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.	Disconnect the battery negative terminal.

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

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

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

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

6.	Remove the water pump pulley and then remove the water pump. (Refer to Cooling System - "Water Pump")

7.	Remove the idler. (Refer to Timing System - "Idler")

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

9.	Remove the crankshaft damper pulley. (Refer to Timing System – "Crankshaft Damper Pulley")

10.	Remove the intake oil control solenoide (OCS) (A), exhaust oil control solenoide (OCS) (B).

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

12.	Remove the engine mounting support bracket. (Refer to Engine and Transaxle Assembly - "Engine Mounting")

13.

Remove the timing chain cover (A) by gently prying the gaps between the cylinder head and cylinder block.

•	Be careful not to damage the contact surfaces of cylinder block, cylinder head and timing chain cover.

Installation

Install the timing chain cover (A).

(1)	Using a gasket scraper, remove all the old packing material from the gasket surfaces.

(2)	The sealant locations on the chain cover and the counter parts (cylinder head, cylinder block) must be free of harmful foreign materials, oil, dust and moisture. Spraying cleaner on the surface and wiping with a clean duster.

(3)

Before assembling the timing chain cover, liquid sealant should be applied on the gap between cylinder head and cylinder block.

Bead width : 3.0 - 5.0 mm (0.11 - 0.20 in.)

Sealant : MS721 - 40 AA

(4)

After applying liquid sealant on the timing chain cover, assemble the cover within 5 minutes after sealant was applied. Continuous bead of sealant should be applied to prevent any path from oil leakage.

Bead width

2.5 - 3.5 mm (0.09 - 0.13 in)

Sealant : MS721-40 AA or AAO

(5)

Install the timing chain cover. 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 in exact position.

Tightening torque

A : 28.4 - 31.3 N.m (2.9 - 3.2 kgf.m, 20.9 - 23.1 lb-ft)

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

C : 44.1 - 53.9 N.m (4.5 - 5.5 kgf.m, 32.5 - 39.8 lb-ft)

•	Do not reuse the seal bolt (D).

•	The engine running or pressure test should not be performed within 30 minutes after the timing chain cover was assembled.

2.	Replace the front oil seal if necessary. (Refer to Timing System - "Front Oil Seal")

3.	Install the engine mounting support bracket. (Refer to Engine and Transaxle Assembly - "Engine Mounting")

4.	Install the cylinder head cover. (Refer to Cylinder Head Assembly - "Cylinder Head Cover")

Install the intake oil control solenoide (OCS) (A), exhaust oil control solenoide (OCS) (B).

Tightening torque :

9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)

•	Do not reuse the oil control solenoide (OCS) O-ring (A).

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