ADVICE
FORTHE
BEGINNER
The
tips
in
the
paragraphs
that
follow
are
general
advice
to
help
any
do-it-yourself
BMW
owner
perform
repairs
and
main-
tenance
tasks
more
easily
and
more
professionally
.
Planning
Ahead
Cleanliness
Keeping
things
organized,
neat,
and
clean
is
essential
to
do-
ing
a
good
job
.
When
working
under
the
hood,
fender
covers
will
protect
the
finish
from
scratches
and
other
damage
.
Make
sure
the
car
is
relatively
clean
so
thatdi
rt
under
the
cover
does
not
scratch
the
finish
.
Any
repair
job
will
be
less
troublesome
if
the
parts
are
clean
.
For
cleaning
old
parts,
there
are
many
solvents
and
parts
cleaners
commercially
available
.
For
cleaning
parts
priorto
assembly,
commercially
available
aerosol
cans
of
parts
cleaner
or
brake
cleaner
are
handy
to
use,
and
the
cleaner
will
evaporate
completely
.
WARNING
-
Virtually
all
solvents
used
for
cleaning
parts
are
highly
flammable,
especially
in
aerosol
form
.
Use
wíth
extreme
care
.
Do
not
smoke
.
Do
not
use
these
products
near
any
source
of
heat,
sparksor
flame
.
Let
any
solvent
orcleaning
product
dry
completely
.
Low-
pressure,
dry
compressed
air
is
helpful
if
available
.
Also,
use
only
lint-free
rags
for
cleaning
and
drying
.

Windshield
Wiper
Biade
Maintenance
Common
problems
with
the
windshield
wipers
include
streaking
or
sheeting,
water
drops
after
wiping,
and
blade
chat-
ter
.
Streaking
is
usually
caused
when
wiper
blades
are
coated
with
road
film
or
car
wash
wax
.
Clean
the
blades
using
soapy
water
.
If
cleaning
theblades
does
not
cure
the
problem
then
they
should
be
replaced
.
BMW
recommends
replacing
the
wip-
er
blades
twice
a
year,
before
and
after
the
cold
season
.
Onold-
er
cars,
check
the
tension
spring
that
holds
the
wiper
to
the
glass
.
Replace
the
wiper
arm
if
the
springs
are
weak
.
Drops
that
remainbehind
after
wipingare
caused
by
oil,
road
film,
or
diesel
exhaust
coating
the
windshield
.
Use
an
alcohol
or
ammonia
solution,
or
a
non-abrasive
cleanser
to
clean
the
windshield
.
Wiper
blade
chatter
may
be
caused
by
dirty
or
worn
blades,
bya
dirty
windshield,
or
by
bentor
twisted
wiper
arms
.
Clean
the
blades
and
windshield
as
described
above
.
Adjust
the
wiper
arm
so
that
there
is
even
pressure
along
the
blade,
and
so
that
the
blade
is
perpendicular
to
the
windshield
atrest
.
Lubricate
the
wiper
linkage
with
a
light
oil
.
The
linkage
is
located
under
the
hood
on
the
drivers
side
.
If
the
problem
persists,
theblades
are
excessively
aged
or
worn
and
should
be
replaced
.

and

Lubricate
the

If

lubricate
them

The

The

be
kept
to
an
ab-
solute
minimum,
as
the
alcohol
in
the

out
of

and
may
cause

apply

washed
and
dried
.
Use
carnauba
or
synthetic
based
products
.
Waxing
is
not

after

.
You
can
tell
when
waxing
is
required
by
looking
at
the
finísh
when
it
is
wet
.
If
the
water
coats
the
paint
in
smooth
sheets
instead
of
forming
beads
that
rol¡

a

coat
of
wax
is

Wax

can
beused
to

On
