draining cooling system how to:

[spongebob]

My engine has 100% water in it and getting ready for winter, Im ready
for draining it and putting in anti-freeze..

as you know there's no drain fitting (stupid move)..how can I make sure all the water is out?

I know I have to pull the lower hose, but what else??

Pulling the lower hose fully drains the radiator (easier than accessing the drain petcock, if has one), but the block only drains to the water pump level. To drain the lower block, you'll need to remove the block drain plugs, one one each side. Replacing the block heater will also drain most of the coolant, and near completely on the one side. The drain plugs are at the left/front, forward of the engine mount, and right/rear, behind the starter. It's reported by some that they are painted or marked yellow, but I didn't find any yellow on mine. It's a very early LB7, so they yellow paint may have not yet arrived at the time.

freeze plugs???

Freeze plugs may be more thorough, but I was referring to the threaded drain plugs.
