 To cause the cam pulleys to rotate, one must rotate the engine's crankshaft.  This is accomplished by applying torque to the nut on the forward end of the crankshaft using a socket and handle.  For best results, rotate the crankshaft clockwise only as viewed from the front of the car.

When the timing index on the crank pulley aligns with the timing mark on the engine front cover, and the index lines on the two cam gears align, the engine's #1 (forward) cylinder is at top dead center (TDC).  This is the reference point for all engine timing measurements.

If the timing belt tensioner is frozen, the adjuster should be loosened if possible.  The timing belt then should slide over its surface though some force might be required at the nut on the crankshaft.  If the timing belt breaks during the process (very unlikely), instantly stop trying to turn the crank; remove and repair the tensioner, install a new belt, then re-time the cam gears.  This can get tedious, but if done properly, the engine won't be harmed.
