drain plug. Use a container that can hold at
least 15 U.S. quarts (14,2 liters) of oil.
Warning
• Hot oil can cause personal injury.
• Avoid prolonged and repeated skin contact
with used engine oils. Such prolonged and
repeated contact may cause serious skin
disorders or other serious bodily injury.
Avoid excessive contact, wash thoroughly
after contact, and keep engine oil out of the
reach of children.

oil pan and allow oil to drain completely into
receptacle.
IMPORTANT: Protect the environment. Handling
and disposal of used engine oil may be subject to
federal, state and local laws and regulations. Use
authorized waste disposal facilities, including civic
amenity sites and garages providing authorized
facilities for used oil. If in doubt, contact your state
and local environmental authorities or the Environ-
mental Protection Agency for guidance as to
proper handling and disposal of used engine oil.

head. Make sure it is removed.
NOTE: The Turbo Engine has an oil cooler which
is mounted between the filter head and oil filter
element. Before fitting a replacement filter ele-
ment, the retaining adaptor screw should be
checked for tightness, Fig. 8A.9.
