Engine Oil

For
maximum
engine
protection under all driving conditions encountered during the recommended

oil
change intervals, it is necessary to use only

"MS"
certified
sequence-tested
oils. The term
"MS"
must appear on the oil container singly or

in
conjunction with other designations. "MS" des­
ignated oils are heavy-duty detergent oils that are
formulated to withstand all service conditions in
modern powerplants. Engine oils designated only
as
"ML"
and/or
"MM"
are not recommended and should not be used except in an emergency when

"MS"
oil is not available. Certified
sequence-tested

engine
oils are described on their containers by

such
phrases as:
meets,
exceeds,
excels, or has
proven superior in the
test
requirements,
test
sequences, MS Service
tests,
standards, and service

requirements,
of automotive manufacturers, auto­
makers,
or car manufacturers for MS service or
Service
MS.
It
may be necessary to change
engine
oil more
frequently than normally recommended, depending upon the type and quality of oil used, the severity
of operation conditions, if the
engine
is used for
short
periods in cold weather, or if the
engine
is allowed to idle for excessive periods.

Always
drain
the crankcase while the
engine
is hot since
dirt
and contaminants are then more
likely
to be held in suspension and therefore
will

drain
out more completely.
Drain
the crankcase as follows:

a.
Position the
drain
receptacle under the
drain

plug.

b.
Remove the
drain
plug using the correct size

wrench.
Be careful of hot oil.
c.
Carefully
clean the
drain
plug. Inspect and

replace
the gasket, if deteriorated.
d.
When the oil has drained, replace and tighten
the crankcase
drain
plug. 12

solvent.
Wrap
the polyurethane element in a clean

dry
cloth and
squeeze
to remove all possible sol­
vent. Do not wring the element or it may
become
torn.
After cleaning, oil the polyurethane element

liberally
with
engine
oil
(SAE
10W30) and
squeeze

to evenly distribute the oil through the element and to remove
excess
oil. The element should be damp

with
oil, not dripping.
Install
the polyurethane element on the paper element, taking care to have
edges
of the polyurethane element over the plastic end plates of the paper element.

Replace
the complete air cleaner element assembly every
24,000
miles
[38.400
km.]. Replace more
frequently if there is any apparent damage or evidence of plugging.

The
crankcase ventilation filter should be replaced, not cleaned, every
6,000
miles
[9.600
km.]. The
filter
is located inside the air cleaner housing.

Steering
Gear

Check
that the steering gear lubricant is at the
level of the fill-hole. If not, add lubricant to the
level of the fill-hole with the lubricant recom­ mended in the
Lubrication
Specifications. If abnor­

mally
low, check the steering gear for possibility
of leaks.

B-28.
Cooling System
Check
the coolant level in the
radiator.
It should be

half
an inch below the neck. If not,
fill
the radiator
to
half
inch below the neck with the proper coolant.

Refer
to Section G.

If
the level of the coolant is abnormally low, check
the radiator,
hoses
and water pump for possible
leaks.
If a leak is suspected, refer to Section G.

For

General

All
transfer cases and transmissions should be

serviced
separately even though drilled passages
are
provided for oil circulation
between
some
trans­
mission and the transfer case housings. Procedure

from
the appropriate Par. below should be fol­ lowed to check the lubricant level of the various

types
of transfer cases and transmissions.
If
the transfer case or transmission fluid levels
are
found to be abnormally low, check both units
for any possible leaks.

B-32.
Transfer
Case
:

The
transfer case fill-hole is located on the right side of the transfer case housing. To check the
lubricant
level, remove the
fill
plug.
Lubricant

should be level with this fill-hole. If not, bring up to level by adding make-up lubricant as specified

in
the
Lubrication
Specifications.

B-33.
Transmission

The
transmission fill-hole is located on the right side of the transmission housing. To check the
lubricant
level, remove the
fill
plug.
Lubricant

should be level with this fill-hole. If not, bring
up to level by adding make-up
lubricant

Refer to Par. B-35 through B-37 as applicable.

B-35.
General

Transfer
case and transmission lubricants should
be changed at the same time.

B-36.
Transfer
Case

To
drain
the transfer case, first remove the transfer
case fill-hole plug and then the transfer case
drain-

hole
plug. Let all fluid
drain
from case.
Then
install
the transfer case drainhole plug, and
refill
the
transfer
case through the fill-hole using the correct

lubricant
as specified in the
Lubrication
Specifica­
tions.

At
30,000
mile
[48,000
km.] intervals lube the

transfer
case shift levers with
Lubriplate
No.
130AA.
Late
models have a lube fitting. To lube
older models, (without lube fitting) remove the

bottom
cover of the case, clean thoroughly and
pack
case
full
of lubricant.

B-37.
Transmission (3-Speed)

To
change the lubricant on all vehicles equipped

with
a three speed synchromesh transmission,
drain

the old fluid by first removing the fill-hole plug

and
then removing the drainhole plug. Since on

some
transmissions there are drilled passages be­ tween the transmission and transfer case that allow

oil
to circulate
between
the two units, the transfer
case should be drained before refilling the trans­

mission.

When
all the fluid is completely drained, replace
the drainhole plugs only. For the correct specifi­
cations and quantity, refer to the
Lubrication
Specifications. 15

HURRICANE
F4
ENGINE

The
Prestolite distributor on the F4
engine
is
mounted on the right
side
of the
engine
and is op­
erated by a coupling on the oil pump shaft, see Fig.
D-l,
which is driven by a spiral gear on the cam­
shaft. The spark advance is fully automatic, being controlled by built-in centrifugal
weights.
The Pres­

tolite
distributor on the V-6
engine
(Fig. H-8) is mounted at the
left
front of the
engine
on the tim­
ing chain cover. It is driven by a spiral gear on the
camshaft. The spark advance is fully automatic,
being controlled by built-in centrifugal
weights,
and by a vacuum advance system. While
some
parts of the distributor may be checked or replaced
with the unit mounted on the
engine,
it is
best
to periodically remove it for a thorough check. Infor­ mation covering the parts which can be serviced
without removal is
given
below.
The
Prestolite distributor installed on the V-6 en­

gine
is similar in construction to the distributor in­
stalled on the F4
engines
except
for the addition of

a
vacuum advance mechanism.
The
same checking procedures outlined in Par. C- 10a, are used for the Prestolite V-6 distributor with

exception
of specifications.
H-10. Distributor Cap

The
distributor cap should be inspected for cracks,
carbon runners and
evidence
of arcing. If any of

these
conditions
exists, the cap should be replaced.
Clean
any corroded high
tension
terminals.

H-11.
Rotor
Inspect the rotor for cracks or
evidence
of
excessive

burning at the end of the metal strip.
After a distributor rotor has had normal use the
end of the rotor will
become
burned. If burning is found on top of the rotor it indicates the rotor is
too short and
needs
replacing. Usually when this condition is found the distributor cap
segment
will 178

License Plate
Light

On
CJ-5A,

and current production vehicles
the license plate light is attached to the tailgate
and
is of the swing-type design to enable the
license plate to be visible when the tailgate is in
the down psoition. The bulb can be changed by
removing
the clear plastic lens. On early production
vehicles the license plate light is integral with the

tail
light assembly.

H-137.
Horn
The
horn is mounted under the hood on the
left

front
fender. The horn is sounded by pressing the
button located at the top center of the steering
wheel.

To
remove the horn wire, disconnect the wire at
the snap connection at the base of the steering
column.
Pull
off the rubber horn button cap and
the brass contact cap from the steering wheel nut.

This
will
expose
the contact tip of the horn wire.

Pull
the wire out of the steering column from the top. Refer to Fig. H-62.

Directional
Signals

The most frequent causes of

in
the directional signal system are
loose
connec­
tions and burned-out bulbs. A flashing rate

approximately
twice the normal rate usually in­
dicates a burned-out bulb in the
circuit.

When
trouble in the signal switch is suspected it
is advisable to make the following
test
to definitely
locate the trouble before
going
to the effort of

removing
the signal switch. If, for example, the
right

are
inoperative and switch failure is indicated, first put the control lever in neutral position.
Then

disconnect the wire to the right side
