Just wondering out loud... I'd bet some cars have either all-plastic 
radiators, or, maybe plastic heater cores for the A/C. Maybe that would 
remove the issues of metal ions from the heat-exchanger. Undoubtedly 
less efficient at removing heat from the water than metal, but size 
cures a lot of ills.
