Phosphate-free Antifreeze?

[Alan Cordeiro]

Prestone "extended life" GM-Dexcool approved (red color) coolant
and the Pentosin brand to name a couple...

Both products are safe for use with Aluminum radiators, especially
when dissimilar metals (cast iron block and the aluminum) are used which
can cause the galvanic effect to make the corrosion speed up.
