Electrolysis in cooling systems

[Frederick Smith]

Electrolysis is an increasing problem, particularly in alloy engines. 
Bad grounds on electrical components is usually the cause. The higher 
the current draw of the offending component the more severe the 
errosion. (A bad starter ground can eat your radiator very quickly, as 
well as block and cyl. head surfaces. Try these links for a good report 
on the problem.
