You need to drain off some of it. Otherwise it will drain off out of the cylinders till they become empty.

Which is less than draining the whole system.

A quick way to just drain out of the heads is to pull the engine temp sensor. It sits just beside Num 1 cyl.

There is a petcock on the bottom of the radiator - less of a mess.

This is always how I have drained my radiator fluid.

my suggestion was only so he didn't drain the whole system.
