00-l 6GENERAL - Precautions before Service
Caution
1. Before connecting or disconnecting the negative
cable, be sure to turn off the ignition switch and the
lighting switch.
(If this is not done,there is the possibility of
semiconductor parts being damaged.)
2.For MFI-equipped models, after completion of the
work steps [when the battery’s negative (-) termi-
nal is connected], warm up the engine and allow it
to idle for approximately five minutes under the
conditions described below, in order to stabilize
engine control conditions, and then check to be
sure that the idling is satisfactory.
Engine coolant temperature:
85-95X (185-203°F)
Lights, electric fans, accessories: OFF
Transaxle: neutral position (A/T models: “N” or
“P”)
Steering wheel:neutral (center) position

VEHICLE WASHING
If high-pressure car-washing equipment or steam car-washing
equipment is used to wash the vehicle, be sure to maintain the
spray nozzle at a distance of at least 300 mm (12 in.) from any plastic parts and all opening parts (doors, luggage compart-
ment, etc.).
SCAN TOOL (1) To operate the scan tool, refer to the “Scan Tool Operation Instructions”.
Connection and disconnection of the scan tool should
always be made with the ignition switch in the OFF
position.
(2) Always use a ROM pack that is appropriate for the vehicle.

If premium unleaded gasoltne IS not available,
MATERIALS ADDED TO FUEL
unleaded gasoline having a octane rating of 87 or
91 RON (Research Octane Number) may be used. Indiscriminate use of fuel system cleaning agents
In this case, the performance and fuel consumption should be avoided. Many of these materials
in-
WIII suffer a little degradatron.tended for gum and varnish removal may contain
highly active
solvents or similar ingredients that can
be harmful to gasket and diaphragm materials used
in fuel system component parts.
Gasolines containing alcohol
Some gasolrnes sold at service stations contain
alcohol, although they may not be SC identified. Use
of fuels containing alcohol is not recommended
unless the nature of the blend can be
determrned
as being satisfactory.
Gasohol
- A mixture of 10% ethanol (grain alcohol)
and 90% unleaded gasoline may be used
In your
car. If
driveability problems are experienced as a
result of using gasohol, it IS recommended that the
car be operated on gasoline. Methanol
- Do not use gasolines containing
methanol (wood alcohol). Use of this type of
alcohol can result in vehicle performance deteriora-
tion and damage critical parts in the fuel system
components. Fuel system damage and performance
problems, resulting from the use of gasolines
containing methanol, may not be covered by the
new car warranty.
Gasolines containing MTBE (Methyl Tertiary Butyl
Ether)
Unleaded gasolrne containrng
15% or less MTBE
may be used in your car. (Fuel containing MTBE
over 15% vol. may cause reduced engine per-
formance and produce vapor lock or hard starting.) RECOMMENDED

SELECTION OF LUBRICANTS
ENGINE OIL
Engine oil should be used which conform to the requirements
of the API classification “For Service SG” or “For Service
SGKD”, and have the proper SAE grade number for the
expected temperature range.
Caution
Nondetergent or straight mineral oil must never be used.
Energy Conserving Oil
In order to improve fuel economy and conserve energy new,
lower friction engine oils have been developed. These oils are readily available and can be identified by such labels as “Energy
Conserving”, “Energy Saving”,
“Improved Fuel Economy”,
etc.

Oil Identification Symbol
A standard
.symbol appears on the top of oil containers and has
three district areas for identifying various aspects of the oil.
The top
polqion will indicate the quality of the oil. The center
portion will show the SAE viscosity grade, such as SAE lOW-30.
“Energy Conserving” shown in the lower portion,
indicates that the oil has fuel-saving capabilities.

Example:
The safe operating temperature is - 15°C (5°F) when the measured specific gravity is 1.058 at the Coolant
temperature of 20°C (68°F).
Cautions
1. If the concentration of the coolant is below 30%, the anti-corrosion property will be adversely
affected. In addition, if the concentration is above 60%, both the anti-freeze and engine cooling
properties will decrease, affecting the engine adversely. For these reas\
ons, be sure to maintain the
concentration level within the specified range.
2. Do not use a mixture of different brands of anti-freeze.

SERVICE ADJUSTMENT PROCEDU$$o
ENGINE OIL CHECK
(1) Check to ensure that the engine oil level is within the level
range indicated on the oil dip stick.
(2) Check to ensure that the oil is not noticeably dirty or mixed
with coolant or gasoline, and that it has the proper
viscosity. IASH
ACIJUSTERS CHECKMllFEAGa
NOTE
Soon after the engine is started or while it is running,
abnormal noise (clattering) which may be attributed to the
adjuster sounds but does not stop. In this case, check the
following.
(1) Check the engine oil, and refill or replace oil if necessary.
NOTE
0If the oil amount is small, air will be sucked from the oil
strainer and mixed in the oil passage.
0If the oil amount is excessive, the oil will be stirred by
the crank and mixed with a large amount of air.
0Air and oil can not be separated easily in the deterio- rated oil, and the amount of air mixed in the oil
increases.
If such mixed-in air enters the high pressure chamber in
the lash adjuster, the air in the high-pressure chamber will be compressed while the valve is opened, the lash adjuster
will be excessively compressed and abnormal noise will be produced when the valve is closed.
This is the same phenomenon which occurs when the
valve clearance is improperly adjusted to be excessively
large.
However, it will return to be normal if the air entrapped in
the adjuster is released in this case.
(2) Start the engine, and slowly race* it several times (10 times or less).
If the
ablnormal noise is eliminated by racing the engine, it
means that the air is released from the high-pressure
chamber of the lash adjuster and the function of the lash
adjuster is returned to normal.
l
Graclually increase the engine speed from the idle
speed to 3,000 rpm (for 30 seconds), and then
gradually slow down the engine to the idling speed (for
30 seconds).
NOTE 0
If the vehicle is parked on a slope for a long time, the
oil will be sometimes reduced in the lash adjuster, and
air will enter the high-pressure chamber when the
engine is started. 0
After the vehicle is parked for a long time, the oil will go
out of the oil passage. Since it takes a little time to
supply oil to the lash adjuster, air sometimes enters the
high-pressure chamber.

(3) If any abnormal noise IS not eliminated by racing, check the
lash adjuster.
@ Stop the engine.
@ Set the engine so that cylinder No. 1 is positioned at
the top dead centre of the compression.
@ Press the rocker arm at the area indicated by the+ arrow mark to check whether the rocker arm is lowered
or not.
@ Slowly turn the crankshaft 360 degrees clockwise.
@ In the same procedure as Step 0, check the rocker
arm at the area indicated by the
0 arrow mark.
@ If the rocker arm lowers easily when the part directly
above the rocker arm lash adjuster is pressed, the lash
adjuster is defective and must be replaced. When re-
placing the lash adjuster, bleed the air from all adjus-
ters and then assemble them. Then inspect with proce-
dures
@ to 0, and confirm that there are no abnormal-
ities
NOTE
lThe lash adjuster can be accurately checked for de-
fects with the leak down test.
l Refer to the engine service manual for the leak down test and lash adjuster air bleeding procedure.
If the rocker arm is extremely hard when pressed
down, the lash adjuster is normal, so look for a different
cause of abnormal sound.
COMPRESSION PRESSURE CHECK
MllFFAL
(1) Before inspection, verify that the engine oil, starter motor and battery are normal. Then, perform the following.
l Engine coolant temperature:
80- 95°C
(176- 203°F)
l Lights, electric cooling fan and accessories: OFF
l Transaxle:
P range
0 Steering wheel: Neutral position
(2) Disconnect the spark plug cable.
(3) Remove all the spark plugs
(4) Disconnect the connector of the distributor.
NOTE
This will prevent the engine control module from controll- ing the ignition and fuel injection.
