Default Re: cooling system anti-corrosion products

Prestone makes a combination anti-corrosive and water pump lubricant. However, I also like the zinc bar that the corrosion in the system will attack instead of the engine/cooling system internals. The best thing is to never let corrosion start to begin with because there is noting on the market that will thoroughly clean a cooling system once corrosion has started.
