Fig. 9 Valve Timing Marks:

Fig. 10 Timing Belt Tensioner:

Whenever the timing belt has broken or slipped significantly, a possibility of internal engine damage is present.
1. Remove timing belt covers, as described under TIMING BELT COVER.
2. Remove timing belt tensioner spring and retaining bolt.
3. Mark direction of rotation on timing belt, so it can be reinstalled in the same direction.
4. Remove timing belt from sprockets.
5. Check timing belt, tensioner and sprockets for wear and damage.
6. Align camshaft and crankshaft timing marks, Fig. 9.
7. Install timing belt with rotation mark placed during removal facing in the same direction.
8. Position timing belt tensioner to engine, then install tensioner bolt finger tight, Fig. 10.
9. Rotate crankshaft in direction of rotation two revolutions, aligning camshaft and crankshaft timing marks, Fig. 9.
10. Check to ensure timing marks are properly aligned. If not, realign.
11. Tighten timing belt tensioner bolt.
12. Measure deflection between crankshaft and camshaft sprockets. Deflection should be .35 to .39 inch at 22 pounds pressure. If deflection is not within limits, repeat steps 9 through 12.
13. Install timing belt covers as described under TIMING BELT COVER.
