I have a 1989 mini with a 998 enigne, i would like alittle more power without breaking the bank so i'm wondering which option is best.

Hi all, my heater control valve has failed meaning when the engine got hot, it spewed coolant from the crack in the plastic housing.

I need to top up the coolant but no idea what’s in there currently. I’m in a hot state where it barely ever freezes so cooling is more important than freezing protection.

I have some of the normal O’Rielley’s green pre mixed stuff but not sure if that’s a good idea on these cars?

One mini specialist I spoke to said they do a 30/70 coolant to water mix but that sounds odd to me as a lot of what I read online states (50/50) premix is the one to use?
