I've stripped the water pump and the radiator off my car. My question is about the water jacket in the block. Is the hole for the water inlet flush with the low spot inside the block? Or is there still fluid in my engine below that spot? If so how do I remove it?
Yes, flush, that's it, just the head and the top few inches of the block hold water.
These drawings imply that the water inlet is the lowest point:

Here are some earlier threads on flushing out the water jackets:
Thanks Frank, that is good news. It's starting to get cold here in Pennsylvania, and as I have a number of items I want to address on this car over the winter, I didn't want to risk a cracked block do to ice expansion.
Thanks Mark, the picture labeled Cut No.5 shows what I'd hoped was the case. Also thanks for the link on how to flush out the head. As I said in Coolant System 2 thread I'd like to ditch the water pump if I can. I'm sure Dauntless Geezer will have some suggestions for alternate uses for it! ;>)
