they came from.
4) Remove the fuel pump and rod.
Carry out engine disassembly in the following
NOTE:
sequence :When removing pump and distributor gear case,
1) Loosen drain plug and drain out engine oil.place waste or receiver under gear casa.
