How do you defeat the fifth colossus on shadow of the colossus?

to defeat the 9th colossus you must go behind one of the close geysers and Dodge its attacks then continue this until it reaches you.Then when the geyser goes up the colossus will be under it..... then grab your bow and arrow and shoot the legs on the ground because they have vitals spots on them shoot the two of them and he will fall on his back then go around and there will be some slots then he will turn over then pull wander up on to his back then travel up to his head.......
