Index Liquid Probes
Index has developed two liquid sensing probes to improve the reliability and operation of your vehicle coolant level probes can increase the overall longevity of your vehicle engine. Water-In-Fuel probes keep your engine running smoothly without costly repairs or downtime.
- Single pin or dual pin. Internal diagnostic resistor available on two-pin probes.
- Tested to ensure long life in coolant.
Coolant Level Probes
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.
| Standard Fittings: | 1/4” NPT, 3/8” NPT, and 9/16” UNF |
| Terminal Styles: | Single threaded post with nut. |
| Operating Temperature Range: | -40 °F to 257 °F (-40 °C to 125 °C) |
Water-in-Fuel Probes
Index Water-in Fuel probes ensure the engine will not falter due to improper liquids entering the engine. These modules signal a dashboard or engine computer, which then triggers a display to the driver.
