GENERAL PRECAUTIONS
1. Know the importance of periodic maintenance.
(a) Every service item in the periodic maintenance list
must be performed.
(b) Failing to item can cause the engine to run poorly
and increase exhaust emissions.
2. Listen to the customers comments carefully.
Always determine exactly what the customer complaint is,
if any, and verify it before proceeding with repairs.
3. Determine if you have an engine or emission system pro-
blem.
(a) Engine problems are usually not caused by the emis-
sion control systems.
(b) When troubleshooting, always check the engine and
the ignition system first.
4. Check hose and wiring connections first.
The most frequent cause of problems is simply a bad con-
nection in wiring or vacuum hoses. Always make sure that
connections are secure and correct.
5. Observe
the following precautions to avoid damage to the
parts:
(a) To disconnect vacuum hoses, pull on the end, not the
middle of the hose.
(b) To pull apart electrical connectors, pull on the con-
nector itself, not the wires.
(c ) Be careful not to drop electrical components, such as
sensors
or relays. If they are dropped on a hard floor,
they should be replaced and not reused.
(d) When steam cleaning an engine, protect the distri-
butor, coil, air filter, carburetor intake, air pump and
VCV from water.
(e) Never use an i
mpact wrench to remove or install
thermo switches or thermo sensors.
(f) When checking continuity at the wire connector,
insert
the tester probe carefully to prevent termi na ls
from bending.
(g) When using a vacuum gauge, never force the hose
onto a connector that is too larg e. Use a step-down
adapter instead. Once the hose has been stretched, it
may leak.

6. Tag hoses before disconnecting them:
(a) When disconnecting vacuum hoses, u se ta gs to identi·
fy how they shou ld be reconnected.
( b) After completing a job, double check that the vac-
uum hoses are properly connected. A label under the
hood shows the proper layout.
PRECAUTIONS FOR VEHICLES EQUIPPED WITH A
CATALYTIC CONVERTER
WARNING : If large amounts of unburned gasoline flow into
the catalytic co nverter, 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 fast idle speed for more than
10 minutes and an idle speed for more than 20 minutes.
3. Avoid spark
jump test .
(a) Spark jump only when absolutely necessary. Pe rform
this test
as rapidly as possible.
(bl While testi ng , never race the en gi ne.
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 .
Thi s may cause the engine to misfire and create an ext ra
load on the catalytic converter.
6. Avoid coasting
with ignition turned off and prolonged
braking.
7. Do
not dispose of used catalytic converter near parts co n·
taminated with gasoline or oil.

INTRODUCTION -General Repair Instructions
GENERAL REPAIR INSTRUCTIONS
1. Use fender seat and floor covers to keep the vehicle clean
and prevent damage.
2. During disassembly. keep parts
in order for reassembly.
3. Before performing electrical
or fuel work, disconnect the
negative (-) battery cable.
4. Check hose and wiring connectors
to make sure that they
are secure and correct.
5. Always replace gaskets and D-rings with new ones.
6. Always use sealer on gaskets
to prevent leaks.
7. Carefully observe all specifications for
bolt torques.
Always use a torque wrench.
8. Use of Special Service Tools (SST) may be required,
depending on the nature of the repair. Be sure to use the
SST where specified, and follow the proper work proce-
dure.
9_ Care must be taken when jacking up and supporting the
vehicle_ Be sure to lift and support the vehicle at the
proper locations_
(a ) If the vehicle is to be jacked up only at the front or
rear end, be sure
to block the wheels in order to

(b) Always use a hydraulic hoist or jack stand. It is
extremely dangerous
to work on a veh icle supported
