Coolant Level Probe
Index heavy-duty coolant probes sense when the coolant level drops below the measuring point and provides input to a dashboard or ECM warning system. Probes are available in one-pin (case ground) and two-pin configurations.
Water-in-Fuel Probe
Water-in-Fuel probes ensure the engine will not falter due to improper liquids entering the engine. The driver is notified when water has collected in the fuel filter housing and can remove the water before it causes problems.
