Tension Adjustment
AFTER BELT REPLACEMENT
If the timing belt was replaced (or to adjust tension on a used belt), follow the steps below.
1. Loosen tensioner lock nut, then turn tensioner clockwise and counterclockwise with hexagon wrench at least 2 times.
2. Tighten tensioner lock nut.
3. Turn crankshaft clockwise at least 2 times, then slowly set No. 1 piston at TDC on its compression stroke.
4. Measure deflection of timing belt midway between camshaft pulleys while pushing with 98 N (10 kg, 22 lb.) force.
Belt deflection when engine is cold (Reference value):
13 - 15 mm (0.51 - 0.59 inch)/98 N (10 kg, 22 lb.)
5. If belt deflection is not within specification, return to step 1 and repeat procedure.
