Radiator Anode Zinc

The Radiator Anode Zinc by FLEX-A-LITE is a sacrificial corrosion protection component designed specifically for freshwater and saltwater cooling systems in marine engines and closed-loop radiators. It addresses the common issue of galvanic corrosion that can lead to radiator failure and engine damage, making it essential for boaters and anglers who rely on their equipment.

This zinc anode utilizes cathodic protection, oxidizing in place of more noble metals to protect the radiator core and water passages. Measuring 4.35 x 2.35 x 4.75 inches and weighing just 0.21 lbs, it can be threaded or bolted into existing radiator drain plugs or mounting bosses, requiring minimal modification to your cooling system. Regular inspection is recommended to ensure the zinc has not depleted significantly.

Ideal for inboard engines, outboard cooling systems, and both aftermarket and OEM radiators, this anode is particularly beneficial in mineral-rich or corrosive water conditions. While the service life can vary, it is generally effective for multiple seasons in freshwater and may require more frequent replacement in saltwater environments depending on usage and conditions.
