Engine Oil Change (to
include
fiHer)
1.
Draining the Oil Sump
Remove the oil drain hose from its attachment
bracket and lower it into a container and allow the
oil
to
drain, or attach a pump
to
the end of the drain
hose and pump the old oil out. Make sure the oil
drain hose
is
properly secured
in
its holder after all
of the old oil has been drained.
Always observe the old oil as it is removed. A yel-
low/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 competent mechanic should
water be present in the oil.
Sea water present in
the oil can be the result of a fault in the exhaust
system attached
to
the engine and/or a siphoning
through the sea water
cooling circuit into the ex-
haust, filling it up into the engine (refer
to
the in-
stallation illustrations on page
21
and 22).
2.
Replacement of 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 style automotive
filter wrench should be helpful in removing the old
oil filter. 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.
Please keep your engine clean.)
Inspect the old oil
filter as it is removed
to
make sure that the rubber
sealing gasket came off with the old oil filter. If this
rubber
sealing gasket remains sealed against the
engine block, gently remove
it.
The replaceable
cartridge-type oil filter requires no cleaning inside,
so it may be properly disposed of.
When installing the new oil filter element, wipe the filter gasket's sealing surface on the engine block free of
oil and apply a thin coat of clean engine oil
to
the rubber gasket on the oil filter. Screw the filter onto the
threaded
oil
filter stub, and then tighten the filter firmly
by
hand.
NOTE: Generic filters are not recommended, as the material standards or diameters of im-
portant 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 filter.
