Description
The very best thing you can do for your Prowler radiator!
This cap features a sacrificial anode that stops Electrolytic Metal Erosion (EME) inside the cooling system of your Prowler’s V-6 engine. The cooling system of a Prowler (and many other cars) carries a slight positive charge, which causes erosion of aluminum components in contact with the coolant. The sacrificial anode is immersed in the coolant tank and, because it’s a softer metal, the EME attacks it instead. This extends the life of all metal components in the coolant system. You’ll be surprised to see the corrosion it begins to show after just two weeks. The anode erodes instead of your $800 radiator. Fits all model years.
Explanation of Electrolysis
One failure mode associated with dirty coolant is known as electrolysis. Electrolysis occurs when stray negatively charged ions (electrical current) travel through the engine coolant. Electricity attempts to find the shortest path, and impurities in the coolant often generate a path of least resistance. The source of this stray electricity is often electrical engine accessories that are not properly grounded. A missing engine or transmission ground strap can also cause the coolant to become electrified. Sometimes the path of least resistance becomes the radiator, a heater hose, or the heater core. These components are usually well grounded and provide a path from the engine to the chassis through the semi-conductive coolant.
Electrolysis can destroy your engine quickly. Although it is semi-normal to have very small amounts of voltage potential in your coolant system, values greater than about one-tenth of a volt can start reactions between the coolant and the engine’s metal components. Electrolysis primarily affects aluminum engine parts, causing pitting and scarring of the aluminum surface. This deterioration can result in coolant leaks, especially around radiator welds. Aluminum components, such as engine blocks and heads, are the most vulnerable. Electrolysis damage is often visible, such as erosion around the thermostat area of a cylinder head.
Adding an Anode Radiator Cap to the cooling system significantly reduces this erosion by providing positively charged ions to attract the negatively charged ions in the coolant. Because the anode is softer than aluminum, it erodes instead of the aluminum engine parts and coolant passages. This process works similarly to electrical discharge machines (EDM), which zap away bits of metal with electrical current. Unfortunately, electrolysis damages engine parts the same way. The Anode Radiator Cap protects your engine by ensuring the anode wears out instead of expensive components.
This is where the Anode Radiator Cap helps!
