Hi, summer is coming and I am going to get my coolant change, which I can only get the G12+...no more G11s on the shelf? Do I just undo the hoses down the bottom and the hose to the bottle? After having all the coolant poured out should I just go get a water hose and wash out all the G11s? How long should I flush??? ALSO WHERE AND HOW SHOULD I GET THE OLD ONES TO?

I know theres heaps to answer:D

Cheers

when you refil the system use distilled water. you can buy it from the supermarket. dont use tap water because of all the additives and stuff.

Disconnect the lower radiator pipe...

Flush it out
Re-attach pipe
Pour 40%ish G12+ to 60%ish distilled water, into the coolant reservoir round thing, but not too quick because it will overflow, and come out the side, making you think you have a leak
Pump the top rad hose like a hand pump to get the fluid moving around

That's all I do until it reaches the right level...
ENJOY!

There's no need for distilled water in the cooling system.
Tap water is fine.
