1987 SUZUKI GRAND VITARA torque

5. Fig. O-7 and O-8 show how to lift the car by
using a hoist.
WARNING:
l When using frame contact hoist, apply
hoist as shown below (right and left at
the same position), Lift up the car till 4
tires are a little off the ground and make
sure that the car will not fall off by try-
ing to move car body in both ways. Work
can be started only after this confirma-
tion.
l Before applying hoist to underbody,
always take car balance throughout serv-
ice into consideration. Car balance on
hoist may change depending of what
part to be removed.
lFor suspention parts removal, follow pre-
vious steps 3 and 4.
l Make absolutely sure to lock hoist after
car is hoisted up.
When using frame contact hoist:
6. Orderliness is a key to successful overhauling.
Trays, pans and shelves are needed to set
aside disassembled parts in groups or sets
in order to avoid confusion and misplace-
ment. This is particularly important for
engine overhauling.
7. Have on hand liquid packing-SUZUKI
BOND No. 1215 (99000-31110) - for
ready use. This packing dope is an essential
item to assure leak-free (water and oil) work-
manship.
8. Each bolt must be put back to where it was
taken from or for which it is intended. Do
not depend on your hunch in tightening
bolts for which tightening torque values are
specified: be sure to use torque wrenches on
those bolts.
9. It is advisable to discard and scrap gaskets
and “0” rings removed in disassembly. Use
new ones in reassembly, and try not to
econimize gaskets and “0” rings.
10. Use of genuine SUZUKI parts is imperative.
Use of imitation parts is a big gamble on
safetyand performance. Use genuine
SUZUKI parts and live up to the trust your
customer places on you.
11. Special tools save time and ensure good
workmanship: They are available from
SUZUKI. Use them where their use is
specified. Moreover, your own safety is
assured by the use of special tools in many
of the disassembly and reassembly steps.

STANDARD TIGHTENING TORQUE
Each fastener should be tightened to the torque specified in each section of this manual. If no description
or specification is provided, refer to the following tightening torque chart for the applicable torque for
each fastener. When a fastener of greater strength than the original one is used, however, use the torque
specified for the original fastener.
NOTE:
l For the flanged bolt and nut, add 10% to the tightening torque given in the below chart
l The below chart is applicable only where the fastened parts are made of steel or light alloy.

“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.

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.

perature.
3) Connect CO tester to mufler tail pipe.
4) With the engine warmed up, keep the engine
speed at 1,500 to 2,000 r/min. (t-pm). If the
CO concentration is 0.4% or less in this state,
the catalytic converter is in good condition.
If it exceeds the specification, refer to DIA-
GNOSIS (p. 5-15).

31. BRAKE DISCS, PADS, BRAKE DRUMS
AND SHOES INSPECTION
Brake Discs and Pads
I) Remove wheel and caliper but don’t discon-
nect brake hose from caliper.
2) Check front disc brake pads and discs for
excessivewear,damageand deflection.
Replace parts as necessary. For the details,
refer to p. 19-I 6 and 19-I 7 of SECT ION 19.
Be sure to torque caliper guide pins to specifi-
cation for reinstallation.
Brake Drums and Shoes
I) Remove wheel and brake drum.

22 of SECTION 19.
32. BRAKE HOSES AND PIPES INSPECTION
Check brake hoses and pipes for proper hook-
up, leaks, cracks, chafing and other damage.
Replace any of these parts as necessary.
CAUTION:
After replacing any brake pipe or hose, be
sure to carry out air purge operation.
33. BRAKE FLUID INSPECTION AND
CHANGE
[INSPECTION]
1) Check around master cylinder and reservoir
for fluid leakage.
If found leaky, correct.
2) Check fluid level
If fluid level is lower than the minimum level
of reservoir, refilling is necessary. Fill reservoir
with specified brake fluids.
Brake fluid Speifi;t3ons
For the details, refer to MAINTENANCE
SERVICE (p. 19-42) of SECTION 19.
CAUTION:
Since the brake system of this car is factory-
filled with glycol-base brake fluid, do not
use or mix different type of fluid when
refilling the system; otherwise serious
damage will occur. Do not use old or used
brake fluid, or one taken from unsealed
container.
[CHANGE]
1) Change brake fluid. As fluid change procedure,
drain existing fluid from brake system com-
pletely, fill the system with above recom-
mended fluid and carry out air purge opera-
tion.
For description of air purge, refer to p. 19-46
and 19-47 of SECTION 19.
34. BRAKE PEDAL INSPECTION
Check brake pedal travel.
For -checking procedure, refer to PEDAL TRA-
VEL CHECK (p. 19-43) of SECTION 19.
35. BRAKE LEVER AND CABLE
INSPECTION

I) Check tooth tip of each notch for damage or
wear. If any damage or wear is found, replace
parking lever.
2) Check parking brake lever for proper opera-
tion and stroke, and adjust it if necessary.
For checking and adjusting procedures,
refer to PARKING BRAKE INSPECTION
