The temperature of your vehicle’s coolant, oil, and other fluids are some of the most critical sensors. You can choose to continue to use your factory instrument cluster or gauge, but a OneGauge temperature sensor will provide a more exact idea, updated to the second, of your fluid temperatures. In order for the OneGauge to display the correct temperature reading, a OneGauge compatible sensor MUST be used. All sensors sold on the OneGauge website are compatible with OneGauge, but no others are guaranteed.
When purchasing a coolant temperature sensor for OneGauge, you’ll need to need to be able to answer the following questions:
1. Analog or Digital?
-Analog sensors come standard in most vehicles but are not as accurate. You MAY be able to choose to continue to use your current analog sensor but it will not be able to be plugged into your stock instrument cluster/gauge. Some vehicles have a port for a second temperature sensor, but not all.
-Digital sensors can be purchased from OneGauge. These are more accurate than analog sensors.
2. Sensor size: If purchasing a sensor from OneGauge, you’ll need to know the thread size of your port. Often a little internet research can tell you the size of your coolant temperature sensor port. Common sizes include 3/8″ NPT, 1/8″ NPT, M14x1.5, M16x1.5, and others.
