Drain and change Dex-Cool Generator Coolant

[Cliffm]

Anyone drain and change their Dex-Cool Generator coolant? I have a Kohler 7.3E and the overflow tank coolant color looks more brown than orange.

Is there a drain plug or other trick to draining most of the coolant from the Generator, before topping it off with "fresh orange" Coolant.

As always, informative suggestions much appreciated.

Based on input from forum member, I'm going forward with utilizing a hand transfer pump, first sucking out as much of the old coolant as I can, then reversing the pump to transfer fluid into the generator, first via the radiator cap, and then thru the "air bleed" plug hole via a poly/barb adaptor, hopefully drawing out air and stopping when I get fluid.

So far I've gathered Transfer pump via Harbor Freight, and pipe plug adapter via Ace Hardware, 50/50 DexCool coolant AutoZone.
