3. Turn the crankshaft pulley clockwise
(Figure 5-158, (1)) to align the timing marks of
camshaft timing pulleys No. 1 and No. 2 with
the BDC mark. NOTICE: If the timing belt is
disconnected and the crankshaft pulley is
rotated, engine damage will result from the
piston head and intake/exhaust valve heads
contacting. NEVER turn the crankshaft with the
timing belt disconnected and always make sure
to set the crankshaft pulley at the correct angle
when installing the belt.
