CHANGE
1. Draining the Oil Sump. Discharge
the
used
oil
through
the
sump
drain hose (attached
to
the
front
of
the
engine)
while the
engine
is
warm.
Drain
the
used
oil
completely,
replace
the
hose in
its
bracket, and replace
the
end
cap
securely.
NOTE:
Thread
size
for
the
lube
oil
drain
hose
capped end
is
JI4NPT.
Always
observe the
used
oil
as
it
is
removed.
A
yellow/gray emulsion indicates the presence of
water
in
the
oil.
Although
this
condition
is
rare, it
does
require
prompt attention to prevent serious
damage.
Call a
qualified mechanic should water be present in
the
oil.
Raw
water present in
the
oil
can
be
the
result of a fault in
the exhaust system attached
to
the engine and/or a
siphoning of
raw
water
through
the
raw
water cooling
circuit into the exhaust,
filling
the
engine.
This
problem
is
often caused by
the
absence
of
an
anti-siphon
valve,
its
poor location
or
lack
of
maintenance.
1.
Replacing the Oil Filter. When removing
the
used
oil
filter,
you
may
find
it helpful
and
cleaner
to
punch
a
hole
in
the upper
and
lower portion of the
old
filter
to
drain
the oil
from
it into a container before removing
it.
This
helps
to
lessen spillage. A small automotive
filter
wrench
should
be
helpful
in
removing the old
oil
filter.
NOTE:
Do not punch
this
hole
without jirst
loosening
the
filter
to
make
certain it
can
be
removed.
Place some paper
towels
and
a plastic bag
around
the
filter
when
unscrewing
it
to
catch
any
oil
left
in
the
filter.
(Oil
or
any
other
fluid
on
the
engine
reduces
the
engine's
cooling
ability.
Keep
your engine clean.) Inspect the
old
oil
filter
as
it
is
removed
to
make
sure that
the
rubber
sealing
gaSket
comes
off with
the
old oil
filter.
If
this
rubber sealing gasket remains sealed against
the
filter
bracket, gently remove
it.

When installing
the
new
oil
filter element, wipe
the
filter
gasket's sealing surface
on
the bracket
free
of oil and
apply
a
thin
coat
of
clean engine
oil
to
the
rubber gasket
on
the
new
oil
filter.
Screw
the filter onto
the
threaded
oil
filter
nipple on
the
oil
filter bracket, and
then
tighten the
filter
firmly
by
hand.
NOTE:
The
engine oil
is
cooled by
engine
coolant flowing
through
passages
in
the
oil
filter bracket
housing
assembly.
A
WARNING:
Used
engine
oil
contains
harmful
contaminants.
Avoid
prolonged
skin
contact.
Clean
skin
and
nails
thoroughly
using
soap
and
water.
Launder
or
discard
clothing
or
rags
containing
used
oil.
Discard
used
oil
properly.
NOTE:
Generic filters
are
not
recommended,
as
the
material standards or diameters
of
important items
on
generic
parts might
be
entirely different from genuine
parts.
Immediately after
an
oil filter change and oil
fill,
run
the
engine
to
make
sure
the
oil pressure
is
normal
and
that
there
are
no
oil leaks around
the
new
oil
jilter.
3.
Filling the Oil Sump. Add
new
oil
through
the
oil
filler
cap
on
the
top
of the engine
or
through
the
side
oil
fill.
After refilling,
run
the
engine for a
few
moments
while
checking
the
oil
pressure. Make sure there
is
no
leakage
around
the
new
oil
filter
or from
the
oil
drain
system,
and
stop
the
engine.
Then check
the
quantity of
oil
with
the
lube
oil
dipstick. Fill to, but not over the high mark
on
the
dipstick,
should
the
engine require additional
oil.
