The Coolant Level Alarm from CARTEK consists of an aluminium sensor tube which is simply fitted in-line with the engine’s radiator hose. The coolant detection electronics are built into this sensor with a 3-pin plug for power input and an alarm signal output.

This alarm output can be used to alert the driver in a variety of ways including activating a dashboard LED indicator, audible buzzer or it can be used to provide the car’s ECU or driver display with a fault detection input signal.

The sensor also incorporates Red and Green LEDs which offers mechanics a continuous indication of the coolant status. This is especially useful if an engine is overheating without good reason or if an engine change has just occurred then this will show if the coolant has been filled correctly.
