4.

NOTE: Mark the direction of travel of the drive belt.

Remove the accessory drive belt.

• 1.Loosen the bolts on the coolant pump pulley.
• 2. Turn the tensioner clockwise.
• 3. Disconnect the accessory drive idler pulley.
• Disconnect the coolant pump pulley.

5. Remove the crankshaft pulley.




6.

CAUTION: To avoid damage to the timing belt, the lower portion of the front engine cover must be removed.

Disconnect the lower timing belt cover.



7. Lower the vehicle.

8. Disconnect the expansion tank of the cooling system and place it aside.



9. Disconnect the power steering fluid reservoir and place it aside.




10.

CAUTION: Place a suitable block of wood between the oil pan and the trolley jack.

Place a trolley jack and a wooden block under the oil pan and raise the engine enough to relieve the load on the front engine mount.

11.

NOTE: Mark the position of the front engine mount.

Remove the front engine mount.



12. Disconnect the upper timing belt cover. Leave the timing belt cover in its installed position.



13. Remove the front engine mount bracket. Remove the upper timing belt cover.




14. Remove the spark plug cover.



15.

CAUTION: Do not pull on the wire when disconnecting the spark plug connectors. If necessary, disconnect the ignition wires from the ignition coil to prevent twisting. To release the seal, slightly twist the spark plug connectors before disconnecting them.

CAUTION: Disconnect the spark plug connectors according to the spark plug order.

NOTE: Release sequence: from outside to inside, working in a criss-cross pattern.

Remove the cylinder head cover.

• 1. Disconnect the spark plug connectors.
• 2. Disconnect the positive crankcase ventilation (PCV) hose.
• 3. Unscrew ten bolts.

16. Remove the spark plugs.




17.

NOTE: The engine should only be turned in the normal direction of crankshaft rotation.

Turn the engine until piston No.1 reaches the top dead center (TDC) position.

18. Loosen the timing belt tension (for clarity, the timing belt is shown removed).

• 1. Loosen the bolt four turns.
• 2. Position the tensioner so that the locking element is located approximately at the 4 o'clock position.
• 3. Align the Allen key slot in the tensioner adjusting washer with the pointer located behind the pulley.

19. Remove the timing belt.

20.

NOTE: Use an open-end wrench to prevent the camshaft from turning.

Remove the intake camshaft pulley plug.



21.

NOTE: Use an open-end wrench to prevent the camshaft from turning.

Loosen the camshaft pulley mounting bolts.

Installation

1.

NOTE: Do not tighten the bolts. The pulleys must be able to turn freely on the camshafts.

Turn the camshafts to the ignition position for cylinder No.1 and insert the special tool into the camshafts.



2.

NOTE: The engine should only be turned in the normal direction of crankshaft rotation.

Turn the crankshaft to top dead center position for cylinder No.1.



3. Remove the plug, install the special tool.



4.

CAUTION: Do not twist the timing belt (the timing belt bend diameter must not be less than 35 mm).

CAUTION: Do not rotate the crankshaft; make sure it still rests against the alignment pin.

NOTE: When installing the timing belt, the tab on the belt tensioner should not be suspended from the sheet metal cover.

Install the new timing belt. Starting at the crankshaft pulley and working counterclockwise, slide the timing belt on, keeping it taut.



5.

CAUTION: Incorrect timing belt tension will result in incorrect valve timing.

Pre-tighten the timing belt.

• 1. Turn the tensioner locking element counterclockwise and insert the locking element into the groove on the timing cover.
• 2. Position the Allen key slot in the tensioner adjusting washer at the 4 o'clock position.
• 3.Using a 6mm Allen key, tighten the bolt just enough to pull the tensioner toward the rear timing cover, but still allow the tensioner adjusting shim to rotate.

6.

CAUTION: Tighten the timing belt by turning counterclockwise.

Using the Allen key, turn the adjusting washer counterclockwise until the mark on the pointer is centered with the index line on the stopper (the pointer will move clockwise as you adjust).



7. Tighten the bolt while holding the adjusting washer in place.



8.

NOTE: Use an open-end wrench to prevent the camshaft from turning.

Tighten the camshaft pulley mounting bolts.



9.

NOTE: Use an open-end wrench to prevent the camshaft from turning.

Install the intake camshaft pulley plug.



10. Remove the special tool.



11. Remove the special tool from the camshafts.

12.

NOTE: Rotate the crankshaft two revolutions in the direction of normal rotation.

Check the valve timing by installing a special tool. Correct them if necessary.

• Install the special tool and make sure it contacts the crankshaft.
• Install the special tool into the camshafts; if necessary, loosen the pulleys and adjust the camshaft alignment.
• Remove special tools.

13. Install the special tool.



14.

CAUTION: To avoid damaging the spark plug connectors, use a blunt-ended object (plastic tie) to apply silicone grease.

CAUTION: When mating the spark plug connector, keep it in line with the spark plug.

NOTE: Apply silicone grease to a depth of 5-10 mm to the inside of the spark plug connectors.

Install the cylinder head cover.

• 1. Tighten the bolts in two stages. Stage 1: 2 Nm. Stage 2: 7 Nm
• 2. Secure the PCV hose to the valve cover. Connect the VCT actuator plug connector.
• 3. Apply a grease such as anti-seize lubricant to the spark plug threads, screw in the spark plugs, and connect the spark plug connectors.

15. Install the spark plug cover.



16.

Note: Install the top cover of the gas distribution belt and the center belt of the gas distribution mechanism.

Install the front engine mount bracket.



17.

NOTE: Check the position of the upper timing belt cover gasket and adjust it if necessary.

Install the upper timing belt cover.



18. Install the front engine mount.



19. Install the power steering pump reservoir.



20. Secure the expansion tank of the cooling system.



21. Remove the trolley jack and wooden block.

22. Raise and support the vehicle. Refer to Section 100-02 for additional information.

23. Install the lower timing belt cover.



24. Install the crankshaft pulley.



25. Install the plug.



26.

NOTE: Direction of travel on used drive belt.

Install the drive belt.

• 1. Install the idler pulley of the poly V-belt. Install the coolant pump pulley. Do not tighten the bolts at this stage.
• 2. Put on the drive belt by turning it clockwise and tighten it.
• 3. Tighten the bolts on the coolant pump pulley.

27. Lower the vehicle.

28. Connect the ground cable to the battery. For additional information, refer to Section 414-01.
