Coolant level switch (242): Function

WARNING: This page is about a different car, the 2005 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

The float will drop when the coolant level is low so that the ring magnet acts on the reed and closes the circuit.
