General Information on Engine Service
THE FOLLOWING INFORMATION ON ENGINE SERVICE
SHOULD BE NOTED CAREFULLY, AS IT IS IMPORTANT IN
PREVENTING DAMAGE, AND IN CONTRIBUTING TO RELI-
ABLE ENGINE PERFORMANCE.
• When raising or supporting engine for any reason, do not
use a jack under oil pan. Due to small clearance between oil
pan and oil pump strainer, jacking against oil pan may cause
it to be bent against strainer resulting in damaged oil pick-up
unit.
• It should be kept in mind, while working on engine, that 12-
volt electrical system is capable of violent and damaging
short circuits. When performing any work where electrical
terminals could possibly be grounded, ground cable of the
battery should be disconnected at battery.
• Any time the air cleaner, air intake pipe, throttle body or
intake manifold is removed, the intake opening should be
covered. This will protect against accidental entrance of for-
eign material which could follow intake passage into cylinder
and cause extensive damage when engine is started.
