Mike - Markus and Jonathan have the right idea about leaving the block drains alone and flush with water.  Make sure you leave your heat temps. on high to circulate all the old stuff out of the car.

Mike,
 
I wouldn't bother, honestly.  I know someone who did this and it turned into quite a nightmare.  I'd simply drain the radiator, refill with water, run the car for a bit, then drain it again and refill with 50/50.  If you really want to go nuts, you can do the acid flush, but I've also heard cautions on doing that as it could loosen things and clog the system.

I suspect its been 4 or 5 years or longer since the antifreeze has been change on my 1991 SEC. I have the car up on ramps, new MB antifreeze ready to add. My dilemma is I can't get the engine block drain plugs loose to properly drain all the fluid. If I'm reading the Service Manual correctly the location of the plugs correspond to a 6mm allen socket plug. I have the plugs drenched with liquid wrench. Any suggestion how to get these buggers out?
Thanks Mike
