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 [LF].)
1. Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [LF].)
2. Remove the air cleaner. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [LF].)
3. Disconnect the ventilation hose. (See QUICK RELEASE CONNECTOR (EMISSION SYSTEM) REMOVAL/INSTALLATION [LF].)
4. Loosen the water pump pulley bolt and removal the drive belt. (See DRIVE BELT REPLACEMENT [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 [LF].)
7. Disconnect the OCV connector.
8. Remove the ignition coils. (See IGNITION COIL REMOVAL/INSTALLATION [LF].)
9. Remove the drive belt. (See DRIVE BELT REPLACEMENT [LF].)
10. Remove the under cover. (See TRANSVERSE MEMBER REMOVAL/INSTALLATION.)
11. Remove the CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [LF].)
12. Remove the P/S oil pump with the oil hose still connected and position the P/S oil pump so that it is out of the way. (See POWER STEERING OIL PUMP REMOVAL/INSTALLATION.)
13. Move the cooler pipe No.3 and heater pipe slightly out of the way.
14. Remove in the order indicated in the table.
15. Install in the reverse order of removal.
16. Start the engine and:
Verify the ignition timing, idle speed and idle mixture. (See ENGINE TUNE-UP [LF].)
17. Perform a road test.

1. Remove the cylinder block lower blind plug.
2. Install the SST.
3. Turn the crankshaft clockwise until the crankshaft is in the No.1 cylinder TDC position (until the balance weight contacts the SST).
4. Hold the crankshaft pulley by using the SSTs.
5. Remove the crankshaft pulley lock bolt.
1. Remove the oil seal using a screwdriver as shown.
1. Using a thin screwdriver, hold the chain tensioner ratchet lock mechanism away from the ratchet stem.
2. Slowly compress the tensioner piston.
3. Hold the tensioner piston using a 1.5 mm {0.059 in} wire or paper clip.
1. Temporarily install the crankshaft pulley and crankshaft pulley lock bolt to the crankshaft, and lock the oil pump against rotation as shown in figure.
2. Remove the oil pump sprocket, and then remove the crankshaft pulley and crankshaft pulley lock bolt.
1. Temporarily install the crankshaft pulley and crankshaft pulley lock bolt to the crankshaft, and lock the oil pump against rotation as shown in figure.
2. Install the oil pump sprocket, and then remove the crankshaft pulley and crankshaft pulley lock bolt.Tightening torque
20—30 N·m {2.1—3.0 kgf·m, 14.8—22.1 ft·lbf}
1. Install the SST to the camshaft as shown.
2. Install the timing chain.
3. Remove the retaining wire or paper clip from the chain tensioner to apply tension to the timing chain.
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.
