2. Verify that the camshaft pulley marks are aligned with the
cylinder head cover marks.
3. Install the timing belt so that there is no looseness at the
tension side.
Caution
l Do not turn the crankshaft counterclockwise.
4. Turn the crankshaft two turns clockwise, and align the tim-
ing belt pulley mark with the timing mark.
5. Verify that the camshaft pulley marks are aligned with the
cylinder head cover mark.
if not aligned, remove the timing belt and repeat from ten-
sioner installation.
6. Loosen the tensioner lock bolt to apply tension to the tim-
ing belt.
Caution
l Be sure not to apply tension other than that of the
tensioner spring.
7. Tighten the tensioner lock bolt.
Tightening torque:
19-25 N#m (1.9-2.6 m-kg, 14-19 ft-lb)
8. Turn the crankshaft 2 turns clockwise and verify that the
timing marks are correctly aligned.
9. Measure the timing belt deflection by applying moderate
pressure (96 N, 10 kg, 22 lb) midway between the crank-
shaft pulley and the camshaft pulley.
If the timing belt deflection is not correct, temporarily se-
cure tensioner lock bolt so the spring is fully extended and
repeat steps 4-8 above or replace the tensioner spring.
Deflection:
