Tightening torque
Nut (B):
88.2 - 107.8 N·m (9.0 - 11.0 kgf·m, 65.1 - 79.5 lb·ft)
Bolt and Nuts (C):
58.8 - 73.5 N·m (6.0 - 7.5 kgf·m, 43.3 - 57.2 lb·ft)
|

|
|
14. |
Remove the variable force solenoid (VFS) valve (A).

|
15. |
Remove the timing chain cover (A).

Remove thoroughly sealant and oil etc left at the sealing surface
after remove the chain cover and oil pan. (If any impurities are
left at the sealing face, oil may leak after reassembly even with
the sealant application.)
|
|
1. |
Install the timing chain cover.
(1) |
The sealant locations on chain cover and on counter parts (cylinder
head, cylinder block) must be free of engine oil and etc.
|
(2) |
Before assembling the timing chain cover, the liquid sealant
MS721-40AA should be applied on the gap between cylinder head and
cylinder block.
The part must be assembled within 5 minutes after sealant was
applied.
Bead width : 4.0 mm (0.16 in.)
|

|
(3) |
Before assembling the timing chain cover, The liquid sealant
TB 1217H should be applied on chamfer of timing chain cover. Equivalent
to TB1282B or equivalent to TB1216E for groove of water pump. The
part must be assembled within 5 minutes after the sealant was applied.
Sealant should be applied in a continuous bead in each of the
areas indicated below.
Bead width :
A : 2.5 - 3.5 mm (0.09 - 0.14 in.)
B : 1.5 - 2.5 mm (0.06 - 0.10 in.)
C : 4.5 - 5.5 mm (0.18 - 0.22 in.)
D : 3.5 - 4.5 mm (0.14 - 0.18 in.)
|

During timing cover installation, care not to take off
applied sealant on the timing cover by contact with other
parts.
|
|
(4) |
The dowel pins on the cylinder block and holes on the timing
chain cover should be used as a reference in order to assemble the
timing chain cover correctly.

-8EA
D : 18.6 - 23.5 N·m (1.9 - 2.4 kgf·m, 13.7 - 17.4 lb·ft)
-1EA
|

|
|
2. |
Install the variable force solenoid (VFS) valve (A).
Tightening torque :
7.8 - 11.8 N·m (0.8 - 1.2 kgf·m, 5.8 - 8.7 lb·ft)
|

Do not use any dropped variable force solenoid (VFS) valve.
