cooling system electrolysis is the result of poor grounding and your
coolant being used as an electrical ground path. Aluminum is a fairly
active metal and in the presence of an electric field will act as an
anode and give up an electron to move current through the coolant
towards a ground source. The result is the aluminum metal being eaten
away and a gritty build up on the cathode side of the electrical
pathway. Commercial coolants have inhibitors that can slow this process
until the inhibitor gets used up. Tap water has ions in suspension that
can facilitate electrolysis.
What you need to do is provide lower resistance electrical pathways
between the engine and the battery ground. A good bare metal to bare
metal ground strap between the engine & frame is a good first step.
Triumphs with the battery ground going to the body also needs a strap
between the body and frame. If you have an alternator you should find a
ground post on the case. Run a wire from the alternator case to the frame.
Make sure your coolant gets changed per the directions and mix it with
distilled water to eliminate the ions in tap water that can help
facilitate electrolysis. Commercial coolants are formulated to minimize
electrolysis. Another thing you can do is replace your radiator drain
valve with a zinc plug. Zinc is more chemically active than aluminum so
will more easily give up its ions for electrical current flow. It
becomes the sacrificial anode giving of itself instead of the aluminum.
Good grounds, fresh coolant, distilled water, and a zinc radiator plug
together makes for happier aluminum bits in contact with coolant.
