call me too pragmatic, too old, too simple, lazy or whatever but i would let sleeping dogs lay.
Since its not leaking or causing problems I would leave it alone. Sure being able to remove it would be fantastic and preferred but the potential of buggering it up and the can of worms that would cause I would leave it alone.
I would fill flush / repeat with a good cleaner (3x flush) multiple time and use lower rad hose as the drain point. Sure maybe not complete drain but do it a few times with a cleaner if you want will move you in the right direction by a good amount.
Then when comes time to fill you may not be able to get all the water out from last flush. If you manual tells you 4 quarts is cooling system capacity I would start by adding 2.5 quarts of pure antifreeze first not the 50/50 mix stuff as it will get diluted further by the residual water left in system. We here always shoot for a 70/30 mixture. I think those who use 50/50 for Canadian rad's maybe inviting problems into their lives that need not be let in.
Then top of with remaining water so maybe 1 quart of water as maybe other fluid is left behind. So you will easily see if full (then you have something like 2/3 - 1/3 mix which is no big deal. As since you are from Canada maybe 50/50 is not strong enough like many others mention. Then top up remaining water slowly to get to the desired concentration. Knowing your capacity first, then adding straight antifreeze to what your final desired mix should be then adding distilled water at end to make up to final capacity watching total liquid added amount to ensure not too watered down just in case the 4 qt research you will make was wrong you can add more antifreeze or water to finalize final mix at the very last level adjustment is what I would do.
hate to see you back here in a week or so looking for a different fix cause the repair went south.
cheers
