Engine: Service Precautions

Important: Follow the engine service information below. This information is important in order to prevent damage and in contributing to reliable engine performance.
In order to avoid damage to the engine oil pan, use a block of wood between the jack and the oil pan. Ensure that the block of wood extends past the complete width of the oil pan. Due to the small clearance between the oil pan and the oil pump screen, jacking against the oil pan may cause the oil pan to bend against the pump screen. This condition results in a damaged oil pick-up unit.

Caution: Refer to Battery Disconnect Caution in Service Precautions.

When working on the engine, remember that the 12 volt electrical system is capable of causing short circuits. When performing any work where electrical terminals may possibly be grounded, disconnect the ground cable of the battery at the battery. Any time you remove the air cleaner, cover the intake opening. This procedure protects against the accidental entrance of foreign material. Foreign material may follow the intake passage into the cylinder. This condition causes extensive damage when you start the engine.

General Information on Engine Service

Caution: Before removing or installing any electrical unit, or when a tool or equipment could easily come in contact with "live" or "hot all the times" exposed electrical terminals, disconnect the negative battery cable to help prevent personal injury and/or damage to the vehicle or components. Unless instructed otherwise, the ignition switch must be in the OFF or LOCK position.

Notice: The following information on engine service should be noted carefully, as it is important in preventing damage and contributing to reliable engine performance.

When you raise or support the engine for any reason, do not use a jack under the oil pan. Due to the small clearance between the oil pan and the oil pump screen, jacking against the oil pan may cause the oil pan to bend against the oil pump screen. This condition results in a damaged oil pump screen or oil pump pipe.

Any time you remove the throttle body or the air induction tube, cover the intake opening. This procedure protects against the accidental entrance of foreign material. Foreign material may follow the intake passage into the cylinder. This condition causes extensive damage when you start the engine.
