Dodge Viper (1992-2002) Special Anode Radiator Cap 18psi

Description

The Very Best Thing You Can Do for Your Viper Radiator!

This cap features a sacrificial anode that stops Electrolytic Metal Erosion (EME) inside the cooling system of your Viper’s engine. The cooling system of a Viper (and many other cars) carries a slight positive charge. This charge causes erosion of the 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 cooling system. You’ll be surprised to see the corrosion it shows after just two weeks — the anode will be eroding instead of your engine.

This item includes one Anode Radiator Cap.

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. The electricity seeks the shortest path, and impurities in the coolant often create a path of least resistance that the electricity follows. The source of this stray current is often poorly grounded electrical accessories. A missing engine or transmission ground strap can also cause the coolant to become electrified. Sometimes, the path of least resistance is through a radiator, heater hose, or heater core — all of which are well grounded and can conduct electricity from the engine to the chassis through the semi-conductive coolant.

Electrolysis can destroy your engine quickly. While very small voltage levels in the coolant system are normal, values greater than about one-tenth of a volt can trigger reactions between the coolant and metal components. Aluminum parts are especially vulnerable, resulting in pitting and scarring of surfaces such as the cylinder head and radiator welds. This corrosion can lead to coolant leaks and long-term damage to your engine.

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 parts and passages in your engine. The process is similar to how electrical discharge machines (EDM) remove material by passing current through metal — except here, the anode sacrifices itself to protect your engine components.

This is where the Anode Radiator Cap comes in to help!
