WARNING!

Do not re-use any fasteners that are worn or
deformed in normal use.
Some fasteners are designed to be used only
once, and are unreliable and may fail if used
again. This includes, but is not limited to,
nuts, bolts, washers, circlips and cotter pins.
Always follow the recommendations in this
manual-replace these fasteners with new
parts where indicated, and any other time it
is deemed necessary by inspection.

CAUTION!
If large quantities of metal particles or other
deposits (caused, i.e. by partial seizure of the
crankshaft or connecting rod bearings) are
found in engine oil, thoroughly clean oil
passages and replace oil cooler to prevent
damage from re-occuring.
Do not overfill with oil past the MAX mark on
the oil dipstick. Damage to the Three Way
Catalytic Converter (TWC) could result.
