routme

mamtenance

gUide

was

designed

to

help

the

home

mechanic

maintain

his

her

vehicle

with

Increased

performance

economy

safety

reliability

and

vehicle

life In

mind

Included

IS

a

maintenance

schedule

pro

cedures

grouped

according

to

time

mileage

Intervals

and

step

by

step

Instructions

which

deal

specifically

with

each

Item

on

the

schedule

The

procedures

range

from

visual

checks

and

adjustments

to

Item

re

placements

The

term

tune

up

IS

loosely

used to

descrrbe

a

serres

of

procedures

that

are

actually

part

of

the

routine

maintenance

schedule

ServIcing

your

vehicle

uSing

the

time

mileage

Intervals

and

the

accompany

Ing

Instructions

will

give

you

a

planned

pro

gram

of

maintenance

Keep

In

mind

that

It

IS

a

comprehensive

plan

and

maintaining

on

ly

a

few

Items

at

the

speCified

Intervals

will

not

produce

the

same

results

The

maintenance

procedures

are

arranged

In

the

order

that

they

should

be

done

and

are

grouped

to

make

the

entire

Job

as

easy

as

possible

Deciding

where

to

start

or

plug

Into

the

routine

maintenance

schedule

depends

on

several

factors

If

you

have

a

vehicle

whose

warranty

has

recently

expired

and

If

It

has

been

maintained

according

to

the

warranty

standards

you

may

want

to

begin

routine

maintenance

as

It

cOincides

with

the

next

mileage

or

calendar

Interval

If

you

have

owned

the

vehicle

for

some

time

but

have

never

performed

any

maintenance

on

It

then

you

may

want

to

start

at

the

next

In

terval

and

Include

some

additional

pro

cedures

to

ensure

that

nothing

Important

IS

overlooked

If

you

have

Just purchased

a

used

vehicle

and

have

no

knowledge

of

ItS

care

or

maintenance

record

you

may

want

to

combine

all

the

checks

Into

one

large

service

Initially

and

then

settle

Into

the

prescnbed

maintenance

schedule

The

first

step

In

thiS

or

any

maintenance

plan

IS

to

prepare

yourself

before

the

actual

work

begins

Read

through

the

approprrate

procedures

for

all

work

that

IS

to

be

per

formed

before

begin

Gather

If

It

appears

that

you

could

have

a

problem

a

particular

Job

t

heSitate

to

seek

Its

simply

the

result

of

approach

to

the

problem

Always

work

by

a

process

of

elimination

starting

With

solution

and

working

through

to

the

most

complex

and

never

overlook

the
