Very good point!

Let's not forget that more H2O is better heat
transfer.....................contrary to street wisdom water is still the
best medium to move heat.

You all take care, now,

NO!  Use the coolant that originally was designed for the vehicle.
Most older Audis use blue Pentosin; only newer Audis use the "pink
stuff".   Consult the owner's manual to be sure; it'll give the
correct part number and from that you'll know whether it uses the
blue or pink/red stuff.

Further, one need not hunt for "vapor distilled" water- deionized or
distilled(any method) is fine- you're just looking for very low
mineral content.  Additionally, not everyone should mix to 50/50.
Mix according to the temperature chart on the bottle, as 50/50
protects down to -37 C according to my Pentosin coolant bottle.  It
doesn't even remotely get that cold here in MA, so I mixed more like
1:2 (good for -20 degrees C).
