ABS TOYOTA CAMRY V20 1986 Service Information

6. Precoated parts
Precoated parts are bolts and nuts, etc. that are coated with a
seal lock adhesive at the factory.
(a) If a precoated part is retightened, loosened or caused to
move in any way, it must be recoated with the specified
adhesive.
(b) Recoating of precoated parts
(1) Clean off the old adhesive from the bolt, nut or threads.
(2) Dry with compressed air.
(3) Apply the specified sea! lock adhesive to the bolt or nut
threads.
(e) Precoated parts are indicated in the. component illustra-
tions by the ºrº symbol.
7. When necessary, use a sealer on gaskets to prevent leaks.
8. Carefully observe all specifications for bolt tightening torques. Al-
ways use a torque wrench.
9. Use of special service tools (SST) and special service materials
(SSM) may be required, depending on the nature of the repair.
Be sure to use SST and SSM where specified and follow the
proper work procedure. A list of SST and
SSM can be found at the back of this manual.
10. When replacing fuses, be sure the new fuse has the correct am-
perage rating. DO NOT exceed the rating or use one with a low-
er rating.
11. Care must be taken when jacking up and supporting the vehicle.
Be sure to lift and support the vehicle at the proper locations.
(See page IN±27)
(a) If the vehicle is to be jacked up only at the front or rear end,
be sure to block the wheels at the apposite end in order
to ensure safety.
(b) After the vehicle is jacked up, be sure to support it on stands.
It is extremely dangerous to do any work on a vehicle
raised on a jack alone, even for a small job that can be fin-
ished quickly.
12. Observe the following precautions 'to avoid damage to the parts:
(a) Do not open the cover or case of the ECU unless abso-
lutely necessary. (If the IC terminals are touched, the
IC may be destroyed by static electricity.)
(b) When replacing the internal mechanism (computer
part) of the digital meter, be careful that no
part of your body or clothing comes in contact with the
terminals of the leads from the IC, etc. of the replace-
ment part (spare part).
(c) To disconnect vacuum hoses, pull on the end, not the middle
of the hose.
M To pull apart electrical connectors, pull on the connector
itself, not the wires.
(e) Be careful not to drop electrical components, such as sen-
sors or relays. If they are dropped on a hard floor, they
should be replaced and not reused.

PRECAUTIONS FOR VEHICLES EQUIPPED WITH A
CATALYTIC CONVERTER
CAUTION: If large amounts of unburned gasoline flow into the converter, it may overheat
and create a fire hazard. To prevent this, observe the following precautions and
explain them to your customer.
1. Use only unleaded gasoline.
2. Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20
minutes.
3. Avoid spark jump test.
(a) Spark jump test only when absolutely necessary. Perform this test as rapidly as pos-
sible.
(b) While testing, never race the engine.
4. Avoid prolonged engine compression measurement.
Engine compression tests must be made as rapidly as possible.
5. Do not run engine when fuel tank is nearly empty.
This may cause the engine to misfire and create an extra
load on the converter.
6. Avoid coasting with ignition turned off and prolonged braking.
7. Do not dispose of used catalyst along with parts contaminated with gasoline or oil.(f) When steam cleaning an engine, protect the distribu-
tor, air filter and VCV from water.
(g) Never use an impact wrench to remove or install tem-
perature switches or temperature sensors.
(h) When checking continuity at the wire connector, insert
the tester probe carefully to prevent terminals from
bending.
(i) When using a vacuum gauge, never force the hose
onto a connector that is too large. Use a step±down
adapter instead. Once the hose has been stretched,
it may leak.
13. Tag hoses before disconnecting them:
(a) When disconnecting vacuum hoses, use tags to iden-
tify how they should be reconnected.
(b) After completing a job, double check that the vacuum
hoses are properly connected. A label under the
hood shows the proper layout.

REAR WHEEL ALIGNMENT
1. MAKE FOLLOWING CHECKS AND CORRECT ANY
PROBLEMS
(a) Check the tires for wear, size and proper inflation
pressure.
Cold tire inflation pressure:
FWD/SV21 and 4WD 2.1 kg/cm2 (30 psi, 206 kPa)
FWD/VZV21 1.9 kg/cm2 (27 psi, 186 kPa)
(b) Check the front wheel bearings for looseness.
(e) Check the wheel runout.
Lateral runout: Less than 1.0 mm (0.039 in.)
(d) Check the front suspension for looseness.
(e) Check that the front shock absorber function properly
by using the standard bounce test.
If the clearance of the vehicle is not standard try to
level by locking it down. If still not correct, check
for bad springs or suspension parts.
HINT: Before inspecting wheel alignment, adjust
chassis ground clearance to specification. 2. MEASURE CHASSIS GROUND CLEARANCE
Chassis ground clearance: m m (in.)
