I took top and bottom radiator hose off.Suprized how little came out.Flushed out radiator with hose.New antifreeze in but could only fit about 3-4 liters in before radiator full.Supposed to be 12 liters coolant.Any ideas!

You forgot about all the coolant that's still sitting in the engine. that has to come out too. Also, what type of car are we talking about!

v6 commodore I knew there would be coolant in motor but not that much.Motor was cold which prob didn't help (thermostat closed.)

Do it cold, if you drain a warm engine you can crack the heads, or warp them.The engine overheats with no water in it.Its a tricky one as whats happened with the thermostat closed the water has stayed in the engine block.It only dribbles out, so you need to wait ages.Anyway, rule of thumb, never do it hot.

I uumed and aahed about that but found a modern antifreeze that said it exceeded all GM specs and said it was suitable for all modern cars.since mine is 10 yrs old decided anti freeze alone was good enough. Problem is now I have a mix of old (goldy colour) and new (green) antifreeze.Thanks

Those colours should be OK for an Aussie car!

I was told you don't mix coolants. Stick with the same that is in there. Unless your gold one was ancient green coolant watered down lol
