I'll just be the first to admit that I've never "flushed" coolant. Drain radiator, refill. Use distilled water. Disconnect lower coolant hose if that helps. That might only be ~half (2/3rds?) of it, but unless it was heavily contaminated, I figure it meets the spirit of the service. Pulling plugs out of any old block is an often difficult and risky procedure. Drain and refill twice if it's nasty. :dunno:
