In the service manual for the d16z6 it seems like it says all you have to do is loosen the tensioner to take the timing belt off. Am I missing something?
If you're replacing the timing belt too, you have to remove the crank pulley to get the lower timing belt cover off to get the new timing belt on.. I wish it were just that simple.

As for parts, I just got mine from the Honda dealer (especially for the timing belt), but I'm sure you can get the water pump from pretty much anywhere.
