Timing Belt Installation

NOTE: The following procedure is for installing a new timing belt. If you are installing a used timing belt refer to the next procedure.

New Belt
1. Clean the timing belt pulleys, and upper and lower covers.





2. Set the timing belt drive pulley to TDC by aligning the TDC mark (A) on the tooth of the timing belt drive pulley with the pointer (B) on the oil pump.








3. Clean the camshaft pulleys. Set the camshaft pulleys to TDC by aligning the TDC marks (A) on the camshaft pulleys with the pointers (B) on the back covers.
4. Remove the battery clamp bolt from the back cover.
5. Remove the auto-tensioner.





6. Hold the auto-tensioner (A) with the maintenance bolt pointing up. Loosen and remove the maintenance bolt (B).

NOTE: Handle the auto-tensioner carefully so the oil inside does not spill or leak. If any of the oil has spilled or leaked out of the auto-tensioner, refill it with 5W-30 motor oil. The total capacity is 6.5 ml (0.22 fluid ounce).

7. Clamp the boss of the auto-tensioner in a soft-jawed vise. Do not grip the housing of the auto-tensioner.
8. Insert a flat blade screwdriver (c) into the maintenance hole. Place the holder (D) (P/N 14540-P8A-A01) on the auto-tensioner while turning the screwdriver clockwise to compress the bottom.

NOTE: Take care not to damage the threads or the gasket contact surface with the screwdriver.





9. Reinstall the maintenance bolt (A). Always use a new gasket (B).





10. Make sure no oil is leaking around the maintenance bolt, then install the auto-tensioner (A).

NOTE: Make sure the holder (B) stays in place.





11. Install the timing belt in a counter clockwise sequence starting with the drive pulley.





12. Tighten the idler pulley bolt.





13. Remove the holder.





14. Install the engine mount bracket.





15. Install the lower cover (A), front upper cover (B) and rear upper cover (C).
16. Clean the crankshaft pulley bolt and washer.





17. Clean all oil off the inside face (A) of the crankshaft pulley, and apply lubricant to the pulley bolt (B) and washer (C).





18. Install the crankshaft pulley, and tighten the bolt to 245 Nm (25.0 kgf-m, 181 ft. lbs.). Do not use an impact wrench.
- 1 Hold the pulley with holder handle (A) and holder attachment (B).
- 2 Tighten the bolt with a torque wrench and 19 mm rocket (C)
19. Rotate the crankshaft pulley about five or six turns clockwise so the timing belt positions on the pulleys.





20. Turn the crankshaft pulley so its white mark (A) lines up with the pointer (B).








21. Check the camshaft pulley marks.
- If the camshaft pulley marks are at TDC, go to step 22.
- If the camshaft pulley marks are not at TDC, remove the timing belt and repeat steps 2 through 20.





22. Install the dipstick and tube (A) with a new O-ring (B).
23. Install and adjust the P/S pump belt.
24. Install the alternator belt.





25. Install the side engine mount bracket, then tighten the mounting bolts in the numbered sequence shown

Used Belt
Follow this procedure when installing a used timing belt.
1. Clean the timing belt pulleys, and upper and lower covers.





2. Set the timing belt drive pulley to TDC by aligning the TDC mark (A) on the tooth of the timing belt drive pulley with the pointer (B) on the oil pump.








3. Clean the camshaft pulleys. Set the camshaft pulleys to TDC by aligning the TDC marks (A) on the camshaft pulleys with the pointers (B) on the back covers.
4. If the auto-tensioner has extended and the timing belt cannot be installed, remove and compress the auto-tensioner (refer to the New Belt Installation Procedure).





5. Install the timing belt in a counter clockwise sequence starting with the drive pulley. Take care not to damage the timing belt when installing it.





6. Tighten the idler pulley bolt.





7. Remove the battery clamp bolt from the back cover.





8. Install the engine mount bracket.





9. Install the lower cover (A), front upper cover (B) and rear upper cover (C).
10. Clean the crankshaft pulley bolt and washer.





11. Clean any oil off the inside face (A) of the crankshaft pulley, and apply lubricant to the pulley bolt (B) and washer (C).





12. Install the crankshaft pulley, and tighten the bolt to 245 Nm (25.0 kgf-m, 181 ft. lbs.). Do not use an impact wrench.
- 1 Hold the pulley with holder handle (A) and holder attachment (B).
- 2 Tighten the bolt with a torque wrench and 19 mm socket (C).
13. Rotate the crankshaft pulley about five or six turns clockwise so the timing belt positions on the pulleys.

15. Check the camshaft pulley marks (A).
- If the camshaft pulley marks are at TDC, go to step 16.
- If the camshaft pulley marks are not at TDC, remove the timing belt and repeat steps 2 through 14.





16. Install the dipstick and tube (A) with a new O-ring (B).
17. Install and adjust the P/S pump belt.
18. Install the alternator belt.





19. Install the side engine mount bracket, then tighten the mounting bolts in the numbered sequence shown.
