Manufacturer details:

An Engine Saver® is a device which monitors the coolant level in an engine. Low coolant alarms are fitted to very few engines as standard equipment by manufacturers. When the coolant level drops due to a split hose, a stone through the radiator, a faulty pump seal or simply because the radiator cap wasn't replaced properly this device is designed to help warn you before any engine damage is done.

Over 70% of major engine blow-ups are caused by coolant loss going un-detected. In fact the normal temperature gauge will drop in cases of sudden coolant loss as the sensor in the cylinder head needs coolant around it to work properly. When a heater or radiator hose splits or blows the coolant is suddenly lost in a matter of seconds - the temperature gauge reading drops, the engine overheats and expensive damage is done. When a stone or rock damages the radiator core coolant is lost. If you are lucky the temperature gauge will rise and you may notice it in time. If you miss it or the coolant is lost rapidly, preventing the gauge from working, goodbye engine.

Same thing with a faulty water pump seal. Most water pump seals when they fail, first weep a little bit of coolant when the engine is running. When the engine is switched off for the night, the coolant steadily leaks out under the vehicle. Next morning the engine is started and the vehicle driven away. The coolant level is low, the temperature gauge doesn't read correctly and the engine cooks. An Engine Saver® can be fitted to any engine by a mechanic, auto electrician or home handyman in less than an hour without drilling holes in radiators or tanks and using normal hand tools.
