This cap features a sacrificial anode that stops Electrolytic Metal Erosion (EME) inside the cooling system of your Viper and/or RAM SRT engines. 16 lb. cap fits many other vehicles too. Great for all engines with aluminum heads and/or block! The cooling system of a Viper, Ram SRT-10,and many other cars 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. You’ll be stunned to see the corrosion it begins to show after just two weeks. Fits all model year Vipers andRam SRT-10.
