Water is what cools your engine. Antifreeze is added to prevent water from freezing. You have it backwards. We use 50-50 to get the best of both. 50-50 will give you approximatly -35 C freezing point. And of course the antifreeze has anti-corrosion chemicals to keep the metals from reacting to water. As for pouring in antifreeze first…? Wierd method. If you pour in 4 L antifreeze then only pour 1 L water, then the mixture becomes 75-25. That will give you terrible cooling properties. --- _[View the full topic](https://forums.speedlife.net/t/overheating/130520)._
