For 1990-2009 cars only
| • | An engine is a combination of many machined, honed, polished, and lapped surfaces with very close tolerances. |
| • | Whenever you remove the valve train, the cylinder head, the crankshaft, or the connecting rod components for service, keep these parts in order. At the time of installation, install these components in the same locations, and with the same mating surfaces the parts had when you removed them. |
| • | When you remove the air cleaner, cover the intake opening. This protects against foreign material which could follow the intake passage into the cylinder. This could cause extensive damage when you start the engine. |
| • | Care and cleanliness are important when you service any internal engine parts. Apply a liberal coating of engine oil to friction areas during assembly. This protects and lubricates the surfaces during the initial operation. Proper cleaning and protection of machined surfaces and friction areas are part of the repair procedure. Consider this standard shop practice. |
| • | When you work on the engine, remember that 12-volt electrical
systems are capable of violent and damaging short circuits. When you perform
any work where electrical terminals could be grounded, disconnect the battery
ground cable at the battery. Disconnect the battery cables before you perform
any major work on the engine. Failure to disconnect the cables may result
in damage to the wiring harnesses or to other electrical parts. Refer to
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. in General Information. |
| • | Cover or otherwise protect exposed electrical connections in order to prevent damage from the fuel or the oil. |
| • | 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, using a jack against the oil pan may cause the oil pan to bend against the pump screen. This could cause damage to the oil pickup unit. Refer to Lifting and Jacking the Vehicle in General Information. |
