Precautions for Engine Service

CAUTION:

If a jack is applied to the oil pan when raising or supporting the engine, the oil pan could be deformed or broken. Always use a chain hoist to support the engine by attaching the chain to the hooks on the engine.
If the 12 V electrical system is shorted while servicing the engine, the engine electrical circuits could be damaged seriously. When the intended service operation does not require electric power supply from the battery, be sure to disconnect the negative cable at the battery before starting the service work.
If foreign material has entered the engine during removal of intake system components, internal parts of the engine could be severely damaged when the engine is started. Be sure to suitably cover the air intake port when the air cleaner, throttle body, intake manifold or other intake system component is removed.
