Timing Belt: Service and Repair

TIMING BELT REMOVAL

CAUTION:
- Do not bend or twist timing belt too tightly.
- After removing timing belt, do not rotate crankshaft and camshaft separately because valves will hit piston head.
- Ensure timing belt, timing belt camshaft sprocket, crankshaft sprocket and belt tensioner are clean and free from oil or water.
- Before installing timing belt, confirm that No.1 cylinder is set at T.D.C. on compression stroke.
- Align arrow on timing belt forward.
- Align white lines on timing belt with punch mark on camshaft sprocket and crankshaft sprocket.
- Adjust belt tension with all spark plugs removed.





1. Drain coolant.
2. Remove upper radiator hose.





3. Remove right side under cover.
4. Remove drive belts for power steering pump and compressor.
5. Remove water pump pulley.




6. Remove crank angle sensor.

NOTE: Put aligning mark on crank angle sensor and timing belt cover.





7. Support or hang the engine.





8. Remove engine mount bracket.





9. Remove front upper timing belt cover.

10. Align timing marks on crank pulley sprockets.





11. Remove crankshaft pulley.

NOTE: Crankshaft pulley is accessible after removing side cover from inside R.H. wheel house.

12. Remove front lower timing belt cover.





13. Loosen tensioner pulley nut to loosen timing belt.
14. Remove timing belt.

CAUTION:
After removing timing belt, do not rotate crankshaft and camshaft separately because valves will hit piston heads.





15. Inspect belt tensioner and idler pulley for the following:
a. Visually check belt tensioner and idler pulley for seizure, rust and any evidence of breaks.
b. Confirm that tensioner and idler pulley can be rotated smoothly.
c. Visually check tensioner pulley return spring for corrosion, distortion and any abnormal signs.

TIMING BELT INSTALLATION





1. Install crankshaft sprocket with sprocket plate.





2. Confirm that No.1 cylinder is set at T.D.C. on its compression stroke.





3. Install timing belt.

NOTE: Align timing marks on timing belt and sprockets.





4. Loosen tensioner pulley nut.
5. Install lower timing belt.
6. Install crank pulley with washer.

TORQUE: 142 - 152N.m (105 - 112 ft. lbs.)

7. Rotate crankshaft 2 turns completely.
8. Tighten tensioner pulley nut.

TORQUE: 22 - 29 N.m (16 - 22 ft. lbs.)
