If your intention is to re-use the coolant, you don't really have to drain any. All work can be done from above, just place a catch pan under the engine. If I recall, I lost a litre of fluid when I changed pump and thermostat. I didn't replace the entire pump with hoses, I just replaced the impeller section.
