Contact between the two metals is all it takes to get started. Coolant
actually has a slight neutralizer in it to help reduce this effect, but it
occurs nonetheless. And yes, it can happen in a year.

Yes, but there would have to be a steady flow of electrons for this to
occur. While dissimilar metals can react to eachother, this is
typically a very slow reaction to occur, certainly not something that
would have time to happen in only a year, and it would not be in
instantaneous type of failure. I'd have smelled little bits of coolant
until it got strong. I smelled no coolant and then *poof* there was the
smell.
We learned about this in my metals class last semester, so I might not
be right on, we didn't really do anything similar to this. Am I even
close here? The reaction would need some form of catalyst to get started.
