Precautions on Engine Service
The following information on engine service should be noted carefully, as it is important in preventing damage, and in contributing to reliable 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 can be grounded, ground cable of the battery should be disconnected at battery.
Any time the air cleaner, throttle body 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 extensive damage when engine is started.
