Timing Belt: Service and Repair

REMOVAL
1. Disconnect negative cable at battery.
2. Hoist vehicle.





3. Remove clip after pushing center pin, and then remove fender apron extension on right side.

NOTE: Do not push center pin too far in, or it will fall off into fender.

4. Remove air cleaner assembly as previously outlined.
5. Remove A/C compressor drive belt, if equipped.
6. Loosen water pump pulley bolts.





7. Loosen generator pivot bolts and its adjusting bolt and remove water pump belt and its pulley.
8. Remove crankshaft pulley.





(1) Lock crankshaft to loosen crankshaft timing belt pulley bolt and crankshaft pulley bolts.

NOTE: To remove crankshaft pulley with engine assembly mounted on body, it is necessary to remove crankshaft timing belt pulley bolt. But if engine assembly is dismounted, bolt needs not be removed.





(2) Using special tool (17 mm socket), loosen crankshaft pulley bolts and timing belt pulley bolt, and remove crankshaft pulley.

Special Tool or equivalent (A): 09919-16020





9. Remove resonator and timing belt outside cover.





10. Align 4 timing marks as shown in figure to facilitate its installation.





11. Loosen tensioner bolt and stud, and remove belt from crankshaft timing belt pulley and camshaft timing belt pulley after pushing up the tensioner plate fully by finger as shown figure.

CAUTION:
- Never bend timing belt.
- After timing belt is removed, never turn camshaft and crankshaft independently more than such an extent as shown below. If turned, interference may occur among piston and valves, and parts related to piston and valves may be damaged.





12. Remove tensioner, tensioner plate, tensioner spring and spring damper.





INSPECTION
- Check timing belt for wear or crack. Replace it as necessary.
- Check tensioner for smooth rotation and rattle.

INSTALLATION





1. Install tensioner plate to tensioner. Insert lug of tensioner plate into hole of tensioner.





2. Install tensioner and tensioner plate.
Do not tighten the tensioner bolt and stud by wrench yet. Hand tighten only at this time.
Check to ensure that plate movement in arrow direction as shown in figure causes tensioner to move in the same direction.
If no associated movement between plate and tensioner occurs, remove tensioner and plate again and reinsert the plate lug into tensioner hole.





3. Check that timing mark on camshaft timing belt pulley is aligned with "V" mark on cylinder head cover. If not, align two marks by turning camshaft but be careful not to turn it more than its allowable turning range.





4. Check that punch mark on crankshaft timing belt pulley is aligned with arrow mark on oil pump case. If not, align two marks by turning crankshaft but be careful not to turn it more than its allowable turning range.





5. With two sets of marks aligned, install timing belt on two pulleys in such a way that the drive side of belt is free of any slack, and with tensioner plate pushed up by finger. And then install tensioner spring and spring damper as shown in figure, and hand tighten tensioner stud.

NOTE:
- When installing timing belt, match arrow mark (-->) on timing belt with rotating direction of crankshaft.
- In this state, No.4 piston is at top dead center of compression stroke.





6. To take up slack of timing belt, turn crankshaft two rotations clockwise after installing it. After making sure that belt is free from slack, tighten tensioner stud first and then tensioner bolt to each specified torque.
Then confirm again that two sets of marks are aligned respectively.

Tightening Torque
(a): 9 - 12 Nm (7.0 - 8.5 ft. lbs.)
(b): 24 - 30 Nm (17.5 - 21.5 ft. lbs.)





7. Install timing belt outside cover and resonator.
Before installing, make sure that seal is between water pump and oil pump case and another between water pump and cylinder head. (See figure.)





Tightening Torque (c): 9 - 12 Nm (7.0 - 8.5 ft. lbs.)





8. Remove crankshaft timing belt pulley bolt and install crankshaft pulley. With crankshaft locked.
Tighten crankshaft pulley bolts and timing belt pulley bolt.

Special Tool or equivalent (A): 09919-16020

Tightening Torque
(d): 105 - 115 Nm (76.0 - 83.0 ft. lbs.)
(e): 14 - 18 Nm (10.5 - 13.0 ft. lbs.)

9. Install water pump pulley and water pump belt. Adjust the belt tension to the specification.
10. Install air cleaner assembly.
12. Connect negative cable at battery.
