[Fot] Aluminum Radiators and Electrolysis

[chasgee at aol.com]

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.

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.
