Actually, threre isn't much difference between zinc and aluminum with respect
to the galvanic series, so I suspect that a sacrificial zinc annode would not
be very effective.

Subject: Re: [Fot] Aluminum Radiators and Electrolysis
Draining the radiator will get rid of electrolyte solution. In long term
situations using a Zinc sacrificial anode in the radiator could help. There is
a company making these..."Radcap" perhaps if you google it you will find out.
As I recall if you have a sensitive enough volt meter you can measure the
galvanic potential if you put one probe in the coolant solution and the other
on
the block. I have never done this personally. It is not worth the time save
for a science experiment.
