The Knock sensors are the block drains. Pull those and all the coolant will come out of the block.

My memory must be getting bad since when I changed the coolant and hoses last fall, I pulled the knock sensors to completely drain the block. However, I forgot that'* how I did it until I saw the above.

2000SilverBullet is on a distinguished road

The shop vac idea works.....if you have the heads off and want to clean down deep into the water jackets.

When I rebuilt my last engine, I cleaned out about 4 cups of casting sand inside the passages. It had all settled in one corner. I was amazed at how much was in there.
