Here's a new idea. Cut a piece of clear hose, slide 2 anodes inside, close both ends with a tie wrap, attach it to bottom of radiator cap with copper wire and insert in radiator top tank. Clear hose with anodes lays on top of radiator tubes. I installed one anode made of zinc and another made of magnesium to see which corrodes faster. I believe it will be the magnesium anode after referring to the Electrolysis Chart. Also read that magnesium anodes work better in fresh water and zinc works better in salt water. Will be interesting to see what happens. Radiator is 18 year old Walker. Cap is 10 lb. Walker. Heads were installed in 1999 and never taken off since. (Glad I used head bolts, not studs.)
