Spin the crank pulley untill u see 3 lil lines after the three single lines u will see 1 lil line by it self, line that lil line with the arrow on the lower timing belt cover and that is TDC then all u have to do is rotate the camshafts as stated above then put your timing belt on, rotate the engine by hand three complete rotations then line that single mark back on the crank pulley to the arrow on the timing belt cover. If your cams are facing up and in and u have the crank pulley rt on that mark, then all u hae to do is loosen the tensioner pulley bolt rotate the motor three teeth then tighten the tensioner pulley bolt and your done. Hope this helps
