  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 injures 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 [L8, LF].)

1. Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [L8, LF].)

2. Remove the air cleaner. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L8, LF].)

3. Disconnect the ventilation hose. (See QUICK RELEASE CONNECTOR (EMISSION SYSTEM) REMOVAL/INSTALLATION [L8, LF].)

4. Loosen the water pump pulley bolt and remove the drive belt. (See DRIVE BELT REPLACEMENT [L8, LF].)

5. Remove the front suspension tower bar (joint). (See FRONT SUSPENSION TOWER BAR REMOVAL/INSTALLATION.)

6. Remove the CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION [L8, LF].)

7. Disconnect the oil control valve (OCV) connector. (With variable valve timing mechanism.)

2. Install the timing chain.

3. Remove the retaining wire or paper clip from the chain tensioner to apply tension to the timing chain.

Engine Front Cover Installation Note

  Note
  • Install the front oil seal before performing the following procedure.

1. Apply silicone sealant to the engine front cover as shown.

  Caution
  • Install the engine front cover before the applied silicone sealant starts to harden.
  • Completely remove any oil, dirt, sealant, or other foreign matter adhering to the engine front cover and engine front cover installation surface. If any oil, dirt, sealant, or other foreign matter is not removed from the space between the engine front cover and engine front cover installation surface, it may cause a sealing malfunction.
