OWNER'S

SERVICE

POLICY

WHAT

IT

MEANS

With

your

Dodge

truck, you should

receive

an

Owner's

Service

Policy

and

also

an

Owner's

Identification

Card.

These should

be

properly

filled

in

by

your

dealer.

Read

the

Owner's

Service Policy

carefully

and

be

sure you

understand

your

obligations

and

privileges.

You

will

notice

two

coupons

attached

to

the

Owner's

Service

Policy. These coupons

entitle

you

to

have

your

truck

inspected,

by

the

Dodge

dealer

from

whom

it

was

purchased,

at

the intervals

shown on the coupons. There

will

be

no

charge

for

these inspections,

other

than

for

oil

and

lubricants used.

As

you

will

see

by

reading

the coupons, these

are

very

thorough

inspections

designed

to

assure you

that

your

truck

will

be

in satis-

factory

condition

during

the

life

of

the Service Policy.

We

suggest

that

you

continue

afterward

to

return the truck

to

your

Dodge

dealer

for

periodic

inspections

and

maintenance service.

OPERATING

THE

TRUCK

Into

your

new

Dodge

truck has

been

built

every

feature

known

to

modern

autolT)Otive

engineering

that

makes

for

greater

driving

ease,

control

and

safety.

Your truck is

thoroughly

responsive.

Anyone

who

can

drive

at

all

will

find

this truck

exceptionally

easy

to

handle.

But

with

the volume

of

traffic

on the

road

today,

and

with

this volume

steadily

increasing,

it

becomes

more

and

more

important

that

one

be

not

merely

an

adequate

driver,

but

an

expert

driver.

Careful

attention

to

the suggestions in this

manual

will

mean

that

you

and

your

truck

will

get

the

best

results

under

any

given

set

of

driving

conditions.

There's

more

to

being

an

expert

driver

than

proper

manipulation

of

the

truck.

One

most

important

sign

of

the

expert

is

the

care

he

gives

his truck. The

expert

driver's

truck

is

kept

in

condition

by

experts.

That

is

why

we

keep

urging

that

you

take

your

truck

to

your

authorized

Dodge

dealer

whenever

attention

is

required.

STARTING

THE

ENGINE

Hold

the clutch

pedal

down

while

starting

the

engine.

This prevents

any

danger

of

the

vehicle

starting

before

you're

ready,

in the

event

that

the

transmission

had

been

accidentally

left

in

gear.

When

you

hold

down

the clutch

pedal,

the

starter

does

not

have

the

burden

of

turning

the

gears

in the transmission as

well

as

cranking

the

engine.

Turning the

ignition

switch

key

to

the

right

connects

the

ignition.

If

the

engine

is

cold

the

choke

control

button

should

be

pulled

out.

The

starter

pedal

should then

be

pushed

down

with

the

foot

to

the

limit

of

its

travel.

As soon as

the

engine

starts

to

run

under

its

own

power,

the

starter

pedal

should

be

released.

In

cold

weather

it

is

advisable,

after

the

engine

is

running

properly,

to

engage

the clutch slowly,

so

that

the

engine

will

not

be

stalled

by

the thick

oil

in

the trans-

mission. The choke

button

should

be

pushed in

immediately

to

its

best

running

position

and

all

the

way

in as soon as

the

engine

is

warm

enough

to

permit

it.

Remember,

if

your

engine

has

been

cold,

it's

always

best

to

let

it

idle

a

few

minutes

before

starting

off,

and

then

drive

slowly

awhile

to

let

it

warm

up

thoroughly.

This

is

important

to

insure

proper

circulation

of

oil

to

all

parts,

and

that

can't

be

done

before

your

engine

attains

its

proper

operating

temperature.

If

the

engine

does

not

start

readily

when

hot, the

throttle

control

button

should

be

pulled

all

the

way

out

and

the choke pushed

all

the

way

in.

This

will

allow

any

unvaporized

fuel which

may

have

accumulated

in the

manifold

or

cylinders

to

be

quickly

cleared

away.

The

throttle

control

button should

be

pushed

at

least

most

of

the

way

in as soon as the

engine

starts.

THE

RECOMMENDED WAY

TO

SHIFT

GEARS

Under

nearly

all

conditions

your

truck should

be

started

in

low

gear.

But

very

shortly

you

can shift

to

second, unless

starting

on a

grade.

It

is

usually

best

to

shift into

high

gear

at

about

20

to

25

miles

per

hour.

When

rapidly

shifting

gears

it

is

advisable

to

double

clutch. That

is,

when

shifting

to a higher

gear,

release

the clutch

and

shift

to

neutral,

engage

the clutch

so

that

its

speed

will

be

reduced

with

reduced

engine

speed.

Then release the clutch

again

and

shift into

the

higher

gear.

When

shifting

to

a

lower

gear,

release

the clutch

and

shift

to

neutral,

engage

the clutch

and

speed

the engine

up

to

the

speed

it

will

have

to

run in the

lower

gear.

Then release the clutch

and

quickly

shift

to

the

lower

gear.

With

a

little

practice,

double

clutching can

be

done

fast

and

e-

asily

and

the

advantages

will

be

readily

recognized.

HANDLING

high

gear

when

climbing a long

or

steep

hill. Your

truck

needs its

gears,

and

you

should use the

gears

for

the

purpose

for

which

they

were

intended.

Even

if a steep

hill

can

be

climbed

in high,

it

is

usually

better

to

shift

to a lower

gear

while

the vehicle still has

good

momentum,

thereby

saving

time as

well

as strain on

the

engine

and

minimizing the inconvenience

of

stalling.

Before

starting

down a steep

or

long

grade,

it

is

advisable

to

shift

to

the same

gear

you

would

use

if

driving

up

the

hill.

Shift

to

the

lower

gear

and

engage

the clutch

at

once

to

hold

the

vehicle

speed

down.

Do

not

allow

the

vehicle

to

gain

speed

after

shifting

to a lower

gear

and

then

engage

the

clutch, as

such

an

operation

is

almost

sure

to

cause

damage

to

the

drive

line

of

the

vehicle.

If

the truck

is

equipped

with

a

governor,

it

cannot

be

driven

faster

than the

speed

for

which the gover;nor

is

set

when

on

level

roads

or

when

going

up

any

grade.

When

going

down

hill,

do

not

under

any

circumstances

allow

the

truck

to

exceed

the

governed

speed

of

the

engine.

Faster speeds

will

"rev

up"

the

engine

beyond

the

requirements

for

which

it

was

designed

and

built,

and

is

almost

sure

to

cause

damage.

Use the

brakes

intermittently

to

hold

the

speed

of

the truck

within

limits.

FACTS

ABOUT ECONOMY

Real

economy

has

been

engineered

and

built

into

your

Dodge

truck. Economy,

however,

varies

with

different

operating

and

load

conditions which

cannot

be

controlled

by

the truck

manufacturer,

but

can

be

controlled

by

the

driver.

Overload

and

high

speeds

are

the

greatest

enemies

of

economy.

Either

of

these conditions increase

operating

and

maintenance

costs

to

the

point

where

they

become

expensive

rather

than

eCQ-

GROSS

WEIGHT = WEIGHT

OF

TRUCK + PAYLOAD

nomical. Your truck should not

be

loaded

above

the recommended

gross

laden

rating.

The gross

laden

rating

means the combined

weight

of

the

complete

truck

and

the

load

it

carries. To determine

the gross

laden

weight

of

your

truck,

weigh

the truck just as

it

oper-

ates when

fully

loaded.

Unnecessary

high

vehicle

and

engine

speeds should

be

avoided.

More

power

is

required

to

propel

a vehicle a

given

distance

at

50

miles

per

hour

than

would

be

required

to

propel

the vehicle the

same distance

at

30

miles

per

hour.

Therefore

fuel

and

oil

con-

sumption

is

increased

by

high

speeds.

Sudden

starts

and

stops reduce

fuel

economy

and

increase main-

tenance costs.

Tires should

be

inAated

to

the recommended pressure

and

wheel

alignment

maintained.

Under-inAated

tires

or

misaligned

wheels

wdste

fuel

because

they

increase

rolling

friction, which means

that

more

power,

hence

more

fuel,

is

required

to

move the truck.

A"owing

the

engine

to

idle

while

the

truck

is

standing

for

any

length

of

time

will

cut

down

fuel

economy

and

increase

operat-

ing

costs.

Engine

operating

temperature

is

an

important

factor

in engine

economy. Engine

operating

temperatures

that

are

above

normal

will

increase.

engine

oil

temperatures

and

reduce

oil

economy.

When

the engine

is

continuously

operated

below

normal

operating

temperatures

the

fuel

mixture

is

not

completely

burned

in the com-

bustion chambers. Some unburned

fuel

passes the pistons

and

dilutes the engine

oil.

Also, condensation

and

sludge

may

form

in

the crankcase. Dilution, condensation

or

sludge

deteriorate

oil

and

promote

rapid

wear

of

the engine

parts

which the

oil

is

expected

to

protect.

Your

Dodge

truck

engine

is

equipped

with

advanced

and

out-

standing

features which,

under

normal

operating

conditions,

will

automatically

maintain

the

proper

engine

operating

temperature

and

ventilate

the crankcase.

If

your

engine

is

operated

under

unusual conditions

and

normal

engine

temperatures

are

not

main-

tained,

suffer

and

it

is

suggested

that

you

see

your

Dodge

dealer

for

his recommendations.

Brake

adjustments should

be

checked, and the

engine

tuned,

periodically.

Maintenance

and

lubrication

as

specified

in this

manual

will

insure engine

efficiency

and

help

materially

to

reduce

power

loss,

thereby

improving

economy.

GENERAL

CARE

OF

YOUR

TRUCK

We

hope

that

you

are

very

proud

of

this truck,

and

if you

are,

of

course you

will

want

to

keep

it

always

as

clean,

neat

and

trim-

looking

as

it

can

possibly be.

This

is

not

hard

to do.

WASHING AND POLISHING

The finish on your truck should

be

washed

often enough

to

keep

it

free

from dust

and

road

scum.

This

should

be

done

by

using either

cold

or

warm

water

and a sponge

followed:with a

damp

chamois.

A mild

soap

may

be

used occasionally if

desired,

with a thorough

rinsing

afterwards.

Your truck should

always

be

washed

in a shaded

place,

as

washing

it

in

strong sunlight

may

result

in

water

spotting

and

staining which

are

difficult

to

remove.

It

is

particularly

important

during

the

winter months

to

make

sure

that

anti-freeze

preparations

do

not

get

on the

finish. It

is

common

practice

in

most communities to use chemicals, particularly calcium

(i1

C

LEAliE

It

CLEANING

THE

CAB

10

chloride, on the

streets

to melt snow

and

ice.

The

use

of

such chemi-

cals results

in

a slush

whi~h,

if

it contacts the

finish

on your truck,

will

be

harmful unless it

is

washed

off

as

soon

as

possible.

If

the paint

surface

is

not

kept

clean,

the action

of

the elements

and

accumulation

of

dirt,

road

scum, corrosive salts, etc.,

will

even-

tually

cause

ddmage

to the

finish

and

also

present a very

unattrac-

tive

appearance.

The more

frequent

washings

will

eliminate the

necessity

of

using polish.

If,

after

extended

neglect, strong sunlight

and

the elements

have

caused the finish to dull, MOPAR Liquid

Automobile Polish

can

be

used

to

restore

the luster

of

the

finish.

Paste

wax

and

abrasive

cleaners

are

not recommended.

CLEANING

GLASS

In

cleaning windows, windshield

and

other

glass equipment, use

MOPAR Glass

Cleaner

or

wash with

water

and

wipe

dry

with a

linen cloth

or

chamois. A cloth slightly

dampened

with house-

hold

ammonia will remove the thin scum difficult to remove with

water

alone.

CLEANING

THE

RUNNING

GEAR

Cleaning the

under

side

of

the truck

and

the inside

of

the wheels

can

best

be

done

with a small, powerful stream

of

water

from a

hose.

This

stream

dislodges mud

and

dirt that

may

have

accumu-

lated.

Occasionally, the use

of

a stiff brush

may

be

necessary.

REMOVING

TAR

OR

ROAD

OIL

Tar

or

road

oil

can

be

removed from the

cab

and

body

without

injury to the finish

by

using

one

of

the

standard

brands

of

tar

remover.

If

the

tar

has

hardened

into lumps, soften it first

by

using

lard,

butter

or

kerosene,

after

which

treat

the finish with MOPAR

Liquid Automobile Polish.

CLEANING CHROME TRIMMING

Clean

the grille

and

other

chromium-plated

parts

with MOPAR Chro-

mium

Polish.

It

removes rust

where

the plating has

been

scratched

or

rubbed

off

and

covers the

spot

to

prevent

more rust forming.

LUBRICATION

LUBRICATION

The

present

day

commercial

vehicles

perform

an

entirely

different

type

of

service

from

that

of

a short

time

past.

Higher

speeds

are

developed

and

longer

distances

are

traveled

in

shorter

time.

This

type

of

performance

demands

very

exacting

lubrication

. The

necessary

mechanical changes

have

brought

about

the

necessity

for a variety

of

lubricants

to

take

care

of

the

lubrication

require-

ments

adequately.

Proper

lubrication

is

of

vital

importance

to

you in the economical

operation

of

your

truck. We

urge

you

to

read

carefully

+he

follow-

ing

paragraphs

concerning this subject

and

study

the

lubrication

charts on

pages

17

to

22,

inclusive, so

you

will

know just

what

the

lubrication

requirements

are

for

your

truck.

ENGINE

OIL

RECOMMENDA

nONS

The

engine

oil

recommendations

given

in the

lubrication

chart,

page

17,

are

based

upon

the

principle

that

the

lower

viscosity oils

circulate

more

rapi

dly

and

lubricate

parts

with

closer

clearances

more

readily

than

the

heavier

oils. Their

complete

satisfaction,

how-

ever,

depends

upon

the

use

of

only

well

refined

or

high

quality

product,s. Purchases should

be

made,

therefore, only

from

reputable

manufacturers

or

dealers

.

For sub-normal

winter

conditions such as

temperatures

below

-10

°

F.,

the

No.1 0-W should

be

diluted

with

about

10%

colorless

12

reflned kerosene, which should

be

thoroughly mixed with the oil

before

being

added

to the engine.

If

this

is

not convenient, consult

your

dealer

or

any

reputable

oil

company

who sh.ould

have

spe-

cially

prepared

oils for these conditions.

FIRST

1,000

MILES

During the first

1,000

miles, it

is

recommended

that

you use the

engine

oil

(No.

lOW)

which

is

in

the oil

pan

when the truck

is

deliv-

ered.

If

necessary

to

add

oil during the first

1,000

miles, No.

10-

W

should

be

used

regardless

of

the

season

of

the

year

or

climatic

conditions.

AFTER

1,000

MILES

When

your

speedometer

registers

1,000

miles, the oil

pan

should

be

drained

and

refilled with the

proper

viscosity oil according to

the

anticipated

atmospheric

temperature.

See

lubrication chart,

page

17, for

engine

oil

recommendations

and

frequency

of

oil

changes.

The

oil

pan

should

be

drained

while the

engine

is

at

normal

operating

temperature

. Oil

will

drain

more completely when hot,

and

will,

therefore,

carry

more

of

the foreign

matter

with

it.

ABNORMAL CONDITIONS

WINTER

DRIVING-If

the truck

is

driven

for

short distances

of

only

a

few

miles

at a time

and

at

low

speeds,

or

is

engaged

in

frequent

stops

or

door-to-door

delivery

type

of

service, moisture

wi"

con-

dense in the

oil

pan

and

form a sludge,

which

may

freeze

and

clog

the

oil

inlet

screen.

Under

conditions

of

this kind the

engine

does

not

become

sufficiently

warm

to

expel

the

condensation

through

the

crankcase

ventilating

system

and

the

engine

oil

should

be

changed

approximately

every

500

miles-under

extreme

conditions more

often

may

be

necessary

.

This

sludging

condition

can

be

corrected

to a large

degree

by

the use

of

various

equipment,

which tends

to

increase the

engine

temperature

rapidly,

such

as

1800 thermostats,

winterfronts,

etc.

Note:

When

using 1

800 thermostats

it

is

necessary

to

use a

per-

manent

type

of

anti-freeze

to

prevent

boiling

away.

As

an

alternative

to

this

frequent

change

period

or

use

of

special

equipment,

an

occasional

drive

of

30

miles

or

more

at

higher

speeds

will

do

much

toward

expelling

the

condensation

through

the

crankcase

ventilating

system.

If

these

longer

drives

are

made

fre-

quently,

the

change

period

may

be

extended

to

the

normally

rec-

ommended

winter

change

.

DUSTY

CONDITIONS-Driving

over

dusty

roads

or

through

dust

storms introduces

abrasive

material

into

the engine.

If

the

air

clean-

ers

are

kept

in

good

condition,

they

will

decrease

the

amount

of

dust

entering

the

crank

chamber.

However,

if

the

engine

oil

becomes

contaminated

with

dust

or

dirt

the

oil

pan

should

be

promptly

drained,

flushed

out

and

refl"ed

with

new

oil

of

the

prope.r

grade

to

prevent

harmful

engine

wear.

The

frequency

of

draining· depends

upon

the

severity

of

the dust conditions,

therefore,

no

definite

drain-

ing

periods

can

be

recommended.

CHECKING OIL

LEVEL

Each time you stop

for

fuel

the oil

level

should

be

checked.

The oil

level

indicator

is

marked

at "FULL" and

"ADD

OIL."

The "

FULL

"

mark

shows the

proper

level

of

oil

after

the engine has

been

stand-

ing

for a few

hours. As soon as the

engine

has

started

running, the

level

wi"

drop

somewhat,

due

to

the

fI"ing

of

oil

passages

and

the

filter.

14

ADD OIL MARK

CHECKING

THE

OIL

LEVEL

A

quart

of

oil

should

be

added

when

the level

is

at

or

just

above

the

"ADD

OIL"

mark

on the oil

level

indicator.

The

level

should

never

be

allowed

to

drop

below

the

"ADD

OIL"

mark.

OIL

FILTER

The function

of

the

oil

filter

on the

engine

is

to

remove

dirt

and

for-

eign

material

from

the oil in

order

to

assist in

keeping

the oil clean.

This

is

a continuous process,

and

the

filter

element

will

continue

to

trap

dirt

until

it

becomes

clogged

. Due

to

the

manner

of

connecting

the

oil

filter

to

the

oiling

system,

clogging

of

the

filter

will

not

stop

the

circulation

of

oil

to

the

bearings.

However,

when

the oil

filter

is

clogged

it

ceases

to

filter

the

oil.

It

is

advisable,

therefore,

to

install a

new

oil

filter

or

filter

element,

depending

on

the

type

of

filter

used,

every

10,000

miles.

In

dusty

areas

it

may

be

advisable

to

examine

the

oil

and

service the

filter

more

frequently,

or

at

any

time when the

oil

appears

to

be

excessively

dirty.

AIR

CLEANER

Road

dust

and

other

abrasives

are

filtered

out

of

the

air

entering

your

engine

through

the

carburetor,

by

means

of

an

air

cleaner. The

cleoning

and

servicing

of

the

air

cleaner

is

covered

on the

lubrica-

tion chart,

page

17.

If

properly

and

periodically

serviced, the

parts

of

the

engine

subjected

to

wear

are

protected

from the

abrasive

action

of

dust

and

dirt.

The result

is

much

longer

engine

life

and

economy

and

efficiency

is

maintained

for

thousands

of

extra

miles. The

air

cleaner

should

be

serviced

at

regular

intervals,

even

daily

may

be

necessary

under

extreme

conditions in dusty

territory.

CRANKCASE

VENTILATION

In

the

operation

of

an

automobile

engine,

the engine oil

is

sub-

jected to dilution

and

contamination

by

water,

fuel, acid

and

other

foreign elements which

reduce

the lubricating quality

of

the

oil.

In

your

Dodge

engine, a

special

ventilating system.

expels

a

large

amount

of

these

undesirable

elements,

but

enough remain

to

make

it

advisable

to

drain

the crankcase

at

the

intervals recommended

in

this manual.
Accumulations

of

non-lubricating elements

in

the engine oil

have

a

damaging

effect on highly finished

metal

surfaces.

Water

has

no

lubricating value,

and

is

likely to

freeze.

Fuel thins the oil, thus

reducing its value

as

a lubricant. Acid

attacks

m~tal

surfaces, caus-

ing excessive

wear.

Air

for

ventilating the crank

chamber

enters

the oil filler

pipe.

This

air

is

filtered

by

passing through the

air

cleaner

in

the filler

pipe

cap.

Therefore,

in

order

for the

crankcase

ventilation system

to function efficiently

and

expel

as

much

of

these

undesirable

ele-

ments

as

possible, the oil filler

pipe

air

cleaner

should

be

serviced

as

recommended

in

the lubrication chart,

page

18.
