ENGINE REMOVAL/INSTALLATION [SKYACTIV-G 2.5T]


id0110q8800400

Warning
•  A hot engine can cause severe burns. Turn off the engine and wait until it is cool before servicing.
•  Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.
•  Highly pressurized fuel may spray out if the fuel line is cut.
Due to the following dangers occurring with a fuel spray, always complete the “Fuel Line Safety Procedure” to prevent the fuel from spraying.
?  Fuel may cause irritation if it comes in contact with skin and eyes.
?  If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities.
Caution
•  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.
•  Applying excessive force (force of 100 N {10.2 kgf, 22.5 lbf} or more) to the electric variable valve timing motor/driver may cause a malfunction. When servicing, be careful not to apply excessive force to the electric variable valve timing motor/driver using other parts or tools.
