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.

Note

• Perform the engine and transaxle component removal/installation from below the vehicle.

Engine Installation

Warning

• When removing/installing the engine, verify that the engine and transaxle are securely supported. Otherwise, the engine may fall off and cause serious injury or death, and damage to the vehicle.

Caution

• Slots have been adopted for the No.3 engine mount and No.4 engine mount bracket installation holes. Tighten the installation bolts and nuts so that they are centered on the slots. Otherwise, engine noise or vibration could increase.

Note

• Retighten the engine front cover and transaxle stud bolts when the nuts of No.3 engine mount and No.4 engine mount bracket are loosened.

1.Tighten the engine front cover stud bolts.

am6xuw00006690

2.Measure the projection of the transaxle stud bolts. (MTX)

• If the projection amount is not within the range, adjust the projection amount of the stud bolt.

am6xuw00011730

3.Tighten the transaxle stud bolts. (ATX)

am6xuw00012315

Caution

• When supporting the engine and transaxle, insert rubber of appropriate size (approx. 20 mm {0.79 in} thickness) between the engine lifter and the oil pan, transaxle to prevent the deformation of the oil pan and damage of the transaxle.

4.Secure the engine and transaxle using a commercially available engine lifter.
