Removal
TIMING CHAIN
Before installation, wipe off the protruding sealant.
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 crankshaft position sensor (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.
4. Remove ornament cover.
5. Remove air duct to intake manifold, collector, PCV hose, vacuum hoses, fuel hoses, wires, harness, connectors and so on.
6. Remove the following.
- Water hoses
- EVAP canister purge hose
- PCV hose
- PCV valve
- Water outlet
7. Remove intake manifold upper and lower collectors loosening bolts and nuts in reverse order of tightening.
8. Remove RH and LH ignition coils.
9. Remove fuel tube assembly.
10. Remove intake manifold loosening bolts and nuts in reverse order of tightening.
11. Remove RH and LH intake valve timing control solenoid valves.
12. Remove RH and LH rocker covers from cylinder head.
Loosen bolts in numerical order shown in the figure.
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 crankshaft position sensor (POS).
18. Set No. 1 piston at TDC on the compression stroke by rotating crankshaft.
Check that intake and exhaust cam nose on No. 1 cylinder are installed as shown. If not, turn the crankshaft one revolution (360°) and align as above.
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 intake valve timing control valve covers.
Loosen bolts in reverse order shown in the figure.
In the cover, the shaft is engaged with the center hole of the intake camshaft sprocket. Remove it straight out until the engagement comes off.
22. Remove air conditioner compressor and bracket.
23. Remove front exhaust tube and its support.
24. Hang engine at right and left side engine slingers with a suitable hoist.
25. Remove right side engine mounting, mounting bracket and nuts.
26. Remove center member assembly.
27. Remove upper and lower oil pans.
28. Remove water pump cover.
29. Remove front timing chain case bolts.
Loosen bolts in reverse order shown in the figure.
30. Remove front timing chain case.
Do not scratch sealing surfaces.
31. Remove timing chain tensioner cover from front timing chain case.
32. Remove front oil seal from front timing chain case.
33. Remove internal chain guide.
34. Remove timing chain tensioner and slack side chain guide.
Remove chain tensioner as follows.
a. Pull lever down, and release plunger stopper tab.
Plunger stopper tab can be pushed up to release (coaxial structure with lever).
b. Insert stopper pin into tensioner body hole to fix lever, and keep the tab released.
In figure, Allen wrench [2.5 mm (0.098 inch)] is used for stopper pin as an example.
c. Insert plunger into tensioner body by pressing slack guide.
d. Keep slack guide pressed, and fix it by pushing stopper pin through lever hole and body hole.
e. Remove mounting bolts, and remove chain tensioner.
35. Attach a suitable stopper pin to RH and LH camshaft chain tensioners. (For secondary timing chains)
36. Remove intake and exhaust camshaft sprocket bolts.
Apply paint to timing chain and camshaft sprockets for alignment during installation.
Secure the hexagonal portion of the camshaft using a spanner to loosen mounting bolts.
37. Remove primary and secondary timing chains with camshaft sprockets.
Intake camshaft sprocket is two-for-one structure of primary and secondary sprockets.
Handle intake camshaft sprocket, taking care of the following.
CAUTION: Avoid impact.
Do not disassemble (Never loosen bolts A and B).
38. Remove chain tension guide and crankshaft sprocket.
39. Remove rear timing chain case as follows.
a. Loosen mounting bolts in reverse order shown in figure, and remove them.
b. Disconnect liquid gasket applied portion using seal cutter (special service tool: KV101 11100) or an equivalent tool. Then remove rear timing chain case.
CAUTION: Do not remove plate metal cover of oil passage.
After removing chain case, do not apply any load which affects flatness.
40. Use a scraper to remove all traces of liquid gasket from front and rear timing chain case, and opposite mating surfaces.
Remove old liquid gasket from the bolt hole and thread.
41. Use a scraper to remove all traces of liquid gasket from water pump cover and intake valve timing control solenoid valve covers.
