As the title suggests really, want to do a really thorough coolant flush. More specifically something that's likely to brake down rust inside the water jackets and aid heat transfer from the cylinder wall.
Anyone got a product and or procedure they can recommend?
Thanks for the reply... It's a weekend car really so not used that often but when it is, it's generally fairly hard use! Perhaps mix as instructed and then go for a long hard drive?
Either that or I suppose I could use it as my commuter for a week or so
