ok, Mike, even tho your chart text is too small for me to read, I have a coolant question...

How often do you need to flush & refill a coolant?

specifically, this is in a VW Vanagon (AL motor parts, so requires an AL compatible coolant)

some people say to just test it every 2 years and add some of the Subaru coolant conditioner (and they leave it unchanged for many years -- one guy has had it in there for > 10 years)

others will change/flush their coolant every 2 years on the dot (even tho the setup with R engine and F radiator) makes it tough to do
