Check whether the mark on the timing belt placed during detaching is
properly aligned with the matching mark on the crankshaft pulley. If not,
you need to move the mesh portion on the timing pulley until it is
precisely aligned. Align the timing belt with the matching mark of crank-
shaft timing pulley. For details, see Fig. 143.
5. Check Valve Timing
Loosen the bolts of belt tensioner (see Fig. 144) and rotate crankshaft
clockwise. Check whether each pulley is aligned with the timing mark
(Fig. 206). Otherwise, you need to reinstall it. Adjust the deflection of
timing belt (fig. 148), and tighten the bolts of belt tensioner with the
torque of 37N.m (Fig. 207).
