15. Disconnect crankshaft position sensor (CKP sensor) connectors.
16. Place transaxle in NEUTRAL.

Camshaft Sprocket Marks:






17. Set engine to TDC on No. 1 cylinder.
Ensure that "white" mark on crankshaft vibration damper and pulley aligns with 0 degree index mark on lower outer timing belt cover and that marks on intake camshaft sprockets align with index marks on upper inner timing belt cover.
18. Raise vehicle on a hoist.
19. Remove RH front wheel and tire assembly.
20. Loosen front fender splash shield and place out of the way.
21. Remove crankshaft vibration damper and pulley using Steering Wheel Puller T67L-3600-A, Step Plate Adapter D80L-630-3 and Screw and Washer Set T89P-6701-A or equivalent.
22. Remove lower outer timing belt cover.
23. Remove center outer timing belt cover and disconnect crankshaft position sensor (CKP sensor) wire and grommet from the slot in the outer timing belt cover and stud on water pump.

Timing Belt Tensioner Idler Pulley:






24. Loosen timing belt tensioner idler pulley, rotate idler pulley 180 degrees clockwise using an Allen wrench, and tighten timing belt tensioner idler pulley nut to hold pulley in the "unload position."
25. Lower vehicle.
26. Remove timing belt.

Installation

CAUTION:
- Before installing timing belt, inspect if for cracks, wear or other damage. Replace if damaged.
- Do not allow timing belt to come in contact with gasoline, oil, water, coolant or steam.
- Do not turn belt inside out or twist belt.
- Always store belt in a cool dark place.
- Always keep belt in protective packaging until ready for use.
- Never hit or squeeze belt with hammer or screwdriver.






1. Ensure engine is at TDC on No. 1 cylinder.
Check that camshaft sprocket marks line up with index marks on upper inner timing belt cover and that crankshaft sprocket aligns with index mark on oil pump.

Note: The timing belt has three yellow lines. Each line aligns with the index marks shown.

2. Install timing belt on crankshaft sprocket and route to camshaft sprockets.
Lettering on belt "KOA" should be readable from rear of engine (top of lettering to front of engine). Also ensure that the yellow lines are aligned with the index marks on all the sprockets.
3. Release timing belt tensioner idler pulley locknut and leave nut loose.
4. Raise vehicle on hoist.
5. Install center outer timing belt cover.
Ensure crankshaft position sensor wiring and grommet are installed and routed properly.

Yellow Index Mark:






8. Rotate crankshaft two revolutions in the clockwise direction until the yellow index mark on crankshaft vibration damper and pulley aligns with 0 degree index mark on lower outer timing belt cover.
9. Remove plastic door in the lower timing belt cover.
Tighten timing belt tensioner idler pulley lock nut to 33-51 Nm (24-38 ft lbs) and install plastic door.

White Index Mark:






10. Rotate crankshaft 60 degrees more in the clockwise direction until the white index mark on crankshaft vibration damper and pulley aligns with 0 degree index mark on lower outer timing belt cover.
11. Lower vehicle.
12. Ensure index marks on camshaft sprockets align with index marks on upper inner timing belt cover.
13. Route crankshaft position sensor wiring and connect with fuel charging wiring.
14. Install upper outer timing belt cover.
Tighten retaining bolts to 7-11 Nm (62-97 In lbs).
15. Install water pump pulley.
