Low Coolant Level Alarm Kit monitors the level of the coolant in the engine and notifies the user if any undesired drops in level occur. A loss of engine coolant can cause the water pump to lose pressure and can quickly overheat the engine. If a radiator hose frays, splits or begins to leak and the engine’s coolant is either low or lost, a temperature gauge will not be enough to alert the driver. This is where the Low Level Coolant Alarm adds security to assist in monitoring your engine’s coolant level.
