Zinc anode for engine
CASTOLDI
Zinc Castoldi anode CST-802403/1 is suitable for use in engine cooling circuits to help protect the dissimilar metals of heat exchangers, coolers and casings from electrolytic corrosion.
Internal Engine anode
Heat exchanger / Cooler Anode
Gearbox oil cooler anode
Installation
The anode must be in direct contact with the metal it protects : never paint around an anode or the anode itself.
When Should Anodes Be Replaced ?
Anodes deterioration rate may fluctuate according to the mooring area, water salinity, PH and temperature, potential electrical failure on board, and so on. We recommend to replace anodes every year when doing the boat antifouling/launching. In all cases, anodes deterioration should always be watched carefully together with the condition of the metal parts they protect.
