Two suggestions: (1) Use a garden hose to flush the heater core and (2) refill through the top radiator hose.
If you flush the engine block, don't mix the coolant. Just add the calculated amount of G-05 and fill the rest with water. Parking uphill (or at least not downhill) also helps to reduce trapped air.

I lucked out on Friday night and found that my local Wally Mart had Zerex G-05 on the shelf. So, now that I have the "right stuff" I plan to change the coolant in my 76 300D. Any good advice before I start? I had a bit of a scare when I changed the coolant in our 95 4Runner a couple of years ago. The thermostat wouldn't open up until it got quite hot and then it opened with a bang and the fluid flowed through. I was initially concerned that I might have damaged the engine but time has proven that all is still OK. Do you folks believe it is worth it to remove the thermostat? I have never done this in the past and not had any real issue with older North American vehicles.
