  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 Fuel Line Safety Procedure.)

1. Remove the following parts.

  (1) Plug hole plate (See PLUG HOLE PLATE REMOVAL/INSTALLATION [LF].)
  (2) Plug hole plate bracket
  (3) Accelerator cable and bracket
  (4) Battery cover (See BATTERY REMOVAL/INSTALLATION [LF].)

2. Disconnect the negative battery cable.

3. Remove the following parts.

  (1) Ignition coils (See IGNITION COIL REMOVAL/INSTALLATION [LF].)
  (2) Front wheel and tire (RH) (See GENERAL PROCEDURES (SUSPENSION).)
  (3) Under cover and splash shields
  (4) Crankshaft position (CKP) sensor (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [LF].)
  (5) Drive belt (See DRIVE BELT REPLACEMENT [LF].)
  (6) A/C compressor with the oil hose still connected and position the A/C compressor so that it is out of the way (See A/C COMPRESSOR REMOVAL/INSTALLATION [LF].)
  (7) Coolant reserve tank with the hose still connected and position the coolant reserve tank so that it is out of the way

4. Remove in the order indicated in the table.

5. Install in the reverse order of removal.

6. Start the engine.
