which is claimed to provide a six-way cure and prevention for irritating cooling system troubles such as radiator leaks, cylinder block seepage, water pump hqueak and over-heating. The makers state that when concentrated Radguard is added to water to be used in radiators 100 per cent cooling system efficiency is assured—power output is increased and engine wear reduced. Radguard chemically plates metal surfaces against corrosion, damps out vibrations and eliminates hot spots which cause overheating. It gives warning of corrosion danger from mechanical faults by changing from its normal colour red—to
yellow. The product is particularly effective in protecting aluminium engines and components.
Radguard can be used in all cooling systems up to 5.gal. capacity and remains effective for two years. It will work in all types of anti-freeze.
