Timing belt diagram for toyota corolla 2000 ae112

Easiest way to change a timing belt is to
first slightly slacken off the belt tensioner
carefully cut the old belt in half along its entire length while it is still on the engine.
remove the outer half only.
place the new belt on the pulleys up against the inner half of the old belt.
cut and remove the inner half of the old belt.
push the new belt fully into place.
re tension the belt as specified.

I want to know how the timing chain on my 2000Toyota corolla, like how low or how high do I set the piston then the 2 cam shaft and the crank shaft.
