Which Coolant?

[Fixxxer]

Hi,

Ok so when I rip off my turbo coolant lines again, I'm going to do a coolant change aswell.

I can't find any recommendations on the type of coolant to use, only that the R32 maintenance thread says use a 50:50 anti-freeze /anti-boil mix (I don't need anti-freeze, I'm in brisbane). Is this a glycol coolant? or non-glycol coolant? What ratio glycol (g/L)? Autobarn said that depending on engine/head material (cast iron vs alloy/aluminium) will need different types of coolant to stop corrosion, etc...

What brands do people use? I'm just looking at one of those 1L bottles that makes up to 10L.

Castrol?

Tectalloy (sp)?

Brisbane is colder than sydney in the morning!!!

Anyways to the point pickup some nulon mix up crap and some distilled water mix it up a little higher at 60:40 (60% nulon 40% WATER) \

NULON is recommended by alm,ost all mechanics

Be careful mixing coolant stronger than 50:50. It's job is to prevent corrosion, lower the freezing point and raise the boiling point but it isn't as good at transfering heat as pure water. Making the mix too strong can reduce the effieciency of your cooling system.

Nulon ftw..... mix it yourself but only go slightly above whats reccomended as far as percentage of concentrate

With mine I found 30% Nulon and 70% distilled water to be a better mix - particularly when doing track days.

According to Nulon more = better cooling properties.. I believe they suggest 70% for best cooling i.e race conditions Im not sure why (I may be wrong as its from memory - which has prooved several times to be pretty unreliable.)
