Changing Coolant: Any parts that I should get just in case.

'6, are you thinking what I'm thinking?

The lower radiator hose will drain the radiator etc., but the thermostat will still hold some coolant in the engine so you need to undo other hoses too.

Yep exactly.

Which hoses did you take off?

Started with the bottom hose, then the top hose, then removed the hose on the right hand side of the cylinder head.

When I flushed through from the cylinder head side all of the water came through the top hose (Haynes said it would come out the bottom) so I guess that would mean that the thermostat was closed.

Not too worried as I have got a lot more antifreeze in the system than there was before. I'm guessing that the heater held on to a few litres.

The rest of the coolant is stuck in the crankcase water ways. Removing the bypass hose/thermostat would let it out. You get an antifreeze tester from halfords for a few quid, so you can check the mix is ok.
