How much coolant

Did a bleed-drain of my coolant the other week (just drained via the tap on the rad hose) and think I needed close to 2.5l to fill it again - I'm pretty sure for a full drain you need around the 3-4l mark, so a 5l bottle should be enough (I got ready-mixed)

get 2x bottles of g12 and put water to the rest but 1 will probably be enough if im honest as you wont loose loads and loads of water maybe only 2 litres max.

the mix should be 50/50 so just get a large bottle put 1 bottle of g12 then fill the empty g12 bottle with water poor that into larger bottle with the g12 and using the larger bottle fill the expansion tank until its done you will probably need about 4litres of mixed coolant so 2 litres of g12 dont forget once youve done the water pump you will need to run the car with the internal heaters on full wack! when they get hot the coolant has run through the whole system you will need to keep topping up the coolant as the level in the tank will drop as the engine warms and the water is pumper around the system. Hope this is helped :D

NO NO !!!

I've seen this mistake made so often by people changing
their coolant and then mix it 50/50 with water (!)

Please understand the difference between : coolant and anti-freeze.

(G12) "Coolant" is sold ready to use !! So it is pre-mixed.
Better not further dillute it !

Now , If you would buy concentrated G12 anti-freeze (where
would you get that anyway?) then you'd have to make your own mix out of it.
