Replacing my Intake Manifold Question

Pull the lower radiator hose off of the water pump. The drain plug in the radiator won't drain the block. The lower hose will drain a lot of coolant
Come on guys THINK. The block does not need to be drained to remove the intake.

Photo one shows the coolant level in the engine of you drain the radiator. It is to the bottom of those holes.

Photo 2 shows an engine with the heads on and no intake. You can plainly see that there will be no coolant spilled if you drain the radiator and remove the intake.

Pulling the lower hose doesn't do anything different to the coolant in the block. It will get some more out of the radiator.
