Red Line WaterWetter® is designed to provide improved metal wetting and excellent corrosion inhibition when added to plain water or a glycol coolant.
The most poorly maintained system in an automobile is usually the cooling system. Maintenance is quite simple and only required once each year, but most vehicle owners never routinely change the coolant or replenish the corrosion inhibitors which are required for trouble-free operation.
Proper cooling system maintenance is very critical for most modern engines which utilize more aluminum. Aluminum has a very high corrosion potential, even higher than zinc, which is very widely used as a sacrificial anode.
The only property which enables aluminum to be used in a cooling system is that it will form protective films under the proper conditions which will prevent the uncontrolled corrosive attack of acids or bases. Poor aluminum corrosion inhibition will cause the dissolution of aluminum at the heat rejection surfaces, weakening the cooling system walls and water pump casing and weakening the head gasket mating surfaces.
These corrosion products will then form deposits on the lower temperature surfaces such as in radiator tubes which have very poor heat transfer properties, causing a significant reduction in the cooling ability of the entire system.
Red Line WaterWetter® will provide the proper corrosion inhibition for all common cooling system metals, including aluminum, cast iron, steel, copper, brass, and lead. Water has twice the heat transfer capability when compared to 50% glycol antifreeze/coolant in water.
Most passenger automobiles have a cooling system designed to reject sufficient heat under normal operating conditions using a 50/50 glycol solution in water. However, in racing applications, the use of water and WaterWetter® will enable the use of smaller radiator systems, which means less frontal drag, and it will also reduce cylinder head temperatures, even when compared to water alone, which means more spark advance may be used to improve engine torque.
