Any time you drain coolant, you will have voids in the castings where coolant will stay. It is that simple. If you drain the block and the radiator, you will get at least 90% of the old stuff out. That is good enough.
Roger that, Benzmac.
Any idea how to refill the block with coolant now that I have it all out? The 107 manual references a bleed screw on the thermostat (which I do not discern on the actual vehicle!), and also talks about jumping the aux coolant pump.
