    based on another post regarding which glycol brand to buy, I purchased a gallon of "Cryo-Tek 100 Anti-Freeze."  Low and behold, the warnings on the container state "Cryo-Tek is not recommended for "systems containing aluminum and operating temperatures over 160*F/70*C."  Does this mean its safe for aluminum systems under 160*F?  Do the internal Alde components get hotter than 160*?  I also have a gallon of Pestone LowTox anti-freeze.  The label specifically states it is safe for aluminum systems (but no temperature limit).
