I need to put some new coolant in my R32 GTR however I am unsure which one I need.

I have found OAT, Silicate, Comma G30, Comma G48.

Which one is the right one for my R32?

i think it depends on if you have the stock radiator or if you have a uprated aluminum one.

I have always used OAT in mine, but that is because i have a aluminum radiator and OAT offer high temp aluminum protection.

I'm sure someone can explain it better than me, but hope this helps for now.
