Yo what's going on everyone. My names Anthony. I've been a Volkswagen fan ever since I was a child and finally bought my first vw mk4 vr6 and would love to know as much as possible. Its stock and in great internal working condition. I wanna keep it stock and reliable as hell. I was wondering exactly what type of g12 coolant I need. Do I stay with g12? Do I upgrade to g12 plus, g13? I wanna flush the entire coolant system and start fresh for the winter. Any kind of help and guidance what so ever if highly appreciated fellas.
