I was thinking about flushing my cooling system and i wanted to know what the best anti-freeze was to use? and whats the best ratio for n/a s4's of coolant to water?

i have the electric green coolant currently, but i heard that the pink coolant and the clear coolant was the best.

i have a 50/50 ratio, but i also heard 60/40 was better


if you havent noticed i hear alot of stuff

 

anyone? plz

 

is this the readline stuff you speak of if so i use it and yes what ive seen its pretty good i notice a big drop in the cooling i use it at 60/40 ratio

 

it doesn't matter what you use... pink....green... red.... blue.... they all work the same!!!! just use a 50/50 mix

 

they have blue? aw sick, i have to get that stuff...but there really isnt a difference? why would they do that if there wasnt a difference?

 

The blue antifreeze is Pentosin and it's used in VW/Audi and (maybe) BMW/Porsche.

There are differences in the coolants but if you've flushed your system and use distilled water you should be OK with any of them.
50/50 mix is what you want, especially going into winter.

 

ok thanks i guess ill pick...well i still dont no perhaps ill just pick a random color and see what happens...i hate the way that green looks anyway.....thanks

oh by the way whats your preference?

 

I use green, because I know it is compatible in terms of ingredients. Use 50/50 mix unless your ambient temps. indicate otherwise. Add a bottle of Redline Watter Wetter (sp?). Use distilled water for mixing, or just simplify (and pay more) and add the premixed stuff. Make sure it says premixed with distilled water, and safe for aluminum.

BTW, never mix different types of coolant (I know you didn't ask).
