Repair procedures

Removal

Engine removal is not required for this procedure.

•	Use fender covers to avoid damaging painted surfaces.

•	To avoid damage, unplug the wiring connectors carefully while holding the connector portion.

Mark all wiring and hoses to avoid misconnection.

1.	Remove the engine cover. (Refer to Engine And Transaxle Assembly - "Engine Cover")

2.	Disconnect the battery negative terminal.

3.	Remove the RH side front wheel. (Refer to Suspension System - "Wheel")

4.	Remove the engine room under cover. (Refer to Engine and Transaxle Assembly - "Engine Room Under Cover")

5.	Drain the coolant. (Refer to Cooling System - "Coolant")

6.	Drain the engine oil. (Refer to Lubrication System - "Engine Oil")

7.	Remove the drive belt. (Refer to Drive Belt System - "Drive Belt")

8.	Remove the alternator. (Refer to Engine Electrical System - "Alternator")

9.	Remove the drive belt tensioner. (Refer to Drive Belt System - "Drive Belt Tensioner")

10.	Remove the water pump. (Refer to Cooling System - "Water Pump")

11.	Remove the crankshaft damper pulley. (Refer to Drive Belt System - "Crankshaft Damper Pulley")

12.	Remove the cylinder head cover. (Refer to Cylinder Head Assembly - "Cylinder Head Cover")

13.

Remov ethe engine mounting support bracket.

(1)

Install the jack to the edge of ladder frame to support the engine.

Insert the rubber block between jack and ladder frame.

(2)	Disconnect the engine ground cable (A).

(3)

Remove the engine mounting support bracket (A).

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.)

Installation

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.

Tightening torque

A : 18.6 - 23.5 N·m (1.9 - 2.4 kgf·m, 13.7 - 17.4 lb·ft) -5EA

B : 44.1 - 53.9 N·m (4.5 - 5.5 kgf·m, 32.5 - 39.8 lb·ft) -3EA

C : 9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft) -8EA

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

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.

3.	Install the other parts in the reverse order of removal.
