never heard the continuity test for coolant, sounds pretty cool, it makes perfect sense as glycol base stuff shouldn't conduct much.
of course i will be obligated to take credit for it in my circle of influence. haha.

no the 6 series is a copper and large and the 7 is a new small plastic tank and are a lot of $ and only last about the same change or red antifreeze often to avoid damage an ez way to check antifreeze is that when antifreeze gets old it will conduct electricity so use a meter and see if it will conduct. If so replace the fld with only the red stuff

Sorry to say, but no
