Part 1 of 2

Removal

CAUTION:
- Use fender covers to avoid damaging painted surfaces.
- To avoid damage, unplug the wiring connectors carefully while holding the connector portion.

NOTE:
Mark all wiring and hoses to avoid misconnection.

1. Disconnect the battery negative cable (A).




2. Loosen the drain plug (A) and drain the engine coolant.




3. Disconnect the breather hose (A), vacuum hose (B). And remove the air duct (C) and air cleaner assembly (D).




4. Remove the radiator upper hose (A).




5. Remove the intercooler outlet hose (B) after disconnecting the BPS connector (A).




6. Remove the intercooler inlet hose (A).




7. Disconnect the ignition coil connectors (A) and remove the ignition coils.
8. Remove the cylinder head cover (D) after removing the vacuum hoses (B) and PCV hose (C).




9. Set No.1 cylinder to TDC/compression.




10. Remove the drive belt (A), alternator (B) and power steering pump (C).




11. Remove the tensioner assembly (A), water pump assembly (B), idler (C) and crankshaft pulley (D).





NOTE:
Use the SST (crankshaft pulley adapter and holder, 09231-2M100,09231-2J210,) to remove the crankshaft pulley bolt.

12. Remove the lower oil pan using the SST (09215-3C000).





NOTE:
- Insert the SST between the oil pan and the ladder frame by tapping it with a plastic hammer in the direction of arrow #1.
- After tapping the SST with a plastic hammer along the direction of arrow #2 around more than 2/3 edge of the oil pan, remove it from the ladder frame.
- Do not turn over the SST abruptly without tapping. It be result in damage of the SST.
- Be careful not to damage the contact surfaces of Upper oil pan and lower oil pan.

13. Remove the timing chain cover (A).





CAUTION:
Be careful not to damage the contact surfaces of cylinder block, cylinder head and timing chain cover.

14. The key of crankshaft should be aligned with the mating face of main bearing cap. As a result of this, the piston of No.1 cylinder is placed at the top dead center on compression stroke.








15. Install a set pin after compressing the timing chain tensioner.




16. Remove the timing chain tensioner (A) and timing chain tensioner arm (B).




17. Remove the timing chain.
18. Remove the timing chain guide (A).




19. Remove the timing chain oil jet (A) and crankshaft sprocket (B).




20. Remove the balance shaft chain.


Inspection

Sprockets, Hydraulic Tensioner, Chain Guide, Tensioner Arm
1. Check the CVVT sprocket, crankshaft sprocket teeth for abnormal wear, cracks or damage. Replace if necessary.
2. Check a contact surface of the chain tensioner arm and guide for abnormal wear, cracks or damage. Replace if necessary.
3. Check the hydraulic tensioner for its piston stroke and ratchet operation. Replace if necessary.

Belt, Idler, Pulley
1. Check the idler for excessive oil leakage, abnormal rotation or vibration. Replace if necessary.
2. Check belt for maintenance and abnormal wear of V-ribbed part. Replace if necessary.
3. Check the pulleys for vibration in rotation, oil or dust deposit of V-ribbed part. Replace if necessary.
