It is simple, it is only removes the Allen screws of the crankshaft, housings. the cyl.4 ..) then in the left. From the pulley it brings a hole in which the handle of a 6 mm drill enters just that it will also coincide with a drill that is behind the pulley (the position is +- on the 8h. On a clock). If you do not match you, the engine continues to turn until between the drill at all, when this passes, if the "zero" of the motor steering wheel is in its mark, you are at the point of draft. As advice I will tell you that you do not loosen the screws that the pulley brings, because the injection will go out. You can see images of the draft in other forums to get a better idea. (If you find it hard to put the belt, do not get nervous, that enters very fair..jejeje ..) That you do well, greetings !!
