The new Ironman 4x4 Low Water Alarm Kit is perfect for anyone doing some remote outback travelling or in fact any driving at all. This new system could be the engine saver in such a case if you damage a cooling system hose or have a coolant leak. With the ability to sense a negative current in the water of the radiator, when the water drops below the probe, an alarm and warning light are activated. This system will be activated prior to movement in your temperature gauge. This kit includes fittings for a plastic header tank and also a metal header tank.
