Loosen tensioner pulley lock bolt and allow tensioner spring to apply tension to timing belt.
NOTE: Do not add additional tension.
Tighten tensioner pulley lock bolt to specified torque.
Tightening torque: 28~38 lb.ft (38~51 N.m, 3.9-5.2 kg.m)
Rotate crankshaft two full revolutions (clockwise only) and align timing mark on timing belt pulley with timing mark on engine block.

If they are not aligned, remove timing belt and start process from tensioner installation.
Measure timing belt deflection by applying moderate pressure midway between camshaft pulleys. If deflection is not correct, repeat from tensioner installation.
1. Deflection pressure: 22 lb. (98 N, 10 kg)
2. Deflection: 0.36~0.45 in. (9.0~11.0 mm)
