Radiator Cap Sacrificial Anode Viper 92-17800-1925
Fits all Viper models 1992-2017. Cap fits many other vehicles, too.
Great for all engines with aluminum heads and/or block. This cap features a sacrificial anode that stops Electrolytic Metal Erosion (EME) inside the cooling system. The cooling system carries a slight positive charge. This charge will cause 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 the anode instead. Extends the life of all metal components in the coolant system. This is a wear item that you will see the anode decay and will need to be replaced.
