I have a Mk2 Golf 1300.
What is the correct antifreeze ( G12 ) / water ratio to prevent corrosion in the coolant system?
Will 30% / 70% be alright? Where I live the lowest possible winter frost is only -5 C so I don't need 50 / 50
Absolutely fine. Still not sorted your cooling woes out?!
I have replaced the leaking radiator.
The leaking radiator only lasted for 28 k
