Hi guys
I recall we had a discussion regarding operation and pressure ranges of
various freshwater cooling radiator caps a while back.
I have noticed antifreeze backing up into the overflow plastic bottle after
30 minute runs. It never runs back in until the cap is removed. The
bottle by necessity is mounted outboard and higher than the fill cap.
What range of cap should we use for fresh water cooling on the A 4?
How do we identify rating of a specific cap?
What is the physics behind it?
Thanks and Regards
