What if one was to "hang" a zinc rod or whatever in the coolant tank, using a
piece of copper wire to hang it from. This wire could then be attached to the
engine using an existing bolt, or ground wire mounting point. Of course it
would be necessay to modify the cap for the coolant tank...
Any thoughts on this? Also, it would be easier to take a peek at to see if
it's working, as opposed to removing the allen head bolt and loosing coolant,
no?...
