Insert the blade of SST(09215-3C000) between the upper oil pan and lower oil pan. Cut off applied sealer and remove the lower oil pan.





NOTE:
- Insert the SST between the oil pan and the ladder frame by tapping it with a plastic hammer in the direction of arrow.
- After tapping the SST with a plastic hammer along the direction of arrow around more than 2/3 edge of the oil pan, remove it from the ladder frame.
- Do not use the SST as a prybar. Hold the tool in position (on the gasket line) and tap in with a light hammer.
- Be careful not to damage the contact surfaces of Upper oil pan and lower oil pan.

12. Install the jack to the edge of ladder frame (A) to support the engine.





NOTE:
Insert the rubber block between jack and ladder frame.

13. Disconnect the ground cable (A), and then remove the engine mounting bracket (B).




14. Remove the surge tank (A).





NOTE:
Cover the inlet of intake manifold with a clean woven stuff or vinyl cover to prevent foreign materials from entering.

15. Disconnect the RH ignition coil connectors (A) and the RH injector connectors (B).




16. Remove the LH/RH ignition coils (A).








17. Remove the exhaust OCV cap (A), and then remove the LH, RH cylinder head covers.




18. To release the tension, turn the drive belt tensioner counterclockwise then remove the drive belt (A).




19. Lift up the engine assembly by using the jack.
20. Remove the power steering pump (A).




21. Remove the air conditioner compressor (A).




22. Remove the alternator (A).




23. Remove the drive belt idler (A).




24. Remove the drive belt auto tensioner (A).




25. Remove the water pump pulley (A).




26. Set No.1 cylinder to TDC/compression.
(1) Turn the crankshaft pulley clockwise and align its groove with the timing mark "T" of the lower timing chain cover.




(2) Check that the mark (A) of the camshaft timing sprockets are in straight line on the cylinder head surface as shown in the illustration. If not, turn the crankshaft clockwise one revolution (360°).









NOTE:
Do not rotate engine counterclockwise.

27. Remove the crankshaft pulley (A).





NOTE:
There are two methods to hold the ring gear when installing or removing the crankshaft damper pulley.
- Install the SST (09231-2B100) to hold the ring gear after removing the starter.




- Install the SST (09231-3D100) to hold the ring gear after removing the dust cover.
1. Remove the front muffler.
2. Remove the dust cover (A) on the bottom of the upper oil pan and unfasten the two transaxle mounting bolts (B).




3. Adjust the length of the holder nuts (A) so that the front plate of the holder (B) puts in the ring gear (C) teeth.
4. Fasten the two transaxle mounting bolts in the original mounted holes.

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

NOTE:
Before removing the timing chain, mark the RH/LH timing chain with an identification based on the location of the sprocket because the identification mark on the chain for TDC (Top Dead Center) can be erased.
















30. Remove the oil pump chain cover (A).




31. Remove the oil pump chain tensioner assembly (A).




32. Remove the oil pump chain guide (A).

Inspection

Sprockets, Chain Tensioner, Chain Guide, Chain Tensioner Arm
1. Check the camshaft sprocket and crankshaft sprocket for abnormal wear, cracks, or damage. Replace as necessary.
2. Inspect the tensioner arm and chain guide for abnormal wear, cracks, or damage. Replace as necessary.
3. Check that the tensioner piston moves smoothly when the ratchet pawl is released with thin rod.

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