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.

GENERAL -Maintenance Service
(1O)Star-t engine and allow to idle for at least two minutes.
Then, with parking brake on, move selector
fever
momentarily to each position, ending in “N” Neutral
position.
(11)Add sufficient ATF to bring fluid level to lower mark.
Recheck fluid level after transaxle is at normal Operating
temperature. Fluid level should be between upper and lower marks of
“HOT” range, Insert dipstick fully to prevent dirt from
entering transaxle.

COOLANT (Change)MOOSEEAC
Check the cooling system parts, such as radiator, heater,
and oil cooler hoses, thermostat and connections for
leakage and damage.
CHANGE COOLANT
1. Remove the radiator cap.
2. Loosen the drain plug to drain the coolant.
3. Drain the coolant from the reserve tank.
4. After draining the coolant, tighten the drain plug securely.
5.Supply the coolant into the radiator until it is filled up to
its filler neck.
6. Supply the coolant into the reserve tank.
7. After warming the engine until the thermostat opens, remove the radiator cap and check the coolant level.
8.Supply the coolant into the radiator until it is filled up to
its filler neck, and install the radiator cap securely.
9.Fill the reserve tank with coolant up to the “FULL” line.

Check for fluid contamination and wear. Replace complete
set of pads if defective.
Caution
The pads for the right and left wheels should be
reDlaced at the same time. Never “split” or intermix
brkke pad sets.
All four pads must be replace as a complete set.

WHEEL CYLINDERS (Inspect for wear and
leaks)MOOSBGB
1. Remove the brake drum and check the thickness of brake shoe lining for wear. Check the automatic brake
adjusting system by hand to see if it operates smoothly.
Also see if the gears are in proper mesh with each
other. To assure smooth functioning, apply a very thin
coat of multipurpose grease to the friction surface of
adjuster and link shaft.

OPERATION
l The heated oxygen sensor functions to detect
the concentration of oxygen in the exhaust gas;
it converts those data to voltage, and inputs the
resulting signals to the engine control module.
l If the air/fuel mixture ratio is richer than the
theoretical air/fuel mixture ratio (i.e., if the con-
centration of oxygen in the exhaust gas is
sparse), a voltage of approximately IV is output;
if the air/fuel mixture ratio in leaner than the
theoretical air/fuel mixture ratio (i.e., if the con-centration is dense), a voltage of approximately
ov is output.
TROUBLESHOOTING HINTS
HINT 1:
The exhaust gas purification performance will wor-
sen if there is a malfunction of the heated oxygen
sensor.
Hint 2:
If the heated oxygen sensor output voltage deviates
from the standard value even though the results of
the checking of the heated oxygen sensor are nor-
mal, the cause is probably a malfunction of a com-
ponent related to mixture control.
l The engine control module, based upon those
signals, regulates the amount of fuel injection so
that the air/fuel mixture ratio becomes the
theoretical air/fuel mixture ratio.
lBattery power supply is applied, by way of the
multiport fuel injection relay, to the oxygen sen-
sor heater. As a result, the sensor element is
heated by the heater, so that the heated oxygen
sensor shows excellent response even if the
temperature of the exhaust gas is low.
Examples:
(1) Malfunction of an injector.
(2) Air leakage into the intake manifold from a leak-
ing gasket.
(3) Malfunction of the volume air flow sensor, the intake air temperature sensor, the
barometric-
pressure sensor, or the engine coolant tempera-
ture sensor.
