Removal and Inspection

CAUTION:
- After removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike piston heads. When installing camshafts, chain tensioners, oil seals, or other sliding parts, lubricate contacting surfaces with new engine oil.
- Apply new engine oil to bolt threads and seat surfaces when installing cylinder head, camshaft sprockets, crankshaft pulley, and camshaft brackets.
- Before disconnecting fuel hose, release fuel pressure.
- When removing the oil pans, oil pump assembly and timing chain from engine, first remove the camshaft position sensor (PHASE) and the crankshaft position sensors (REF)/(POS) from the assembly. Be careful not to damage sensor edges.
- Do not spill engine coolant on drive belts.

REMOVAL
1. Drain engine oil.
2. Release fuel pressure.
3. Drain coolant by removing cylinder block drain plugs and radiator drain cock.
4. Remove left side ornament cover.
5. Remove air duct to intake manifold, collector, blow-by hose, vacuum hoses, fuel hoses, wires, harness, connectors and so on.





6. Remove the following.
- Vacuum hoses
- Water hoses
- EVAP canister purge hose
- Blow-by hose





7. Remove RH and LH ignition coils.





8. Remove EGR guide tube.





9. Remove intake manifold collector supports and intake manifold collector (RH cylinder head only).





10. Remove fuel tube assembly.
- Do not disassemble fuel tube assembly.





11. Remove intake manifold in reverse order of installation.





12. Remove RH and LH rocker covers from cylinder head.
13. Remove engine undercover.
14. Remove front RH wheel and engine side cover.
15. Remove drive belts and idler pulley bracket.





16. Remove power steering oil pump belt and power steering oil pump assembly.








17. Remove camshaft position sensor (PHASE) and crankshaft position sensors (REF)/(POS).





18. Set No. 1 piston at TDC on the compression stroke by rotating crankshaft.








19. Loosen crankshaft pulley bolt. (At this time remove oil pan rear cover plate and set a suitable tool to ring gear so that crankshaft cannot rotate.)
- Be careful not to damage the signal plate teeth.





20. Remove crankshaft pulley with a suitable puller.





21. Remove air compressor and bracket.

25. Remove center member assembly.
26. Remove upper and lower oil pans.





27. Remove water pump cover.





28. Remove front timing chain case bolts.
- Loosen bolts in numerical order as shown in the figure





29. Remove front timing chain case.
- Do not scratch sealing surfaces.





30. Remove internal timing chain guide.
31. Remove upper chain guide.
32. Remove timing chain tensioner and slack side chain guide.








33. Remove RH & LH camshaft sprocket 1st bolts.
34. Remove camshaft sprockets 1st. on both sides, crankshaft sprocket and timing chain.
- Apply paint to timing chain and camshaft sprockets 1ST for alignment during installation.





35. Attach a suitable stopper pin to RH and LH camshaft chain tensioners.





36. Remove exhaust camshaft sprocket 2ND bolts on both sides.
- Apply paint to timing chain and camshaft sprockets 2ND for alignment during installation.





37. Remove exhaust camshaft sprockets 2ND, intake camshaft sprockets 2ND and camshaft chains on both sides.





38. Remove lower chain guide.








39. Use a scraper to remove all traces of liquid gasket from front timing chain case.
- Remove old liquid gasket from the bolt hole and thread.





40. Use a scraper to remove all traces of liquid gasket from water pump cover.

INSPECTION





Check for cracks and excessive wear at roller links. Replace chain if necessary.
