Install the timing chain cover (A).
The sealant locations on chain cover and on counter parts (cylinder head, cylinder block) must be free of engine oil and etc.
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 : 4.0mm (0.16in.)
Before assembling the timing chain cover, The liquid sealant MS721-40AA 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 ~ 3.5mm (0.09 ~ 0.14in.)
B : 1.5 ~ 2.5mm (0.06 ~ 0.10in.)
C : 4.5 ~ 5.5mm (0.18 ~ 0.22in.)
D : 3.5 ~ 4.5mm (0.14 ~ 0.18in.)
During timing cover installation, care not to take off applied sealant on the timing cover by contact with other parts.
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.
