merc 160cdi - Merc A class 160cdi coolant change - piston power


Took bottom hose off radiator nothing came out?, Took top hose off and approx a pint or more came out all this with expansion tank cap off.

So is there a drain plug on the radiator or the block somewhere?

Please don't say i need a fangle dangle tool only merc supply to drain the coolant.!!
