I went to local Vaux dealer last week for soem service goods. I want to renew the cooant/antifreeze on my coupe turbo and he said that 2 litres will be fine. Its the pink GM stuff i have bought and it says on the bottle to dilute 1 part antifreeze to 1 part water. So is 2 litres of this stuff really enough???? My handbook doesnt state the capacity of the system of the z20let but im sure it is more than 4 litres.
Or should i go out and buy some more, but will be non vaux as not going all that way again!! Can 2 types of antifreeze be mixed also?
