ENGINE REMOVAL/INSTALLATION [LF, L5]

Warning
•  Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.
•  Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line Safety Procedure”. (See BEFORE SERVICE PRECAUTION [LF, L5].)
•  Secure the steering wheel using tape or a cable to prevent the steering shaft from rotating after disconnecting the steering shaft. If the steering wheel rotates after the steering shaft and the steering gear and linkage are disconnected, the internal parts of the clock spring could be damaged.
Caution
L5
•  If the crankshaft and the cylinder block are replaced with a type B from a type A as shown in the figure, perform PCM reprogramming. Otherwise, the engine could be damaged. (See PCM REPROGRAMMING [LF, L5] .)
