[Fot] Aluminum Radiators and Electrolysis

[Marx Christian tr4-racing]

As far in know is the combination of aluminium and cast iron a unlucky
combination.
A copper core radiator is the protected part which is passivated very quickly
and the electrolysis.
With aluminium the core try to protect itself but it is only building a jelly
that is pumped through the system.
So a special fluid is needed with cast iron engine or the aluminium core will
get porose one day.
