Coolant change, what to use...

[Cally]

Going to change the coolant on my FD as I am doing a service, but I am unsure what coolant to use and where to get it as I know some can encourage rust on rotors or something?!
I have green coolant at the moment which would have been put in when RE:WORX rebuilt the engine, so want to use the same/similar stuff.
I have done a search but most of the posts are people panicing about water seal failure or coolant loss. So what stuff would people reccommend and how much do I need, also what mixture do people recommend? I have heard 50/50 but also heard folk saying this is too much, with summer coming up what do people suggest?


Cheers.

Have a look at the \'Radiator Coolant\' post, just a few threads down in the General Technical Posts. Some advice in there.

But anything EG coolant, pink stuff isn\'t supposed to be too good however so anyting blue of green

Also I\'d go for a 30% coolant / 70% distilled water mix as water has better cooling properties.

I use a 40% mix because it stays in for 3 years and if thats the case I have to protect for the worst forseeable winter condition in Doncaster, which is relatively sheltered.(Car is garaged as well, not out in the open). Also I don\'t run the car hard so the cooling system is never under stress like on track days. Bluecol for me every time for ordinary road use.
