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: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

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.

In the mechanical procedures described in this section, generally no references will be made to the removal of optional equipment such as the power steering pump, the air conditioning compressor, etc.

If you need to remove any optional equipment in order to perform other service, refer to the appropriate section of this service manual for the specific information.
