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

ExampleThe 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).
Cautions1. 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 reasons, be sure to maintain theconcentration level within the specified range.
2. Do not use a mixture of different brands of anti-freeze.

Any replacement oil filter should be installed in accordancewith the oil filter manufacturer’s installation instructions.
(1) Remove the engine oil filler cap.
(2) Remove the engine oil drain plug, and drain out the
engine oil.
(3) Remove the engine oil filter by using the oil filter
wrench.(4) Clean the oil filter mounting surface of the oil filter
bracket.(5) Coat engine oil to the O-ring of new oil filter.
(6) Turn the oil filter by hand to install to the block.
NOTEThe oil filter tightening torque is

necessary.9. MANUAL TRANSAXLE (Inspect oil level)
NOOSBCEbInspect each component for evidence of leakage, and
check the oil level by remaining the filler plug. If the oil is
contaminated, it is necessary to replace it with new oil.
1. With the vehicle parked at a level place, remove the
filler plug and check to be sure that the oil level is up tothe lower edge of the filler plug hole.
2. Check to be sure that the transmission oil is not
noticeably dirty, and that it has a suitable viscosity.

Symptom
NOTE
1 Probable cause1 Remedy
In addition to a malfunction of the differential carrier components, abnormal noise can also be caused by the universal
joint of the propeller shaft, the axle shafts, the wheel bearings, etc. Before disassembling any parts, take all
possibilities into consideration and confirm the source of the noise.

Noise from the engine, muffler vibration, transaxle, propeller shaft, wheel bearings, tires, body, etc., is easily mistaken
as being caused by malfunctions in the differential carrier components. Be extremely careful and attentive whenperforming the driving test, etc.
Test methods to confirm the source of the abnormal noise include:coasting acceleration, constant speed driving,
raising the rear wheels on a jack, etc. Use the method most appropriate to the circumstances.

BRAKES - Service Adiustment Procedures5-45I
\\14A0416
2314A04.54
BLEEDINGN65FYAN
When the master cylinder is empty of brake fluid, bleed air
from the master cylinder by proceeding with procedures (1)
thru (6). (Because this master cylinder is not equipped with a
check valve.)
When brake fluid remains in the master cylinder, proceed with
step (6).
(1) -Disconnect the brake tube from the master cylinder.
(2) Two persons should conduct the air bleeding, one person
slowly depressing the brake pedal and holding the pedal
depressed.(3) In this condition, the other person should use a finger to
close the outlet part of the master cylinder, and then the
first person should release the brake pedal.
(4) Steps (2) and (3) should be repeated three or four times,
and then the master cylinder should be filled with brake
fluid to the specified level.
NOTE
The air is completely bled from the master cylinder by steps
(1) to (4).
(5) Connect the brake tube to the master cylinder.
(6) Start the engine; then, in the sequence shown in the
illustration, bleed the air from each wheel cylinder.
Specified brake fluid: MOPAR Brake Fluid/
Conforming to DOT3
Caution
1.Use the specified brake fluid. Avoid using a mixture
of the specified brake fluid and other fluid.2. If brake fluid is exposed to the air, it will absorb
moisture; as water is absorbed from the atmos-phere, the boiling point of the brake fluid will
decrease and the braking performance will be
seriously impaired. For this reason, use a hermeti-
cally sealed 1 lit.
(1.06 qt.) or 0.5 lit. (0.52 qt.) brake
fluid container.3. Firmly close the cap of the brake fluid container
after use.
4. For vehicles with the anti-lock braking system, besure to install a filter to the master cylinder
reservoir tank when supplying brake fluid.
ORDINARY AIR-BLEEDING PROCEDURES(1) Depress the brake pedal several times until resistance is
felt; then, with the pedal depressed, loosen the bleeder
screw
l/3 to l/2 turn and then tighten it before the fluid
pressure is all gone.
(2) Release the brake pedal. Repeat this procedure until there
are no more air bubbles in the brake fluid.
