Directions for use
Star Engine Cooling Water Treatment has been designed for use in all common types of engine cooling water systems and will protect ferrous metals, copper and copper alloys and all other metals including aluminium components. It will not affect rubber gaskets or other non-metallic components within the cooling system.
Engine cooling systems should be drained, flushed and if necessary, chemically cleaned, to remove old rust and scale deposits before treatment can begin. Star Engine Cooling Water Treatment is easy to apply as received and is fully compatible with water in ethylene glycol solutions. It contains an anti-scalant which helps to keep engine systems clean and free from corrosion and scale formation and maintains design heat transfer efficiencies and extends the life of the engine.
Cases of unusual coolant loss should be checked and remedial action taken and should be introduced during circulation of the cooling water.
Dilutions
The treatment is best added by means of a feeder installed on a by-pass to the circulating system or in smaller systems, it can be added directly to the header tank.
Initial treatment is at a rate of 75 litres per 1m3 of coolant to give a control level of 700 to 1500ppm as nitrite (1000 to 2250ppm as sodium nitrite), pH 8.3 to 10.0.
Overdosing is not harmful to the system. Control by a simple test for nitrite and pH.
