So... I hate Haynes repair guide... or moreso the fact the they give low quality pictures.(yes i should have gotten a Chilton)...

1) i'd like to know if it's necessary to open all bleeder screws in order to completely drain the system, and if so I've yet to find the one for the heater core(picture doesn't help in book)

2) the engine block drain screw/plug, where the heck is it? the picture shows two round white things(im sure that's when they're new), and an arrow pointing to a screw, and the rest of the picture is too dark to make out where it is...

3) anything i should do other than what's listed in a repair guide for flushing the system

thanks!
