KO998
If the level is below the bottom of the filler plug hole, you’ll need to add
some lubricant.
If the differential is at operating temperature (warm), add enough lubricant to
raise the level
to the bottom of the filler plug hole.
If the differential is cold, add enough lubricant to raise the level to 1/2 inch
(12 mm) below the filler plug hole.
What to Use:
Refer to the Maintenance Schedule to determine what kind of lubricant to
use. See “Recommended Fluids and Lubricants” in the Index.\
Engine Coolant
The following explains your cooling system and how to add coolant when it is
low.
If you have a problem with engine overheating, see “Engine
Overheating’’ in the Index.
The proper coolant
for your vehicle will:
Give freezing protection down to -20°F (-29°C) or -34°F (-37°C) for
Give boiling protection up to 258°F (125°C).
Canadian vehicles and vehicles with the cold climate option.
Protect against rust and corrosion.
Help keep
the proper engine temperature.
Let the warning lights and gages work as they should.

13. ENGINE ACCESSORY DRIVE BELT INSPECTION*-Inspect belt. Look
for cracks, fraying, wear, and proper tension. Adjust or replac\
e as needed.
14. TIRE AND WHEEL ROTATION AND INSPECTION -For proper wear and maximum tire life, rotate tires at the first
6,000 miles (10 000
kilometers) for Schedule I or 7,500 miles (12 500 kilometers) for
Schedule
II and then every 15,000 miles (25 000 kilometers) thereafter.
Follow the instructions and patterns shown in Section
6. Check tires for
uneven wear or damage.
If irregular or premature wear is apparent,
check wheel alignment. Also, check for damaged wheels. See “\
Tires” in
the Index for more information.
15. DRIVE AXLE SERVICE -Check rear/front axle fluid level and add \
as
needed. Check constant velocity joints and axle seals for leaki\
ng.
Locking differential -Drain fluid at first oil change and refill. Check
fluid level and add as needed at subsequent oil changes. In d\
usty areas
or trailer towing applications, drain fluid at every 15,000 miles
(24
135 kilometers) and refi1l.t
Standard differential -Check fluid level and add as needed at
every oil change. In dusty areas or trailer towing applications\
, drain
fluid every
15,000 miles (24 135 kilometers) and refil1.t
More frequent lubrication may be required for off-road use.
16. BRAKE SYSTEM INSPECTION -When the engine oil is changed,
inspect the lines and hoses for proper hookup, binding, leaks, \
cracks,
chafing, etc. Check the parking brake adjustment, and the fluid\
level in
the master cylinder. A low fluid level can indicate worn disc \
brake pads
which may need to be serviced.t
When the wheels are removed for rotation, inspect disc brake p\
ads for
wear and rotors for surface condition. Also inspect drum brake \
linings for
wear and cracks. Inspect other brake parts, including drums, wh\
eel cylinders, parking brake, etc., at the same time.
Inspect brakes more often if driving habits or conditions resul\
t
in
frequent braking.
tA fluid
loss in these systems may indicate a problem. Have them inspected
and repaired at once.
