BASIC ASSUMPTIONS
This workshop manual assumes that you have certain special tools that are necessary for the safe and effi-
cient performance of service operations on Mazda vehicles and that you know how to use
them properly.
It also assumes that you are familiar with automobile
systems and basic service and repair procedures. You
should
not attempt to use this manual unless these assumptions are correct and you understand the conse-
quences described below.
SAFETY RlSK
This manual contains certain notes, warnings, and other precautionary information that you should carefully
read and follow to reduce the risk of personal injury to yourself or others and the risk of improper service
that may damage the vehicle
or render it unsafe. If there is no such information in regard to any specific
service method, this does not mean there is no possibility that personal safety or vehicle safety will be
jeopardized by the use of incorrect methods or toots.
POSSIBLE LOSS OF WARRANTY
The manufacturer’s warranty on Mazda vehicles and engines can be voided if improper service or repairs
are performed by persons other than those at an Authorized Mazda Dealer.
WARNING ON LUBRICANTS AND GREASES ’
Avoid all prolonged and repeated contact with mineral oils, especially used oils. Used 08s contaminated
during service (e.g., engine sump oils) are more irritating and more likely to cause serious effects, including
skin cancer, in the event of gross and prolonged skin contact.
Wash skin thoroughly after work involving oil.
Protective hand cleaners may be of value provided they can be removed from the skin with water. Do not
use gasoline, paraffin, or other solvents to remove oil from the skin.
Lubricants and greases may be slightly irritating to the eyes.
Repeated or prolonged skin contact should be avoided by wearing protective clothing if necessary. Particu-
lar care should be taken with used oils and greases containing lead. Do not allow work clothing to be con-
taminated with oil. Dry clean or launder such clothing at regular intervafs.

REPAIR PROCEDURE I.
Most repair operations begin with an overview illustration. It identifies the components, shows how the
parts fit together, and visual parts inspections. If a
damaged or worn part is found, repair or replace it
as necessary.
2. Expendable parts, tightening torques, and symbols for oil, grease, and sealant are shown in the overview
iItustration.
3. Pages related to service procedures are shown under the illustration. Refer to this information when ser-
vicing the related part.

ELECTRICAL TROUBLESHOOTING TOOLS
Test Light
The test light, as shown in the figure, uses a f2V bulb. The
two lead wires should be connected to
probes.
The test light is used for simple voltage checks and for check-
ing for short circuits.
Caution
l When checking the control unit, never use a butt,
over 3.4w.
Jumper Wire
The jumper wire is used for testing by shorting across switch
terminals and ground connections.
Caution
l Do not connect a jumper wire from the power source
, line to a body ground; this may cause burning or
other damage to harnesses or electronic com-
ponents. -
Voltmeter
The DC voltmeter is used to measure of circuit
voltage. A volt-
meter with a range of 15V or more is used by connecting the
positive ( + ) probe (red lead wire) to the point where voltage
is to be measured and the negative (-1 probe (black lead
wire) to a body ground.
Diagnosis Connector
Insert the probe into the service hole when connecting a jum-
per wire to the diagnosis connector.
Caution
l Do not insert the jumper wire probe into the diag-
nosis connector terminal, which may damage the
terminal.
Ohmmeter
The ohmmeter is used to measure the resistance between two
points in a circuit and atso to check for continuity and diagno-
sis of short circuits.
Caution
l Do not attempt to connect the ohmmeter to any cir-
cuit to which voltage is applied; this may burn or
otherwise damage the ohmmeter.

If the vehicfe is operated under the foltowing conditions, it is suggested that
the engine oil and oil f&r
be changed more often that at usual recommended intervals.
a> Driving in dusty condrt,ons.
b) Extended periods of idling
or low speed operation.
c) Driving for a prolonged period iti coid temperatures or driving only short distances regularly.
Replacement of the timing belt is required at every 105,000 km. failure to replace the timing belt may
result in damage to the engine.

than at usual recommended intervals.
Adjust or inspect alternator and water pump drive belt, and power steering and air conditioner drive belt
if equipped.
Replace every two years.
If there has been continuous hard driving, mountain driving, or if the brakes are used extensively or the
vehicle is operated in extremely humid climates, the brake fluid shotlid be changed annually.
Emission Control and Related Systems
The ignition and fuel systems are vitally important to the proper operation of the emission control and related
system, as well as for efficient engine operation. It is strongly recommended that all servicing related to these
systems be done by your Authorised Mazda Dealer.
