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 cleaner outlet hose, throttle
body, surge tank pipe, intake collector or intake manifold is
removed, the intake opening should be covered. This will
protect against accidental entrance of foreign material which
could follow intake passage into cylinder and cause exten-
sive damage when engine is started.
• When disconnecting couplers, don’t pull wire harness but
make sure to hold coupler itself. With lock type coupler, be
sure to unlock before disconnection. Attempt to disconnect
coupler without unlocking may result in damage to coupler.
When connecting lock type coupler, insert it till clicking
sound is heard and connect it securely.
